Always check your entire body after walking through a potentially tick-infested area, as ticks can cause skin infections and more serious diseases. Adult ticks suck blood from hosts by burying their head into skin, but they are often found unattached and can simply be brushed off. Avoid pulling the rear of the body, as this may squeeze the tick's gut contents through the attached mouth parts into the skin, increasing the risk of infection and disease. To remove an attached tick, use a pair of tweezers, grab it by the head and gently pull it straight out - do not twist it. (If no tweezers are available, use your fingers, but protect them from contamination with a piece of paper.) Do not rub oil, alcohol or petroleum jelly on it. If you get sick in the next couple of weeks, consult a doctor.
