What Are Stink Bugs?

Stink bugs, also known as shield bugs, are insects in the family Pentatomidae. The brown marmorated stink bug and the green stink bug are the most commonly found species in Pennsylvania. Stink bugs are so named because of the foul-smelling odor they emit when threatened or crushed. This odor is a defense mechanism that helps them deter predators.

Stink bugs are easy to identify due to their distinctive shape and size. They have a shield-shaped body that is typically brown or green in color. They also have six legs and two antennae. While they are generally harmless to humans, they can be a nuisance due to their unpleasant odor.

Why Are Stink Bugs Becoming More Common in Pennsylvania?

Stink bugs are not native to Pennsylvania, but they were first detected in the state in the late 1990s. Since then, their population has exploded, and they have become a common pest in the area. There are several reasons why stink bugs are becoming more common:

  • Lack of natural predators: Stink bugs have few natural predators in Pennsylvania, which means their population can grow unchecked.

  • Climate change: Warmer winters and longer growing seasons may be helping stink bugs thrive.

  • Urbanization: As more land is developed for housing and commercial use, stink bugs are forced to seek out new habitats, including homes and gardens.

How to Get Rid of Stink Bugs in Pennsylvania

If you have a stink bug infestation in your home or garden, there are several things you can do to get rid of them:

1. Seal up your home

Stink bugs can enter your home through small cracks and openings. Seal up any gaps around doors, windows, and other entry points to keep them out. Use caulking or weather stripping to seal gaps around windows and doors, and use expanding foam to fill gaps around pipes, electrical wires, and other entry points.

2. Vacuum them up

If you see stink bugs in your home, use a vacuum cleaner to suck them up. Be sure to dispose of the vacuum bag outside of your home to avoid releasing the odor. You can also use a handheld vacuum or a crevice tool to reach tight spaces where stink bugs may be hiding.

3. Use sticky traps

Sticky traps can be an effective way to catch stink bugs in your home. Place the traps near windows or other entry points. You can purchase sticky traps online or at a hardware store.

4. Remove their habitat

Stink bugs are attracted to certain types of plants, including fruit trees, vegetables, and ornamental plants. If you have these plants in your garden, consider removing them or covering them with a mesh netting. You can also prune trees and shrubs to reduce the amount of habitat available to stink bugs.

5. Call in the professionals

If you have a serious stink bug infestation, it may be best to call in a pest control company like Environmental Pest Solutions. They have the experience and expertise to deal with stink bugs and other pests safely and effectively. They can also provide preventative measures to keep stink bugs from returning.

The Importance of Professional Stink Bug Control in Pennsylvania

While there are several DIY methods for getting rid of stink bugs, it's important to note that these methods may not be effective for large infestations. Stink bugs can reproduce quickly, and a single female can lay hundreds of eggs in a season. This means that even if you remove the stink bugs you see, there may be more hiding in your home or garden.

This is where professional stink bug control comes in. A pest control company like Environmental Pest Solutions has the expertise and tools to identify the source of the infestation and eliminate it at its root. They can also provide preventative measures to keep stink bugs from returning.

Professional pest control is also important for protecting your health and safety. Many DIY methods for getting rid of stink bugs involve the use of harsh chemicals that can be dangerous if not used properly. A pest control company will use safe and eco-friendly methods to get rid of stink bugs without putting you or your family at risk.


Stink bugs are becoming an increasingly common pest in Pennsylvania, but with the right strategies, you can keep them out of your home and garden. Remember to seal up your home, vacuum them up, use sticky traps, remove their habitat, and call in the professionals if you have a serious infestation. With these tips, you can enjoy a stink bug-free home and garden all year round.
