Ticks are small arachnids, typically 3 to 5 mm long, part of the order Parasitiformes. Along with Ixodid ticks have three hosts, taking at least a year to complete their lifecycle. Argasid ticks have up to seven nymphal stages (instars), each one requiring a blood meal. Because of their habit of ingesting blood, ticks are vectors.
Hard ticks have only one nymphal instar while soft ticks may have several. Ixodid nymphs commence questing and the entire cycle of host contact, attachment.
