Boxelder bugs (Boisea trivittata) are common household pests that can cause infestations in homes, businesses, and other structures. They are known for their reddish-black bodies with three orange stripes across their wings, and they typically emerge in large numbers during the fall when they seek shelter from the cold.
Causes of Boxelder Bug Infestations
These bugs are attracted to boxelder trees, where they feed on the sap of the seeds. When these trees are located near buildings, the bugs can enter through cracks, gaps, or other openings in the exterior.
Effective Control Methods
1. Seal Entry Points
Inspect the exterior of your home for any cracks or gaps around windows, doors, pipes, or vents. Seal these openings with caulk, weatherstripping, or expanding foam to prevent boxelder bugs from entering.
Sealing Method | Materials |
---|---|
Caulk | Silicone caulk, latex caulk |
Weatherstripping | Foam tape, rubber gaskets |
Expanding Foam | Polyurethane foam |
2. Remove Boxelder Trees
If possible, remove any boxelder trees located near your property. This will eliminate the primary food source for these pests.
3. Chemical Control
Insecticides labeled for boxelder bug control can be used to kill these pests on contact. Apply the insecticide around entry points and areas where boxelder bugs are likely to congregate.
Insecticide Type | Active Ingredient |
---|---|
Pyrethroids | Permethrin, bifenthrin |
Neonicotinoids | Imidacloprid, acetamiprid |
Carbamates | Carbaryl, propoxur |
4. Vacuuming and Removal
Regularly vacuum your home, paying close attention to areas where boxelder bugs may be hiding, such as corners, closets, and under furniture. Dispose of the vacuum bag or empty the canister to prevent re-infestation.
5. Home Remedies
Some home remedies, such as peppermint oil or vinegar, have been anecdotally reported to repel boxelder bugs. While they may not be as effective as chemical control methods, they can provide a temporary deterrent.

Boxelder Bug Infestations
Boxelder bugs, known for their black and red markings, are common household pests during the fall. They typically congregate outside homes and other structures, seeking shelter from the cold. Infestations can become severe, with thousands of bugs accumulating on walls, windows, and doors.
Boxelder bugs do not bite or transmit diseases, but they can be a nuisance. They may enter homes through cracks and crevices, leaving behind stains on curtains, furniture, and walls. Additionally, their strong odor can be unpleasant.
To prevent infestations, seal up potential entry points around windows, doors, and pipes. Chemical insecticides can also be used to control infestations, but should be applied carefully to avoid harming beneficial insects. Natural remedies, such as repellents containing peppermint, cinnamon, or vinegar, can also be effective.
Boxelder Bug Traps
Boxelder bugs are common pests that can be difficult to control. They are attracted to the warmth of homes in the fall and can become a nuisance inside. Boxelder bug traps can be an effective way to reduce the number of bugs entering your home.
These traps are typically made of a plastic or metal frame with a sticky surface. The bugs are attracted to the sticky surface and become trapped. Traps can be placed in areas where boxelder bugs are likely to enter, such as near windows and doors.
Boxelder bug traps are an inexpensive and effective way to reduce the number of bugs entering your home. They are easy to use and can be placed in any area where boxelder bugs are a problem.
Boxelder Bug Life Cycle
- Eggs: Female boxelder bugs lay clusters of eggs during the fall on the underside of leaves or other protected surfaces. Each cluster contains 20-30 eggs.
- Nymphs: After winter, the eggs hatch in the spring, and the newly emerged nymphs feed on the sap from嫩芽. Nymphs go through five instars, increasing in size with each molt.
- Adults: Once the nymphs reach maturity, they develop wings and become adults. Adults are about 1/2 inch long and have a reddish-brown body with black and orange markings.
- Reproduction: Adult boxelder bugs mate in the summer, and the females lay eggs that will hatch the following spring.
Boxelder Bug Bite
Boxelder bugs are not known to bite humans. They Feed on boxelder trees and can be a nuisance when they enter homes in large numbers during the fall and spring. Their bites are not venomous, but they may cause minor skin irritation or allergic reactions in some people.
Boxelder Bug Eggs
Boxelder bug eggs are small, black or brown, and oval-shaped. They are about 1 millimeter long and laid in clusters of 40-50 eggs on the underside of leaves. The eggs hatch in about 10 days, and the nymphs feed on the leaves of boxelder, maple, and ash trees. Nymphs are red or orange with black markings, and they have a distinctive white band across their backs. They molt five times before reaching adulthood, and they can become a nuisance in large numbers.
Boxelder Bug Nests
Boxelder bugs typically build their nests in sheltered areas such as under loose bark, in crevices, or in hollow tree trunks. The nests are often located near sources of food, such as boxelder trees. Nests typically consist of a cluster of brown or gray eggs that are laid in a single layer. The eggs hatch into nymphs that resemble the adults, but are smaller and wingless. The nymphs feed on the leaves of boxelder trees and other plants.
Boxelder Bug Poison
Boxelder bugs do not produce venom or toxins and are not poisonous to humans or pets. They do release a foul-smelling odor when crushed or threatened, but this odor is not harmful and poses no health risks.
Boxelder Bug Pheromone
Boxelder bugs release a pheromone that attracts other bugs to their overwintering sites. This pheromone is produced by the scent glands of the bugs and is released when they aggregate in large numbers. The pheromone helps the bugs to locate suitable overwintering sites and to form large aggregations.
The pheromone is a complex mixture of chemicals, including hydrocarbons, ketones, and aldehydes. The major component of the pheromone is a hydrocarbon called (E)-2-hexenal. This chemical has been shown to be attractive to boxelder bugs at very low concentrations.
The pheromone is released from the scent glands of the bugs in a pulsatile manner. The bugs release the pheromone more frequently when they are in close proximity to other bugs. This helps to create a strong pheromone plume that can attract other bugs from a distance.
The pheromone is an important part of the boxelder bug’s life cycle. It helps the bugs to locate suitable overwintering sites and to form large aggregations. This helps to ensure the survival of the bugs over the winter months.
