Why Do I Have Boxelder Bugs When My Neighbors Do Not?

If you’re experiencing a boxelder bug invasion, but your neighbors are not, there could be a few reasons.

It might be the trees on your property, the amount of sunlight your home receives, and even the available shelter. And no, it doesn’t mean your neighbors are better housekeepers or that you’ve even done anything wrong.

Boxelder bugs can come together in alarmingly large numbers around one property while barely making an appearance next door. Their preferred food sources and overwintering habits help explain why.

Do Certain Trees Attract More Boxelder Bugs Than Others?

Definitely. As you might imagine, boxelder bugs primarily feed on seeds produced by female boxelder trees. They’re additionally drawn to maple and ash trees. If your property has a female boxelder tree, or one nearby, you can encounter considerably more bugs than someone with landscaping that doesn’t include their natural food sources.

Boxelder bugs will fly between properties. So, you don’t necessarily need a boxelder tree in your yard to experience a problem.

How Does Sunlight Make a Difference?

Boxelder bugs are naturally drawn to warm, sunlit exterior walls, and especially so during cooler months. South-facing and west-facing walls that are exposed to afternoon sunlight provide highly favorable basking locations for these bugs.

If your home receives more direct sunlight than your next-door neighbor’s, you might find that it attracts large congregations of boxelder bugs, even if your homes are only a few yards apart.

As temperatures drop in the fall, these bugs begin seeking places to spend winter. Therefore, they might gather around siding, window frames, doorways, and foundations before finding their way inside through accessible cracks and crevices.

On warm winter days, boxelder bugs will sometimes reemerge from their overwintering spot to enjoy a warm exterior wall.

Are You Sure They’re Boxelder Bugs?

Here’s the thing about boxelder bugs: here in Central Texas, they have a lookalike. Red-shouldered bugs are black and red, like boxelder bugs. And they frequently become nuisance pests around Texas homes.

What’s more, these doppelganger insects have similar overwintering habits. While they are occasionally found feeding on or around maple, ash, and some fruit trees, red-shouldered bugs are commonly attracted to western soapberry, Chinaberry, and goldenrain trees.

This is just to say that correctly identifying whether you have boxelder bugs or redshouldered bugs will help explain why one property might attract more than another.

How Can You Keep Boxelder Bugs Away from Your House?

Though boxelder bugs will not generally cause structural damage to your home, they can be annoying, especially when they show up in large numbers and gather around your windows and doors. Additionally, their droppings can stain certain surfaces.

Keeping them away from your home starts with some commonsense home maintenance. This includes sealing accessible cracks, repairing gaps around window screens, and replacing damaged seals and weatherstripping on exterior doors. It’s also smart to remove accumulated leaves and other yard debris that might serve as shelter for boxelder bugs.

And because they can cause staining, we recommend vacuuming boxelder bugs inside your home rather than crushing them.
