Yellow Jacket Pest Control Products

All wasps will defend their nests, but the Yellow Jackets and hornets are the most aggressive. They can be distinguished from bees by their thin "waists." Bees are thick-wasted. They fold their wings lengthwise when at rest. Like all wasps, yellow jackets prey on a variety of insects and other arthropods. Yellow jackets will also forage on foods that people eat, especially sweets and meats.

They are considered beneficial insects, eating other insects. The yellow jacket colony will remain active for only one summer, after which the queens will fly away to start more colonies. The remaining ones, die at the end of the summer, the nest is not reused.


Size: 5/8 to 1 inch

Color: Black and Yellow or black and white

They have a thin waist.


They usually nest in the ground, but will nest also in railroad ties, wall voids, and other above ground locations. In the spring, most yellow jackets will feed on insects. Many homeowners see"bees" flying around their hedges. These "bees" are usually yellow jackets and are there to eat insects on the foliage. Spraying the hedges with an appropriate insecticide will kill the food source of the yellow jackets, and they will soon leave the area.

In the fall, wasp colonies have come the largest size, and foraging workers may be a serious nuisance as they search for food people eat or discarded food.

If a colony is disturbed, they can become very aggressive and sting. For most a sting is temporary, but painful, but for allergic individuals as single sting may result in a serious reaction, requiring medical treatment.


Sanitation( to eliminate possible food sources) is important to reduce build up of foraging population during the summer to mid autumn .

Trash containers should be kept closed and open containers should be emptied regularly.

Nests should be located during the day, so you can see the workers entering and exiting all day. Mark the entry points. Treat at night only when it is dark.

  • Any treatments should be done at night, because they are all in the nest. They don't see well at night and your chances of being stung are greatly reduced.

    Treat the nest with a pyrethrum aerosols such as PT 565 Plus or CB Extra  

    Pyrethrum forms a gas which will fill the cavity, killing the yellow jackets.

  • Check the nest the following day, to see if the yellow jackets are indeed dead by lack of activity.
    It may be necessary to repeat treatment.

    Wait unil the aerosol is dry then dust in the opening with evergreenEvergreen Dust  

     d fense D-Fense Dust

    These dusts will leave a residue to continue to kill for months and eliminate any hatch outs Delta Dust is slower acting.

    With a little care and caution, yellow jackets can be easily and safely eliminated.


    1. Spray opening at night with pyrethrin aerosol
    2. Wait until aerosol is dry(10-15 minutes), then dust opening with Evergreen Dust(faster kill with the pyrethrin aerosol)or

    3. D Fense Dust (1 week-slower kill with pyrethrin aerosol

    For complete results use Walt's Yellow Jacket Kit (CB 80 and Evergreen Dust and duster)

    • A further recommendation would be to use a trap with a lure like fruit juice or meat like :  yellow jacket trap
      YELLOW JACKET TRAP by Advantage, which would be helpful if you can't find the location of the nests.

      Place the trap away from where you are going to be, you want to lure them in the trap.
      This trap is very helpful during picnics, and cook outs , drawing them away from you.
      The traps come with a lure, however meat works best in early in the season and fruit juice works well later in the summer and fall months.
