In Minnesota, boxelder bugs emerge during spring to feed and start mating. By mid-summer, the bugs move to boxelder and other trees to lay their eggs. During late summer and early fall, boxelder bugs leave the trees to find protection from the cold of winter. You will often notice them emerging more in the spring in your home as it warms up and in the fall as temperatures drop. We have great packages and fall treatments to help prevent boxelder bugs from seeking shelter in your home or structure!
