Should have waited till dark when all the hornets are in and sleeping. Then hit it with lots of killer spray. We found years ago that straight gasoline will kill them dead, dead, DEAD! instantly! Just don’t smoke when you spray it or you will still kill them and lose the shed.
Yep.
Never attempt a maneuver against bees in broad daylight.
This was an internet look at me!!!
Yep, douse with gasoline.
When I had them in the ground I didn’t even light it. After dark plug the hole with a rag then pour half a cup or so of gasoline on the rag and go back in the house. No fuss, no muss. Next morning, all dead.
