Boxelder Bug

Scientific Name: Nuculaspis californica
Scientific Type: Nuisance Pests That Invade Your Home

Boxelder bug, scientifically known as Boisea trifolii, is a common insect species found in North America. They are known for their distinctive black and red coloring and feed on boxelder trees and other species of maples. In the summer months, they are commonly found on the outside of buildings, particularly those near boxelder trees.

Boxelder bugs do not cause significant damage to trees, but can be a nuisance to homeowners. They often find their way into homes through cracks and gaps in windows, doors, and siding. Once inside, they can release a foul odor and stain surfaces with their excrement.

Boxelder bugs are most active in the spring and fall when they are seeking food and shelter. In the spring, they emerge from their overwintering sites and move to the trees to feed and mate. In the fall, they move back to buildings and other structures in search of a place to spend the winter.

Control of boxelder bugs can be achieved through exclusion and extermination. To prevent them from entering your home, make sure that windows, doors, and other points of entry are well-sealed. If they have already entered your home, they can be vacuumed up or trapped and released outside. Pesticides can also be used, but should only be applied by a professional and with caution to protect non-target species.

In summary, boxelder bugs are a common insect species that can become a nuisance to homeowners, but do not cause significant harm to trees. Proper exclusion and extermination measures can help prevent them from entering homes.
