Paper wasps are about 3’4” long and are a commonly burnt orange-brown color. They can also have black and yellow stripes making them easy to mistake for yellow jackets. Their nests are often referred to as umbrella-shaped since they hang upside-down attached to surfaces by a thin pedestal. These nests are made up of a grey paper that is about 1-2” thick with open cells facing downward with a honeycomb pattern. Paper wasps scrape wood shavings off of decks, picnic tables, wooden furniture, and other wood around your property, turning it into a paste when mixed with their saliva. This is the building material that they use to create their unique nests. Although most paper wasp nests are grey, their nest colors can vary based on the available materials in the area.
