More on ‘murder hornets’ from local entomologist.

I’ve known Norm Baker for the last decade. He always has thoughtful information to share. While this is a comment in another post, I wanted to break it out to share more fully.


I am trained as an entomologist and am aware of the murder hornet and have been for many years. If this hornet becomes established and, that is quite likely, it will be a problem because of anaphylactic shock from the sting. When a hornet or yellowjacket or paper wasp sting, it isn’t a single injection. It is more like five or six injections in a very short row to get the maximum benefit or pain. Anaphylactic shock will be a matter of public safety and it may be necessary to broaden the purview of public safety a bit. I say this because being trained as an entomologist, I have seen two people go into anaphylactic shock after years, many years of working with insects and suddenly becoming susceptible to the sting or other insect protein. In one case, a 50-year-old woman researcher in the lab next to mine at U of M, had a cockroach run up her arm and she developed tiny red marks where the animal ran. A couple of months later, a cockroach escaped a culture cage, she grabbed it and put it back in. 20 minutes later she went into anaphylactic shock and if the lab technician and a couple of students had not been present, she would have died. In another case, a 55-year-old man who had worked with honeybees is entire professional life was so used to being stung, he simply ignored them. Unfortunately, he and a student were in the field and he got that one sting too many and started gasping for breath. If his graduate student had not been there, he would have died. Data on anaphylactic shock from insect stings, shows that 90% of the time, it looks like the person suffered a heart attack.

I read over the paper on where the Asian giant hornet can be expected to live and it is most of the Pacific Northwest. I can also tell from the eradication efforts by the Department of Agriculture, that all of their efforts still do not tell us if it is possible to control this animal. The problem is the fall dispersal of those queen hornets. They go into a kind of hibernation and in the spring, set up housekeeping very quickly and build a nest very quickly. My experience as an entomologist says this will eventually be a low level problem here in Clallam County. But, it will also take some training for EMTs and I can just about guarantee some of you police people are going to get involved indirectly because of the anaphylactic shock.

A lot of press time is devoted to the devastating effects of these hornets on bee colonies. What I have not seen is the use of a screen “excluder” that prevents the hornets from entering a beehive simply because they are much larger in size. It will simply be a matter of time before the nations beekeepers learn how to handle this hornet around their hives. The real concern here is anaphylactic shock that is passed off as a heart attack when no help is present and someone is stung.

But, there is more to the murder hornet then people really realize in this country.

The Great Bee Count – KPLU

The great bee count
By KPLU News Staff

For a number of years, honey bee populations have been shrinking. It’s called colony collapse disorder. To help understand this bee die-off, citizen scientists are being asked to keep an eye on their gardens this summer as part of The Great Sunflower Project .

The California-based project is helping scientists map pollinators around the country, including in Washington state. Steve Sheppard, a bee researcher at Washington State University, says there are so many insects and so few entomologists that for many parts of the country there’s not even baseline information about what is there.
