- 1). Use insecticide, in the form of hornet and wasp spray on either type of nest. Wear protective clothing and treat the nest at night. For an elevated nest, use a spray that projects about 15 to 20 feet. This will reach most nests and give you a safe distance to work with. If the nest is underground, use a small amount of the spray to avoid contaminating the ground.
- 2). Use boiling water as a safer method to get rid of an in-ground nest. Boil a pot of water and pour it into the hole leading to the underground part of the nest. Do this late at night to catch them while they sleep. This method may be less effective than an insecticide but it will do no harm to the environment.
- 3). Repeat either method up to three times or until you no longer see wasps or hornets in the area.
