Cockroach eggs can die in the cold when they are exposed to prolonged cold. The oothecea on the other hand can resist much colder temperatures. If you leave cockroach eggs outside at -18c you can expect them to die. This begs the question though whether grown cockroaches can survive the cold. Cockroaches are known as very resilient insects and can manage the most extreme circumstances with relative ease.

Cockroaches can die in the cold when they are exposed to extreme temperatures and prolonged cold. The ootheca or egg sack can resist much colder temperatures than the eggs alone. if they were to be exposed directly to the cold they would die instantly since they do not have a protective layer 2 defend themselves from the elements. The temperature that cockroach eggs outside or the oothecae can resist is minus 18 degrees Celsius. Cockroaches themselves are incredible at surviving where they can survive decapitated without a week and can survive 30 minutes away without any oxygen supply.
Cockroaches are acclimated to warm temperatures that have an adequate moisture level. Cockroaches can die from the heat. If the temperature reaches above 49c then you can expect the cockroach to live not more than a few days. The German cockroach can survive these temperatures for approximately 4 days. As the cold is concerned, cockroaches will not survive temperatures below 0c. Although this will be a slow death as well. You can expect the same duration for all cockroach species to die at these temperatures.
Cockroaches have a strong issue with warmer temperatures. However when a cockroach is exposed to extreme heat above at least 49 degrees celsius then you can expect the cockroach to die within a few days. The German cockroach for example can survive these temperatures for approximately 4 days on end. As for the cold, it’s concerned cockroaches will not survive temperatures below 0 degrees although this will be steady in gradual demise. the same can be expected for all kinds of cockroach species.
To fend against these extreme temperatures cockroaches, have a defence mechanism against it called diapause. Diapause can be compared to hibernation in mammals with the key difference being that the function is activated in extreme an adverse temperatures where the life of the cockroach is in danger. when diapause is activated the metabolism functioning gets dropped and slows down as well as other functions as well. this includes a slower heartbeat and slower breathing. diapause often occurs with insects whereas hibernation occurs with mammals.
There are preventive measures that people can integrate into their cleaning regime to get rid of cockroaches. Cockroaches are attracted to water and food. Once these two sources are cancelled out, there is no reason for cockroaches to come to places. By eliminating still water such as the water often left in the sink and the leftover that are often left inside, you should see fewer cockroaches. Most people think it is because of food and water but forget that warmth also plays a role in it which cannot be controlled by most people. And so, professional extermination is the best option to get rid of the roaches for good.
