Overwintering Pests

What are overwintering pests?

Overwintering pests are — just as their name states — pests that find their way into man-made structures like our homes to spend the winter in. Our homes provide them with a dark, quiet place to hide and a temperature-controlled space that keeps them warm throughout the cold winter months.

Examples of pests that overwinter in Michigan homes include the following:

  • Stink bugs
  • Box elder bugs
  • Asian lady beetles

Are overwintering pests dangerous?

No, overwintering pests are not pests that we need to worry about affecting our health or our home’s structural integrity. However, just because they aren’t dangerous doesn't mean we want them inside our homes.

Having insects living inside causes multiple problems, including attracting other pests to your home, like spiders, that want to hunt and feed on them. Having overwintering pests in your home also means that there are openings in your home that can not only let pests in but also rainwater, causing moisture issues that will attract more destructive pests like carpenter ants and termites.

Why do I have an overwintering pest problem?

Stink bugs, box elder bugs, and Asian lady beetles are attracted to the warm, sunny sides of buildings in the late fall when the temperatures cool off. As they move up the exterior walls, they make their way inside through spaces they discover around windows, rooflines, vents, and any other opening they discover.

Where will I find overwintering pests?

During the spring, summer, and most of the fall, overwintering pests are found outside in our yards, feeding and breeding on trees, in gardens, or in flower beds. Having these pests in our yards usually isn’t too problematic except for the fact that it puts them close to our homes.

Once these pests find their way inside, they move to dark, warm, quiet areas. Attics, roof eaves, wall voids, and crawl spaces make perfect habitats for overwintering pests. When spring rolls back around, they move back outdoors. Sometimes during a particularly warm, sunny stretch of weather, overwintering insects will emerge from their hideouts and you may see them on your walls or gathering around windows.
