Ticks 

 Ticks are arachnids, typically 3 to 5 mm long. Ticks are external parasites, living by feeding on the blood of mammals, birds, and sometimes reptiles and amphibians.

 The American Dog Tick can be found across the continent on dogs, coyotes, bears and any other warm-bodied host that happens to walk by. While some ticks carry the bacterium that are known for causing Lyme disease in humans the Dog Tick is not one of them.

The American Deer Tick or black-legged tick, is known in some parts of the US as the bear tick. It is a hard-bodied tick found in the eastern and northern Midwest of the United States as well as in southeastern Canada. It is a vector for several diseases of animals, including humans (Lyme disease, babesiosis, anaplasmosis, Powassan virus disease, etc.) and is known as the deer tick owing to its habit of parasitizing the white-tailed deer.
