Ticks are non-insect arthropod arachnids closely related to spiders, scorpions, and mites. They are important to humans because they feed on animals and can pass diseases to people, pets, wildlife, and livestock. In Montana, ticks are capable of transmitting several tick-borne illnesses to people:

Tick close-up

Ticks crawl up on low vegetation and wait for people or animals to pass by and brush up against them. Ticks are attracted to the odor, heat, and breathing of people and other animals. They attach themselves to the host by stretching their legs out towards the host and do not jump or fly. Ticks have 8 legs for crawling slowly and then holding on and no wings. In Montana, tick season lasts from the onset of warmer weather in the spring until about mid-July when warmer weather and low relative humidity cause the ticks to become inactive.

Engorged ticks
