What Temperature Can Fleas Not Survive in?

It’s important to understand that high heat can kill fleas. They can’t survive temperatures over 95 degrees, and they can’t survive heat for more than 40 hours in a month. The best way to kill fleas is to wash their bedding and clothing in high temperatures for at least 10 minutes. Use a detergent diluted with water and wash at the highest temperature possible.

However, there are some areas where fleas thrive all year round. In Florida, for example, the winter months are a hot spot for fleas, with the weather remaining relatively warm. Usually, a temperature of 95 degrees Fahrenheit and a relative humidity of 75% kills fleas within two days.

Fleas prefer temperatures between 75 degrees and 50 degrees. Below that, they will cocoon, and they won’t survive in a freezing temperature. In freezing temperatures, fleas can only survive if there are warm animals nearby. This is why fleas are most vulnerable during the winter season.

While the winter months can kill fleas, it doesn’t kill them completely. Even though they can’t survive cold temperatures, flea eggs can. In addition, fleas are less active during the winter months. If you want to protect your home from fleas, you should consider getting a flea treatment for your pet.
