In the modern world, no one is immune from unwanted proximity to blood-sucking parasites in their homes and apartments. If your sleep has worsened, you periodically feel that something strange is crawling across your body, and itchy rashes appear on your skin, then we can confidently assume that you have uninvited guests in your apartment - bedbugs.

When these insects enter your home, they need to be dealt with. You may not notice their presence for a long time, but sooner or later they will make themselves known.

Controlling bed bugs requires a serious approach. They can be destroyed using chemicals or folk remedies, but the main thing is to achieve results.

There is also a method that allows you to get rid of bed bugs - this is heat treatment, in which the insects are destroyed by exposure to high temperatures.

At what temperature do bedbugs die?

First of all, it should be noted that bedbugs are living creatures and require a certain temperature environment to survive. If the ambient temperature does not meet certain criteria, bedbugs, their larvae and eggs die. In other words, if temperatures are too low or too high, bedbugs cannot survive.

Ideal living conditions for bedbugs are set at a temperature of 25 to 30 degrees Celsius. However, bedbugs can survive at temperatures of plus 10 degrees. At temperatures below -35 degrees, bedbugs die, falling into a state comparable to torpor. The larvae also change their behavior and stop emerging from the eggs.

If low temperatures are maintained indoors for a long time, the bedbug population will die. Frost is fatal to these insects. At negative temperatures, bedbugs die.

The same applies to high temperatures. When the air warms up above 45 degrees Celsius, insects are doomed. The higher the room temperature, the faster you can get rid of bedbugs.

This property of insects was noticed by people, and they began to use temperature effects in pest control. For example, pieces of furniture infested with bedbugs are taken out into severe frost, since the parasites cannot tolerate such temperature changes.

Considering that bedbugs die at high temperatures, contaminated clothing is washed in hot water or boiled. A steam generator is used to treat the apartment. Sometimes after such events the bedbugs die.

Thus, at extremely low and high temperatures, bedbugs are unable to survive. You can get rid of them by using cold and hot steam. Clothes can be cleaned by washing - just put the items in the machine and run it on the maximum temperature setting.

Can bedbugs survive such measures?

Bedbugs are highly resistant, and the use of high or low temperatures to combat them is not always effective. Even if you manage to get rid of the pests that have taken over the furniture, bedbug nests may remain in the apartment, and finding them and treating them with a steam generator or extreme cold can be challenging.

In addition, bedbugs are able to survive if the temperature returns to normal after a sudden change. If the insect is exposed to dangerous temperatures (high or low) for a short period of time, bed bugs may survive.

Scientific research confirms that larvae and adult bedbugs can adapt to difficult survival conditions. At temperatures from +25 to +30 degrees Celsius, they can live without food for up to one and a half years. This is surprising, considering that even at 10 degrees Celsius, bedbugs do not die, and to destroy them it is necessary to keep the room temperature at -17 degrees Celsius for XNUMX hours.

Heat, unlike frost, has a faster effect on bed bugs. When exposed to temperatures of 45 degrees, they can only survive for about 45 minutes.

Some enthusiasts conducted an experiment to study the effects of temperature on bedbugs, and the results obtained were quite interesting.

Processes in the body of bedbugs

As mentioned earlier, the metabolism of bedbugs is directly dependent on temperature, and this affects their development. Let's look at how bedbugs react to different temperature conditions:

  1. At air temperatures above 35 degrees Celsius, the life expectancy of bedbugs is reduced by two months. (Bedbugs typically live for about 12 months.)
  2. At a temperature of 15 degrees Celsius, bedbugs and eggs do not die, but their development is practically stopped. Destruction of eggs is possible only at temperatures below -17 degrees.
  3. At temperatures around 25 degrees Celsius, the lifespan of bedbugs is approximately 15 months.

How temperature of +50 degrees affects bedbugs

Experimental studies were carried out by specialists who took four adult bedbugs and placed them in a small container, and then placed this container in a larger tank. When using a thermal gun, the temperature in the container was increased to +50 degrees Celsius. The results obtained were impressive.

When treated with air heated just five degrees higher, the bed bugs died in nine minutes. From this we can conclude that at higher temperatures the rate of death of insects increases.

However, the question of egg survival remains. If they remain untouched at high temperatures, then after a few days they may hatch into parasite larvae. After a week, new bedbugs will appear, which emphasizes the need to repeat the procedure to completely eliminate the problem.

The effects of cold temperatures on bedbugs

The destruction of parasites at high temperatures is more effective than when using low temperatures. Bed bugs have an amazing ability to survive in harsh winter conditions, be it natural environments or human structures.

Bedbugs typically live in rodent burrows in the wild. They choose caves and nests to live in, where they feed on the blood of bats and birds, and also lay eggs. These eggs hatch into larvae and the insect population increases.

However, living conditions in nature are not typical for those types of bedbugs that prefer to live in human dwellings. Bed bugs, in particular, have adapted to life in apartments and houses, maintaining the ability to withstand low temperatures.

When the room temperature drops, bedbugs enter a state that can be compared to suspended animation. Their life cycles slow down almost to a stop, and they simply wait for more favorable conditions for active life and reproduction.

Bedbugs, like parasites, have adapted to living on the human body for many centuries. Their ancestors also lived in human dwellings and faced low temperatures, which over time formed a kind of immunity in them. Thus, bedbugs turned out to be more resistant to low temperatures than to high ones.

How to kill bedbugs using high temperature

We have found that high temperatures effectively kill both bedbug eggs and the bedbugs themselves. There are proven methods of heating air that provide reliable results. To use these methods, you will need to purchase special equipment - a heat gun, costing about five thousand rubles.

It is worth noting that for a similar price you can order professional disinfestation from experienced specialists who will effectively treat your premises, clean furniture and destroy pests in accordance with the requirements of sanitary and epidemiological standards.

If you do decide to purchase a heat gun, you can use it repeatedly. Just turn on the gun and heat the air in the apartment to a temperature of +50 to +60 degrees Celsius, using a thermometer for control. Under such conditions, bedbugs will not be able to survive. It is recommended to carry out the treatment for an hour so that hot air and steam can penetrate into all corners of the room and treat your items and furniture.

Before starting warm air (steam) treatment, move all furniture away from the walls and, if possible, disassemble large items such as cabinets, tables, beds and sofas. This will help hot air penetrate the bedbug nests and thoroughly treat their habitats.

Other ways to kill bedbugs using high temperatures

There are several alternative methods of using extreme temperatures to control bedbugs. To treat items with steam, you can use a steam generator, which is effective for cleaning furniture, baseboards and cracks in walls. After such treatment, some bedbugs may have time to leave the treated area, but the rest will die.

However, using a steam generator on your own does not guarantee complete elimination of bedbugs due to the difficulty of detecting and treating their nests located in hard-to-reach places. Repeated treatments with a short time interval are necessary to completely destroy all insects.

Another method is to wash items at high temperatures. If you have returned home after a trip or business trip, where you may have been in conditions unfavorable for your home, it is recommended to wash things at a water temperature of at least +60 degrees.

At this temperature, the water will be lethal to any insects that may have entered your clothing, and boiling is not necessary to achieve the desired effect.

Safety rules when processing an apartment

Using high heat to kill bedbugs requires following safety precautions to avoid possible injury. Follow these guidelines:

  1. Keep all steam-producing devices at a safe distance from the items being processed. Avoid contact of unprotected areas of skin with hot steam.
  2. When handling with boiling water, use protective equipment such as gloves and hold the kettle with a cloth. Boiling water can cause burns.
  3. Study the material of the item being processed to avoid damage. Check this information online or on the label.
  4. When working in high temperatures, use special gloves to protect your skin. If you don't have them, you can use regular gloves. Also wear thick clothing.
  5. Please note that the steam cleaner covers a limited area, so the process may take longer.
  6. Remove dead bed bugs regularly to prevent damage to furniture or fabric.
