Biology and Behavior

Ticks are part of two main families, Ixodidae (hard ticks) and Argasidae (soft ticks), both characterized by their barbed proboscis used for feeding on the blood of warm-blooded animals. Their life cycle typically involves four stages: egg, larva, nymph, and adult.

Ticks locate their hosts by 'questing,' a process in which they perch on the tips of grasses and shrubs with their first pair of legs extended, waiting to latch onto a passing host. They are unable to fly or jump, and thus rely on direct physical contact with their hosts to attach and begin feeding.

Disease Transmission

Ticks are notorious vectors for a number of diseases including Lyme disease, Rocky Mountain spotted fever, and tick-borne encephalitis, among others. They transmit these pathogens to humans and animals during the process of blood feeding.

Tick Prevention and Control

Preventing tick bites is crucial in areas known for tick-borne diseases. This can be achieved through the use of repellents, wearing protective clothing, and performing regular tick checks after being in tick-infested areas.

In terms of control, strategies involve reducing tick habitats (like tall grasses and brush), using pesticides, and managing wildlife that serve as tick hosts.

Etymology and Other Meanings

The term 'tick' is also used in a number of other contexts. It can refer to a light mattress traditionally filled with feathers or down, or it can denote a metallic tapping sound similar to that made by a clock or timer. In the context of lists and record-keeping, a 'tick' often refers to a check mark indicating the completion or acknowledgment of an item. As a verb, 'to tick' can mean to make a clicking or ticking sound, or to mark with a tick or check mark.
