How Long Can Fleas Live in the Winter?

If you live in a warm area, you may be wondering how long can fleas live in the winter. While it is true that fleas die off when temperatures get below freezing, you should be aware that non-adult fleas can survive for up to 10 days. Fleas need temperatures that are at least 37 degrees to lay their eggs.

During the winter, you can still use flea preventative products on your dog or in your yard. It’s also important to use flea prevention products to prevent fleas from reproducing during the cold season. The cold weather kills the mature fleas as well as their offspring. As a result, fleas will try to survive the winter by clinging to warm animals or laying their eggs in warm places.

While adult fleas can survive the winter without a host, they cannot reproduce without blood. Without a blood meal, the female will not be able to develop and will die. Likewise, the pupae of a flea can remain dormant for up to six months. In most cases, an infestation will be caused by newly-hatched fleas.

When you find fleas in your house, you should immediately call a professional. You can also check for flea eggs on furniture. Flea eggs often fall into furniture seams and crevices. Fleas lay their eggs in these areas until they mature.
