Hornets

[buffalorifle]

New here, been following the forums for some time, homeowner been cutting firewood off and on since 1970's.
I recently had a 80-ish foot red oak blow down along the back of my yard and want to cut it up but it is hollow and full of the huge european hornets from break at the stump to roughly half way up. The worst part is I am severely allergic to them. I see no way to treat / kill the nests without splitting the tree which I cannot do. The only option I see is hiring exterminator and not so sure they can do it, or wait till winter freeze to kill them.
Any other suggestions would be welcomed. Every day I look at that tree laying there and start salivating at the thought of attacking it with my saw and splitter.

I use tempo dust at night for YJ , should work fine for hornets.
As long as you can get some by any entrance it should work.
If you think you will get stung even at night, then call someone.

We have baldface hornets here who leave guards at night. Don't think the European ones do, maybe you can google that just to figure out your strategy.

M80 will blow them to smithereens
Or Tempo dust

Never heard of Tempo dust... is it available at hardware stores? Mostly used spray but with nests in hollow tree not accessible.
European hornets are active at night and attracted to light so was thinking bug zapper but not sure of getting them all.

I would wait until the cold renders the hornets harmless.

And save the money.

I wonder is a 100% kill rate is achieved by the exterminator?

If not...I'd hate to have a few angry ones buzzing around.

This is a effective bee killer. I use a similar product with the same active ingredient (dinotefuran)as this.

Spoonful of Sevin dust in the entrance will end them. Make sure they have to walk through the dust to get into the nest.

If you're allergic, I agree with the others saying that risking even one sting isn't worth it.

Don't go near them, get a person who isn't allergic to spray them at night!

Most if not all crawly flying insects dislike diatomaceous earth.

Anything with an exoskeleton will be torn apart by DE. Have to get it all over the critters, though. I've used a cheap Harbor Freight sand blaster to dispense a cloud of DE into wall cavities, worked great. It's near pure silica and can cause silicosis with enough exposure, a respirator is probably a good idea.

I use DE quite a bit. In fact I just killed a ground yellow jacket nest along our sidewalk to our main entrance.

For the yellow jackets I used about ten ounces of DE(volume measurement) and would go out each night and push the DE over the newly opened hole the yellow jackets had formed.

After about three days I would poke the whole nest and stir in the hole in the ground.

After five or six days I see no daytime activity.

I would imagine hornets living in a large trunk cavity would be more difficult to control so I would be quite leery, especially if I were allergic.
