The Rocky Mountain wood tick is a common tick species found in the western United States and parts of Canada. It typically inhabits grassy and wooded areas, where it waits for a host to pass by. This tick is known for its distinctive brown color and can grow up to 1/4 inch in size when fully engorged with blood. These ticks are important to monitor because they can transmit diseases such as Rocky Mountain spotted fever and tick-borne encephalitis. They are most active during the spring and early summer months, making it essential for outdoor enthusiasts to take precautions against bites while enjoying nature.
