Yellow jackets have sometimes been mistakenly called bees, but they are in the wasp family.The workers are 3/8-5/8 in length and have a yellow and black face and patterned abdomen.
Yellow jackets are social pests living in colonies containing workers, queens and males. They nest in areas such as eaves, in the ground or attics. They feed on sweets and proteins and commonly invade outdoor activities. Yellow jackets pose health threats to humans and can cause allergic reactions.
Do not leave sweet drinks or meats in accessible areas. Clean up and remove trash and food after outdoor activities.
