Protect Your Home from Boxelder Bugs & Asian Beetles

There’s something about the first cool days of fall that feels like a welcome change—but for homeowners, it can also signal the beginning of an unwelcome seasonal invasion. Boxelder Bugs and Asian Beetles are preparing for winter, and your home can provide exactly the warm, protected shelter they’re looking for.
As temperatures drop and the autumn sun moves lower in the sky, these pests gather on warm, sun-exposed surfaces, often by the thousands. The south- and west-facing sides of homes are particularly attractive. From there, Boxelder Bugs and Asian Beetles can work their way through surprisingly small openings around windows, doors, siding, vents and other areas of the exterior.
Once inside, they can settle into wall voids and other protected spaces, remaining there through the winter and emerging again when warmer weather returns. That’s where The Mosquito Guy’s Fall Pest Control Program comes in.
Stop Them Before They Get Inside
Rather than waiting until these pests have already invaded your home, The Mosquito Guy takes a proactive approach with a thorough exterior treatment designed to create a protective barrier around your home.
Technicians concentrate on the areas where seasonal pests are most likely to congregate and enter, including:
- South- and west-facing siding, where the afternoon sun creates warm surfaces that attract insects.
- Windows and window frames, including areas where small gaps can provide access to the interior.
- Exterior doors and entryways, which can offer another convenient route indoors.
- Eaves, soffits and other sheltered areas where insects may gather.
- Cracks, crevices and potential entry points around the exterior of the home.
The treatment is applied strategically to the exterior surfaces where these pests are most active, helping reduce the number of insects that reach potential entry points in the first place.
One Fall Treatment. One Simple Fee.
The Mosquito Guy makes seasonal pest prevention simple. The Fall Pest Control Program features a one-time application for a flat fee, giving homeowners an opportunity to address the problem before the insects begin moving indoors.
It’s a preventive approach designed around the seasonal behavior of Boxelder Bugs and Asian Beetles—treating the exterior when and where these pests are looking for a place to spend the winter.
Don’t Wait for the Invasion
Once Boxelder Bugs and Asian Beetles have found their way inside, they can be difficult to deal with. You may not notice them immediately, but as they move through wall spaces and other protected areas, they can eventually appear around windows, ceilings and living spaces.
A little preparation in the fall can help prevent a much bigger nuisance later.
Get ahead of the seasonal invasion with The Mosquito Guy’s Fall Pest Control Program. Contact The Mosquito Guy today to schedule your one-time exterior treatment and protect your home before fall pests start looking for a way inside.
