when is the best time to spray a wasp nest
Locate the wasp nest by examining all protected areas in the vicinity of wasp activity. Just removing the wasp nest will not resolve the problem, because surviving wasps will reconstruct a new one. The best strategy is to treat the wasp nest at night when all the workers and queen are present. Spraying into hornets nests should ALWAYS be done at night. They are far less aggressive and are all at home. This tactic maximizes the effect of the pesticide application by killing most if not all of the wasps.
