Some ticks are notorious for carrying the bacterium that causes Lyme Disease in humans. The American Dog Tick is NOT one of them. It is not entirely harmless though. American Dog Ticks may carry Rocky Mountain Spotted Fever and Tularemia, two serious diseases that can adversely affect humans. Both list a high fever as a symptom, but individuals may vary in a variety of other symptoms connected to these illnesses. Bite wounds associated with Tularemia may form a skin ulcer (gaping wound). Both diseases can be successfully treated with antibiotics when diagnosed early, so it is important to contact a physician immediately if bitten.
Ticks are 8-legged arachnids though they are not spiders. They do not have wings and cannot fly, but they are adept at latching on to clothes, fur and hair that wisps past them within their reach. The American Dog Tick is also known as a Wood Tick. It happens to be spotted most often on dogs coming in from frolicking in the woods, so it has become most familiar as a parasite of that particular animal. The American Dog Tick, however, will feed on just about any animal it can hook its legs onto. After curling their legs around fabric or fur, the tick moves toward the skin. It then crawls to warmer parts of the body like armpits and inner thighs. There, it bites into the flesh while using a numbing agent in its saliva that renders the puncture imperceptible. It is then able to suck the blood from its host unhindered until it is fully engorged and more than double its original size.

* MAP NOTES: The territorial heat map above showcases (in red) the states and territories of North America where the American Dog Tick may be found (but is not limited to). This sort of data is useful when attempting to see concentrations of particular species across the continent as well as revealing possible migratory patterns over a species' given lifespan. Some insects are naturally confined by environment, weather, mating habits, food resources and the like while others see widespread expansion across most, or all, of North America. States/Territories shown above are a general indicator of areas inhabited by the American Dog Tick. Insects generally go where they please, typically driven by diet, environmental changes, and / or mating habits.
