Many ticks become engorged within 24 hours, according to the nonprofit organization MaineLyme. Seed ticks take about three to 11 days to become completely engorged, notes The Daily Puppy.
Seed ticks embed themselves into the skin of a host animal, feed for several days and then fall off before seeking a second host animal for engorgement, according to The Daily Puppy. Ticks are tiny arachnids that live by consuming the blood of a host animal, including birds, mammals and reptiles, explains Wikipedia. Ticks sometimes carry diseases including Lyme disease, Rocky Mountain spotted fever and Colorado tick fever. Species of ticks are located throughout the world but are more plentiful in humid and warm climates, where they are better able to reproduce.
