Need help controlling Hornets?
In Ohio, several species of hornets can be found, with the most common being the European hornet and the bald-faced hornet.
Physical Description: Hornets are larger than yellow jackets and paper wasps. They have a black and yellow striped abdomen, with a mostly brown thorax and head. European hornets are around 1 inch long, while bald-faced hornets are slightly smaller.
Hornet Colony Structure: Hornets are social insects that live in colonies. The colony is started by a single queen in the spring. She builds a small nest and lays eggs that develop into workers. The workers take over the nest-building, foraging, and caring for the young, while the queen focuses on laying eggs.
Wasp Nests: European hornets usually build their nests in hollow trees, while bald-faced hornets create paper-like nests that are usually suspended from tree branches, shrubs, or even the eaves of buildings.
Diet: Hornets are predators and feed on a variety of insects, including flies, bees, and caterpillars. They also consume nectar and sap.
Defense Mechanism of Hornets: Hornets are known for their aggressive defense of their nests. They can sting repeatedly and their venom is more potent than that of bees. However, they typically only sting in defense of the nest.
Life Cycle of Hornets: In the fall, new queens and male hornets are produced. These individuals mate, and the new queens find sheltered locations to overwinter. The rest of the colony dies off with the onset of winter.
Interaction of Hornets with Humans: Hornets can become a nuisance if their nests are located near human habitation. It is important to exercise caution around hornet nests and consider contacting a professional pest control service if you encounter a nest near your home.
