I use Sawyers brand repellent with permethrine. The carrier is the repellent, and the permethrine is a killer. This is for clothing only. It WILL keep the ticks off ya'.
For the body I buy the highest DEET percentage bug spray (Off, for example) I can find. When it's really bad out, I soak a bandana with it and tie it around my neck.
Keep swattin',
