European Paper Wasp | From the Ground Up

European Paper Wasp | From the Ground Up


The eaves of buildings like high tunnels and
outbuildings are a great place for paper wasps to build their nest. And we now have a new pest in the U.S. It’s been in the U.S. for a couple of decades,
but it’s just identified in Wyoming. It’s the European Paper Wasp. The insect itself looks very much like our
paper wasps that we’re familiar with. It has a little bit more of a slender waist
on it. And the antennae on this insect are a brighter
orange color. They have good and bad characteristics in
that they will feed on and are predatory towards things like caterpillars that we don’t want
in our gardens. But they are somewhat more aggressive than
other wasps, and they may become a problem because of that. The European Paper Wasp is known for feeding
on fruit that’s still hanging on the vine. Most of our other paper wasps or Yellow Jackets
will feed on fruit that is overripe, or fruit that has fallen from the vine. And so, we may see more loses from the European
Paper Wasp in fruit production across the state. They are known to have a paper colony, or
nest, that is very similar to other paper wasps. And if you do find them and want to control
them, you’d use paper wasp, hornet, or Yellow Jacket spray that has an immediate knock-down. And use all of the safety procedures that
we’ve shared with you in other “From the Ground Up” segments. So, you’ll want to keep an eye out for the
European Paper Wasp in your small fruit or garden production. I’m Donna Hoffman with the University of
Wyoming Extension, and you’re watching “From the Ground Up.”
