How to Get Rid of Boxelder Bugs in House: Simple Guide (2025)

Boxelder bugs – often called maple bugs or boxelder insects are small, black-and-red creatures that become a significant nuisance during the fall season. For homeowners, these pests can quickly become a minor inconvenience to a frustrating problem, especially when they invade homes in large numbers. If you’ve noticed these red and black bugs gathering on your windows or walls, you might be wondering: Are boxelder bugs harmful? Or perhaps, how to get rid of boxelder bugs in the most effective way possible. Don’t worry, this guide will cover everything you need to know about these pests—from their behavior to how to keep them out of your home.

What Are Boxelder Bugs?

Boxelder bugs, scientifically known as Boisea trivittatus, are a type of “true bug” that’s closely related to stink bugs and cicadas. While they are not considered dangerous, they do have a reputation for being an annoying presence in many homes. These bugs are easy to identify, thanks to their distinctive black bodies marked with bright red or orange stripes. Their overall appearance resembles a red and black beetle, and they are about 1/2 inch in length.

Maple bugs are commonly found around boxelder maple and ash trees, and other types of trees with seeds that the bugs feed on. As fall approaches and temperatures begin to drop, boxelder bugs will often migrate indoors in search of a warm place to overwinter, making them a seasonal nuisance for homeowners.

Boxelder Bug Life Cycle and Reproduction

Understanding the boxelder bug life cycle is key to effective control. In spring, adult boxelder bugs emerge from their winter hiding spots and females lay eggs on the bark of host trees, primarily boxelder, maple, and ash trees. These eggs hatch into bright red nymphs that go through several growth stages before becoming adults. This reproductive cycle means that addressing an infestation early is crucial to prevent larger populations later in the year.

What Do Boxelder Bugs Eat?

Boxelder bugs have very particular feeding habits, and the main item on their menu is the seeds of the boxelder tree. They will also feed on the newly developing leaves of these trees, which can sometimes lead to discoloration of the foliage. Although their feeding habits are unlikely to cause significant damage to the trees, they can leave behind unsightly spots. Occasionally, they will also feed on fruits like plums and apples, though this behavior is less common. So, what do maple bugs eat? Primarily the seeds of their host trees.

Are Boxelder Bugs Harmful?

One of the most common questions homeowners ask is, Are boxelder bugs harmful? Fortunately, boxelder bugs are not dangerous to humans. They don’t bite, and their piercing-sucking mouthparts, while capable of puncturing skin when handled, are not known to cause any serious harm. However, the small bites can lead to mild irritation, resulting in a red spot similar to a mosquito bite.

That said, while they may not be physically harmful, boxelder bugs can be a nuisance. When crushed or disturbed, they release a strong, unpleasant odor. Their fecal matter can also stain fabrics or leave behind reddish-orange marks on walls and surfaces, which could lead to fabric discoloration. If not addressed, these stains can be hard to clean, further adding to the frustration.

Where Do Boxelder Bugs Live?

Boxelder bugs are most found in areas where boxelder trees and maple trees grow in Canada. And while they thrive in warm climates, they are known to travel long distances in search of suitable living conditions.

In the spring, adult boxelder bugs emerge from their hibernation sites to begin feeding on the seeds and leaves of their host trees. As the fall season approaches and the temperatures drop, they begin looking for a warm place to spend the winter. It’s at this point that they often find their way indoors, causing homeowners to wonder how to get rid of boxelder bugs before they become a persistent issue.

Boxelder Bug Behavior – Autumn Congregation and Migration Indoors

As autumn approaches, boxelder bugs congregate in large groups on sun-warmed surfaces such as rocks, trees, and buildings facing sunshine. These bugs gather in these areas to soak up the sun, warming themselves before the cold weather sets in. Once large groups have formed, the bugs begin migrating to nearby buildings and homes, seeking sheltered areas to overwinter.

You might see boxelder bugs climbing up the side of your home or gathering around windowsills or door frames. Once inside, they tend to hide in small cracks and crevices within the walls or around windows, where they can safely wait out the winter months.

How to Prevent Boxelder Bugs from Entering Your Home

The best defense against boxelder bugs is prevention. Getting rid of maple bugs begins with keeping them out of your home in the first place. Here are a few tips for safeguarding your home from an maple bug infestation:

• Seal Cracks and Crevices: Boxelder bugs can squeeze through even the smallest gaps in windows, doors, and walls. To prevent them from getting inside, seal any cracks and crevices around your home with silicone or silicone-latex caulk. Pay special attention to areas around window frames, doors, and vents.
• Repair Screens: Boxelder bugs are skilled at getting through damaged or old window screens. Check your window and door screens for any holes or tears and replace them if needed.
• Install Door Sweeps: A door sweep can be an excellent way to seal gaps at the bottom of exterior doors. This simple tool can prevent boxelder bugs from entering your home through doorways.
• Maintain Your Lawn: Boxelder bugs are attracted to boxelder trees, so keeping these trees healthy and trimmed can help reduce the likelihood of bugs taking up residence near your home.

How to Get Rid of Boxelder Bugs Once they’re inside

If boxelder bugs have already found their way inside, don’t panic. There are several ways to manage them and exterminate box elder bugs:

• Vacuum Them Up: A vacuum cleaner is one of the easiest and most effective ways to get rid of maple bugs. Simply vacuum them up and immediately dispose of the bag or empty the contents to prevent them from escaping. Avoid crushing the bugs as this will release their unpleasant odor.
• Use Soapy Water Spray: What kills boxelder bugs instantly? A simple DIY spray made with dish soap and water. Mix a tablespoon of dish soap in a spray bottle with water and spray it directly on the bugs. The soap breaks down their exoskeleton, effectively killing maple bugs on contact.
• Don’t Kill Them in Walls: If boxelder bugs have made their way into the walls, it’s important to avoid killing them there. Dead bugs can attract other pests like dermestid beetles, which may create even more problems. Instead, use a vacuum to remove any visible bugs.
