The job I'm working has them flying around and I noticed a couple small TOH's on the edge of the driveway. Upon closer inspection today the base of them were covered with SLF's worse than this photo. Showed the lady and she OKed the use of fire to eradicate them. I had some fun with the blowtorch and guessing I killed over 100. I still have that TOH to harvest from last week. Wonder how bad they are there?
