WSDA worked to update and add to the Northern Giant Horner Identification Poster. You will want to view, download and print it by clicking here.

Northern giant hornet


Northern giant hornets are the world's largest hornet.
  • Usually 1.5 - 2 inches in length
  • Large orange head with prominent eyes
  • Black and orange/yellow striped abdomen
  • Forms large colonies that usually nest in the ground but also nest in tree cavities 



 

Sizing up the northern giant hornet

Below is a to-scale size comparison of the Northern giant hornet and several other insects.

Please note that the European hornet is often confused with the northern giant hornet but is the one species below which is not found in Washington. If you believe you have seen a European hornet in Washington, it should be reported to the WSDA Pest Program's Hornet Team immediately with a photograph or by submitting the specimen.

Is it an northern giant hornet?

Some local insects have been confused with northern giant hornets. The insects below are NOT northern giant hornets. However, if you aren't sure, please report your sighting, especially if you have photographs. You can also see more side by side photos on our NGH look-alikes page, or search for the hashtag #ThatIsNotANorthernGiantHornet on social media. 

 

Yellow Jacket


Yellow jackets are less than an inch long. They have distinctly yellow faces with a black area near the top of the head. Photo credit: M. Asche

Bald faced hornet


Bald-faced hornets are about an inch long and are mostly black with white stripes and spots. 

Paper wasp


Paper wasps are more slender and smaller overall compared to the Asian giant hornet. They also do not have an orange/yellow head.

Elm sawfly


The elm sawfly can be nearly as large as the northern giant hornet. They have a black face and yellow stripes, but they lack a stinger. Photo credit: Neil Boyle

Asian giant hornet attacks

You may not see northern giant hornets themselves, but you may see the aftermath of a hornet attack. These hornets will leave piles of dead bees, most of them headless, outside their beehive, similar to that shown in the photos below. These photos are courtesy of Washington beekeeper Teddy McFall. (WSDA has not been able to confirm that these are definitely the result of an AGH attack but they are consistent with one.)

     

Get involved

You can help prevent northern giant hornets from establishing in Washington. We have two citizen science projects to help detect the hornets: trapping and our Adopt a Wasp program.

Anyone in Washington State can participate in our citizen science projects, but we are especially interested in people placing traps or observing wasp nests in the following counties: Whatcom, Skagit, Island, San Juan, Clallam, and Jefferson. 

Even if you don't participate in a formal citizen science project, just keeping your eyes open for and reporting suspected sightings is a big help! More than half of WSDA's confirmed sightings have been from public reports.
