However, unlike bald-faced hornets, which build the large, exposed paper nests in trees, and yellowjackets, which typically build paper nests in the ground, the nests of European hornets are found in protected aerial areas, such as a hollow in a large, standing tree and sometimes in the wall voids of house…

Medical Importance

  • Despite their large size, the sting from a European hornet is only about as painful as a honey bee sting. Unlike honey bees, European hornets have smooth stingers and can sting multiple times. Unless a person is allergic to bee and wasp stings or received multiple stings, European hornet stings should resolve on their own in one to a few hours without complications. If adverse reacti…

Control

  • Because European hornets construct annual nests, the simplest method of control is to wait until the first hard frost or two kills off nearby nest(s).
