What Temperature Kills Fleas?

You may be wondering what temperature kills fleas. Fleas do not thrive in freezing temperatures. However, fleas can survive in warmer temperatures if they find food. They are most active in the summer and fall when the temperature is about 75 degrees. So if you find a flea in your home, don’t wait until winter to treat it.

Fleas prefer warm and humid conditions. You should expect them to peak activity in the spring, summer, and fall. While they can survive in the winter months, they need warm environments to stay active and lay eggs. This is why you should treat your home against fleas in order to protect your home and your pet.

While heating the entire house may sound like an easy way to get rid of fleas, this is not very practical. While people have successfully killed fleas in their homes by heating them to 100 degrees for 48 hours, it would be inconvenient and expensive. The proper temperature for killing fleas is 95 degrees Fahrenheit.

If temperatures in your home drop below freezing, you should apply flea preventative to your pets. While fleas cannot survive in freezing temperatures, cold temperatures will kill their eggs and larvae. If temperatures rise again, you should be wary of tick bites.
