Unusually active European Hornets in Missouri this fall due to warm weather.

The European Hornet is unusually active in Missouri this fall due to unseasonably warm weather. While generally not a medical threat, those allergic to bee or wasp venom risk severe anaphylactic reactions. These hornets are attracted to wood and may build large nests in trees or homes. Residents are advised to exercise caution until cooler temperatures reduce the hornets' activity.
