I tried the Defend patch last weekend. I had mosquitoes crawling all over me, but didn't get bit. Although they weren't biting they were everywhere. With having so many buzzing around me I couldn't fight the urge to try to wave them away, which wasn't doing much for my ability to sit still so I turned on my ThermaCell.JRS wrote:Off topic, but in the latest Ont. Out of Doors, there is an ad for a product called Insect Defend Patch. I have seen it in the local Walmart. It is a stick on patch that is supposed to be good for 36 hours of insect protection using Thiamine (B1) and your body's chemistry. Supposed to be waterproof too, and good for ages 1 and up.

My observations on the patch:
I would say the patch worked as advertised. I'm a mosquito magnet. I don't just get bites, I get big WELTS. (Clariton keeps the welts and itching down a bit).
It takes a while to kick in so it's best to put it on a few hours before you need it. It seemed to work for the full 36 hrs that it said it would.
I found that my skin developed a smell that I can only describe as "vitaminy". First just at the patch location, but but then 2nd day it was everywhere. I smelled like a vitamin B supplement - and there is a reason for that since the patch works by infusing vitamin B1 into your system.
I would use it again, but I wouldn't leave my ThermaCell at home if I was planning on trying to sit still.
I imagine it would be handy for sitting out around the campfire in the evenings - would keep you from getting the surprise bites from the stealth mosquitoes.
