Most homeowners are surprised to learn that yellow jackets don’t just build nests in the ground or trees; they can also nest *inside* your home. And yes, they’re fully capable of chewing through drywall to get in (or out). At Commonwealth Pest Management, we’ve already responded to multiple calls this season for yellow jackets breaking through ceilings, walls, and attic spaces.

Why Do Yellow Jackets Chew Through Drywall?

Yellow jackets are aggressive defenders of their nests. If a nest forms in a wall void or ceiling cavity, they may chew through the drywall to expand the nest or escape. This typically happens late in the season as the colony grows larger and becomes more active, especially in August and September.

Signs You Might Have a Nest Inside Your Walls

• Constant buzzing or humming from a single spot in the wall or ceiling
• Yellow jackets appearing inside your home with no clear entry point
• Drywall that looks soft, damaged, or discolored
• Visible holes or yellow jackets emerging from small wall openings
• Aggressive behavior near the area; they may sting if disturbed

What to Do (and What Not to Do)

🚫 Don’t attempt to spray or seal the hole yourself. This can trap the yellow jackets and drive them deeper into your home, or cause them to chew new exit routes.

✅ Do call a licensed pest control professional. At Commonwealth Pest Management, we use safe, effective treatment methods to neutralize the nest, identify all access points, and prevent reinfestation.

If you hear buzzing in the walls or see yellow jackets emerging indoors, don’t wait. These stinging insects can be dangerous, especially in enclosed spaces.
