Bold Face Hornet

Yellow Jacket


Hornets, wasps, yellow jackets and bees are all eusocial insects, meaning they work together to create a living situation favorable to the entire brood.

Hornets build a communal nest by chewing wood to a papery pulp and construct cells in horizontal layers, these nests can be in trees, shrubs, underground or attached to structures. Hornets  and wasps can sting repeatedly and inject acetylcholine. Allergic reactions can be severe and may require epinephrine injections to counteract the venom. Unlike the honey bee, hornets, wasps and yellow jackets do not lose their stinger and die after stinging their prey.

Hornets, wasps and eusocial insects can release an attack pheromone in case of a threat to the nest mobilizing the entire nest to sting the attacker. Additionally certain food flavorings and fragrances containing certain alcohols and esters can trigger an attack by the entire nest.
