The boxelder bugs, named after the tree in which they inhabit, are some of the peskiest creatures you will encounter.
Chances are, you’ve probably seen a swarm of these bugs glued onto the west side of your house, where they tend to reside in the sun on warm days. And while they are completely harmless, a big enough infestation can prove to be an eyesore and even just a little bit unsettling.
This guide will provide the low-down on boxelder bugs, including why they come to your house and how to get rid of them safely.
What Are Boxelder Bugs?
Boxelder bugs, scientifically known as Boisea trivittata, are distinctive insects with a black and red coloration that often catch the eye. These bugs primarily feed on the seeds of boxelder trees, as well as other similar trees like maple and ash.
While they don’t pose a direct threat to humans, boxelder bugs can become a nuisance when they invade homes during the fall, seeking shelter for the winter. They are attracted to the warmth of buildings and can congregate in large numbers, especially on sunny sides of structures.
Despite their name, boxelder bugs can also be found on other types of trees, and their presence is often marked by the characteristic reddish stains they leave behind on surfaces.
The Boxelder Bug Life Cycle
These bugs undergo a life cycle that includes eggs, nymphs, and adults. During warmer months, they inhabit trees, feeding on the sap and seeds. As temperatures drop, boxelder bugs seek protected locations to overwinter. While their presence indoors can be bothersome, boxelder bugs are generally harmless to humans and don’t cause structural damage.
When Are Boxelder Bugs Most Active?
Boxelders tend to be seasonal bugs with peak activity during the spring and fall when the temperature outside rises. This is where you’ll usually spot them either on the side of your house or in nearby trees.
On some rare occasions, you may even find a few dwellings inside of a heated basement if they have easy enough access inside of your home.
Why Do Boxelder Bugs Enter Homes?
Boxelder bugs are attracted to the heat retained by buildings, making residential spaces an inadvertent haven for them. Once inside, they may seek out concealed areas, such as wall voids, attics, or other secluded spots, where they can remain relatively undisturbed until the weather becomes more favorable. Implementing measures to seal cracks, gaps, and other potential entry points can help deter boxelder bugs from invading homes.
