Can My Pet Get Fleas During the Winter?

You might be surprised to learn that while fleas thrive in humid, warm conditions – with the height of their activity in the spring, summer and even fall – they can and do endure the winter months by surviving in a variety of ways.

You can protect both your pet and your home by using preventative solutions all year round.

Flea Facts

Many pet owners falsely believe that fleas die off in the winter, and therefore choose to forgo proper parasite control when the cold kicks in. While it’s true that these pesky hitchhikers can’t survive freezing temperatures, they intelligibly seek out warmer locations when the mercury drops.

Location, location, location: The artificial environment created in our home by heating systems creates the perfect setting for fleas to survive and thrive. Optimum conditions for flea larvae are between 65-80 degrees Fahrenheit – the levels many homes are maintained at during winter months. Fleas can survive outdoors in temperatures as low as 33 degrees Fahrenheit for up to 5 days. This leaves them plenty of time to make themselves comfortable in your home.

It only takes one: A single flea can enter your home by catching a ride on you or your pet. That one parasite has the ability to cause an entire infestation, as signs of a few means others will come when they come to the new housewarming party. Flea pupae can also remain in their cocoons until the surrounding environment is warm enough for them to emerge. The pupae remain dormant for more than a year waiting for a suitable, warm situation. When an optimally warm habitat is detected, the pupae in stasis will all hatch together.

Flea eggs can live year round in protected areas like crawl spaces, porches and garages.

Pesky Predators: Fleas will bite people, but they prefer mammals with fur. While they pose a minor annoyance to us, they can be a huge danger to our pets. Some cats and dogs are allergic to flea saliva, which results in severe skin irritation and causes your pet to continuously scratch at the infected area. Cats and dogs can also develop anemia as a result of blood loss during a flea infestations.
