Currently there are no protective vaccines for humans for the tick-borne diseases; consequently avoiding tick bites is the best disease-prevention strategy. You can find information about Tick Biology for the Homeowner regarding ticks and tick-borne diseases.
Good tick practices include:
1) Careful tick checks when coming in from the field.
2) Proper clothing while in tick habitat. Clothing should be light in color to allow you to spot crawling ticks more easily. Wear closed-toed shoes, socks, long pants, and a long-sleeved shirt. Tuck pant legs into the socks and the shirt into the pants in order to slow crawling ticks.
3) Use repellants, according to manufacturer directions. Permethrin, DEET, Picaridin
