The most effective method of getting rid of wasps is to get rid of the nest. Traps will not always work and are more likely to kill off beneficial insects than the irritating ones. Be very careful when trying any of these methods. Keep children and pets well away from the area. There are two types of nests wasps can build: above ground and underground.

    Above Ground Nests

  1. 1

    Plan to get rid of the wasp nest either before dawn or after dusk. Wasps are most active during the day when it is warm. At night, the wasps will be slower to react.

  2. 2

    Purchase a can of wasp remover.

  3. 3

    Locate the nest. You will need to keep children and pets away from this location for a short time after you spray, so plan accordingly.

  4. 4

    Put on several layers of old clothes, gloves, a hat and eye protection.

  5. 5

    Take a position near the nest, but not directly underneath it. Be prepared to quickly escape the area after you spray.

  6. 6

    Spray the poison at the nest. Make sure it is thoroughly covered.

  7. 7

    Leave the area immediately and avoid the area for several hours.

  8. 8

    Return and watch the nest for any activity. If there is activity, repeat Steps 4 through 7.

  9. 9

    Put on your goggles and knock down the nest, once there is no activity. Dispose of it in your dustbin.

    Underground Nests

  1. 1

    Wait until dark or before dawn before trying any of these methods.

  2. 2

    Put on several layers of old clothes, gloves, a hat and eye protection.

  3. 3

    Pour a solution of soap and water into the entrance. The soap will make their wings useless and they will be unable to fly.

  4. 4

    Apply an insecticide into the ground if the soap and water solution does not work. Pick one that is safe for lawns or soil. Dusts are very effective on treating wasps. Carbaryl (Sevin) and chlorpyrifos (Dursban) are two known for killing wasps and usually more effective than liquids. Apply liberally around the entrance of the nest.

  5. 5

    Cover the nest entrance with soil once the wasps have been exterminated.

Tips and warnings

  • While smoke is known to choke wasps, trying to use it to kill off wasps is very tricky.
  • Gasoline and lighter fluid will also kill wasps, but they are dangerous to use for this purpose.
