How Cold Will Kill Fleas?

While you might think that freezing temperatures will kill fleas immediately, this is actually not the case. It takes ten days for flea eggs to become inactive when exposed to freezing temperatures. The same is true of fleas that have pupae. They will remain in the yard while temperatures remain above freezing, and they will hatch again when the weather becomes warmer again.

The coldest temperature that will kill fleas is around 70 degrees Fahrenheit. Although adult fleas are the most susceptible to this temperature, cold weather will also kill eggs and larvae. If you live in a colder area, it is important to keep your home and pets protected.

Although it is impossible to completely eliminate fleas in the winter, you can apply flea preventative to your pets. Cold temperatures will kill adult fleas, but they won’t be eliminated for the season. Cold temperatures will reduce their population in your area, but you’ll still need to watch for tick bites when temperatures rise.

Although the cold kills most fleas, they can survive winters in heated homes. This is because they are unable to breed in cold temperatures, and the cold will give them a rest from itchy bites. Fleas will return in the spring. But if you keep your home warm and dry, you can keep fleas from repopulating in your home.
