Prepare Soap Solution
The most effective tip to get rid of wasps is spraying soap water. In a mop bucket, mix 4 tablespoons of regular dish soap in 1½ quarts of water. You can splash this solution in the nest, directly from the mop bucket. Wearing protective clothing and gears, keep safe distance from the nest. Slosh the soapy water into it all at once, and quickly step back.
