How to Keep Stink Bugs Out of Your Souderton Home

How Do Stink Bugs Enter Souderton Homes?

When stink bugs appear inside, it can almost seem like magic; we can assure you, however, that stink bugs aren't magical. What they're doing is accessing tiny entry points in your Souderton home, but some of these entry points can be seen and sealed. Today, we're going to talk about where you can look and what you can do to seal things up.

Your home has many gaps and, hopefully, all those gaps are sealed. If not, you should take a caulking gun and seal them up. Not only will this protect your home from stink bug invasion, it will keep rainwater from doing damage to the wood of your home.

  • At the point where plumbing pipes enter your home (pipe penetrations), there could be a gap. The hole created in your foundation wall is bigger than your pipes. If the seal has been damaged, that gap could become accessible for stink bugs.

  • Over time, gaps can form around window and door frames. Caulk is the solution to keep the rainwater out. If the seal is damaged, the gap is exposed and insects can get into your frame voids and possibly into your wall voids.

  • Just above your foundation wall is a set of horizontal wooden members which are called the sole plate. If this wood is softened by water damage, it can be the target of rodents, carpenter ants, and other wood-destroying pests. When holes appear, stink bugs will take advantage of them. If you're able, go around your entire home and inspect your sole plate. You may need to get under a deck or a porch to do so. If you find holes, seal them up.

  • Roof penetrations can lead to water damage and pest infestations. A gap around a sewer exhaust pipe, chimney, skylight, etc., can be exposed by squirrels, roof rats and other wildlife pests. This can let stink bugs in.

  • The point where your roof meets your soffits can get damaged by raccoons and squirrels as they scratch to gain entry, or a soffit can be damaged on a roof/soffit intersection. This may require more repair than a caulking gun can handle.


The frames around doors aren't the only way stink bugs can get in. If you have gaps in your weatherstripping or damaged door sweeps, those little insects can take advantage of them. These kinds of problems may require a realignment of your doors or a replacement of damaged stripping or sweeps. When you're done sealing things up, an easy way to see if you still have gaps is to make it dark inside when it is brightly lit outside; those gaps will shine!


When pests find a way into vents, they can sometimes damage the duct tunnel inside the home and give a route for pests to get in. Rodents are a particular issue in this area. If you have dryer exhaust vents, gable vents, or some other vent, make sure to cover them with metal screen material to keep rodents out and stink bugs from finding a path in.

Is Stink Bug Control Necessary?

Sometimes it is difficult or impossible to seal all of the entry points stink bugs can use to get inside. For extra protection or to bolster less-than-adequate defenses, residential pest control is the solution. Routine visits and appropriate treatments will give your exterior the protection it needs to reduce pest populations around your Souderton home and keep those pests outside where they belong.

The brown marmorated stink bug is an agricultural pest that becomes a nuisance pest during the fall months when it tries to overwinter in our homes. Stink bugs don't bite and they don't do any damage when they get in, aside from staining fabrics. They're just gross, so you can decide to put up with them; keep in mind, however, that there are many dangerous pests that can get into your home, such as termites, mosquitoes, ticks, and more. With Platinum Home Guard from Moyer, you can get essential treatments for a wide range of pests, and get the added benefit of keeping stink bugs out at the same time. It's a win-win!
