How to Get Rid of Boxelder Bugs in West Denver

To eliminate boxelder bugs in West Denver, you need professional perimeter treatment that targets them before they enter your home. In order to do this, Mosquito Squad of West Denver's Home Shield service treats entry points, seals gaps around foundations and windows, and creates a protective barrier that stops boxelder bugs from invading indoor spaces.

This is especially useful during fall when they're actively seeking shelter. Our treatments work because we go after the problem at the source. That means blocking their access rather than just eliminating the ones that already made it inside.

What Are Boxelder Bugs?

Boxelder bugs are black insects with distinctive red or orange markings on their backs. They're about half an inch long and get their name from boxelder trees, where they feed and breed during warmer months.

Luckily, boxelder bugs are not dangerous. They don't bite, sting, or cause structural damage like termites. But they are incredibly annoying.

During spring and summer, boxelder bugs stay outside feeding on boxelder tree seeds, maple trees, and ash trees. You might see a few here and there, but they're not typically a problem. That changes completely when fall arrives.

Why Boxelder Bugs Are So Bad in West Denver During Fall

West Denver has plenty of factors that make boxelder bug invasions worse here than in many other areas. First, we've got plenty of boxelder, maple, and ash trees throughout the region. These are exactly the trees these bugs prefer. It also doesn’t help that our fall weather patterns are ideal for boxelder bug activity.

As temperatures start dropping in September and October, boxelder bugs go into panic mode. It’s then that they start looking for warm places to spend the winter. This makes your home look very appealing. They congregate on south and west-facing walls where the sun warms the exterior, then search for any crack or gap to squeeze through.

The problem in West Denver is that we get those warm fall afternoons that bring boxelder bugs out in huge numbers, followed by cold nights that make them desperate to get indoors. This temperature swing creates waves of invasions throughout autumn.

Once boxelder bugs find a good overwintering spot, they leave behind pheromone trails that attract more bugs to the same location. That's why homes that had boxelder bug problems last year almost always get them again. That is, unless you take action to break the cycle.

What Happens When Boxelder Bugs Get Inside

Boxelder bugs don't reproduce indoors or cause damage, but they create other problems. Hundreds or thousands of bugs clustering on your walls, windows, and curtains is disturbing. They leave behind reddish stains on fabrics and surfaces from their excrement. And when they're disturbed or crushed, they emit an unpleasant odor.

Worse, boxelder bugs that overwinter in your walls will emerge in spring when temperatures warm up. You'll find them crawling around windows and light fixtures, trying to get back outside. Some homeowners deal with boxelder bugs appearing indoors for months.

What Doesn't Work Against Boxelder Bugs

Vacuuming up boxelder bugs you see indoors only addresses the ones that already made it in. Sealing up cracks yourself helps, but you'll miss entry points you didn't know existed. Store-bought sprays might take out individual bugs, but they don't prevent new ones from entering.

The biggest mistake is waiting until you see them inside to take action. By then, hundreds more are already in your home preparing to overwinter.

How Professional Treatment Helps Eliminate Boxelder Bugs

Mosquito Squad of West Denver's Home Shield service stops boxelder bugs before they become an indoor problem. We treat the exterior of your home with particular focus on south and west-facing walls where boxelder bugs congregate. Our treatments target entry points around windows, doors, foundations, utility penetrations, and anywhere bugs might squeeze through.

We also seal gaps and cracks that boxelder bugs use to access your home. The combination of treatment and sealing creates a barrier that stops invasions before they start.

Timing matters. Late summer and early fall—before the first cold snap—is when you want treatment applied. This catches boxelder bugs before they start their migration indoors.
