Every fall, homeowners in Star notice an invasion of small, black-and-red insects clustering on walls, windows, and door frames. These are boxelder bugs, and while they don’t bite or destroy property, they can quickly become a nuisance indoors. Their droppings stain walls, furniture, and fabrics, and once inside, they are difficult to remove. The good news is that with the right approach, you can prevent these pests from taking over your home and yard.
What Are Boxelder Bugs?
Boxelder bugs are half-inch-long insects with distinctive black bodies and red or orange markings along their backs. They feed on seeds and leaves from boxelder, maple, and ash trees. During the warm months, they remain outdoors, but as the temperatures drop in Star, they seek warmth and shelter. That’s when they migrate toward homes, sheds, and garages, where they attempt to overwinter.
Although they don’t chew wood or spread disease, their sheer numbers and the mess they leave behind can cause headaches for homeowners.
Why Boxelder Bugs Invade Homes in Star Seasonal Migration
Boxelder bugs gather in massive swarms in late summer and fall. They crawl into small cracks in siding, gaps around windows, and rooflines. Once inside, they hibernate until spring.
Sunlight and Warmth
South- and west-facing walls are their favorite spots because they soak up the afternoon sun. Homes in Star with exposed siding on these sides often attract the largest swarms.
Local Trees
If you have a boxelder or silver maple tree nearby, you’re far more likely to notice recurring infestations. These trees serve as their primary food source and breeding ground.
Preventing Boxelder Bug Infestations
The best way to manage these pests is to stop them before they get inside. Here are proven prevention methods:
Seal Entry Points
Inspect your home’s foundation, siding, and windows. Seal cracks with caulk, replace damaged weather stripping, and repair torn screens. Even tiny gaps can allow hundreds of bugs to slip inside.
Maintain Your Yard
Keep shrubs trimmed and avoid stacking firewood or debris against the house. If you have boxelder trees near your property, consider consulting an arborist about removal or trimming.
Apply a Home Insect Barrier
A protective treatment applied around the foundation and potential entry points creates an invisible shield. This keeps bugs from gaining access and significantly reduces infestations.
For lasting results, many homeowners turn to professional home pest control services, which provide seasonal treatments and expert protection.
What To Do if Boxelder Bugs Are Already Inside
Once indoors, boxelder bugs are difficult to control without professional help. Crushing them releases a foul odor and can stain surfaces. Instead, try these steps:
- Vacuum them up and empty the bag outdoors immediately.
- Avoid using indoor sprays—they are rarely effective and may create more problems.
- Reduce light sources at night around windows and doors, since light attracts them.
If you’re seeing dozens or even hundreds inside, it’s a clear sign that your home has multiple entry points that need to be addressed.
When to Call for Professional Pest Control in Star
While DIY steps can help, most homeowners experience boxelder bugs year after year. This is because once they establish an overwintering site, they return to the same spot each season. A professional service can:
- Identify and seal common entry points
- Apply safe, effective treatments around your home
- Provide ongoing seasonal protection to prevent re infestation
For fast relief, scheduling a local pest control service ensures your home is treated thoroughly and correctly.
Boxelder Bugs and Businesses
These insects don’t just bother homeowners. Businesses in Star, especially those with large south-facing windows, also struggle with swarms. A professional commercial pest control program is the best way to ensure a clean, pest-free environment for both employees and customers.
FAQs About Boxelder Bugs in Star are boxelder bugs harmful?
No, they don’t bite, sting, or damage buildings, but they can stain walls, curtains, and upholstery with their droppings.
Do they come back every year?
Yes. Boxelder bugs are seasonal and will return to the same overwintering locations each fall unless treated.
Can removing trees stop them?
Removing female boxelder trees helps reduce populations, but since they can fly from nearby areas, prevention and treatment are still necessary.

They remain active until cold weather drives them fully indoors, where they remain until spring. Without control measures, they’ll return the following year.
