German cockroaches can die if left to heat below 45°F for longer than 10 hours. They also die if they are left to heat below 14 degrees F. This is because they cannot withstand extreme temperatures.
After being exposed to temperatures as high as 50 degrees, cockroaches cannot regulate their body temperature because they are cold-blooded. As a result, they die when exposed to temperatures they don't like.
Different species of cockroaches have different survival rates. They can survive at the right temperature. However, they will die if exposed to too much heat or too little cold. They can be frozen or heated, but they will not survive. Tom's Pest Control Canberra can help you if you have severe infestations of cockroaches in your home or office.
