The Common Types Of Pests That Overwinter

It is common for insects to overwinter in Michigan, Ohio, Kentucky, Pennsylvania, West Virginia, and other states. The most common overwintering pests will be explored in greater depth below.

Asian Ladybugs

Asian lady beetles or ladybugs look similar to other ladybugs, but there are a few differences between them. During the winter, these bugs are going to enter your home and structure so they can stay safe. These pests create numerous problems because they will bite and they’ll release a bad odor.

Box Elder Bugs

Boxelder bugs target gardens during the summer months. They eat the seeds found on maple trees and box elder trees. Their behavior gets much worse during the winter. These black and red bugs will slip through the cracks in your walls and sneak inside. The good news is that they’re not dangerous and won’t bite. Nevertheless, they have a bad odor and can stain your walls and furniture when they’re smashed.

Cluster Flies

Cluster flies are one of the many flies that spend their entire lives outside. One thing that sets them apart is the fact that they begin as a parasite found inside of an earthworm. Once it transitions into larvae, it will spend the rest of its time outside. However, these flies are going to look for ways to survive during the winter months. They’ll try to slip through the wood of buildings and homes. If you don’t stop them, you will have to clean up their mess when winter is over.

Stink Bugs

Stink bugs are roughly half an inch in length. These bugs came from Asia and they’ve quickly become a nuisance for people living throughout the United States. During the summer, these bugs will target your vegetable crops and fruit trees. You have to act quickly because they can destroy your entire crop. During the winter, they’ll try to get inside. When stressed, this bug is going to release a terrible older. To get rid of them without creating a messy, you should use a vacuum to suck them up.

Leaf-Footed Pine Seed Bugs

The leaf-footed pine seed bugs will create a new generation annually. Adult bugs can reach ¾ of an inch and are light brown. In the summer, they eat pine cones and seeds. When winter comes, the adult bugs are going to look for shelter. If they can’t find shelter under the bark of nearby trees, they might try to enter your home. They tend to shelter in mass quantities. They don’t bite or damage property but you’ll need to get rid of them anyway.

They’ll use small cracks and crevices to enter your bedroom, bathroom, living room, kitchen, or garage.
