Paper wasps eat nectar and other insects including caterpillars and flies. In the autumn, future queens will seek places to spend the winter and may find their way indoors.
Then, in the springtime, they will emerge to build their umbrella-shaped nests that look as though they are made of paper. Paper wasps build their comb nests to hang from objects like twigs and branches of trees and shrubs, porch ceilings, the tops of window and door frames, soffits, eaves, attic rafters, deck floor joists, railings and more. Each nest has open, uncovered cells where the eggs are laid. Other females will help build future nests, and only the one queen will lay eggs for the colony. Once that queen dies, a new egg-laying female will take her place.
