Last year I enough permitherin left to do my shirt and just the top of my pants, so I sprayed my legs with OFF a couple of times while was out hunting. I noticed a tick making his way up my leg. His progress was varied, but when he got to where the permanone was he got real slow and then just sat there. Eventually he was not holding with all of his legs and then he was dangling by his pinchers. Finally the poor little feller could not hold on any more and he fell to the ground and he lay there on his back and he died. Funeral and burial services were held on the spot. He or she was survived by the dozen or so siblings that were snagged up in my wool socks, who also died, one at a time because of run away cigar fire. Please don't tell the PETT folks about this, people for the ethical treatment of ticks.
