Ticks are external parasites, living by feeding on the blood of mammals, birds, and sometimes reptiles and amphibians. The timing of the origin of ticks is uncertain, though the oldest known tick fossils are from the Cretaceous period, around 100 million years old. Ticks are widely distributed around the world, especially in warm, humid climates.
The ticks that transmit Lyme disease are hard ticks. [4] Ticks often have a preferred host, but may still attach to a different host when called for. Their preferred host may change depending on the tick's stage of development (eg larval vs adult) and the host may or may not carry the transmittable pathogen. [3]

A tick bite does not automatically transfer diseases to the host. Instead, the tick must be attached to the host for a period of time, generally 6–8 hours [9] but sometimes as little as 3–6 hours, [10] before it is capable of transferring disease. The earlier the tick is removed from a host, the less likely it is to contract the illness.
