There are several species of yellowjackets. These flying insects
typically have a yellow and black head/face and patterned abdomen.
Yellowjackets are social insects that live in nests or colonies
with up to 4,000 workers. They are most active in the late summer
and early autumn when a colony is at its peak. Yellowjackets feed
on sweets and proteins, and therefore commonly invade outdoor
Yellowjackets can be found anywhere humans are found. They build
paper carton nests out of chewed up cellulose, which are usually
found in the ground or in cavernous areas such as eaves and attics.
Yellowjacket stings pose significant health threats to humans, as
they are territorial and will sting if threatened. They are known
to sting repeatedly and can cause allergic reactions. Yellowjackets
and other stinging insects send over 500,000 people to the
emergency room each year.
