Quickly Identifying Overwintering Pests

In the United States, there are many overwintering pests. If a pest overwinters, it enters homes to shelter during the winter months. These pests are going to use your attic and wall voids to stay warm during the winter.

Which Pests Overwinter?

When it comes down to it, numerous pests overwinter. Below, you’ll learn more about some of the most common overwintering pests in Richmond.

Box Elder Bugs

This minor garden pest won’t create too many issues during the spring and summer. Around this time, it will eat the seeds of maple trees and box elder trees. When winter arrives, it is going to create several problems. It’ll try to sneak into your home and stay there until winter passes. Boxelder bugs are half an inch in length with black and red marks. Thanks to their compact size, they can easily squeeze through small cracks and crevices. Don’t crush them because they’ll release a terrible odor in your home.

Asian Lady Beetles

Virginia homeowners also have to worry about Asian Lady Beetles. They’re one of the most common overwintering pests as well. Some can bite, but most won’t pose a risk to humans. These beetles will try to sneak into your home during the winter months and stay there until it gets warm. Once again, they shouldn’t be crushed because they’ll release a bad odor.

Cluster Flies

While cluster flies prefer being outside, they’ll try to enter homes and other buildings during the winter months. Alternatively, they’ll try to hide behind loose tree bark. The cluster in the name tells you something about the behavior of this fly. They cluster together, so they’re going to create an unsightly mess when spring arrives.

Leaf-Footed Pine Seed Bugs

Leaf-footed Pine Seed Bugs are one of the largest overwintering pests you’ll have to worry about. In addition to this, they can create more problems than the others because they’ll produce a new generation each year. Adults each 3/4” and more are dull brown. During the warm months, they consume pine cones and seeds. When it gets cold, they’re going to try to sneak into buildings. They prefer hiding under bark but will hide in buildings too. When their hiding spot is warmed by the weather or HVAC equipment, they’ll emerge.

Their large stature can frighten you. The good news is that pine seed bugs do not bite or cause damage to your property. Nevertheless, you’ll need to clean up their mess.

Stink Bugs

Finally, you’ll need to worry about Brown Marmorated Stink Bugs. These bugs are new to the United States, but they’re more problematic than many other overwintering pests. These bugs came from Asia and quickly created problems for Americans. Now, they’re found in many states, including Virginia. During the summer, they’ll stay outside and eat vegetable crops, ornamental plants, and fruit trees. If gardeners and farmers aren’t careful, stink bugs will ruin their entire crop.

When the colder months arrive, stink bugs will find a way to enter homes and other structures. Their large size means they’re impossible to ignore. Furthermore, they’ll release a bad odor when stressed. To get rid of them, grab your vacuum and suck them up. Be ready to cover your nose because they’ll release a stinky odor.

Entry Points To Worry About

Joints In Bricks & Mortar

Window Frames

Be sure to check out the area around your window frames. Many window frames have been properly caulked around the top and sides to keep water from entering. However, the bottom might be left untreated. If this is the case, bugs will easily be able to enter your home. Stop this from happening by sealing the gaps using caulk.


You also need to check the gaps around your fascia and wooden clapboards. There will be gaps where the two boards meet. While you could use caulk to fill the gaps, it is best to use insulating cord foam. Sealing the cracks stops overwintering pests from entering your home and staying there during the winter.

Attic Vents

Soffit and attic vents need to be protected with screens. Furthermore, the screens need to be in excellent condition. They shouldn’t have any cracks, tears, or gaps. If they have holes, bugs will squeeze through them. Replace damaged screens immediately.


Utilities need to enter your home somewhere. For instance, your internet cable will enter your home from outside. If the hole has not been properly sealed, bugs will be able to enter the utility hole. It is pertinent to seal this crack to stop bugs in their tracks.

More Materials At Your Disposal
