Box elder bugs are a common household pest found throughout much of North America. They are known for their distinctive appearance and tendency to invade homes in large numbers during the fall months. These bugs are typically black with red or orange markings and have a flat, oval-shaped body that is approximately 1/2 inch in length. Understanding the identification and behavior of box elder bugs is crucial for effective management and prevention of infestations.
Physical Characteristics
Box elder bugs have several distinct physical characteristics that can be used for identification. They have a black body with red or orange stripes that run along their back, as well as red or orange markings on their wings. Their body is typically flat and oval-shaped, with six legs and two antennae. Box elder bugs also have a distinctive red or orange stripe that runs along the edge of their abdomen. Adult box elder bugs are typically between 1⁄2 and 3⁄4 of an inch in length, while nymphs are smaller and lack the distinctive red or orange markings.
Habitat and Behavior
Box elder bugs are typically found in areas where box elder trees are present, as they feed on the seeds and sap of these trees. They are also commonly found in other areas with an abundance of food sources, such as gardens, parks, and backyards. Box elder bugs are known to be attracted to light and can often be found near windows, doors, and other sources of illumination. During the fall months, box elder bugs will often migrate to warm locations such as homes, sheds, and other buildings in search of food and shelter.

| Body Shape | Flat and oval-shaped |
| Size | 1/2 to 3/4 inch in length |

Life Cycle
The life cycle of box elder bugs typically consists of three stages: egg, nymph, and adult. Female box elder bugs will lay their eggs in the spring, typically in areas with an abundance of food sources such as box elder trees. The eggs will hatch into nymphs, which will go through a series of molts as they grow and develop. The nymphs will eventually reach adulthood, at which point they will begin the cycle again. Adult box elder bugs can live for several months, and may overwinter in warm locations such as homes or sheds.
Management and Prevention
There are several steps that can be taken to manage and prevent box elder bug infestations. These include sealing entry points such as cracks and crevices around windows and doors, removing food sources such as box elder trees, and using insecticides to kill box elder bugs that have already entered the home. It’s also important to keep homes clean and free of clutter, as this can help to reduce the attractiveness of the home to box elder bugs.
