The Asian giant hornet (Vespa mandarinia), also called the Asian Killer Hornet or Japanese giant hornet is the world’s largest hornet. It is native to temperate and tropical Southeast Asia, and parts of the Russian Far East. It is also found in the Pacific Northwest of North America as of late 2019, with additional sightings in 2020 and 2021, drawing concern that it could become an invasive species. In this article, we will discuss the topic of what do hornets eat.
The Asian giant hornet is extremely predatory. It hunts medium- to large-sized insects, such as bees, other hornet species, and mantises. Asian giant hornets or killer hornets attack honey bee hives to get the adults, pupae, and larvae as food for their own larvae. They are sometimes known to cannibalize each other’s colonies. A single hornet can kill as many as 40 bees per minute due to its large mandibles or crushing jaws. Only a few hornets (less than 50) can exterminate a colony of tens of thousands of bees in a few hours.
Should You Be Afraid Of Japanese Killer Hornets?
Asian giant hornets, also known as Japanese killer hornets, “giant sparrow wasps,” or “murder hornets,” are very frightening. They are the largest hornet species in the world. Giant hornet workers can grow to be anywhere between 1 ½ inches to 2 inches. Giant hornet queens can exceed the 2-inch in length. Their wingspans commonly measure in at 3 inches. Wow!
The good news is that in most cases, the killer hornets will not show any aggression towards you if you don’t show any aggression towards them. Asian giant hornets were responsible for less than 13 deaths in Japan between 2017 and 2018. However, it’s best to always navigate with caution.
Still worried about the possibility of a hornet sting? Here are some things you can do to lower your odds of a killer hornet run-in:
- Asian giant hornets are attracted to dark colors. If you are roaming around a mountainous terrain or a forest full of foliage, stick to whites and pastels.
- Hornets are drawn to sweet smells. Leave the sodas, sugary snacks, and sweet smelling perfumes at home.
- Avoid areas where tree sap is preset. Japanese killer hornets will always find their way to a sap-tapped tree.
