Flea populations might slow down a bit, especially outdoors, but they don’t go away completely. To be safe, you’ll want to keep those flea treatments going even in the cold winter months.
What Happens to Fleas in Winter?
As winter arrives, many fleas and their eggs will die. Fleas prefer a temperature of around 75 degrees and are most active at this temperature.
As temperatures drop and hover near 50 degrees, fleas can cocoon and stay that way for months. No flea in any stage of development can survive freezing temperatures.
The best time to treat your dog with an insecticide is when it’s warm outside. If you wait until it gets colder, the insects may not have enough energy left to get out of the house.
How do fleas survive in winter?
Fleas need warm temperatures to survive. The inside of your home provides a warm environment to allow fleas to thrive year-round regardless of the season.
When temperatures fall below 60 degrees, fleas will begin to hibernate. Hibernation means that the fleas enter a state of suspended animation. They remain dormant and inactive for several weeks or months before waking up again.
If you notice signs of fleas on your pet after the first frost, you should consider treating them right away.
Do I need to treat my dog for fleas in the winter?

If you see signs of fleas on a dog after the first frost, then you should start treatment immediately.
If you’re unsure about whether or not to treat your dog for flea infestations in the winter, here are some tips:
• Check your home for fleas every month, no matter what the weather.
• Wash all bedding and clothing thoroughly, including linens.
• Remove carpets and rugs from your home.
•Keep pets indoors as much as possible.

• Seal cracks and crevices in your home, such as under sinks and behind appliances.
How do I get rid of fleas on my dog in the winter?
Use a flea carpet powder that kills the life cycle of the fleas. Wash all of your pet’s bedding in a hot water cycle. Any bedding or clothing that has come in contact with fleas should also be put on the hot cycle in your washing machine.
You can also use flea shampoo if you’d like, but make sure that it contains permethrin. Permethrin is an effective ingredient against both adults and larvae.

You can also use a topical spot-on product containing permethrin, which will kill the fleas on your pet within 24 hours.
