Many kinds of wasps, including yellow jackets and hornets, exist in the United States. Different species vary significantly in appearance, but the worst troublemakers for homeowners look very similar.

Frequently mistaken for honeybees, these stinging wasps have bright yellow-and-black bodies that measure from 3/8 to 5/8 inch long. Unlike fuzzy honeybee bodies, wasp bodies are glossy and nearly hairless. Depending on the species, their body markings include spots, triangles and irregular bands of yellow or black.


Stinging wasps are social insects that live together in large colonies. Their papery nests appear in trees, along roof lines, tucked into door or window corners — wherever they want to build. They often seek out spots close to where humans entertain outdoors, and then sweep in to steal food and drink.

Aggressive behavior — and stings to people and pets — are common with these flying pests. Unlike honeybees, which can only sting once, yellow jackets and other wasps can sting again and again. Reactions to their stings can be severe.


Treat wasps during their least active times to limit your likelihood of stings. Wasps move more slowly in early morning and late evening hours, so time treatments accordingly. Amdro® brand products can help you kill wasps and protect your family from their stings:
