Boisea trivittata is an American species of true bug, commonly known as the Box Elder Bug, the Zug, or Maple Bug. It is found primarily on boxelder trees, as well as maple and ash trees. The adults are about 12.5mm (.49 in) long with a dark brown or black coloration, relieved by red wing veins and markings on the abdomen. Nymphs are bright red.
Damage: Box elder bugs are not dangerous insects. They are considered pests because of their invasive hibernation patterns. They do not bite humans nor do they cause damage to buildings.
Box elder bugs inhabit maples and ashes, and seed-bearing box elder trees, in warm seasons. In winter, they can be found in interior areas such as houses.
Feeding and Breeding: Box elder bugs feed on soft plant tissues, such as leaves and flowers.
Treatment: Home remedies include mixtures of soap and water, boric, weather stripping, and duct tape. The best way to eliminate and prevent them is to hire a professional to treat the outside of your home. The best times for this treatment is spring and fall when they are most active.
