European Paper Wasp

European Paper Wasp vs. Yellow Jacket

While they look remarkably similar, you can distinguish a European Paper Wasp by its antennae. European Paper Wasps have orange-tipped antennae, whereas Yellow Jackets have completely black antennae. Additionally, paper wasps tend to be slightly more slender and fly with their long legs hanging down, while yellow jackets tuck their legs against their bodies during flight.

What Does a Paper Wasp Nest Look Like?

European Paper Wasps build open, umbrella-shaped nests where you can clearly see the hexagonal cells from below. Unlike yellow jackets or bald-faced hornets that cover their nests in a gray paper envelope, a paper wasp nest is exposed. You will often find these attached to:

• Overhangs and eaves
• Window frames
• Inside open garages
• Under deck railings

Are European Paper Wasps Aggressive?

These wasps are generally considered semi-social and less aggressive than yellow jackets. They typically will not attack unless you are very close to their nest. However, because they often build nests in high-traffic areas like doorways and decks, accidental encounters are common in Wisconsin homes.

Do European Paper Wasps Sting?

Yes, they can sting repeatedly if they feel their colony is threatened. The sting is painful and causes localized swelling or redness. While they are not as quick to swarm as yellow jackets, they will defend their nest vigorously if you attempt to knock it down.

Why Are They a Problem in Wisconsin?

The European Paper Wasp is an invasive species that has become dominant in Southeastern Wisconsin. They wake up earlier in the spring than many native species, allowing them to claim the best nesting sites and outcompete native wasps for food.
