Properly sealing your home can help, but there is no guarantee that you’ll be able to keep these pests out.

Even if you leave a small gap, they can use that gap to enter your residence. Regardless, it is wise to fill the gaps mentioned below since it will reduce the likelihood that you’ll encounter an overwintering pest infestation.

Start With Small Gaps & Openings

First, you should begin by fixing small gaps and openings. Even though these gaps are small, overwintering pests can still use them to enter your home. Seal these gaps using pest-proofing materials. Doing so will stop overwintering pests, occasional invaders, and other pests from entering your home.

Install A Protective Exterior Barrier

It may be a good idea to use a protective exterior barrier to keep bugs away from your residence. A professional exterminator will use high-quality materials to create a protective barrier around your home. Once they’ve finished, bugs in your area will be hesitant to cross the barrier so they won’t be able to enter your home.

Although you can buy over-the-counter materials to create a protective barrier around your home, professional products are better.

Where To Check For Entry Points

When attempting to seal your home, be sure to check for the following entry points.

Brick/Mortar Joints

First, you should check the brick-and-mortar joints around your home. Go outside and look near the top of the home where the siding or molding touches the bricks. You may find a small gap between the joints. Bugs can squeeze through this hole and enter your home. Suffice to say, you should seal this gap using a high-quality sealant.

Around Window Frames

When windows are first installed, it is common for the sides to be caulked. The top will always be caulked to prevent water from entering. However, some installers will not caulk the bottom of the window frame. Bugs can enter through this gap. Seal the gap to prevent bugs from entering your residence.

Around The Clapboard

Don’t forget to look for gaps around your home’s wooden clapboard. There will likely be gaps around the fascia board and clapboard because of the uneven surface. While you can use caulk to block this entry point, it is much easier to use foam insulation.


Remember that your attic has vents to help control humidity. The vents are very important for reducing humidity. Your vents should be protected using a screen. Doing so will prevent bugs from slipping through. If you already have a screen, it needs to be in excellent condition. Replace any screen that has rips or tears.

Openings For Utilities

You’ll also need to look for holes around openings for utilities. For instance, you may find small gaps around cables, pipes, and vents. These gaps must be sealed completely to prevent bugs from entering your home. While there are various ways to resolve this problem, it is best to use old pot scrubbers. Using scrubbers that are already used will make them easier to deal with. They’re more flexible and easier to cram into the hole.
