I use a shop vacuum cleaner.
Just set the hose end right next to the coming and going spot/
works OK to the length of my extension cord ;-)
But, that brings out a good story/
When we first moved into this place in VT., everything was overgrown and brambles. Years of neglect by the previous owners.
The third year we were in, our son was just four, and he liked to follow me around. I had bought one of those big wheel self propelled walk behind mowers and was trying to make headway against the brambles. With the mower going, me at the handles, and my young son tailing behind, we crested one of the pitches that defines the back property. Somehow, and I'm not sure just how, I sensed over the racket of the mower blade and engine, that my son was in distress. I turned to look back at him and saw the swirling black dots , his face all in alarm, and his arms waving. I knew in an instant it was ground hornets . Yellow Jackets! Evil in physical form.
Well, I just let go of the brush mower, and it didn't have any auto stop, so just kept going. I grabbed my son into my arms and ran as fast as I could for the house, thinking if all else failed, the garden hose was there in the lawn. It was about a 40 yard run, with yellow jackets all about and in hot pursuit. The numbers diminishing with every yard.
Now I had heard two things that those nasty buggers. One was "The first one wakes 'em up, the second one gets 'em angry, and the third one gets the treatment" Mower, Me, then my son. 1, 2, 3/
The second was they will clamp on to the scent, and that was certainly the case.
Though my son suffered a half dozen stings while sheltered by my arms and body, I received NONE. They were going right around me to get to him, as I was brushing them away as soon as they would attach.
We had a spell of ground nests for a couple of years. I used gasoline and fire at first, but then switched to the vacuum set up. The canister has a side diverter just at the hose connection, These devil spawn must hit that deflector at about 200 mph! Serves 'em right.
I hear they really go for fresh meat. I know they like ripe peaches and split plums. Makes for some "spicy" picking.
Red hot sky raisins!
