Stink Bugs vs. Boxelder Bugs: Why Do They Come Inside?

What Are Stink Bugs?

Stink bugs are insects, easily recognized by their shield-shaped bodies and the strong odor they release when disturbed. The brown marmorated stink bug is one of the most common species in the United States and feeds on fruits, vegetables, ornamental plants, and crops. Their feeding habits can make them a concern for gardeners and agricultural growers.

Although stink bugs do not bite people or damage structures, they can become a nuisance when large numbers gather around homes. During cooler months, they seek shelter and may enter through small cracks and openings, often hiding in walls, attics, and other secluded areas.

What Are Boxelder Bugs?

Boxelder bugs are easy to recognize because of their dark-colored bodies and bright red markings along their backs. These insects are often found around boxelder, maple, and ash trees, where they feed on seeds and plant materials. They are most commonly noticed during warmer months when populations increase around trees and outdoor areas.

Although boxelder bugs are not harmful to people, they can become a nuisance when large numbers gather near homes. As temperatures begin to drop, they often search for sheltered locations to spend the winter and may enter buildings through small gaps and openings. Once indoors, they can become difficult to manage because they tend to gather in large groups.

Do Stink Bugs and Boxelder Bugs Come Inside in the Fall?

Yes, both stink bugs and boxelder bugs are known for seeking shelter inside homes during the fall. As outdoor temperatures begin to cool, these insects look for warm, protected spaces where they can spend the winter months. They commonly enter through small gaps and openings around the outside of a home, including:

• Cracks in the foundation

• Gaps around windows and doors

• Damaged screens

• Spaces around siding

• Openings near vents and soffits

Once inside, these pests may hide in walls, attics, and other protected areas. Homeowners often do not notice them until warmer weather arrives and the insects become active again.

Why Are Fall Bugs Attracted to Homes?

Throughout the spring and summer, stink bugs and boxelder bugs typically stay outside while feeding on plants and reproducing. As fall arrives and temperatures drop, they shift their focus from finding food to finding shelter.

A home can provide the ideal hiding place for these pests during the colder months. They commonly gather on sun-warmed surfaces like walls, windows, and roof edges while searching for cracks and gaps that allow them indoors.

How to Prevent Stink Bugs and Boxelder Bugs

The most effective way to prevent these fall invaders is to reduce the opportunities they have to enter your home. Making your property less attractive and sealing potential entry points can help keep these seasonal pests outdoors. Helpful prevention steps include:

• Seal Exterior Openings: Seal cracks and gaps around windows, doors, siding, and foundations to help prevent fall-invading insects from entering your home.
• Repair Damaged Screens: Fix tears or holes in window and door screens to block their common entry points.
• Clear Outdoor Debris: Remove leaves, vegetation, and other debris near the foundation to reduce hiding areas around your home.
• Maintain Exterior Caulking: Inspect and repair caulking around windows, vents, and other exterior openings where these insects may gain access.
• Reduce Pest Hiding Areas: Keep areas around your home clean and organized to eliminate potential shelter spots for insects.
• Inspect for Pest Activity: Regularly check your home’s exterior for signs of insect activity so problems can be addressed early.

What Should You Do If They Are Already Inside?

When stink bugs or boxelder bugs enter a home, eliminating the insects you see may only offer a short-term solution. A recurring issue with these pests usually suggests that openings or gaps around the home are allowing them inside.

A seasonal pest control expert can inspect the property, identify possible entry points, and recommend targeted solutions to manage the problem. Treating the issue before winter can help reduce the number of insects that emerge when warmer temperatures return in the spring.
