Tips for Keeping Hornets Under Control

Yellow Jacket

Hornets (yellow jackets) belong to the family Vespidae. All yellow jackets sting and their stinging behavior is considered a defensive reaction when the colony is threatened. They can sting more than once because their stinger stays with the insect. Yellow jackets are more aggressive during August and September and more likely to sting. Although yellow jackets are a beneficial insect because they feed on other insects, they often become a pest problem when nests are located near homes, schools, picnic areas or playgrounds.  (Prairie yellow jacket photo by W.
