Hornets are part of the Vespidae family and are considered eusocial wasps. There are several different species.
In North America, they are referred to as hornets, but they are actually yellowjackets. Some large wasps such as the bald-faced hornet are sometimes referred to as hornets.
The species got its name because they make aerial nests to live in instead of subterranean nests.
Hornets eat other insects
When threatened Hornets will guard their nests aggressively. They will sting. The sting is more painful and can be more dangerous than those of bees. The stings venom contains acetylcholine and can be harmful to those who are allergic. They do not die after they sting, therefore they can sting over and over again. It is vital for an allergic person to get immediate help.
Prevention and removal by a professional pest control company is vital. The nest must be treated first by drenching and dusting. It is also recommended to treat in the evening when hornets are less active. If removing when hornets are active there are additional methods that need to be taken. If not done correctly adult hornets may be killed, however hatching hornets may be left behind.
Hornets can be beneficial since they prey on insects but can be harmful to people and pets. In the warm weather, a nest can be home to several thousand. When the cold weather approaches, they all abandon the nest leaving the queen behind. She will find a safe spot for the winter only to return in the spring to build a new nest and produce new offspring.
They are generally brown in color with red or yellow markings. Some can be dark red.
