Giant Asian Hornets

Perhaps you’ve heard about a Giant Asian Hornet having been spotted in Arlington Heights, Illinois recently. So what is the buzz on this potentially deadly behemoth? Giant Asian Hornets (Vespa mandarinia) originate in Asia and are quickly spreading across the globe. There are reports of infestations in Alabama, California, Georgia, Illinois, Indiana, Iowa, Kentucky, Louisiana, New Hampshire, New Jersey, New York, North Carolina, Ohio, Oklahoma, Pennsylvania, Tennessee, Texas, Vermont, Virginia, and West Virginia. Climate change and global shipping are believed to be the culprit behind the spread.
So what makes this new invader so unique? Giant Asian Hornets (also known as Japanese Giant Hornets) are the largest hornets in the world. The average specimen grows to 2.2 inches in length and is the width of a human thumb. They can travel 60 miles per day at speeds of nearly 25 miles per hour. It is a ruthless predator that kills other hornet species, yellow jackets, bees, large insects and mantises. The Asian Giant Hornet often scouts out honey bee hives and marks the hive with a pheromone. They then return with about 30 more Asian Giant Hornets to attack the hive. About 30 hornets are known to kill about 30,000 bees in their bee hive in about three hours. They kill the bees by splitting them in half with their mandibles. The larvae of the bees are then used as feed for their own nests.
As if that weren’t terrifying enough, the hornets are known to be very aggressive to humans as well. Citing Chinese government sources, CNN reports that at least 42 people have died and 1,675 have been injured as a result of giant Asian hornets in Shaanxi province since July. Vespa mandarinia carries venom that destroys red blood cells, which can result in kidney failure and death, and noted that allergies to the venom can trigger cardiac arrest or cause airways to close. The pain of the Asian Giant Hornet is described as a hot nail piercing the skin. While the pain of a yellow jacket sting last about four minutes, the pain of an Asian Giant Hornet last about four hours with instant swelling.
Because of our changing climate, increasingly long and hot summers have led to an overall increase in the insect population, including the other hornets, wasps, and mantis that make up the Giant Asian Hornet’s prey. As such, it can be expected that this flying invader will become increasingly common as time goes by. Take extra caution looking for hornet nests and wasp nests on your property or whenever you are spending time outside. Wasps and hornets build nests in trees, in bushes, under eaves of homes, and in the ground — especially at the base of shrubs.
