While tick bites are not often painful, they can lead to infections or even chronic illnesses like Lyme disease. If you're uncertain whether you're dealing with a tick infestation, check for defining features that distinguish a tick from other bugs. Some bugs that look like ticks are harmless, but ticks must be dealt with immediately to avoid illness or infection. Call an exterminator if you're still not sure for a professional opinion.

Checking for Distinctive Tick Features

  1. Before a tick is engorged with blood, its body is shaped like an oval with 2 major segments. After a tick is engorged, its head will remain small but its body will grow round and plump. [1] [2]
  2. How large a tick is when you find it depends on whether it has recently fed on blood. Before it has drunk any blood, a tick will be around the size of a pinhead. Immediately to several hours afterward, a tick will grow to around the size of a lima bean. [3]

  3. In most cases, ticks have a hard exoskeleton. These are called hard or "authentic" ticks and are usually what people are talking about when describing ticks. Soft ticks with a flexible exoskeleton exist but are only found in select areas. [4]
    • Soft ticks are found in the western United States and southwestern Canada. [5]
  4. Lone star ticks have a white, star-shaped design on their exoskeletons. If a bug does not have this design, it still may be a tick. This pattern is just a defining feature of this tick species. [6]
  5. Black-legged ticks, as suggested by their name, have legs that are darker than their bodies. Like a lone star tick's black legs, this is a defining characteristic of black-legged ticks and may not be present on every tick. [7]

Differentiating Between Ticks and Other Bugs

  1. Ticks do not have wings, nor do they have antennae. If you have found a bug with either, it is not a tick. Research bugs with similar characteristics to ticks but with wings or antennae if your bug in question has these.
    • Poplar weevils, which are commonly mistaken for ticks, have both wings and antennae. [8]
  2. Because ticks are a type of arachnid, like spiders and scorpions, they have 8 legs. [9] If your bug has 6, it is an insect and therefore not a tick. [10]
    • If your bug has less than 6 or more than 8 legs, it is neither an insect nor arachnid but is, regardless, not a tick.
  3. Billbugs are the commonly mistaken for ticks because of their near-identical appearance. The way to distinguish between a tick and a billbug is to watch them. Billbugs swarm in groups, whereas ticks are usually alone. Ticks also feed on blood, whereas billbugs do not. [11]
    • As a general rule, billbugs do not hang around or on people and animals. Ticks often do.
  4. Both ticks and bed bugs hang around animals and humans. Their method of feeding off of people and animals, however, differs. Ticks burrow into the skin to drink a living creature's blood but bed bugs stay on the skin's surface.
    • Make sure you know whether a bug is a tick or bed bug before removing it from your skin. Without proper precautions, you may remove a tick's body while its head remains lodged in your skin.

Identifying Tick Bites

  1. Tick bites are not usually painful. If you experience sharp pain, you have not likely been bitten by a tick. Research your other symptoms to determine what insect or arachnid bit you and begin treatment.
    • If a soft tick bites you, you might notice localized pain immediately after the tick drops off. [12]
  2. Although tick bites are not painful, they can still set off your body's immune system. If the bite and the skin surrounding it looks reddish, it may be a tick bite. Keep in mind, however, that redness is a symptom of many bug bites.
  3. While not often a symptom of tick bites, you may develop a rash if your tick bite becomes infected or if you contracted an illness from the tick bite. If a rash spreads from your tick bite to other parts of your body, call your doctor or visit an urgent care clinic. [13]
    • Some illnesses that ticks carry, like Lyme disease, can take months or years before symptoms develop. [14]
  4. Because tick bites usually do not hurt, the most common way to spot a tick bite is to see the tick burrowed in your skin. Compare the bug on your body to other insects before removing it so you can use a pair of tweezers or a credit card to safely get it out of your skin. If you are not careful, tick heads can remain lodged in your skin. [15]
  5. While most tick bites can be treated at home, you may need emergency care if you develop an infection or allergic reaction. Seek emergency medical help immediately if you notice any of the following symptoms: [16]
    • Raised red bumps (hives) all over your body
    • Trouble breathing
    • Swelling of the mouth, lips, tongue, or throat
    • Lightheadedness, dizziness, or loss of consciousness

      Warnings

      • If you have identified a bug on your body as a tick, do not remove it with your hands. Its head may detach from its body and stay in your skin, which can cause infections. Research how to remove it properly before you try.
        Thanks

      About This Article

      Article Summary X

      To identify a tick, look for a small, oval-shaped, black or brown bug that has 8 legs. Ticks don't have wings or antennas, so if you find a bug with either, it won’t be a tick. Ticks may also have a white, star-shaped design on their backs, but this is only a feature of 1 common breed of tick. Many ticks also have black legs, but not all of them. In general, ticks travel alone, so if you spot other bugs around it, it’s probably not a tick. For more tips, including how to identify a tick bite, read on.
