At what temperature do cockroaches die: the highest and lowest threshold
Many people believe that cockroaches are the most tenacious creatures on the planet. This myth is backed up by many stories circulating in the open spaces of the boarding school, which say that these insects have perfectly adapted to extreme conditions and are able to survive even after a nuclear explosion. In fact, cockroaches are just as vulnerable as many other insects, and even slight temperature fluctuations can kill them.

What temperature is considered comfortable for the life of cockroaches
Cockroaches prefer comfortable warmth. These mustachioed pests do not tolerate extreme cold or too hot weather very well. The most favorable conditions for these insects are considered to be room temperature, which usually ranges from +20 to +30 degrees Celsius. Even a slight deviation from these figures can affect the vital processes in their body.
What temperature is considered fatal for cockroaches
Cockroaches are very dependent on fluctuations in air temperature. If at +20 degrees they feel quite comfortable, then when the temperature drops by only 5 degrees, they become uncomfortable. To describe the effect of cold on cockroaches, several temperature intervals are distinguished:
At this temperature, cockroaches do not die immediately, but fall into a state of suspended animation. This allows insects to wait out adverse conditions and return to their usual lives immediately after warming comes.
Such a decrease in temperature can be dangerous for the viability of eggs and larvae, but most likely will not affect adults. Most adults tolerate such conditions without problems and, after raising the temperature to +20, come out of hibernation unharmed.
At this temperature, cockroaches will no longer be able to escape and will most likely die. The only caveat is that prolonged exposure to cold is necessary for death. It takes 10 to 30 minutes for all insects to die.
Air temperatures below -10 degrees Celsius almost immediately lead to the death of cockroaches at all stages of development.
It is worth noting that cockroaches are afraid not only of cold, but also of extreme heat. An increase in temperature above 35-50 degrees Celsius will lead to the death of insects after a few hours.
Methods of dealing with cockroaches with the help of cold
Cockroaches have been causing problems for mankind for many years and a variety of methods have been used to combat them. Knowing the weakness of these pests to low temperatures, people have found several ways to use it against them.
Destruction of cockroaches with the help of high temperature
As you know, high air temperature is no less dangerous for cockroaches than low, but, under natural conditions, heating the entire room to +40 degrees Celsius is simply unrealistic.
In this case, a special device is used to combat insects - a hot fog generator.
The hot mist generator is a device used by specialized cleaning companies. The principle of operation of this device is to spray water vapor, the temperature of which exceeds +60 degrees. For greater efficiency, not only water, but also insecticidal preparations are added to the tank of such a device.
Conclusion
Cockroaches, like other living creatures on the planet, have their weaknesses. These insects are very sensitive to temperature changes and, as it turned out, they tolerate cold snaps even worse than humans. But, cockroaches do have an ability that helps them survive in difficult conditions - this is their unpretentiousness in food. Thanks to this, the cockroach family will never remain hungry and will always find something to eat.
