In general, ticks don’t have a lengthy lifespan, but it is enough time for them to wreak havoc on their host. Ticks transmit pathogens that cause disease through the process of feeding. When the egg hatches, a six-legged larva emerges. This mortality is highest for the larvae which are easily killed by the immune reactions in the host's skin.
