This time of the year, nests of stinging insects are angry. They are ready to attack and defend their nest. Buying a can of spray to try to treat these nests is both dangerous and usually unsuccessful. See the two examples of nests found within homes and you can imagine how many stinging insects were inside. Once one member of the colony stings you, a pheromone is released calling others to defend the nest. Please leave the treatment of these insects to the professionals this time of the year.
