Box Elder Bugs: Identification, Behavior, and Control Methods

Box elder bugs (Boisea trivittata) are common pests that can invade homes and gardens, causing annoyance and frustration. In this article, we will explore the identification, behavior, and control methods for these insects. Additionally, we will address some frequently asked questions about box elder bugs.

Identification:
Box elder bugs are medium-sized insects, measuring approximately half an inch in length. They have a distinctive appearance, featuring a black body with red stripes on the wings. The wings are flat and lie flat on the back when at rest. Another identifying characteristic is the presence of a long, slender proboscis used for feeding. Nymphs are smaller and have a red coloration.

Behavior:
Box elder bugs are primarily found in North America, particularly in the eastern and western regions. They get their name from their preference for box elder trees (Acer negundo), although they can also be found on other deciduous trees such as maple, ash, and cherry. During the warmer months, box elder bugs feed on the leaves, flowers, and seeds of these trees, but they do not cause significant damage. However, as fall approaches, they begin to search for overwintering sites, which often leads them to invade homes.

In late summer or early fall, box elder bugs start congregating on the sunny sides of buildings and trees. They enter cracks and crevices, seeking shelter for the winter. Once inside, they remain inactive, often hiding in wall voids, attics, and other protected areas. When temperatures rise in the spring, box elder bugs emerge from their hiding places and move outdoors to mate and lay eggs. They are not known to reproduce indoors.

Control Methods:
Preventing box elder bug infestations starts with exterior maintenance. Here are some control methods to consider:

1. Seal entry points: Inspect your home for gaps, cracks, and other openings that box elder bugs can use to enter. Seal these entry points with caulk or weather stripping.

2. Repair screens: Ensure that window screens are in good condition, as box elder bugs can enter through damaged screens.

3. Remove hiding spots: Trim overhanging branches and shrubs near your home to reduce potential hiding spots for box elder bugs.

4. Vacuum or sweep: If box elder bugs are already inside your home, use a vacuum cleaner or broom to remove them. Remember to empty the vacuum bag or dispose of the collected bugs far away from your home to prevent re-infestation.

5. Insecticides: If necessary, consider using insecticides labeled for box elder bug control. Follow the instructions carefully and apply the product to the exterior of your home where box elder bugs are congregating.
