I use Repel permanone spray for clothing and gear. This is an insectiside you spray on the clothing and let dry. Do not spray on your skin! Use on hat,coat,gloves, face mask, pants, and boots.
Also do an web search for tick gators, which are a camo elastic that covvers the joint between your boots and pant cuffs. I have gone in the woods in May and when I've sat down I was covered by biting bugs. After 10 mins or so there is no bugs anywhere. This stuff will last a washing or two so you don't have to use it each time you go in the woods. The active ingredent is Permethin 0.5% I know ticks I live in CT.
