Last spring I did a test with some Rail Riders pants with InsectShield, which is supposed to repel/kill ticks.
While doing one my 3-4 weekly short hikes in a local park I found a deer tick on my dog's front leg, which I removed and put on the thigh area of the pants. I sat down on a rock to see how the tick would react. He crawled around for a while as I kept him corralled in the same little area. I kept expecting him to curl up, or to show some sort of distress, but it never happened. After about 15 minutes I flicked him off, got up and continued on... with substantially less faith that this stuff does anything at all.
The instructions say the InsectShield treatment is good for 70 washings, and these had been washed only once.
