Understanding Yellow Jackets in Lancaster PA

Yellow jackets are common stinging insects in Pennsylvania, thriving in the temperate climate of Lancaster County.

Unlike bees, yellow jackets are wasps that can sting multiple times and become highly aggressive when their nest is threatened. In urban and suburban areas like Lancaster, they often build nests in hidden spots, such as:

  • Wall voids and cavities
  • Attics and eaves
  • Ground burrows near homes

A yellow jacket nest in wall can grow rapidly, housing thousands of workers by late summer.

Homeowners in Lancaster PA might notice increased activity around entry points, buzzing sounds from walls, or even stings indoors if the nest expands.

How did the homeowner know they had yellow jackets in the wall?

The homeowner was seeing yellow jackets coming and going from the roof line where the dormer roof meets the main roof of the home.

In the spare bedroom directly under the area where the yellow jackets were seen entering the roof line, the homeowners could hear the yellow jackets in the wall.

Yellow jackets in the wall can sound like scratching and/or buzzing.

Our successful Yellow Jacket Nest Removal in Lancaster PA

When we arrived, we could see the yellow jackets coming and going from the roof line. As we inspected inside the spare room, we could see the soft spot in the wall where we suspected the nest was located.

Putting a hand on the soft spot on the wall, it felt warm to the touch. After putting on our protective bee suit and prepping the work area with tarps, we created a small hole into the wall and injected a pressurized aerosol into the wall void.

The nest immediately came to life, and we could hear a loud and continuous buzzing sound coming from the wall. As the sound started to die down as more and more yellow jackets were killed, we began to open more of the damaged drywall.

The drywall was very thin due to the yellow jackets chewing at the back side of the drywall. This makes the drywall super soft and very easy to cut through and remove. As more of the drywall is removed, we continue to inject the aerosol PT PI into the wall void. This is because as more of the area is exposed, the PT PI can reach more places into the wall void.

Once the sound inside the wall quieted down, we began to remove the combs of the nest. In this case, the comb of the nest was removed in complete pieces.

This is not always the case as sometimes the soft nesting material breaks apart during the treatment and removal process.

The Yellow Jacket nest is treated, now what?

Once the nest and nesting material was removed, we taped off the openings in the drywall so no new yellow jackets could enter the room.

This client requested that we not use a residual chemical in the wall void. This will result in having a few straggling yellow jackets in the wall void but they will not last long.

These remaining yellow jackets will not be able to rebuild the nest and will eventually die off. After the nest was treated and removed and the area taped off, we cleaned up and vacuumed the area.

This leaves a clean appearance and only leaves the homeowner with the job of hiring a drywall professional to patch up the area.
