Pest Guide : What are Boxelder Bugs?

What You Need to Know About Boxelder Bugs

Boxelder bugs (Boisea trivittata) are insects commonly found in North America, particularly in the western and eastern regions of the United States and Canada. They belong to the family Rhopalidae and are sometimes referred to as maple bugs, because they are often found on or near maple trees, as well as boxelder trees and ash trees. They are also found around other seed-bearing plants.

Because this species can be found around so many plants and trees, they are very common in North America and Northern Virginia, Maryland, and Washington, D.C.

How to Identify a Boxelder Bug Infestation

Boxelder Bugs have a distinct appearance.

Boxelder Bugs

Boxelder bugs are about 1/2 inch long, with a distinctive black and red coloring on their bodies. They have a flattened, shield-shaped body and six legs. Boxelder bugs feed on the sap of trees, and can occasionally cause damage to fruits and leaves.

In the fall, boxelder bugs seek out warm places to hibernate during the winter months. They often enter homes and buildings through cracks and crevices in the walls, and can be a nuisance to homeowners.


Common Questions About Boxelder Bugs

Boxelder bugs may be attracted to your property for a number of reasons. Some of the most common reasons include:

  • Presence of boxelder, maple, or ash trees: Boxelder bugs are often found on or near these trees, as they feed on the sap.
  • Warmth: As the weather begins to cool down in the fall, boxelder bugs seek out warm places to hibernate, such as your home or other buildings.
  • Light: Boxelder bugs are attracted to light, and may be more likely to enter your home if there is a bright light on at night.
  • Gaps and cracks in your home's exterior: Boxelder bugs can enter your home through small gaps and cracks in the walls, windows, doors, and other entry points.
  • Previous infestations: If you have had boxelder bugs in your home before, there may be a higher likelihood of them returning.
