Although they are often confused with bees, wasps are a different species of winged insect. Like bees, wasps do sting when provoked and their stings are painful and can be dangerous to someone with an allergy. Wasps set up nests in the ground, in trees or even in the siding of a house. If wasps are living in your siding, using an insecticide wasp dust is a safe way to remove your wasp problem.
Wear protective gear, such as long sleeves and long trousers. Also wear work gloves and protective eyewear to protect you from stings. Congregating wasps can become aggressive. Complete your inspection and treatment of wasps in the evening hours when they are less aggressive. More wasps are also in the nest at this time, so you will kill more of them.
Inspect the outside of your home for the entrance to the nest. Look for a high concentration of wasps. If the nest is not exposed, drill an 1/8 inch hole through the siding where you see the wasps congregating. Add several more 1/8 inch holes every 3 to 4 inches for one foot on either side of the first hole.
Insert the nozzle of the commercial wasp dust into the holes. Squeeze the dust to inject it into the holes. Follow the specific instructions on the can for best results. For an exposed nest, spray the dust in a sweeping motion over the nest.
Watch the nest area the following day to look for wasp activity. If you do not see activity, you have successfully got rid of your wasp problem. If you see wasps, wait three days and repeat step 2.
Seal the entrance to nest with plumber's caulk once the wasps are all dead. This will prevent wasps from using the old nest in the future.
When choosing an insecticidal wasp dust, choose one that contains bendiocarb, boric acid or chlorpyrifos.
Never seal the entrance to the wasp nest if there are living wasps. Sealed nests cause wasps to seek escape in your home.
