Ticks. Mosquitoes and those damned Buffalo gnats. It might take some experimentation but it behooves everyone to figure out a concoction that will repel all three. Most of us use a combination of deet or deet substituted repellant for ticks and mosquitoes and a good spray or two of lemon eucalyptus stuff to keep the gnats away…but whatever works for you, use it. Prepare, Train, Succeed.
