While most of us look forward to the holidays that come with the onset of winter, many of us don’t look forward to the snow, ice, and freezing temperatures that also come along with it. Pests feel the same way we do about cold weather and have developed several different methods to survive these frigid temperatures. So where do pests go in the winter? As much as we’d like to believe they just disappear until spring, unfortunately this isn’t the case. Pests have developed 3 major ways to survive winter:

MIGRATION

Migration is the seasonal movement from one region to another. Just like humans, pests want to go where it’s warmer when the weather gets cold. Some pests will move to southern regions to escape the cold and return to the northern areas when the weather starts to warm. One of the most well known examples of migration is the monarch butterfly.

HIBERNATION

Hibernation is a period of time spent in a dormant state in order to survive the unfavorable conditions of winter. Bears aren’t the only animals that hibernate during the winter! Ladybugs hibernate at high elevations. Wasps seek shelter in eaves and attics of houses or barns to hibernate. Many other pests hibernate in trees, leaf debris, under logs, and under rocks. Honeybees stay in hives during the winter and form clusters when the temperatures start to fall.

OVERWINTERING

Overwintering is the process in which pests pass through or wait out the winter season in sites that provide protection from the cold winter temperatures. Ladybugs, box elders, and stinkbugs overwinter in secluded, sheltered places like your home. These pests tend to congregate in large numbers so if they overwinter in your home they could infest in large numbers. Pests like rodents, cockroaches, spiders and flies remain active during the winter in our homes. They move indoors in search of warmth and food. Spiders are relatively harmless but flies can contaminate food and surfaces. Rodents can not only contaminate your food and insulation but can also chew through wood causing structural damage and chew through wires putting your home at risk of fire and other issues.
Now that you know where pests go in the winter you can help get your home ready to prevent these overwintering pests from invading your space. If you suspect you have a winter pest problem contact a professional who can help identify the pests and help you develop a treatment and prevention plan.
