How Do Pests Survive the Cold Weather?

As the temperature begins to drop and the leaves start to fall, we know winter is on its way. For most of us, this means breaking out the heavy coats and scarf collection. As we spend more time inside our cozy homes, it raises the question: how do problem insects and rodents survive the winter? Luckily, our team of pest management experts has some answers for you!


Male mosquitoes do not live very long, usually about ten days. Females, however, are resilient and can live up to six months! Female mosquitoes will begin to look for places to spend the winter when temperatures drop in the fall. This could be under loose tree bark or in tall grass. Once they’ve found a suitable spot, they’ll build a nest out of leaves and other debris. The female mosquito will lay eggs inside this nest—usually between 100 and 300. She’ll then seal up the nest and wait out the winter.

When spring arrives and the temperature rises again, the eggs will hatch, and new mosquito larvae will emerge. These larvae will then mature into adult mosquitoes, and the cycle will start again.


Mice have multiple strategies to survive the winter as one of North America’s most common household pests.

Murine Warmth Pool

One way mice stay warm in winter is by huddling with other mice. By huddling together, they create a ” murine warmth pool.” This heated pool helps to keep them warm and cozy during even the coldest nights.

Nest in Your Home

Another way mice stay warm is by making themselves a nest inside your home. These nests are usually made of soft materials like insulation or shredded paper. You might find one behind your furnace or in your attic—so be on the lookout!

Brown Fat

Mice also have something called “brown fat.” This type of fat helps generate heat, which helps keep them warm during cold weather.


Spiders are another common household pest that does quite well in colder weather. That’s because most spiders can spin webs that act as insulation, trapping heat and keeping the cold out. Additionally, many spiders will enter a state of dormancy during the winter, slowing their metabolism and becoming less active. This helps them conserve energy so they can make it through until spring.
