Once inside, the best method of control is to suck up the occasional bug with a vacuum cleaner. Sprays may need to be repeated as more boxelder bugs arrive, especially when using soapy water. Caulk all openings around windows and doors and in walls, siding or foundations.Ĭlusters of bugs on the sides of buildings can be sprayed with registered insecticides, insecticidal soap or hot, soapy water. If you’ve been invaded by boxelder bugs (or other insects) in the past, try to seal up all possible entry spots. The best means of preventing problems with boxelder bugs is to prevent entry into your home. Choose species other than boxelder when planting shade trees. However, the adults are good fliers, and can move a considerable distance from host trees, so this will not eliminate boxelder bug problems. Also, remove any accumulations of boxelder, ash, elm and maple seeds since the bugs can feed and reproduce on these, as well as on trees. Removing boxelder trees or spraying heavily infested trees with a registered insecticide in mid-summer may help reduce boxelder bug numbers. However, their mere presence certainly can be a nuisance. They will not bite humans or pets, and they do not damage food or other items in the home. Although they do not feed or reproduce inside the home, boxelder bugs may stain curtains and walls. But should they be warmed up by the furnace or sunshine, they become active and may crawl into the rooms. They often gather in large congregations on walls or foundations when seeking entry.Īs long as the bugs remain cold within walls or attics, they are inactive. They enter buildings through small gaps around windows, doors, and pipes and through small cracks in the foundation or siding. Boxelder bugs like sunny areas and are attracted to buildings with a lot of southern exposure – regardless of the color. In their search for a nice hiding place to spend the winter, boxelder bugs often end up inside our homes. They continue to be active late into the fall and are often seen congregating in sunny spots on the south sides of buildings, trees and rocks on warm afternoons. The adults that develop from these eggs leave the trees to find places to spend the winter. Nymphs mature into adults by mid-summer, and these adults lay eggs for a second generation. They rarely cause significant damage to any plants. They can be found on other plants, such as ash, maple and occasionally on strawberries, grasses, and various other plants, but normally cannot complete their development on these other plants. During the summer they are found primarily on female boxelder trees ( Acer negundo) where they feed by sucking plant sap from leaves and developing seeds. They tend to be most abundant after summers when we have had a very warm May and a dry July, but their numbers also vary a lot from place to place regardless of the previous months’ weather.Īfter the bugs emerge from overwintering sites in the spring, females deposit small, red eggs on host plants. Nymphs (immatures) are bright red with darker heads and look like the adults, but without developed wings. The gray and red adults are about ½ inch long. Boxelder bugs( Boisea trivittatus, Family Rhopalidae, scentless plant bugs) are common insects from mid-summer through fall, and sometimes in spring.
