How to identify the Eastern Yellowjacket

A shiny, smooth wasp with bright yellow and black bands; it is not fuzzy like a bee.
A narrow "waist" between the thorax and abdomen.
Folds its wings lengthwise when resting and flies quickly from side to side.
Size: 10–16 mm.

Where it lives

Common in eastern North America. Similar yellowjackets live in Europe and elsewhere. Nests are usually underground in old burrows, or in wall gaps and sheds. In late summer they are drawn to sweet drinks, fruit and rubbish bins.

Is it dangerous?

Yellowjackets can sting many times and become aggressive when their nest is disturbed. A sting causes sharp pain and swelling. For people with a venom allergy, or after many stings, it can be a medical emergency.
