Pest Description

European Hornets in Las Vegas or Nevada

The European hornet, also known as the brown or giant hornet, gets its common name from being introduced to the eastern United States from Europe in the mid 1800’s. These hornets are found in 30 states, from the eastern U.S. as far west as Louisiana and the Dakotas. European hornets are much larger than yellowjackets, and unlike most stinging insects, can be active at night. Adults, possible seeking prey, come to lights in the evening and can be a source of great concern for homeowners here in the Las Vegas area.

European Hornet Habitat

European hornets are social wasps that normally build their nests in hollow trees, but will also utilize wall voids and attics of houses. Their nests will rarely appear freely suspended like the football-shaped bald-faced hornet nests. European hornet nests are generally located 6 feet or more above ground, and will occasionally be constructed on the sides of homes. In some instances, a portion of the gray, papery nest extends outside the cavity or void. An average hornet nest will have 200 to 400 workers by late summer and they can become aggressive if they feel threatened. 

European Hornet Behavior & Threats

Although large and fierce looking, European hornets will not sting unless threatened and tend to leave people alone. However, this hornet is capable of stinging multiple times, and those that may be allergic to their venom should seek medical attention when stung. European hornets can cause issues for homeowners by nesting in barns, hollow trees in yards, wall voids or attics. When food becomes scarce in late summer, they look for sugary foods and may destroy fruit trees. These hornets are attracted to porch lights at night and will sometimes bang up against windows, causing many a distressed homeowner.
