Try to find some permanone. I got mine in the camping secion at wal-mart. Spray it on your clothing only. It smells when you put in on, but after waiting a couple of hours...it's odorless.
Thermacell works good too, but I like the double protection. They say...although I have not tested it yet, that the permanone will last through a couple of washes.
It's getting a little cooler for us here in MD so hopefully it won't be an issue for long.
