Pest Control for Yellow Jackets & Wasps

Professional Pest Control for Wasps & Yellow Jackets

The yellow jacket is the most troublesome wasp in the Tacoma, Seattle, Everett, Bellingham and Wenatchee areas.  Yellow jackets are nasty in two ways:

  1. How they aggressively defend their nest often causing many stings, injuring anyone that stumbles upon them.
  2. The other way is how they aggress themselves onto our food, especially when barbequing or picnicking.

All wasp stings are painful and can be debilitating if stung many times or in the case of allergies.  Bees have barbs on their stingers only allowing them to sting once, but wasps—including yellow jackets—can sting multiple times.

There are two major types of yellow jackets and they each make two different kinds of nests:

  1. Those that nest in the ground and other cavities—usually within an abandoned rodent hole; in a hollow stump, post or log; or within the wall or other void of a home. Sometimes they find a small cavity in a rockery or beneath a sidewalk and excavate it further so their colony can fit.
  2. And those that make hanging nests within bushes, from tree limbs, or under porch or roof eaves of a home or business. In this case they can easily rearrange the layers of paper they make to expand the nest. They can get quite large.

Ground nests are often painfully discovered by walking over the nest, which poses a particular threat to pets and children.  Homeowners or workers are often shocked to find yellow jacket ground nests when mowing grass or when clearing brush and debris.

When yellow jackets nest in the wall void of a home, or in the attic just above the ceiling, they pose a unique threat—they are only ½” from entering your home in large numbers. Yellow jackets excavate these areas of insulation and so forth as their colony expands in size and they are known to scratch on the interior of the Sheetrock until they punch through.  Occasionally, yellow jacket colonies become exposed to the living space of home and families have to flee.

Yellow Jacket workers die each fall and the nest is abandoned.  But before the colony has sent out dozens of fertilized females to become future queens the next spring.

Other types of wasps are mud daubers and ‘polestes.’  Mud daubers aren’t social wasps and make small nests out of mud that amount to elongated mud tubes in which their larvae hatch and grow.  Polestes are a social wasp that nest in small numbers on a small umbrella-shaped paper nest of cells.  Both pack a ferocious sting, however, they are far less aggressive than yellow jackets.
