Understanding Boxelder Bugs in Wisconsin

Boxelder bugs are common pests in Wisconsin, known for their distinctive black and red markings and their tendency to invade homes and buildings in large numbers, especially during the fall. Understanding where they are typically found, what attracts them, and why they are unsuitable for indoor environments is essential for effective management and prevention.

Characteristics and Habitats of Boxelder Bugs

Boxelder bugs are about half an inch long and are easily identifiable by their black bodies with red or orange markings on their wings and thorax. They primarily feed on the seeds of boxelder trees, but they can also be found on maple and ash trees.

Boxelder bugs are typically found in:

Outdoors:

Boxelder Trees: These bugs are most commonly found on or near boxelder trees, feeding on the seeds and leaves.

Maple and Ash Trees: They can also be found on these trees, although they prefer boxelders.

Gardens and Yards: During the warmer months, boxelder bugs can be seen congregating in gardens and yards, especially near their food sources.

Indoors:

Warm, Sunny Sides of Buildings: Boxelder bugs are attracted to the sunny sides of buildings where they can bask in the warmth.

Cracks and Crevices: As temperatures drop in the fall, they seek shelter in cracks and crevices of homes and buildings to overwinter.

Attics and Wall Voids: They often find their way into attics, wall voids, and other hidden areas inside buildings.

Attractions in Homes and Buildings

Boxelder bugs are attracted to homes and buildings for several reasons:

Warmth: As cold weather approaches, boxelder bugs seek out warm places to overwinter, making homes and buildings ideal shelters.

Sunlight: They are drawn to sunny areas of buildings where they can gather warmth.

Entry Points: Small cracks and gaps around windows, doors, and foundations provide easy access for boxelder bugs to enter buildings.

Why Boxelder Bugs Are Not Suitable for Homes and Buildings

While boxelder bugs do not cause significant structural damage or pose serious health risks, their presence in homes and buildings is undesirable for several reasons:

Nuisance:

Large Numbers: Boxelder bugs often invade in large numbers, which can be overwhelming and unsettling for homeowners.

Odor and Stains: When crushed, boxelder bugs release a foul odor and can leave red stains on surfaces, including walls, furniture, and curtains.

Allergic Reactions:

Skin Irritation: Some individuals may experience skin irritation or allergic reactions from contact with boxelder bugs.

Indoor Activity:

Activity During Winter: Although they enter homes to overwinter and are typically dormant, warm indoor temperatures can cause them to become active, leading to sightings throughout the winter months.

Prevention and Control

Preventing and controlling boxelder bug infestations involves several key strategies:

Seal Entry Points: Inspect and seal cracks, gaps, and openings around windows, doors, and foundations to prevent boxelder bugs from entering.

Proper Landscaping: Reduce the number of boxelder, maple, and ash trees near your home to decrease the food sources for these bugs.

Regular Cleaning: Vacuum up any boxelder bugs that find their way inside to prevent staining and odor.

Exterior Treatments: Apply insecticides to the exterior walls of your home in the fall to deter boxelder bugs from congregating and entering.
