At what temperature do bugs and their eggs die. What temperature is fatal for bedbugs and their larvae? Exposure to high and low temperatures: what is the most effective way to kill insects? Bed bugs at what temperature minus died

It is known that house bugs are afraid of frost. But answer how much bugs and frost Worth taking out furniture on a cold winter day is not easy. Bedbugs die in the cold not right away. Depending on the temperature threshold, the time required for their complete destruction can be different. In which cases the bugs die, and in which they just sleep, scientific experiments will show.

The answer to the question of are bedbugs afraid of frost, suggests how to minimize insecticide spraying. This is important for those who can hardly tolerate the consequences of such procedures, for example, allergy sufferers. If house bugs do die in the cold, it is wise to use it.

In addition, chemical agents, as practice has shown, are far from omnipotent against insects. Bedbugs have adapted to 90% of insecticides, and disinfectologists are looking for alternative ways to control these insects.

Finally, our country is characterized by long winter periods with frosty weather. Whether it is rational to use the "climatic weapon" for the season - to take out the contaminated furniture or cool the room, we will figure it out further.

Does frost kill bedbugs

It is logical to assume that, like any heat-loving insect that avoids, bedbugs will die in the cold.

Scientifically, extreme temperatures can cause protein denaturation in insects and, as a result, irreversible damage to nerves and muscles. This effect leads to the fact that bedbugs die in the cold. Or not?

Not so simple. As living things, insects are endowed with defense mechanisms against various stressful situations that they fear.

You might be surprised to learn that bed bugs, whose body is 70% water, survive in severe frosts for several hours and even days!

Bed bugs are resistant to low temperatures for a number of reasons.

First, the bodies of individual insects contain high concentrations of antifreeze proteins and cryoprotectants such as glycerin, which lower the freezing point of body fluids below the freezing point of water. This directly affects how bed bugs tolerate winter and frost.

Secondly, some individuals can withstand hypothermia... This is the name given to a condition in which a liquid does not freeze even when the temperature drops well below the freezing mark. How does this happen?

For example, pure water, consisting only of oxygen and hydrogen, is supercooled down to -42˚ without being covered with ice. Natural water containing impurities freezes at 0˚С. These impurities are crystal-forming agents around which ice forms and spreads. The process is called heterogeneous freezing.

But since there are no such substances in pure water, crystallization occurs spontaneously, as soon as the critical temperature of hypothermia is reached. Such freezing is called homogeneous. When the slightest ice crystal appears, supercooled water begins to freeze quickly.

In this video, supercooled distilled water quickly crystallizes after shaking the bottle:

Of course, insects freeze and die during this process. Is it any surprise that bedbugs, once in the cold, try to minimize the water content in the body and avoid external contact with ice crystals.

Thirdly, hypothermia is associated with diapause- a period of passive life cycle, during which the metabolic rate decreases and development is suspended. Before entering diapause, the insect empties its intestines in order to remove the same crystal-forming agents that are contained in ordinary water impurities.

The ability of bedbugs to go without food for a year and withstand a slight frost has developed with the ability to go into a state of "hibernation".

Scientists have already found bacteria that can provoke crystallization. In the future, these studies will help in the development of insecticides that reduce the resistance of insects to cold.

However, some frost-resistant species have developed a different defense mechanism. At the extracellular level, they can withstand a certain degree of freezing, and deliberately promote crystallization at higher temperatures to prevent death from spontaneous homogeneous freezing.

As you can see, in the question of whether it is possible to kill bedbugs with frost, there are many pitfalls. Yet their abilities are not limitless. What do scientists know about how long bugs live in the cold, and what degree below zero is fatal for them?

How many bugs live in the cold

Let's make a reservation right away that there are currently too few scientific studies on this problem to declare accurate data with confidence.

It is all the more interesting to learn about the results of a study conducted in 2013 at the University of Minnesota, published in the publication of the American Entomological Society.

It is, of course, very cold! But bedbugs can die at less critical temperatures if they are frozen long enough. Researchers placed insects by age group in freezers at different temperatures, and removed them at regular intervals. The purpose of the experiment was to study the ratio of bed bugs to die in frost, depending on the indicators of the thermometer and chronometer.

It turned out that among all age stages, except for eggs, there were no significant differences in survival rates. In addition, the results were not affected by the fact whether the bug was hungry or full.

The authors of the study recorded that 100% death of bed bugs at a temperature of -16 ° C occurs no earlier than after 80 hours. To know for sure whether the bugs will die in 15-degree frost, you need to keep them there for at least 3.5 days. At -20˚С - 48 hours. It is noteworthy that the eggs retain their viability when exposed to temperatures below -25˚С for a short time.

Bed bugs and frost: is it worth fighting in this way

Obviously, this method of fighting has its pros and cons. A clear advantage is that toxic drugs are not used, which means it is harmless to health and the environment.

Also, unlike pesticides, frost treatment does not develop resistance in insects. This is especially true for those countries where it is forbidden to use organophosphorus compounds in the fight against insects. Some professional disinfection services in the west use special equipment that generates ice microparticles from carbon dioxide.

But even these companies admit that the use of freezing gives results only in combination with chemical control agents.

The effectiveness of frost treatment is very limited, mainly due to the fact that it has no residual effect. A frost generator can be used to treat all foci of infection found in an apartment, but it is almost impossible to find and destroy every insect, and even more so eggs.

However, some small items, such as books or toys, can be placed in the freezer if contamination is suspected. Considering that the temperature in household freezers is from -15˚C to -20˚C, they must be kept for 3-4 days.

As for gadgets and other electrical appliances, you should be careful, as not all of them are designed for exposure to low temperatures and can break.

If, nevertheless, you decide to freeze electronic devices, be sure to place them in a tightly closed plastic bag to prevent condensation. After removing the device, do not turn on the device until it naturally warms up to room temperature.

Does it make sense to pull out a sofa and other large furniture outside in winter? Here again, the data obtained by scientists from Minnesota will come in handy. It is necessary to take into account whether the air temperature is low enough, whether there are significant changes during the day, and calculate from the diagram how much your furniture needs to be kept in such frost.

But there are important nuances here. Keep in mind that in those folds and crevices in which insects are hiding, the temperature may never drop to street level within the specified time frame. At the same time, it is unlikely that it will be possible to visually determine in what state bed bugs are in the cold - they fall asleep or die. Whether it is worth applying this measure, given the costs and uncertainties, needs to be determined on the basis of the circumstances.

In winter, bugs bite just like any other. However, in cold weather, it is unlikely that bugs will crawl from neighbors through a window or balcony. Insects can move from apartment to apartment through ventilation, through sockets and risers, so you should be on your guard.

And the last thing: it is clearly not worth trying to remove bedbugs in the house, turning off the heating in winter and opening wide all the doors and windows. Even if you manage to cool the house down to 20 degrees below zero and keep it in this state for several days, there is still no 100% guarantee of success. After all, bedbugs will look for their chance in the most protected secluded places from the cold.

But whether the house will be suitable for housing after such a procedure is a big question.

For effective destruction of insects, it is necessary to find out at what temperature the bugs die. Mattresses, carpets and baseboards are their main habitats. In any case, using any method, and taking into account the temperature at which bedbugs die, you will need to try hard to eliminate them.

Ways to eliminate bedbugs using high temperatures

When killing bedbugs with heat, you must be very careful so that high temperatures or steam do not harm the health of others, things, and the room.

Bed bugs die when their body temperature reaches 45 ° C. At home, this can be achieved with hot water, dry heat and steam.

All things that are subject to washing, including bed linen, and woven furniture coverings are loaded into the washing machine at a temperature of more than 50 degrees and washed for at least 30 minutes. There are items that cannot be washed at these temperatures, as they can deteriorate. In this case, they are folded into hermetically sealed plastic bags and sent to a clothes dryer, setting a temperature mode of 70 degrees.

Upholstered furniture and other interior items affected by bedbugs are exposed to steam using a steam cleaner. Each fold in the furniture must be carefully processed. In this case, the bugs will have nowhere to go and they will die.

Professional approach

One of the most effective methods for eliminating bedbugs is the use of an integrated room heating system. Industrial heaters in its composition heat the air inside the entire space to a temperature of 49 to 57 degrees Celsius.

Low temperatures help

Finding contaminated items in the freezer can kill bedbugs if certain conditions are met:

• in the freezer, the temperature must be maintained at (or lower) minus 18 ° C;
• this process will take a long time (at this temperature regime, at least 4 days);
• best of all items that need to be treated for bedbugs, place in bags and freeze.

The time can be reduced to 48 hours if the average temperature remains below -20 ° C. The lower the temperature, the less time it will take to kill bed bugs. The bags will help prevent bedbugs from spreading through the freezer. The bags will also protect items from changes in condensation or moisture damage.

Most dry household items can be frozen, including:

• textiles (bedding), which are not intended for washing at high temperatures;
• modern (non-antique) books;
• shoes;
• toys.

Some things require extra care when trying to freeze them. These are items that can be damaged if condensation occurs. Also, these are products that have high moisture or liquid inside.

However, even in very cold winters, it will not be enough to simply open the windows in the house.

However, it will still not be possible to achieve sufficiently cold conditions. Sunlight, humidity, and temperature fluctuations during the day increase the risk that bed bugs will survive. This method will also damage wallpaper, pipes, interior items.

On a frosty winter day, you can put things outside. If the temperature remains at minus 18 degrees Celsius, you will need to wait from two to four days. If the temperature reaches minus 7 degrees Celsius, you will need to wait about a week. For this purpose, you can also use a carbon dioxide fire extinguisher (-66 ° C) or liquid nitrogen (about -200 ° C). These methods will help kill insects instantly.

Steam and dry cleaning

When using steam against bedbugs, the process will take a long time. The steam temperature should be between 71 and 82 degrees Celsius. By applying heat evenly throughout the carpet, for example, it is possible to kill bedbugs wherever they are hiding, which is almost never achieved thanks to chemical types of pest control.

Steam is another form of heat that causes bed bugs, their larvae and eggs to die. Steam treatment is no more time consuming than other methods. This option works best for:

• blankets, sheets;
• curtains;
• pillows.

Heat in the form of steam can also be used to clean:

• carpets;
• places behind the plinth;
• upholstery of upholstered furniture, especially if it has a lot of seams, complex (in its cut) details.

Dry cleaning clothes at a temperature of 71 degrees Celsius will also help. Textile expert reports indicate that most dry-cleaned garments (e.g. cotton, wool, silk, linen, rayon, nylon) will not be damaged if placed in a clothes dryer. At the same time, things must be dry. Hot dryers and portable heat chambers can be used to kill bed bugs in infested household items.

Sometimes even in the apartment, where they regularly clean and maintain hygiene, insects start. The reasons can be the following factors:

• Unclean neighbors. Bedbugs have a flat body, until they pump blood, they can use tiny gaps and freely move from one apartment to another. Insects move not only on horizontal surfaces, but also on vertical ones. Therefore, ventilation shafts are also routes of movement for them.
• Dogs and cats... Animal blood is not suitable for bedbugs. But they are very fond of using them as transport. One female, caught in an apartment on a dog, can become a breeding source for an entire colony.
• Travel and travel. Bedbugs are often brought in suitcases from business trips when people stay in budget hotels. To prevent this from happening, it is recommended to choose more decent hotels, or hand over all things, including bags, to the dry cleaner.
• Used furniture... Buying furniture off-hand can be fraught with risks. You cannot be sure that bedbugs have not chosen a sofa or chair. Therefore, it is better to purchase new furniture, where the appearance of insects is, in principle, impossible, or to take preventive measures, which are described below.

Features of the bug body

To understand at what temperature the bug dies, you should familiarize yourself with its vital functions. From the time of appearance of the larva to the sexually mature individual, an average of one month passes. But this requires a temperature of about 25 degrees. An insect has a life cycle of a year.

However, if the temperature in the room drops to 15 degrees, then sexually mature individuals fall into suspended animation and can hold out for about 18 months.

Critical indicators

Too high and extremely low degrees are destructive for most insects. It should be remembered at what temperature the bugs die:

Such conditions can be allowed only in winter conditions, and the low temperatures are not always kept for the required time.

Steam use

When you find out at what temperature the bugs die, you can use the knowledge to destroy them, without the use of chemicals. Freezing can be used if conditions permit, or exposure to high temperatures.

However, even experts admit that killing insects is a challenge. If you do not strictly follow the recommendations, they may appear again. But, knowing at what temperature the bug dies, you can completely remove them.

1. Using a professional steam generator. A similar device is often used by special disinfection services. The method has an undeniable plus. You can treat a wide surface at once, while the method is safe for humans. Hot steam completely destroys not only adults, but their larvae.
2. You can use a thermal gun. A similar thing applies when installing a stretch ceiling. With its help, you can warm up the air to 60 degrees. If the exposure time is at least 30 minutes, then the complete death of insects is guaranteed.

At what washing temperature do bed bugs die?

When bed bugs appear, it is important not only to get rid of the furniture and mattress. The laundry can also contain larvae. It is important to know at what temperature bed bugs die and set the required mode for washing. Processing will be effective if the regulator shows at least 90 degrees.

In this case, ironing should not be neglected. Using the maximum values, it is necessary to iron the laundry from both sides.

Advice. To remove bugs from furniture cracks and from under the baseboards, pour boiling water in a stream.

Pros of using steam

The method is safe for humans. This method uses only clean water and a steam generator. Processing does not require special skills, you can handle it without the involvement of special services.

The use of steam is suitable for killing bedbugs on bed linen and clothing. But the use of chemicals can harm tissue fibers and cause allergic reactions.

However, the method also has negative aspects. It will not work to process books with its help. In addition, electrical appliances can also be damaged.

Having found out at what low temperature the bugs die, you can take advantage of the situation. If the weather is appropriate outside (below 15 degrees Celsius), then you can open the windows and leave the apartment for three days. If you are lucky with the weather, and the thermometer will show 20 degrees below zero, then a day will be enough for complete destruction.

The greatest effect is given by the removal of furniture to the street. This is especially true for sofas, beds and dressers. In any case, it is better to get rid of all the furniture that you do not mind.

Advice. If you managed to find a nest of bedbugs and the weather is warm outside, it is better to put it in a bag and freeze it in the refrigerator. This measure will help to get rid of insect reproduction and their spread on pet hair.

Disadvantages of freezing

• I have to leave the apartment for several days and leave the windows wide open. Not everyone can afford this method. But for non-residential premises, the method is optimal.
• If wallpaper is glued in the house, then they can move away due to low temperatures. Other finishes may also suffer.
• The heating system may become unusable. In the worst case scenario, heating radiators burst.

To avoid such problems, only furniture can be taken out into the cold. Slots and ventilation ducts must be treated with insecticides.

Safety precautions when dealing with bedbugs

The use of low and high temperatures allows you to effectively, quickly and safely remove bedbugs from the apartment. But it is important to observe safety precautions:

• Hot steam can cause severe burns; therefore, the steam generator must not be directed at yourself, other people or animals.
• Some items cannot withstand high temperatures. Therefore, you cannot process lacquered furniture, wallpaper and fabrics that are afraid of hot steam.
• If the steam has a temperature of more than 70 degrees, then the plastic surfaces are deformed.
• The steam generator can be adjusted to the desired humidity. High rates are not needed, the bugs will die at a lower one. But furniture can deteriorate from exposure to high humidity.
• It is necessary to freeze the apartment when the heating system and sewerage system are turned off.

Using professional equipment

Specialized services use bulky but powerful heat generators. They quickly raise the air temperature to 65 degrees. In such conditions, the bugs die, even if there is no direct impact on the nest.

Such units are expensive and bulky. They are used only by professionals, but the achieved effect is 100%. Therefore, if there is no possibility or desire to conduct an independent fight with intruders, it is recommended to call the appropriate service.

Professionals work under a service agreement. The cost of processing depends on the area to be cultivated and the method of control. In most cases, a steam generator is used and subsequent treatment of hard-to-reach areas with aerosols. The tools used are safe and the whole treatment will take less time than wrestling yourself.

Finally

Information about the temperature at which the eggs of bedbugs die, and sexually mature individuals helps to do without the use of insecticides. Bedbugs are very tenacious, but there are extreme indicators that even they cannot withstand. Therefore, if conditions allow, sofas and armchairs can be taken out into the cold.

A different situation is possible. In the heat of summer, the interior of the car gets very hot. Therefore, clothes and linen can be placed there and the machine can be left in direct sunlight. However, to prevent infection with car seat bugs, the interior is treated with disinfectants after the procedure.

Bed bugs leave bites on the body. They are especially dangerous for children. Therefore, if you find them, you should immediately get rid of them.

A decrease or increase in temperature regimes leads to the death of adults, that is, adults, and is the reason for the suspension of the development of eggs, the larvae inside which fall into a state of suspended animation.

Bedbugs feel quite comfortable at temperatures from twenty to thirty degrees, higher or lower rates can force them to go in search of another home.

So, how to deal with bedbugs by changing temperature readings - let's talk about this further.

At what temperature do bedbugs and their eggs die?

Environmental conditions have a direct impact on the life span of bedbugs, as well as the possibility of their existence in general.

If the conditions correspond to ideal, that is, the temperature indicators do not exceed values ​​of twenty-five degrees and do not fall below fifteen, the insect can quite comfortably exist for up to a year and three months.

At low rates, which do not exceed fifteen degrees, adults, that is, adults, fall into a state of suspended animation, the development of larvae and eggs is suspended.

The easiest way is to leave windows and doors open, turn off all heat sources, and then leave the room for at least a day.

However, this method has some drawbacks, namely, for the complete destruction of insects, the temperature in the room should not exceed minus twenty degrees, and remain at the specified mark throughout the day.

That is, there is a risk of damage to the heating pipes, there is a need to remove pets and indoor plants from the room.

High temperature is no less destructive for bedbugs. The death of insects occurs after a few minutes if the room temperature remains above fifty degrees.

When processing housing through the use of devices that maintain a high temperature, indoor plants, objects, things that may be damaged should be removed from the room.

At the same time, you should not stay in the house, as this can cause heatstroke.

At what temperature do eggs and larvae of bedbugs die?

Bedbugs and their larvae have a fairly high resistance to negative external factors, which include temperature, but with a constant or short-term decrease or increase in indicators to certain levels, they quickly die.

For example, adults can be in a state of suspended animation, that is, maintain the ability to live for a long period of time, if the temperature does not drop below seventeen degrees.

If the temperature does not exceed thirty-five degrees, bugs can exist, as under more favorable conditions, but their life expectancy is significantly reduced.

If for adult bedbugs the temperature, the indicators of which are optimal, is a factor necessary for the continuation of vital activity, then the larvae and eggs can remain viable for a long period of time even against the background of the most unfavorable conditions.

It is for this reason that the processing of the premises is recommended not to be carried out independently, but by contacting representatives of the relevant services.

If a method was chosen that implies self-processing, the procedure should be carried out several times at regular intervals.

Washing temperature for bedbug control

The easiest way to get rid of bedbugs is to wash the laundry well with a typewriter in very hot water, and then thoroughly dry and iron it.

So, at what temperature should you wash bed bugs?

It should be noted that the above methods, that is, washing, ironing things at a high temperature in order to destroy adult bedbugs, their eggs, are not global.

Temperature methods of dealing with bedbugs

So, the above were considered the most effective ways by which you can get rid of bed bugs.

The best method is to use a bug steam generator, this device will destroy colonies in the most secluded corners.

However, one should not forget that the methods of destroying bedbugs using high temperatures can damage the floor or other coatings, respectively, it is important to use them with special care.

How to deal with bedbugs

(1 estimates, average: 5,00 out of 5)

Bedbugs are neighbors that you need to get rid of right away.

Bedbugs are unpleasant and even dangerous neighbors in the apartment. You need to try to get rid of them as quickly as possible in order to prevent reproduction. To do this quickly and with a guarantee of the result, it is imperative to know what the larvae and bedbugs are most afraid of in the world, using the most effective means to combat them.

It should be noted right away that it will not be easy to destroy bedbugs. Any mistakes in the process will lead to the fact that the family of bedbugs not only does not suffer, but also increases in number. It should also be borne in mind that insects develop addiction to constantly used chemicals, which cease to have the desired effect on them over time. Therefore, the problem should be solved radically, with maximum responsibility.

What remedies are used against bedbugs?

• chemical agents;
• aerosols against bedbugs;
• bed bug fluids;
• powder products.

Any of these products can be purchased at a specialty store. Especially seriously it is worth taking the funds that include karbofos. The only point: products with karbofos should be used strictly following the instructions!

Home bugs: exterminate wisely!

When using chemicals against bedbugs, it is best to enlist the help of specialists. They know perfectly well what kind of preparations are suitable for disinfection in one case or another, they have experience in exterminating bedbugs in any conditions and have special equipment for this.

If, nevertheless, you decide to carry out disinfection without the help of specialists, then be sure to prepare for the operation with all responsibility, buy gloves and a protective mask. You will also need to use a spray bottle to kill bed bugs. When processing a room, it is important to follow certain rules:

• carefully pack the dishes with sealed foil so that the drugs do not get into the body of households after processing;
• ask all household members to leave the room during disinfection;
• remove children's toys, clothes and everything related to children away, after carefully examining them for the presence of bedbug eggs and larvae.

Removing bedbugs with folk remedies

If you are distrustful of "chemistry" of any kind, then you can try to poison the bugs with the help of folk remedies, for example, with the help of light or frost. Boiling water or steam, a solution of turpentine or kerosene, vinegar, transformer oil and wormwood will also be effective.

Each of these tools is effective in its own way, so you can choose any of them. The easiest way is to expose bedbugs and larvae to extreme temperatures. In summer, for example, when the temperature is over 40-45 degrees Celsius, contaminated items and furniture can be taken outside. Under such conditions, insects die within a few hours. Inevitable death awaits bedbugs and under the influence of frost. Large things and furniture can be taken out on the balcony or outside in the yard when the frost is below 20 degrees Celsius. While waiting for frost, small things can be hidden in the freezer. There the bugs will die within a few hours.

Alternatively, you can use an iron or steam cleaner. It will be possible to iron the bed with an iron, in the folds of which there may be eggs, larvae and even adult bugs.

What grass to use to fight bed bugs?

The most effective herb in the fight against insects is wormwood. Its smell helps to destroy not only bedbugs, but also fleas. It is recommended to use wormwood in conjunction with other means, for greater effect, both with folk and chemical. You can pick wormwood yourself, or you can buy it already dried at any of the pharmacies.

The way to use it is very simple: grass twigs are laid out throughout the apartment, especially in those places where there may be accumulations of little bloodsuckers: under the bed, under the mattress, behind the baseboards, in books, in the closet, and so on.

Before you lay out the wormwood around the apartment, you will need to carry out a general cleaning in the house by boiling and ironing all the bed linen and things. Attention! Be aware that fleas can live on your pets, as well as on their bedding. When laying out the wormwood, do not forget to put a few twigs under the cat's or dog's mattress.

Ultraviolet in the fight against bed vampires

It is not for nothing that insects live in the darkest corners of the apartment. The bright light, like real vampires, kills them. In the absence of light, bugs feel better and see perfectly. As another option for dealing with bed bugs, you can use a quartz lamp.

Its light is dangerous not only for insects, but also for people, therefore, the lamp should be used carefully. The bug has 2 eyes, each of which has the photosensitivity of 6 scorpion eyes, it has excellent vision, but the insect is deprived of the ability to see images in colored. The bug sees everything in gray, except for warmth - he sees it in red, so he so clearly finds the warmest places in the apartment.

What smells the bug is afraid of

The perception of odors in bedbugs is carried out with the help of sensilla, which are located on peculiar antennas. Outwardly, sensilla resembles hairs. At their base are receptors that are responsible for the perception of odors by neurons.

Taking these factors into account, scientists conducted a number of studies and concluded that insects' reaction to smell is related to the concentration of volatile substances. Undiluted extracts repel bloodsuckers, while strongly diluted ones, on the contrary, attract. It is with this that the bugs bite some people more than others.

For a long time, people have tried to scare off bedbugs with the smell of grated calamus and tansy. The scent of bedbugs does not kill, insects just try to stay away from it. Bedbugs do not tolerate ordinary chamomile. You can buy it dried at the pharmacy and scatter it on the floor. Scaring off bedbugs with smells, you can enhance the effect with a saline solution, which will need to wash the floors in the apartment and fill the cracks where insects can live.

Unconventional methods of dealing with bedbugs (grandfather's)

In the fight against bedbugs, all methods are good, which means that you can try not only the traditional methods, but also the so-called old-fashioned ones, which were used by our ancestors, when there were no ultraviolet lamps and "chemistry". The real effect of such means is not high, but by combining these methods with more modern methods of struggle, you can achieve success.

What temperature is needed for the death of bugs and their larvae?

To get rid of them, you need to use chemicals or temperature conditions. Here you will find the answer to the question of how to get rid of bedbugs in an apartment.

This article will tell you in detail how you can destroy all bed bugs using the temperature regime.

The harm of bedbugs

A healthy person suffers less from a bug bite than someone who is prone to allergies. When bitten, these insects inject an allergen, which causes the skin to redden and itch. The bite sites soon swell and cause an allergic reaction.

Signs of allergies are:

• heat;
• headache;
• dry cough;
• nausea;
• dizziness;
• dyspnea.

Therefore, allergy sufferers and infants may experience one or more of the above symptoms.

Bedbug damage can also cause unpleasant effects:

1. poor sleep or insomnia;
2. irritation of the nervous system;
3. weakness appears in the body;
4. distracted attention;
5. severe migraines;
6. there is aggression towards everything that happens;
7. asthma attacks.

Bed bugs can carry diseases such as:

• syphilis;
• hepatitis;
• tuberculosis;

Bedbug bites fall into three categories:

• Easy degree. The affected areas are washed with cold water or rubbed with alcohol. And also helps aloe juice.
• Average degree. With bedbug bites on a person, folk remedies that can be bought at pharmacies help. These include:
  • Fenistil-gel;
  • Bepanten;
  • "Star".
• Severe degree. If the reaction to bites worsens, Diazolin or Elcet should be taken orally.

To improve the nervous system after bites, you need to drink medicinal herbs that are added to tea.

These include:

• chamomile;
• thyme;
• mint;
• melissa.

Dependence of the life cycle of a bug on climate

Bed bugs do not fly, but when they accumulate in large numbers, they produce a specific smell.

How long bed bugs live depends on the climate.

Usually, bed bugs go through their life cycle within a month:

1. It all starts with the laying of eggs. The female can lay 5 eggs per day.
2. Every 5 days, bugs go through a certain stage of development, while growing from 1.5 mm to 5 centimeters in length.
3. The average life span of a bug is 10-14 weeks, depending on habitat conditions.
4. Bedbugs can live for a month without food.
5. At low temperatures, the insect can go into suspended animation and survive for another year.
6. When the temperature regime is restored, the pest will continue its development and life cycle.

What are the causes of bedbugs?

Reasons for the appearance of bedbugs:

Bedbugs can live in such places:

• in mattresses, blankets and pillows;
• cracked walls and floors;
• in upholstered furniture;
• in peeling wallpaper;
• in bedside rugs, etc.

How to avoid bedbugs?

To avoid the appearance of these pests, the following rules must be observed:

Sharp temperature changes in the room negatively affect the life of bedbugs. Insects easily tolerate temperatures of minus 10 degrees Celsius. They just hibernate.

To kill them with frost costs 4 days to maintain the temperature in the room minus 15-20 degrees Celsius. However, if the insect has laid eggs, such frost is unable to destroy them. You will need to lower the temperature below 20 degrees below zero for several hours in order to completely destroy the ovipositor.

Unfortunately, when fighting domestic pests with cold, you can highlight such disadvantages as:

• With prolonged exposure to cold, a modern heating system can deteriorate. It will have to be covered with non-flammable materials, which can be time-consuming.
• Frost can damage equipment:
  • a computer;
  • television;
  • tape recorder, etc.
• Indoor flowers will perish.

Bedbug eggs are covered with a special shell that protects against frost and various chemicals. Therefore, it is worth transferring all the equipment, plants to another room and cooling the room for a couple of hours. For prevention purposes, you need to do this twice a month.

From all of the above, it follows that for the destruction of insects it would be best to use high temperatures in order to permanently get rid of blood-sucking pests.

What heat can the bugs not tolerate?

You can also fight bedbugs at high temperatures. It has been found that insects die at 90 degrees Celsius.

If bed bugs have been spotted in bedding or couches, steam generators or steam irons can be used. It is worth spending just one hour working on the folds, bends of furniture, but the result will be excellent.

Using such a tool, you need to follow certain rules:

• do not point the steam generator at a person;
• do not use the device near power outlets;
• do not direct it towards wallpaper or varnished materials, which may be damaged;
• plastic covers may deform when exposed to high temperatures from the device.

Optimum washing temperature for bed bugs

You can destroy bedbugs when washing in this way:

1. When washing by hand, the linen is placed in boiling water for half an hour, while covering the basin with a film. Then use the powder for washing.
2. In the washing machine, the water temperature should not be lower than 60 degrees Celsius. The washing process at high temperature should be at least one hour.

After washing, the laundry is dried and then ironed with a steam iron. All creases should be evaporated.

Facts, speculations - at what temperature do bugs and larvae die

At what temperature do bedbugs and their larvae die?

• +14 degrees - the female stops laying eggs;
• +10 degrees - the laid eggs stop developing, the embryo freezes;
• +5 degrees - the whole generation falls into suspended animation.

It follows from this that traditional methods of combating airing and blowing boiled water over the infected area are ineffective.

Do bedbugs die when washing

Rules for hand washing

• Water is poured into a basin immediately after it boils.
• Immerse the laundry for 20 minutes, cover the basin with plastic wrap, oilcloth, or something else to keep the temperature high.
• Then you can add powder, carry out normal washing.

Machine wash rules

• The temperature should be at least 60 degrees.
• It is preferable to set the mode with 95 degrees.
• The duration of the procedure should be at least 1 hour.

After the clothes are dry, be sure to iron them with a steam iron. Pay special attention to seams, folds.

The temperature method is often used to kill bed bugs. It is based on the use of high and low temperatures. Moreover, you can use them only in winter.

Freezing

In ancient times, in order to destroy the "living creatures" in the house, in case of frost from -10 degrees, doors and windows were opened, and left for at least 2 hours. Under such conditions, not only adults, larvae of different generations die, but also eggs. Today, this method is considered not the most effective for several reasons:

• Low temperatures are poorly tolerated by a modern heating system. After prolonged freezing, you can remain unheated. It is recommended to wrap up batteries, a boiler, which takes a lot of time, energy, materials.
• Low temperatures can damage household appliances - TV, computer, laptop, stereo, etc. They will also have to be wrapped up or taken out to another room.
• Indoor plants will not tolerate freezing.
• In the course of numerous studies, it has been established that frost of about 20 degrees Celsius is a deadly temperature for adults. Moreover, the impact should be at least 1 day. To create such conditions indoors, the temperature outside the window should be about 30 degrees below zero. Only then can the desired result be expected.
• In addition, the natural instinct for self-preservation should be taken into account. At the sight of danger, bedbugs will hide in different crevices, where the frost cannot reach them. When all this stops, insects will crawl out of the shelter.

Warming up

Thus, applying such methods of dealing with bedbugs is currently not the best option.

Sanitary and Epidemiological Services use two methods - hot, cold mist treatment. The effect of temperatures is combined with insecticidal agents. The methods give 100% results, are considered the most effective.

Hot mist treatment

Air is pumped into special equipment - a fog generator. They also serve insecticidal
substance. In the process of work, the poison comes out along with the hot air in the form of tiny droplets. A cloud of fog is created in the room, which lasts for 10 hours. During this time, hot particles of the insecticidal agent penetrate into all the cracks of the room. When cooled, they settle on the surface, thereby creating a layer of poison. Professional processing gives 100% result. However, it is recommended to enter the premises in a day. Otherwise, you can get poisoned yourself. Hot air slightly increases the humidity in the room, which is one of the advantages of the method.

Cold fog treatment

The principle of operation is similar. Only hot air comes out, but cold air. The molecules of the insecticidal agent are much larger, so they settle faster. The fog cloud lasts only 4 hours. During this time, the poison spreads throughout the room. The main task is performed by an insecticide. It is he who gradually poisons the entire generation of bedbugs. This method significantly increases the humidity in the room, household appliances may suffer. Before processing, you need to worry about its safety.

The method of generating steam differs from the usual disinfestation with an insecticidal agent in the ability to evenly distribute the poison over all surfaces. This is almost impossible when using a spray. It is necessary to follow all the recommendations of specialists, not to enter the room ahead of time. In developed countries, after disinsection, an apartment is not allowed to enter it for about a week. Which is very correct from a security point of view.

Dangerous temperature for bedbugs - summing up

Bed bugs are highly resistant to high, low temperatures.

The most correct method of dealing with bed bugs is a combined one. When combined with steam, frost and insecticides. That is why professional disinsection of SES always gives a better result than an independent fight using the same poisonous means. Bedding is cleaned before pest control. They are washed at a high temperature, boiled, ironed with steam.

What are bedbugs afraid of? What causes bedbugs to die.

What are bed bugs afraid of?

Bed bugs show a high level of resistance to various adverse circumstances in their environment. Evolution has endowed them with various abilities that help them in a constant struggle for survival. However, there are factors that bedbugs are afraid of and try to avoid.

1. Bedbugs have a strong sense of smell, they are able to sense the food source in the building even several floors away. Therefore, bugs avoid those rooms where any odors that are not natural for them are formed. Smells of perfume, bleach, tobacco, cigarette smoke, burning will interfere with bugs to navigate in space and give them discomfort. Insects will try to leave such premises.

2. Bedbugs do not tolerate loud noise. If loud music is constantly playing in the apartment or repairs are being carried out using instruments that create strong sounds, then most likely the bugs will leave this place. That is why bugs do not start in production facilities.

3. Bed bugs do not get along well in an environment where there is a high percentage of humidity. In order for the bugs to leave the apartment, you need to create an air humidity of at least 75-80%. This indicator can be achieved by using special room humidifiers. The fact is that at high humidity in bed bugs, a harmful fungus forms on their chitinous cover, which gives these insects severe inconvenience and can cause the death of bugs.

4. Bed bugs cannot stand common table salt. Places in the room treated with a highly saline solution will not be infested with bed bugs. The disadvantage of this protection is white salt streaks and stains after such treatment.

5. Also bugs will not be able to survive at temperatures above 45 degrees. If you manage to heat the room to this temperature and keep it in this state for at least 3 hours, then the insects will die completely.
