Nuisance and household pests-Wasp (yellowjacket)

Vespula spp.

Pest description and damage Bee-like insects with yellow and black, or white and black, bands on abdomen.


Some professionals in the PNW collect wasps to be used in the manufacture of allergy injections. Once a nest has been treated, it cannot be collected for this purpose. Before attempting to treat nests on your own, contact a pest control professional to inquire whether a collector is in your area. Wasp nests should be treated in evening when wasps are less active with a pesticide formulated specifically for wasp nests. Do not treat nests with any household chemicals or common fuels such as bleach, gasoline, or diesel; these products are more toxic than most labeled pesticides. Commercial pest control operators should be contracted to do this work if you are subject to severe reactions to wasp, hornet, or yellowjacket stings.

Purchasing Pest Management Services

Do not be alarmed if you learn or suspect that structural pests may be attacking your home; it will not collapse or be destroyed. Pest management should be considered merely as another repair that may be necessary to maintain your house in sound structural condition.

Do not rush into purchasing pest management services. Damage usually develops slowly. Presence of these pests in a house seldom constitutes an emergency. Any additional damage done over a few weeks or even a few months makes little difference. You always have ample time to purchase service wisely and at your convenience.

Purchase service from a reliable firm. Select a pest management service with the same care and discrimination you would exercise in choosing any other service. Deal only with reliable firms that have an established place of business.

Questions to ask before hiring a pest management professional

  • Are you properly licensed with the state department of agriculture? Ask to see their license.
  • Can you provide a list of references? Most companies will be happy to share their success stories with you.
  • Will I receive a written report of your findings, proposed treatment, and costs? Obtain at least three estimates and compare services.
  • What are the terms of your service agreement? Understand the provider's obligations and yours, too.
