Giant Hornets

Vespa crabro, known as the European hornet, may be called a giant hornet in U.S. Giant hornets may also be a term used for the bald-faced hornet. However, unlike the bald-faced hornet, the European hornet is thought to be a true hornet species.The giant hornet (Vespa crabro) measures approximately 20 to 35 mm in length, although males and workers are smaller than queens. Like other members of its species, the giant hornet’s abdomen is segmented: males have seven segments and females have six. Giant hornets’ eyes are deeply indented. The head, thorax, legs, wings and first abdominal segment are reddish brown. The other abdominal segments are dark yellow in color. While sparse hair is visible on its body, the giant hornet is less hairy than bees. Although their size can be imposing, the giant hornet is less defensive than wasps like the yellow jacket. They tend to avoid human contact, fleeing rather than attacking. However, giant hornets will defend their nests aggressively if threatened. If a nest is located inside or in close proximity to your home, a pest control professional should be contacted.
