What Temperature Kills Roaches

Temperatures between 15 and Zero degrees Fahrenheit will kill a cockroach, and they cannot breed at temperatures below 40 degrees. So, once temperatures start to drop, roaches look for a warm place to hide. A cockroach’s favorite place to spend the winter is inside your home.

Can roaches be killed by heat?

Because cockroaches cannot survive temperatures above 115° F to 120° F, it is possible to use heat to eradicate cockroaches from restaurants and food service establishments. After heat- sensitive equipment is removed from the building, the temperature is increased to about 140-150° F for five to six hours.

Do roaches die in the winter?

Winters pose risks to cockroaches, which are naturally tropical creatures; they will often die when exposed to temperatures less than 15 degrees Fahrenheit. However, cockroaches can find plenty of ways to avoid that exposure and survive the cold months.
