Boxelder bugs are a nuisance in and around homes from fall through early spring. The bug overwinters as an adult in protected places such as, but not limited to, houses or office buildings. Removing female boxelder trees is the most permanent solution to the problem, although this option may not be practical or desirable. Additionally, laundry detergents offer safe, effective control when applied directly to the insects
For most people, the boxelder bug needs no introduction. This bug is about 1/2 inch long as an adult, black, will display three red lines on the thorax (the part just behind the head), a red line along each side, and a diagonal red line on each wing. Their immature forms are smaller, they are easily distinguished from the adults by their red abdomens and lack of wings.
