How to identify and get rid of European hornets

Sometimes bigger isn’t always better, especially when it comes to hornets. Even though the European hornet may originate from across the pond, it has made its way into the Midwest of the US and called it home.

European hornets are a bigger and more robust hornet than our native wasps, and can often be a menace. While they play a crucial role in the ecosystem by controlling pest populations, their presence can be unsettling, especially when they decide to nest near human dwellings.

Luckily, these foreign hornets tend to keep to themselves and aren’t too aggressive. They tend to build their nests out of a paper-like substance in the hollows of trees. If they don’t have a nice tall tree around, they may turn to a home or building to build their nest.

The nests continue to get bigger throughout the summer and typically only house 200-400 workers, but some large nests can get up to 1000 workers. These nests are only active for one year and during the winter they die out. The queens that emerge from the nest late in the season will overwinter and make a new nest the next year.

While European hornets are often seen as a threat and can sting if provoked, they can be beneficial to gardeners. They prey on grasshoppers, flies, caterpillars and even yellowjackets. Additionally, they may feed on tree sap and fruit.

European hornets are noticeably larger than typical wasps and can be identified by their unique color pattern of a yellow and black abdomen with a distinct reddish-brown thorax. They are known for their loud buzzing and are often seen flying later in the evening than other wasps.

Their eyes are notched by their antennae, giving them a “C” shape. They also have reddish-orange wings.

If you start noticing these hornets around your home more frequently, especially at dusk, it's likely there's a nest nearby.

Common characteristics of European hornets:

• Yellow and black abdomen
• Red thorax
• Eyes shaped like a C
• Reddish wings

How big are European hornets?

European hornets are quite large, typically measuring between 1 and 1.5 inches in length.

European hornets were first introduced into the US in the 1840s and cover much of the East Coast and Midwest.

European hornets can sometimes make their nests in or around your home. If you catch it early enough, you can remove the nest when the hornets are less active. However, if you discover a large nest that is inside the walls of your home, it may be best to call a professional to handle it.

To prevent European hornets from turning your home into their home, consider these tips:

Prevent Entry: Seal all entry points to homes, such as gaps in roof eaves or holes in walls.

Remove Attractions: Keep garbage cans sealed and fruit trees picked to reduce food attractions.

Water Sources: Eliminate standing water to discourage hornet presence.
