Which Pests Stay Dormant During the Winter Months?

The colder months of fall and winter are almost upon us, which means that we can snuggle up in our flannel blankets, sweaters and scarves. We can start to plan cozy nights by the fireplace, (or whatever your main source of heat happens to be), with a good book and a cup of hot tea. But while we are bundled up warm against the cold weather, outside, pests are looking to keep warm also. Will they end up in your home looking for shelter? Or do they stay dormant? Keep reading to find out which pests stay dormant during the winter.


Ants make their nests underground to house them all year round, unless it becomes too cold for them. Many species of ants will tunnel underground further in search of warmth, but it is common that many will not survive the winter. Certain species can withstand the freezing temperatures, such as the Argentine ant, but they become dormant.


The female mosquito can survive the winter, but she will hibernate in areas such as burrows, storm drains or caves. In preparation, she will stop feeding on blood and instead begin storing more fat. Sometimes it may be the case that she contains eggs while staying dormant. However, only certain species of mosquitoes can survive over the winter months as larvae. Male mosquitoes cannot survive the winter and they die off as the weather becomes colder.


Most species of ticks, like the American Dog tick and the Lone Star tick, become dormant during the winter months to conserve water and produce the substances that they need to stay warm. There are particular species, such as the Black-Legged tick, that will continue to look for a host as long as the temperatures remain above freezing. Even during the winter months, you should check yourself and your pets for ticks whenever you are outside. While ticks begin to emerge back into nature when the temperatures warm up, remember that there are more animals (and people) outside to feast upon.


Cockroaches are able to withstand colder temperatures, but will usually slow down in activity during winter. This means that they may move into your home to keep warm in areas such as your basement or crawl spaces. Thankfully, they reproduce much more slowly at this time.

Despite the fact that these pests slow down in activity or are dormant during the winter months, pest infestations in your home are still possible. Contact Dayton’s Pest Control for pest solutions.
