Insect Shield is effective against mosquitoes, ticks, ants, flies, chiggers, and midges. Since gnats aren't blood feeders, permethrin isn't the right active ingredient for them.
“We had a mild winter here in North Alabama, therefore when turkey season rolled around this spring, I knew the ticks would be in full force. I purchased Insect Shield camo and hunted with a friend. Each morning he would soak himself down with bug spray, it didn't work with the ticks. He picked ticks off himself and fanned mosquitoes wen he could have been hunting. I never saw a single tick and was never bothered by mosquitoes. Insect Shield works...!”
