Ticks are more closely related to spiders and scorpions than insects. There are about 200 species in the United States. Ticks live in tall grass or shrubs. They do not jump or fly, although they may drop from their perch and fall onto a host. Ticks can live as long as 200 days without food or water. Ticks feed on the blood of their host; humans, birds, reptiles, and wild and domestic animals. Pets may contract multiple diseases from a single tick bite. TIP: Never remove a tick with your bare hand. Instead, using tweezers, grasp the tick close to the skin and pull gently.
