Fall in New Jersey brings a beautiful tapestry of changing leaves and cooler temperatures. However, it also brings an unwanted visitor to many homes: the boxelder bug. These pests are notorious for seeking refuge indoors as the weather cools, creating a nuisance for homeowners. Therefore, many search for answers to keeping boxelder bugs out of their homes and businesses.
In this fall guide, we will explore the behavior of boxelder bugs, why they invade homes during the fall, and practical strategies to keep them out. By the end of this article, you will be equipped with the knowledge to protect your home and enjoy a pest-free fall season.
Understanding Boxelder Bugs

Boxelder bugs, scientifically known as Boisea trivittata, are black with distinctive red or orange markings on their back. They are about half an inch long and have a flattened, elongated shape. These insects are primarily found on boxelder trees and other maples and ash trees, feeding on seeds, leaves, and flowers.
While they do not pose a significant threat to plants, they can become a major nuisance when they enter homes in large numbers.
Why Boxelder Bugs Invade Homes in the Fall
During the warmer months, boxelder bugs remain outdoors, feeding and breeding on trees. However, as temperatures drop in the fall, they seek warm and sheltered places to overwinter. Your home provides the perfect refuge, offering warmth and protection from the harsh winter conditions.
Boxelder bugs are attracted to the sunny sides of buildings. They often congregate on exterior walls before finding their way inside through small cracks and openings.
Signs of a Boxelder Bug Infestation
Before delving into prevention methods, it is essential to recognize the signs of a boxelder bug infestation. Some common indicators include:
- Clusters of Bugs: You may notice groups of boxelder bugs on the sunny sides of your home, particularly near windows, doors, and vents.
- Indoor Sightings: Finding boxelder bugs inside your home, especially near windows and light fixtures, is a clear sign of an infestation.
- Excrement Stains: Boxelder bugs excrete a reddish-brown liquid that can stain walls, curtains, and furniture.
Preventative Measures to Keeping Boxelder Bugs Out
Preventing boxelder bugs from entering your home requires sealing entry points, reducing attractants, and employing natural and chemical deterrents. Here are some effective strategies:
- Seal Entry Points:
- Inspect your home for any gaps, cracks, and holes around windows, doors, siding, and utility openings. Use weatherstripping or caulk to seal these entry points.
- Repair or replace damaged screens on windows and doors to prevent bugs from entering.
- Install door sweeps on exterior doors to eliminate gaps at the bottom.
- Reduce Attractants:
- Boxelder bugs are attracted to boxelder trees and other maples. If feasible, consider removing these trees from your property, especially if they are close to your home.
- Keep your yard clean and debris-free, such as fallen leaves and branches, which can attract boxelder bugs.
- Natural Deterrents:
- Create a homemade spray using water and a few drops of dish soap. Spray this mixture directly on boxelder bugs to kill them on contact.
- Essential oils like lavender, eucalyptus, and tea tree oil can be natural repellents. Mix a few drops with water and spray around entry points and areas where boxelder bugs are commonly found.
- Physical Barriers:
- Install mesh screens over vents and chimneys to prevent boxelder bugs from entering these openings.
- Use fine mesh netting to cover outdoor air conditioning units and other equipment that could provide entry points for bugs.
- Chemical Deterrents:
- Insecticidal sprays labeled for boxelder bug control can be effective when applied to exterior walls and entry points. Follow the manufacturer’s instructions carefully.
- Diatomaceous earth, a natural powder, can be sprinkled around entry points. It dehydrates and kills insects that come into contact with it.
(Please note that you must exercise extra caution with any chemical deterrent; many can be dangerous to humans and pets.)
Dealing with Boxelder Bugs Inside Your Home

Some boxelder bugs may still find their way inside despite your best efforts. Here are steps to manage them:
- Vacuuming:
- A vacuum cleaner removes boxelder bugs from walls, windows, and other surfaces. Please dispose of the vacuum bag or contents immediately to prevent them from escaping.
- Trap and Release:
- Create simple traps using a shallow dish filled with soapy water and a light source. Boxelder bugs are attracted to light and will drown in the soapy water.
- Exclusion:
- If you find boxelder bugs in a specific room, close the door to prevent them from spreading to other parts of the house. Use a vacuum or soapy water to remove them.
- Pesticides:
- If the infestation is severe, consider using indoor insecticidal sprays labeled for boxelder bugs. Be sure to follow safety guidelines and keep the area well-ventilated. (Note: pesticides can be harmful to humans and pets)
