Wasps are buzzing, stinging pests that can make quite a nuisance of themselves in yards and gardens. For people who have pets and children, wasps in the yard can be dangerous. Some wasps are nonaggressive, and can actually be beneficial because they eat other insects. However, if you don't want wasps in your yard, there are some easy ways to get rid of them. Winter is actually the best time to do so, as cold temperatures make it difficult for wasps to fly and move.
Identify the wasp nest. During cold winter, wasps will be inactive and very sluggish. This is the best time to kill them. Look for nests high up on walls, in corners and in the eaves of houses. Mud daubers build nests out of mud, while other wasps build nests out of chewed-up plant and wood matter.
Spray the nest with PT Wasp and Hornet Killer until the nest is soaked. Treating the nest at night will make the wasps even less likely to react.
Allow the pesticide an hour to kill any inhabitants in the nest. Then knock it down with a broom. Destroy the nest and throw it away.
