Now we're talking! I used Brake Kleen back in Kalifornistan on the yellow-jackets that used to congregate whenever I used a drill or a dremel. Kinda put the dampers on my motorized case trimming. Up here in Idaho now, we have hornets. I find it works just as well on them. I think I would like an adjustable choke on the spray tube though. Junior42 had a load he used on those bees if I remember. I think his was out of a .44? A Crosman smoothbore multi-pump BB gun loaded up with a wad of paper towel and a small amount of brass shavings from the case trimmer and another wad on top is OK but can leave some wounded and P.O.ed! Don't ask me how I know. Works great on Non-dangerous "insect game" like moths though. Use Enough Gun!
