Well, I tried them and they work! I pulled weeds in the garden for 1 1/2 hour last night and when I finished, there were 7 deer flies stuck to the back of my hat - and no bites! I called this number (231) 832-2323 and they mail you the patches immediately with an invoice enclosed. Twelve for $12, but higher quantities are cheaper. If the moderators take out the phone number, send me a PM and I will share it with you.
