Transition Yellowjacket (Vespula flavopilosa)

Habits:

Transition Yellowjackets will scavenge for meats and sugary foods, and may be pests around trash cans and outdoor activities.

Nests:

Transition Yellowjacket nests are subterranean, tan in color, and carton-shaped. The nests will have between 500 and 1000 workers at peak size. The Transition Yellowjacket commonly nests in yards, along roadsides and in manmade structures.

Nature toward humans:

Transition Yellowjackets are "picnic pests" and may be a hazard if agitated while they are scavenging. They are also a stinging hazard if the nest is disturbed. Since they are more likely to be found near human activity, Transition Yellowjackets present more of a stinging hazard.
