The Myth That Fleas Die in Winter

The myth that fleas die in the winter is a myth, but in fact fleas do survive in cold temperatures. They are most susceptible to the freezing temperatures when they are adults, but they can survive indoor temperatures. That’s why you should be proactive about flea prevention all year long.

Fleas don’t die overnight when the temperature drops below freezing, but they will overwinter in organic material, including the organic matter from nearby pets. They can also overwinter on wild animals and pets that live in your area. During this time, they will shut down until the weather is more pleasant.

Fleas don’t live for long, but they can reproduce very quickly. The eggs will survive the cold months of winter and hatch out in spring. Then they’ll start the whole cycle again. So, it’s important to keep your home clean and disinfected. A little bit of flea killer will help. Once you’ve applied the insecticide, you’ll have an effective treatment for fleas that will keep them from re-infesting your house.

While the change of seasons doesn’t kill fleas, the changing weather does affect the population of these pests. While cold temperatures are ideal for killing ticks, they don’t kill fleas. Changing weather conditions may make them thrive, which is why fleas are resilient to the cold temperatures.
