What are the common ticks?

Types of Ticks

Ticks are actually arachnids (the 8-legged class that includes spiders) and are found around the world. These are some of the common ticks in the US:

  • Deer Tick (Ixodes scapularis, Blacklegged tick)
  • American Dog Tick (Dermacentor variabilis)
  • Lone Star Tick (Amblyomma americanum)

Tick life cycle
Ticks have four stages - the adults are tiny, but the larvae and nymphs are even smaller:

  • Eggs
  • Larva (0.7 - 0.8 mm)
  • Nymph (1 - 2 mm)
  • Adult (~ 6 mm)
