Boxelder Bugs are a unique insect that typically feed on sap from tender leaves or seeds produced by the female of the boxelder tree, ash, maple or a variety of fruit trees.
This insect is especially bothersome in late summer and early fall when it congregates on the sides of structures that receive the most sun. These are mainly the south and west sides of the structure.
Boxelder bugs are not only drawn to sunny areas but also to light or pastel colors such as yellow or light blue. Boxelder bugs may congregate by the hundreds or thousands eventually finding their way into soffits, attics, around windows and into wall voids.
Red and black “V” markings are prominent indicators of this species of insect that is often mistaken for the milkweed bug. The difference is that the milkweed bug has orange markings and is mainly associated with the milkweed plant.
Although boxelder bugs may emerge within the home during the late fall and winter months, it is important to know that boxelder bugs do not reproduce inside the home. Boxelder bugs do not cause harm to humans or livestock and are not known to transmit diseases.
There is one thing that is especially unpleasant to humans. It is the stink! Much like a stinkbug, the boxelder bug does emit a foul odor when disturbed or crushed.
Treatment for boxelder bugs is most effective when done in late summer before cool temperatures arrive. Good outside perimeter treatments are very effective during late summer and early fall to soffits, cracks and crevices, foundations where siding begins, and around all doors and windows.
Effective treatments can relieve interior populations during the winter months.
