How to Kill Ground Wasps – Tips and Tricks

Ground wasps can be a real pain, especially during the warmer months when they are most active. If you are dealing with a ground wasp infestation, then you know just how frustrating and even dangerous it can be. In this article, we will discuss how to kill ground wasps and keep them from coming back.

Finding the Ground Wasp Nest

The first step in killing ground wasps is to locate their nest. This can be tricky, as ground wasps are known to build their nests in a variety of locations. Some common areas to check for ground wasp nests include:

  • Underneath rocks or stones
  • In the ground, particularly in areas with loose soil
  • Inside hollow tree stumps or logs
  • In abandoned animal burrows

Once you have located the ground wasp nest, you can move on to the next step in the process.

Choosing the Right Insecticide

When it comes to killing ground wasps, there are a variety of insecticides on the market that can be effective. However, not all insecticides are created equal. When choosing an insecticide, it is important to read the label carefully and make sure that it is specifically designed to kill ground wasps.

Popular Insecticides for Killing Ground Wasps

  • Pyrethrin
  • Carbaryl
  • Permethrin
  • Bifenthrin

These insecticides can be purchased at most home improvement stores and garden centers. Be sure to follow the instructions carefully when applying the insecticide.

Applying the Insecticide

Once you have chosen the right insecticide, it’s time to apply it to the ground wasp nest. The best time to apply insecticide is either early in the morning or late in the evening, when the ground wasps are less active.

Protective Gear

Before applying the insecticide, it is important to protect yourself. Wear long sleeves, pants, shoes, and gloves to avoid getting stung. You may also want to consider wearing a face mask to protect your nose and mouth from the insecticide.

Applying the Insecticide

Apply the insecticide according to the directions on the label. Most insecticides come in a spray form, which can be easily applied to the nest. Make sure to spray the entire nest thoroughly, as the insecticide needs to come into contact with all of the ground wasps in order to be effective.

Removing the Nest

After you have applied the insecticide, it’s time to remove the ground wasp nest. This is important, as leaving the nest can attract other ground wasps to the area.

Removing the Nest Safely

Wait at least 24 hours after applying the insecticide before attempting to remove the nest. This will ensure that all of the ground wasps have been killed. Use a shovel to carefully dig up the nest, making sure to wear protective gear to avoid getting stung.

Disposing of the Nest

Once you have removed the ground wasp nest, it’s important to dispose of it properly. Place the nest in a trash bag and seal it tightly. Do not compost the nest, as this can attract other insects to the area.
