It is not uncommon for people to wonder, “Do fleas live in the winter?” The answer is yes, but not the way you may think. While most insects hibernate during the winter, fleas can survive the cold by laying eggs or resting on a host’s body. This means that fleas can survive the winter months if they are in warm places, such as your house or garage.
Fleas need to stay warm to survive, so they find warm places to hide. This is why they choose homes, even in cold weather. A warm, dry place to live, combined with a pet, can give fleas a safe place to survive. Fleas also seek shelter under bushes and in crawlspaces.
Regardless of the season, you can protect yourself from flea infestations by treating your home with a preventative flea treatment. Fleas are opportunistic, so they will ride your pet into your home. They will then seek out their hosts, which will usually be your pet, in order to survive.
Fleas need a temperature that stays below 37 degrees Fahrenheit to survive. They will begin feeding on your pet’s blood within 24 hours and then mate and lay their eggs within 36 hours. Once these eggs hatch, the fleas will emerge from their cocoons when temperatures are warm enough for them to survive. Fleas can live up to seven months indoors in a warm place.
