The Elm Seed Bug is a new invasive species in Idaho, discovered in the treasure valley in the summer of 2012. Elm seed bugs originate in south-central Europe, and are closely related in appearance to the Box Elder Bug, the only obvious difference is the size, with Elm Seed Bugs measuring at just under a quarter of an inch. Elm seed bugs are nuisance insects: They don’t bite or cause damage, but become problematic because of their large numbers and tendency to enter homes. Our quarterly pest plan will keep these creatures off and out of your home. Call for an estimate!
Elm seed bugs overwinter as adults, mate in the spring and lay eggs on elm trees. The larvae feed on seeds (particularly of elm trees) in May-June, and become adults in the summer. Like most true bugs, the Elm Seed bug has scent glands that produce an unpleasant odor when crushed.
Regular treatments are a must in dealing with these pests!
Adult box elder bugs are about 1/2-inch long, black with orange or red markings, including three stripes behind the head. Box elder bugs are primarily a nuisance because they enter homes and other buildings, often in large numbers. Fortunately, they do not bite people, but can stain walls, curtains, and other surfaces with their excrement. Adults feed on low vegetation and seeds on the ground during spring and early summer, and begin mating a couple weeks after they started feeding. Starting in mid July, they move to female seed-bearing box elder trees. where they lay eggs on trunks, branches, and leaves.
