How Cold Does It Have To Be To Kill Cockroaches?
Cockroaches are very sensitive to cold temperatures. As a result, they tend to look for areas of shelter to stay warm. Temperatures below fifteen degrees Fahrenheit will cause their metabolism to fail, and they will eventually die. Cold temperatures also cause the roaches to slow down their activity.
Cold temperatures can be dangerous for cockroaches, but they will survive if the temperature is a few degrees above freezing. Most cockroaches will die after half an hour at 0 degrees Fahrenheit or -17 degrees Celsius. That is way below the freezing point of most human homes.
If you are concerned about the cold temperatures, you can also turn on your heat. This will keep the roaches from entering your home. If your home is cold, the temperature will be too low for them to survive. It won’t kill them instantly, but it will make them more likely to move to a warmer area. Keeping the temperature in the low teens will help keep your house pest-free and healthy for your family.
While roaches are resilient to heat, temperatures below that can kill them. If you have a large infestation of cockroaches, it can be difficult to get rid of them. In this case, you might consider using diatomaceous earth. This natural stone powder is composed of crushed up shells and works by dehydrating bugs. But you need to replace the diatomaceous earth regularly to make it effective.
