The short answer is: Yes!
Cold weather and snow don’t even give us relief from fleas. As lovely as it would be to be rid of fleas in the cold weather, it’s just not the way it works.
Recently, my husband asked if our dogs could get fleas in the winter.
The subject came up due to Mira’s most recent failed friendship with a squirrel.
However, I told my husband that fleas could still be an issue in the winter, especially if our dogs come in contact with critters because fleas find squirrels more than a habitable host in the winter.
Do Fleas Die in the Winter?
Fleas are tenacious and always seem to find a way to live, even in hostile environments. What helps their survival is the flea lifecycle.
Larvae and eggs can survive in their immature state for extended periods, even in cooler temperatures.
Cocoons can retain this state for up to 30-weeks as long as the environment is at least 51.8⁰ F.
Fleas are very hearty and can survive in colder temperatures, but once temperatures reach 46.4⁰ F, unprotected fleas will die within 20 days of continuous exposure to these colder temperatures.

As temperatures continue to drop to 37.4⁰ or below, a flea’s life is cut down to 10 days.
But once winter is in full swing and temperatures drop to 32⁰ and lower, a flea can only survive for up to 5 days.
But if fleas can find shelter, such as in a house, garage, under a shed, in an animal’s den, or on an animal, fleas can survive if not thrive.
Can Dogs Get Fleas in the Winter?
Dogs can pick up fleas in numerous ways outside in the winter, especially if you have an energetic hunting dog like Mira.
Mira tends to protect our yard from critters. Unfortunately, Mira’s protection techniques tend to bring her into direct contact with rodents and the like, which is how fleas can easily find their way onto a dog.
However, there are other ways dogs can pick up fleas outside, such as:
- Sniffing around woodpiles
- Coming into contact with shrubs, leaves, or other dark areas fleas can find shelter
- Tall grassy areas
And the outdoors is not the only place our dogs can come into contact with fleas.
Immature fleas can exist for more than 7 months in the right conditions, like inside your home.
Dogs can pick up fleas in the house just as easily as outside. Immature fleas, like larvae and eggs, especially enjoy hanging out in carpets, furniture, along baseboards, and in your vehicle.
Plus, if your pup is a lucky dog, they get to go to daycare, which can also be a sanctuary for fleas.
Unfortunately, dogs can even get fleas from you.
Though humans are not the preferred host, fleas will happily catch a ride on you so they can get to your dog.
Things You Should Know About Getting Rid of Fleas
Dealing with a flea infestation is more than just a flea bath; it can take months to eradicate fleas from your home.
If you only treat the fleas on your dog and not your home, vehicle, and yard, your dog will continue to get fleas.
Most preventative flea medication works to deal with existing fleas as well as preventing future flea issues.
However, shampoos and oral medications such as Capstar can be excellent options as well.
Be sure to treat your dog and home at the same time to avoid a re-infestation.
There are few different options for treating your home:
- Essential oil sprays
- Flea spray for the yard like Vet’s Best Flea + Tick Yard Spray
- Home remedy options such as salt, essential oils, baking soda, or steam
- Professional exterminator services
Also, because flea larvae can exist for a long time, it is imperative to practice preventative measures.
An Ounce of Prevention…
Getting rid of fleas is hard; preventing them is easy.
Flea preventative options are available in a multitude of forms such as:

You can count on at least 1-2 follow-ups.
And those prices do not include the cost of treating your pup, either.
