Michigan’s Buzzing New Neighbors: How Climate Change Is Bringing European Hornets Closer to Your Backyard

As Michigan residents enjoy increasingly warmer temperatures and milder winters, they’re not the only ones adapting to the changing climate. European hornets are one of the largest species of social wasps in Michigan. They are currently found in the southernmost areas of the Lower Peninsula. However, climate shifts are creating conditions that could allow these impressive but intimidating insects to expand their territory northward, bringing them closer to neighborhoods across the state.

Understanding the European Hornet Expansion

The European hornet (Vespa crabro) is the largest eusocial wasp native to Europe. It is also the only true hornet (genus Vespa) found in North America, having been introduced to the United States and Canada from Europe as early as 1840. The large-bodied insect is now common and widespread throughout the eastern U.S., and it seems to be moving further south and west.

What makes these hornets particularly noteworthy is their size and distinctive appearance. At 1.25 – 1.5 inches (3 – 3.8 centimeters), the queens are quite noticeable. Workers are slightly smaller at a length of 0.6 –0.8 an inch (1.5 – 2 centimeters). The margin of their eye and thorax have an orange-brown coloration, as does the very front section of their abdomen.

Climate Change: The Driving Force Behind Range Expansion

The relationship between climate change and hornet expansion is becoming increasingly clear to researchers. Climate change could provide the hornet a more suitable habitat in the United States. “This hornet can exist in temperate regions anyway, simply broadening its range,” said James Carpenter, a curator of wasps at the American Museum of Natural History in New York City. “It would be allowed by a warming climate to do that.”

Similar patterns are already being observed with other species in Michigan. Milder winters and longer warm seasons have allowed ticks to expand their range, bringing Lyme disease to more areas within our state. The warmer temperatures and increased humidity create ideal conditions for ticks to flourish. This same principle applies to European hornets, which benefit from extended warm seasons and reduced winter mortality.

Climate change may be expanding the habitat for the Asian giant hornet within certain regions rather than worldwide. “There’s every reason to believe that that wasp will ultimately have or that hornet will ultimately have a wider habitat range than it will under current conditions.”

What This Means for Michigan Homeowners

While European hornets may sound alarming, it’s important to understand their behavior and actual threat level. European hornets can and will sting if they feel they are under threat. However, they are not considered dangerous when passing by despite their size and loud buzzing, but they are defensive and will sting if they, or their colony, are threatened.

European hornet nests are constructed in trees or rotting wood but sometimes can be made in walls or attics. One can find between 200-400 adults in one nest and workers are active both day and night. They seem to like light at night and may bounce off windows, like June Bugs.

For homeowners, the key considerations include nest proximity and potential encounters. If you spot a wasp nest, the decision to control will depend on the proximity of the nest to areas where you or others spend time outdoors. Nests near door entrances or patios are more likely to result in unwanted encounters with wasps compared to nests in a far corner of the garden.
