Other ticks such as wood and dog ticks are usually much larger. Most of the time there is little risk from the bite of a tick. The usual reaction is nothing more than a raised skin bump, which gets better within a few days. Occasionally, ticks can transmit infections to humans. A bite from other ticks, such as the wood tick, the dog tick, or the black-legged deer tick may cause Rocky Mountain Spotted Fever or, in extremely rare cases, a form of paralysis.
Prevention is the best course of action.
Avoid wooded areas. If you work in your garden or in wooded areas, make sure you wear long stockings or pants and shoes. If you spend time in areas that have ticks, you should always do a careful exam of your entire body to check for ticks. If a tick bites you, try to remove it by grasping the head with tweezers and then gently pulling. Avoid crushing the tick because it then may become difficult to remove.
