falcon..just as an aside i was surprised at how well permethrin works.i sprayed the inside of my one man tent and the underside of the rain fly.there is no way to get into my tent without a few bugs getting in.in the past i have spent over 15 minutes tracking them down and trying to kill them,a tough job as they "see" you coming.this year by the time i got in and settled down the nasty little biters were already "stunned and confused".i was able to kill several at a time between my hands.no live spiders turned up in the AM when i was clearing out the tent to pack and at night when i had a light on to read the moths and whatever that get between the tent and fly and flap around did not last long.
