Box elder bugs are considered a nuisance when they cover homes and structures to sun themselves, usually near their host trees. When temperatures drop, they have been known to invade homes seeking warmth and will remain inactive until Spring. An active heating unit will awaken the box elders, only to invade the home to search for food and water. Aside from the foul odor they emit when squashed, and fecal matter stains, the box elder is not likely to do much damage. In order to control the population before they grow in numbers, contacting a box elder removal company is advisable.
Removing nearby box elder and maple trees is one strategy to create a long term solution to the box elders.
