Dealing with Hidden Wasps Inside Your Home

Sometimes, wasp nests are hidden within the walls, attic, or crawl space of your home. These nests are harder to spot and even harder to deal with. If you suspect you have a hidden nest, here’s how to find it and safely address the problem.

1. Identifying the Nest Location

If you notice an increase in wasp activity around specific areas of your home, check for possible entry points, such as cracks in the siding, gaps around windows, or areas where utility lines enter the house. This could indicate the presence of a nest inside the walls or attic.

2. How to Deal With A Wasp Nest in Your Walls or Attic

If the nest is inside the walls or attic, it’s crucial to locate the exact entry point and treat it with insecticide. If the nest is large or difficult to access, it’s often safer to hire a professional exterminator who can reach the nest without causing damage to your home.

3. Why You Shouldn’t Wait

Nests inside your walls can become a serious issue, especially with yellow jackets, which are more aggressive than wasps. These insects can cause significant damage to your home if they chew through insulation or drywall, and they may even enter your living spaces.

Size

On average, paper wasps in the Pacific Northwest measure one-half to one-and-a-half inches in length.

Color

Paper wasps are very dark brown to black in body color, with yellow markings on their heads and thorax (mid-section), and yellow rings on their abdomens. Their wings are brownish and slightly transparent in appearance.  They are distinct from hornets or yellow jackets – you just need to know what you’re looking for.
