I HATE BEES! ALL BEES! You did a great job. For underground yellow jackets I have in the past used 2 gallons of 87 octane + 2 bottles of Sterno. I used to light it from 10 feet away with CRC brake cleaner with the little red hose attached and a Bic lighter. If the hole started to burn out I would fill balloons with gas or Sterno and roll them into the hole. FIRE FIRE I LOVE FIRE !
Nobody around to take pics... The job is done though... A whole can of cheapo NAPA brand brake cleaner, then sealed the entire opening off with Great stuff foam. I could get pics of the foam when the sun comes back out...
A new method for yellow jacket extermination... call in an air strike. [ame=http://www.youtube.com/watch?v=JHFO30_W0Ek]Yellow jacket extermination - extreme - YouTube[/ame] Damn it Jim... I'm a doctor, not an exterminator!
