Wasps and yellow jackets are the most common stinging insect we exterminate. They are social insects that produce new nests of paper each year with the help of wood and saliva. A colony is started by a queen, which is a fertilized female. The queen carries out all of the duties and chores of building a new colony; additionally, she feeds and develops her young. Later in the season, as the colony size rapidly increases, wasps are raised to assist colony development. At the end of the season, the nest is abandoned and the wasps disperse to find protection during the winter.
