Paper wasp nests look like upside-down umbrellas. These nests are often open and can get quite large, with a single stalk consisting of paperlike material supporting them. You will usually find paper wasp nests hanging from eaves, trees, and bushes. They can also be found on porch ceilings, window and door frames, roof overhangs, attic rafters, and under decks.
While paper wasps are not as aggressive as other types of wasps, they will sting if they feel threatened. Therefore, if you have a paper wasp nest on your property, it is best to leave it alone and call a professional to remove it.
