Overwintering 101

Most homeowners mistakenly believe that pests simply go away, disappear, or die off during the winter months. While it is true that many insects seek shelter in buildings during the cooler months, often called overwintering, they are still around and can cause problems. Overwintering pests generally become a problem in the fall and again in the spring. Let’s take a closer look at what overwintering really means and the pests that tend to behave this way. We will also discuss some steps that you can take to prevent your home from becoming a target.

Overwintering

Conditions in New England can be difficult for survival for many species of wildlife and insects. The sub-zero temperatures, ice, snow, and limited access to food can make activity nearly impossible and survival is not a given. Many species then turn to hibernation or migration to “overwinter” in our region. The inside walls, attic, basement, or crawl spaces of your home may make for an ideal location to overwinter. Pests such as stink bugs, boxelder bugs, beetles, and even rodents spend the colder months overwintering until the climate improves. They can do this as adults or in other stages of the life cycle. In addition to your home, overwintering locations can include: inside sheds, under tree bark, or beneath fallen leaves or other plant matter on the ground, among other places. The ultimate goal is to find a location that is protective and allows for survival.

The Signs

Many homeowners do not even know that pests have been overwintering in their home until the warmer months when they start to reemerge from their winter hiding spot. Most overwintering insects go unnoticed, but there are signs that you may want to be aware of. In the late fall, be aware of beetles, ladybugs, or other insects clinging to the side of your home, especially where the direct sun hits your structure. Another sign is usually in the early spring when these insects begin to reemerge like the stink bugs. In those cases, the sign will be an actual insect or many insects in your home trying to make their way outside. They will head toward windows and light sources in your home as a way to find a way back outside.

Prevention

The best way to prevent insects from choosing your home is to eliminate access to the interior of your structure. This means doing a thorough examination of your property and sealing all openings, gaps, cracks, and utility openings. Seal doors, windows, piping, vents, chimney openings, and all the ways you can visually see that an insect could find a way into your home.
