When dealing with social wasps, protective equipment including a bee hat, long sleeve shirt, coveralls, eye wear, and gloves should be worn. Just removing the nest will not be enough. Surviving wasps/hornets will just construct a new one. This is why, knowing how to kill wasps is important.

The best strategy is to treat the nest at night when all the workers and queen are present. Dust, aerosols, and liquid formulations are effective against wasps/hornets.
