Red and Black Bugs Around Your Home? How to Identify and Get Rid of Boxelder Bugs

Have you noticed large numbers of red and black bugs gathering around your windows, siding, doors, or exterior walls? Many homeowners throughout Ontario and the Greater Toronto Area become concerned when they suddenly see clusters of these insects on their property.

In most cases, these red and black bugs are boxelder bugs, a common nuisance pest that frequently invades homes during the fall and spring seasons. While they do not bite or cause structural damage, they can become a major annoyance when large populations gather around your property.

If you're dealing with red and black bugs around your home, understanding what attracts them and how to prevent infestations can help keep your property pest-free.

What Are Boxelder Bugs?

Boxelder bugs are easily identified by their distinctive black bodies with bright red or orange markings along their wings and thorax.

Adult boxelder bugs typically measure about half an inch in length and are commonly found on:

• Exterior walls
• Window frames
• Doors
• Decks and patios
• Trees and shrubs
• Garages and sheds

These insects are especially attracted to sunny areas where they gather in large groups to absorb heat.

Why Are Red and Black Bugs Invading My Home?

Many homeowners become alarmed when they suddenly notice hundreds of red and black bugs appearing on the exterior of their home.

Boxelder bugs are attracted to properties for several reasons:

Warm Surfaces

During cooler months, boxelder bugs seek warmth and frequently gather on south-facing walls and windows that receive direct sunlight.

Shelter for Winter

As temperatures begin to drop, boxelder bugs look for protected areas where they can overwinter. Small cracks and openings around windows, doors, vents, and foundations often provide easy access.

Nearby Trees

Boxelder bugs feed primarily on seeds from boxelder, maple, and ash trees. Homes located near these trees often experience higher levels of activity.

Are Boxelder Bugs Dangerous?

One of the most common questions homeowners ask is whether these red and black bugs pose a threat.

Fortunately, boxelder bugs are considered nuisance pests rather than dangerous insects.

They do not:

• Bite humans
• Sting people or pets
• Damage furniture
• Destroy structural wood
• Reproduce indoors

However, large infestations can create several problems.

Staining

When crushed, boxelder bugs can leave reddish stains on walls, curtains, carpets, and furniture.

Unpleasant Odor

Like many nuisance insects, boxelder bugs release a foul-smelling defensive odor when disturbed.

Indoor Infestations

Once inside, these pests may emerge throughout the winter and become a persistent nuisance around windows and living spaces.

Signs of a Boxelder Bug Infestation

You may have a boxelder bug problem if you notice:

• Large groups of red and black bugs on exterior walls
• Insects gathering around sunny windows
• Bugs appearing inside during winter months
• Increased activity near maple or boxelder trees
• Clusters of insects near attic vents and siding

Early identification can help prevent larger infestations from developing.

How to Get Rid of Red and Black Bugs

If you're dealing with a boxelder bug infestation, there are several effective control methods available.

Seal Entry Points

Inspect your property for:

• Foundation cracks
• Gaps around windows
• Openings around utility lines
• Damaged weather stripping
• Vent openings

Sealing these areas can significantly reduce indoor invasions.

Reduce Attractants

Homeowners should remove potential shelter sites around the property, including:

• Leaf piles
• Wood piles
• Excessive vegetation near structures

Keeping outdoor areas clean helps make your property less attractive to pests.

Regular Exterior Inspections

Routine inspections allow homeowners to identify pest activity before infestations become severe.
