I unfortunately discovered that I have a huge Yellow Jacket infestation in the center of a large bush. The bush is about 24" around at the base and the base is packed about 8" deep with years of dead leaves and debris. Most of the bee activity seems to be concentrated near the center of the debris. I figure the hole is located somewhere UNDER the dense leaves and debris which makes precise location of the hole nearly impossible.
I tried dousing the area with bee-killing insecticide then later flooding the whole area at night for about 20 mins and both was totally ineffective.
This evening I took a long pole and agitated the leaves in the center of the bush and that resulted in a huge swarm of bees all around the base of the bush.
I've taken care of Yellow Jackets in the past but in those cases the hole in the ground was in a clear area so it was easy to fill with kerosene, light, and enjoy the show.
I'm thinking I may have no choice but to soak the base of the bush with kerosene and do an initial burn to see if it either kills them or reveals the hole. The bush is out in the middle of the yard away from everything and I'm not concerned about saving the bush as it is an eyesore.
Does anyone have any alternative words of wisdom before I embark on my fire bombing mission?
