The flea life cycle and ideal conditions for fleas

To understand what happens to fleas in winter, it’s important to have a basic understanding of the flea life cycle and their ideal living conditions.

Fleas thrive in high humidity and warm temperatures, optimally above 70 degrees Fahrenheit, which is why southern, coastal states have the most active flea populations.

Fleas go through four distinct life cycle stages – egg, larvae, pupae, and adult.

Most of the time, flea eggs are laid directly on a pet’s skin where they are kept warm by the skin and coat. However, flea eggs are smooth and can fall off of pets and into carpet, bedding, or plush furniture. As larvae, fleas move away from light sources and prefer warm, dark, and moist areas. Indoors, they live in carpet fibers, between floorboards, and under furniture. Outdoors, they settle in grass, branches, leaves, and soil. In fact, larvae start to die off if temps are above 95 degrees so that’s a big reason they seek shade and coolness.

Flea larvae spin a cocoon around themselves and by doing so enter the pupal (also known as the cocoon stage). Flea pupae can survive for a long time (months even!) in the cocoon, emerging into adults only when they’re triggered by movement of a potential host.

Adult fleas are attracted to light and spend time in the open air on the coats of animals. In normal circumstances, an adult flea will live up to three weeks and lay up to 500 eggs. Fleas in all stages can adapt to “famine” conditions and go for extended periods without a meal. For example, hatched adult fleas can live inside their cocoon waiting for a meal up to six months, while in ideal lab conditions adult fleas can survive months, although in real-life environments, that number is typically two days to up to two weeks.

Do fleas die in the winter? How long can fleas survive freezing temps?

Fleas can survive some winter temperatures but, according to Michael Dryden, DVM, fleas cannot survive freezing temperatures for more than 5 days in a row. In general, it takes two hard freezes to kill fleas outdoors.

That said, fleas are adept at finding ways to survive even the harshest of winters by attaching themselves to warm-bodied animals (like your pets) or finding their way indoors. Once fleas are inside, they can survive indefinitely as long as they have a host to feed on.

Unlike outdoor fleas, the indoor flea cycle won’t ever die off unless the fleas are treated and the situation is addressed.

Recap: How cold does it have to be to kill fleas?

If fleas are not otherwise snuggled into a warm host, they cannot survive temperatures below 32 degrees Fahrenheit (or 0 degree Celsius) for more than 5 days in a row.

How do cats and dogs get fleas in winter?

There are two main ways that fleas find their way onto your pet during the winter months.

1. Via other animals: When you take your dog to the dog park, cat-sit a friend’s cat, take your pet to the vet, etc., fleas and flea eggs on other animals can find their way onto your pet.
2. Flea eggs in the home: If a pupal-stage flea that’s ready to become an adult flea egg is already somewhere in your home, it can hatch at any point during the year, including winter, and cause a flea infestation.
