If you are going to be in areas that may be tick infested, there are several ways you can protect yourself.
Wear light colored clothing so ticks can be spotted more easily, and removed before attachment
Wearing long sleeved shirts and pants tucked into socks or boot tops can be helpful in keeping ticks from reaching your skin
Ticks are usually located close to the ground, so boots or shoes and not sandals, are recommended
Applying insect repellants such as DEET (n,n-diethyl-m toluamide) to clothes and exposed skin, and applying Permethrin (which kills ticks on contact) to clothes can reduce the risk of tick attachment
DEET can be used safely on children and adults, but should be applied according to label guidelines.
