General Information On The Different Types of Ticks

There are numerous types of ticks to be aware of. Learn more about the different species of ticks that you may have to deal with.

There are roughly 850 species of ticks around the world, but only 90 of them are found in the United States. Of these, a handful are considered dangerous by the Centers for Disease Control, because of their ability to transmit diseases to people. There are numerous types of ticks found across the country, and they fall into two categories: hard-shell ticks and soft-shell ticks.

Hard-shell ticks

These tick types belong to the family Ioxidae, and undergo three main life stages: larval, nymph and adult. They require one blood meal for each life stage, which is why they are often called "three host ticks." A tick may take up to three days to finish a blood meal, before detaching from the host. The blood causes their bodies to distend during a feeding. Their life cycle can take between 90 days to three years to complete. This type of tick can usually be found in wooded, brush-filled areas, or in areas where there are tall grasses and weeds. Females are larger than males, and may have different coloration. The mouthparts of these types of ticks are usually visible. Most species of hard-shell ticks are diurnal, seeking out hosts to feed on during the day. A female lays 3,000 to 8,000 eggs in one large batch, after which she dies. Here are some common types of hard-shell ticks:

  • American dog tick: Also known as a wood tick, they are a reddish-brown. They are found across the United States, predominately east of the Rocky Mountains and along the Pacific coast. They are known to transmit Rocky Mountain spotted fever and tularemia. The name comes from their preference for feeding on dogs in their adult stage.
  • Blacklegged tick: Also known as the deer tick, or Lyme disease tick, these reddish-brown insects have black legs. They are found in both the Northeastern and Midwestern U.S. These ticks are a cause for concern as infected ticks spread Lyme disease, babesiosis and anaplasmosis. To transmit Lyme disease, the disease itself has to be present in rodent populations that the ticks feed on. The Western blacklegged tick is found on the Pacific coast.
  • Brown dog tick: True to their name, these ticks are brown, and are usually found on dogs. They are widespread across the U.S. and transmit Rocky Mountain spotted fever.
  • Gulf Coast tick: These light brown ticks are found in states along the Gulf of Mexico and the Atlantic Coast. They are usually found on birds, rodents and livestock, but can transmit spotted fever strains to people.
  • Lone star tick: These ticks are brown, with a visible white patch on their backs. They are found in the Eastern and Southeastern U.S. A common host for them is the white-tailed deer. They are known to transmit tularemia, ehrlichiosis and STARI (Southern Tick Associated Rash Illness) to people.

Soft-shell ticks

These ticks belong to the family Argasidae. They also undergo three stages of development, but it is hard to distinguish between stages because they have multiple nymphal molts. Soft-shell ticks require several blood meals for each stage, and feed for a few minutes to a few days, depending on the host. Their skin, which appears leathery, will stretch, but not distend during a meal. They have a slower life cycle, taking up to two years to mature for most species, and can live up to a decade. Their mouthparts are located on their underside and are not visible. These types of ticks are usually found in animal burrows, nests or caves. Males and females are about the same size and coloration. Soft-shell ticks are primarily nocturnal. Females will lay multiple, small batches of eggs, typically after each blood meal. Soft-shell ticks are able to go up to a year without a blood meal before dying of starvation. Here are some common types of soft-shell ticks:

  • Common fowl tick: Also known as chicken ticks, poultry ticks and blue bugs. These reddish-brown to dark brown ticks are often found where chickens or turkeys are raised, especially when there are wooden structures used to house the fowls.
  • Relapsing fever ticks: These ticks carry the bacterium that causes tick-borne relapsing fever. They are found in rodent-infested areas, most often in cabins with a rodent problem. Some species of this tick can live for up to 10 years, and bites are not easily seen or felt by the host.

Now that you know about the different types of ticks, you can be on the lookout for them in your home and yard. If you find these pests, call a pest management professional to help you detach them from where you live.
