To prevent ticks from getting under pants, you should tuck cuffs into the socks or shoes. Tuck long hair under a hat. Also, tick repellents can be applied to the outside of clothes, especially the pants. Do visual inspection of your clothes and body twice a day when in tick-infested areas. The larvae and nymphs of ticks are quite small and can be easily mistaken for freckles or dirt.
Ticks like to feed on the back of the head at the base of the skull.
It is a good idea to have another person check for ticks in places you cannot easily see. All clothing should be washed in warm water and detergent. If your pets accompany you to the woods, check them too. If you are having problems with rodents or other wild animals, such as raccoons or opossums, take measures to exclude them from your house or yard. Also, keep shrubs trimmed along the paths near your home.
