Deep Woods off is some good stuff.
Also, long sleeves are a must, and gloves.
Also, be mindful of the soaps and shampoos you use whilst hunting. If hunting by yourself, or with like minded individuals, forego showering with scented soap and shampoos before a hunt(plain Dial soap is great for rplling ticks) and don't wear any sort of deoderant before going into a blind, it will make you less attractive to bugs.
