The answer to 'what causes tick' is ticks are small, parasitic arachnids that feed on the blood of humans and animals. Ticks are commonly found in wooded, grassy, or brushy areas and can transmit various diseases, including Lyme disease, Rocky Mountain spotted fever, and ehrlichiosis. Ticks are attracted to their hosts by detecting breath, body odor, body heat, and vibrations.
Ticks often wait on the tips of grasses and bushes, known as 'questing,' and then latch onto a passing host. Once attached, they burrow their mouthparts into the skin and begin feeding on the host's blood. Ticks can remain attached and feeding for several days, increasing the risk of disease transmission.
