Boxelder bugs feed mainly on boxelder tree seeds and newly developing leaves, which may result in discoloration of the foliage. They will also occasionally feed on the fruits of plum and apple trees. If you have many of these trees on your property, you are more likely to see boxelder bug activity throughout the year.

Where will I find boxelder bugs?

During the summer months, boxelder bugs are most commonly found around boxelder trees, as well as maple and ash trees. In autumn, boxelder bugs become more sociable and congregate on the south side of rocks, trees and buildings where the sun hits. After large masses gather, they migrate to nearby buildings or homes to overwinter. These pests tend to hide in small cracks and crevices in walls to insulate themselves from the cold winter temperatures. In late March to early April, adults leave their overwintering sites to return to their host trees for the warmer months.
