European Hornets

Identification

• Large, ¾-1 3/8″

• Brown and yellow coloration

• Make unprotected brown nests

Environment

• Nests are built in hollow trees, barns, out buildings, hollow walls, attics, and abandoned bee hives

• Prefer a more forested environment

Threats

• Nests may be in human occupied areas

• They are attracted to lights, and may be attracted to structures with lights

• May kill plants trying to feed on sap/nectar

• Relatively non-aggressive near the nest, but there is still some potential for a stinging hazard

• Stings may be life threatening in sensitive individuals

Treatment

• Make the area less attractive for nesting and feeding purposes

• The nest will be located and treated with an appropriate product if necessary

• European hornets are beneficial organisms and are therefore only controlled when they pose an immediate threat
