At What Temperature Do Cockroaches Die?
Page Contents
Just like all other creatures or pests, cockroaches prefer certain conditions over others for a living, and can even die if the living conditions do not suit them.
While the mere sight of a cockroach can be disgusting and scary, they are pretty interesting creatures and do not have aggressive behavior, in general. A cockroach’s life is ruled by thirst, hunger, sex, and safety. So they usually enter our homes in search of food, water, mates, or shelter.
A Few Quick Facts about Cockroaches

- 30 out of these species of cockroaches are living close to or inside the human habitat
- 4 of these cockroach species are identified as pests.
- All species of cockroaches are tropical creatures and are quite resilient
- They have strong survival skills despite not having a brain
What Temperature Do Cockroaches Prefer?
Cockroaches move to the place where they find the temperature that they prefer and move towards the source of moisture. They prefer to live in a temperature ranging from 25 to 30 degrees Celsius.
And if the temperature in your room falls below 25 degrees, cockroaches are likely to move out of your room to a warmer place. These are cold-blooded creatures, so they dread the heat, and they prefer almost the same temperatures as we do. So while you’ll be thinking you’re adjusting the temperature for yourself, you might be inviting these insects to your place by giving them the right living conditions.
Cockroaches Are Heat-Seeking Insects
Almost all species of cockroaches prefer warm surroundings to live in. So they infest the interiors of homes such as kitchens or garages rather than the exteriors such as gardens. Their main breeding seasons are the warmer ones.
So if your home remains warm for a prolonged time, there are increased chances of a cockroach infestation. Also, since they usually come out at night, you can miss noticing an infestation, or it might be larger than you think. Cockroaches prefer humidity and heat, and they like to stay near a source of food, so they are likely to stay near your kitchen or bathroom areas.
Effects of Cold Weather on Cockroaches
Cockroaches are cold-blooded organisms, so they cannot regulate their internal temperatures. Although these creatures are quite adaptable, they cannot survive the temperature if it’s too cold, and it affects them very much.
Most species of cockroaches will die when placed in a place below 0 degrees Fahrenheit. Therefore, cockroaches, primarily American and Surinam cannot survive in gardens with low temperature.
However, Cockroaches respond psychologically to low temperatures. If you put them in a place and lower the temperature slowly, they might adapt to the falling temperature, and there are chances of their survival. But if they are subjected to low temperatures instantly, their mind won’t adjust to the cold and neither will their bodies, making their survival very unlikely.

What Do Cockroaches Do in the Winter?
Cockroaches dread winters, and when the temperature falls, they go into a hibernating state called diapause.
In cold weather, they stop all activities like breeding or growing. They might come to your house in search of warmth and make their nests near a food source.
What Do Cockroaches Do in the Summer?
Cockroaches are much more active in summers than in winters, and they tend to move a lot in the steamy season. Entomologists and pest control experts have said that heat can cause cockroaches to perform activities that they don’t perform often, such as flying.
According to a biology professor, cockroaches try to find more suitable conditions to live in when they are exposed to extreme heat. They try to find a cooler place to move to which can be a reason of infestation in your home.
An increase in temperature causes insects to use more energy. Their growth depends upon a nice temperature, and they remain more active when they move to a place with the right temperature.

Cockroaches Are Also Attracted to Moisture
You might’ve noticed that the cockroaches are multiplied or more active in the rainy season. This is because of their love for humidity. These insects prefer warmth and humidity. So if your air conditioner is dripping or has condensation, it can attract cockroaches to your place.
Being tropical creatures, most roaches not only prefer humidity but “need” humidity. They crave moisture, and dry living conditions can cause their health to deteriorate, and they might stop breeding too.
You can use this in your favor by keeping your house dry and clearing up any liquid spills. Making sure that your home is not humid can help make the cockroaches go away.
At What Temperature Do Cockroaches Die?
Being cold-blooded organisms, cockroaches cannot regulate their bodies’ internal temperatures. Therefore, they meet their death when exposed to temperatures that aren’t preferred by them.

“Cockroaches die if the temperature rises above or falls below their adaptability.”

German cockroaches die within 10 hours when exposed to a temperature below 45 degrees. They will die within an hour if exposed to a temperature below 14 degrees Fahrenheit as well.
They cannot tolerate much heat either. At a temperature of 50 degrees, only half of the cockroaches survived, when exposed for two weeks. These surviving insects could live for more than four days.
In summary, different species of cockroaches have different levels of survival. They can survive if they find the right temperature to live in. And they will die if the surroundings get too hot or too cold. “Heat them or freeze them”, both will make these insects die.
