German cockroaches can die if left to heat at 45°F for longer than 10 hours. They may also die from the heat below 14°F.
After being exposed to temperatures as high as 50 degrees, cockroaches cannot regulate their body temperature. 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, too little cold, or both. They can be frozen or heated, but they will not survive. If you have severe pest infestations in your home or office, Tom’s Pest Control Brisbane can help.
