Quick answer
Yellowjackets feed on insects, nectar and human food, adjusting with season, age, and what is abundant in Woodlands, gardens, and urban areas. That label is a preferred pattern, not every item an individual might sample.

Yellowjacket diet overview
Yellowjackets (Vespula vulgaris) are best summarised as Omnivore (insects, nectar, human food). Anatomy and habitat (Woodlands, gardens, and urban areas) decide whether they hunt, graze, filter, scavenge, or mix strategies across the year.
How yellowjackets find food
Energy-rich foods are prioritised when available; lean seasons force broader diets or longer travel. Young animals may eat different items or receive food from parents.
Yellowjacket role in the food web
As consumers in their food web, yellowjackets move nutrients and influence prey or vegetation.
Feeding and human conflict
Never feed wild yellowjackets. Habituation raises injury risk and can lead to lethal management. Captive diets must match species needs, not generic pet food rules.
A society in a paper nest
Yellowjackets are social wasps that build nests from chewed wood pulp, creating papery combs often hidden underground, in wall cavities, or in bushes. A single queen starts the nest each spring, and the colony can grow to thousands of workers by late summer before dying off in autumn.
Sting and defense
Unlike a honey bee, a yellowjacket has a smooth stinger and can sting many times. They are highly defensive of their nest and will swarm to attack a perceived threat. Their stings are painful and, for people allergic to insect venom, can be dangerous.
