Genus Dermacentor is a classification of hard ticks that live worldwide. These ticks present a threat to human and animal health as they are capable of transmitting serious diseases, such as Rocky Mountain spotted fever and Lyme disease. Synonyms for the Genus Dermacentor include "hard-bodied ticks," "cattle ticks," "wood ticks," and "dog ticks." They are characterized by their hard exoskeleton and their preference for attaching themselves to large mammals. To prevent tick bites, it is important to wear protective clothing and use a tick repellent when outdoors in tick-infested areas. It is also crucial to carefully inspect the skin for ticks after spending time outdoors.
