We have been 'attacked' several times, always this time of year. When you find the 'swarm' after the attack, with binoculars usually, my husband will take a small limb and lay it so that it points towards their entrance. That helps us find it after it starts getting pretty dark. Always wait till just before dark. He has a funnel that he fuels his lawnmower with. He puts a cup or two of gasoline in the funnel while holding his finger over the bottom hole. He puts the funnel over the whole and moves his finger, letting it drain down the hole, then pours a small trail of gas from the whole 3 or 4 feet away. Then we just light a piece of paper towel and toss towards the 'lead line' of gas. It will burn slowly for 15-20 minutes. You never see them again! Just be careful, we are around 40 days without rain, so everything is really really dry. Only want to burn the bees!
