Brown Dog Tick
The brown dog tick is unique in that it can complete its entire life cycle indoors. As a result, it is more of a domestic pest (occurring in and around structures) than other tick species. Other ticks can be brought indoors, but they are not able to build populations and infest structures like the brown dog tick. Because it is primarily an indoor parasite of the ever-present domestic dog, it is the most widespread tick in the world. It is usually introduced into a structure on an untreated dog that originated from or visited an infested location.
