Habits

European hornets are social insects and live in colonies that may contain between 200-400 members at their peak. They usually appear in late summer. They prey on a variety of large insects such as grasshoppers, flies, yellow jackets and honeybees. They also eat tree sap, fruit, and honeydew. European hornets are attracted to light and are known to repeatedly bang on lighted windows at night.

Habitat

European hornets nest in hollow trees, barns, out buildings, hollow walls of houses, attics, and abandoned beehives. Unprotected nests are usually covered in a brown envelope made of cellulose from decayed wood.

Threats

European hornets can do a great deal of damage to trees and shrubs because they strip the bark to get to the sap. They also use the bark fiber to build their nests. They have smooth stingers, so they can sting over and over again. Their stings also carry venom that makes the stings hurt, itch, or swell for about 24 hours. A European hornet sting has the same risk of allergic reactions as with other insect stings.

Prevention

Change exterior lights to yellow bulbs to reduce this pests’ attraction to your home or property. Promptly remove any fallen fruit from trees, as it attracts these hornets. If you suspect you have a European hornet infestation or find a nest on your home or property, contact a licensed pest management professional. Do not attempt to remove a nest on your own.
