Ya wait till the middle of the night when all the hornets are home in their beds asleep ...
Then ya sneak-up with a gasoline soaked blanket to tuck them in with . Its a nice thing to do , especially if ya pour more gas on top of the blanket after their all covered up .
Ya don't have to light it up , just the fumes are enough to let them know Exactly how ya feel about them.
That video gave me "Night-mares too" . but it reminded me of a hollow tree near my house that was full of them giant hornets. --
We went "dangerous game" hunting with our pellets guns till we got tired of shooting , yea the more we shot the more they swarmed.
Then after a night of having the exit hole clogged with a "Gas-rag" , there was a 5 gallon bucket full of them dropped to the bottom of the hole. Of-course with their size it don't take but a few hundred of them to make 5 gallons !
These have been in Tennessee for 30 years that I know of.
yea they look exactly like this , and 1.5" to 2" long.
