This is not medical advice. IdentifyThis.app is an AI information tool, not a medical device — results can be wrong and are never a diagnosis. Always consult a qualified healthcare professional about any health concern. If this is an emergency, call 911 (US) or your local emergency number.
Found an attached tick? Remove it promptly with fine-tipped tweezers, grasping as close to the skin as possible and pulling straight up — don't twist, burn, or coat it. Save the tick in a sealed bag for identification.
How to Tick Identifier by Picture
Follow these simple steps to get instant AI-powered identification
Take a clear, close-up photo of the tick — on skin, clothing, a pet, or a white surface. Sign in with Google to access the tool, then upload your image directly from your device. The better the lighting and focus, the more accurate your identification will be.
Our advanced AI examines key identifying features: body shape, color patterns, leg count, scutum (hard plate), mouthparts, and size. It cross-references these features against a comprehensive database of tick species found worldwide. The analysis takes just seconds to complete.
Receive a full identification report including species name, geographic range, potential disease associations (such as Lyme disease, Rocky Mountain spotted fever, or ehrlichiosis), and recommended next steps. Our results go beyond a simple label — you get actionable, contextual health and safety information.
Alternative Methods
Local Health Department Submission
Many county and state health departments offer free tick identification services where you can mail in or drop off a tick for expert examination. This method can take several days but may include laboratory testing for pathogens.
University Extension Programs
Land-grant universities and agricultural extension offices in many states offer tick ID services, sometimes free of charge, especially during peak tick season. They can provide species-level identification and regional disease risk context.
Physician or Veterinarian Consultation
If a tick has been attached to a person or pet, a medical professional can both identify the tick and assess risk factors for tick-borne illness. They can also prescribe prophylactic treatment when appropriate.
Tick Encounter Apps (TickEncounter)
The TickEncounter Resource Center at the University of Rhode Island offers a tick identification tool online specifically for public health purposes. It provides species ID and risk assessment based on photographs and reported geographic location.
Physical Field Guides
Printed guides such as 'Ticks of the United States' or regional entomology field manuals provide detailed morphological keys for identifying tick species by observable characteristics. These are best used by those with some entomology background.
Photo Quality Tips
- ✓Place the tick on a plain white or light-colored surface before photographing to maximize contrast and visibility of body markings.
- ✓Use your camera's macro mode or move as close as possible without blurring — tick bodies are tiny and detail is critical for accurate species identification.
- ✓Ensure strong, even lighting from the front; avoid harsh shadows that can obscure the scutum, leg color, or body shape.
- ✓Photograph from directly above (dorsal view) as well as from the side if possible — multiple angles significantly improve AI accuracy for tick ID.
Best Practices
- •Do not crush or damage the tick before photographing — intact specimens yield far better identification results.
- •Include a size reference like a coin or ruler in at least one photo to help gauge the tick's actual size, which is an important identification factor.
- •If the tick is still attached, photograph it carefully without disturbing it, then use proper removal technique (fine-tipped tweezers) before submitting more detailed photos.
- •Take the photo in natural daylight or under a bright lamp — color accuracy matters for distinguishing species like the lone star tick (white dot) from similar-looking species.
What Can Our Tool Recognize?
AI-powered recognition across multiple categories with high accuracy.
Identify Ixodes scapularis and Ixodes pacificus, the primary vectors of Lyme disease in North America, by their characteristic dark legs and reddish-orange body.
Recognize Amblyomma americanum by the distinctive white spot on the female's back, associated with ehrlichiosis, STARI, and alpha-gal syndrome.
Identify Dermacentor variabilis, a common tick that transmits Rocky Mountain spotted fever and tularemia, recognizable by its mottled gray-white markings.
Distinguish Dermacentor andersoni, the primary vector of Rocky Mountain spotted fever in the western US, from similar species by geographic context and markings.
Identify Rhipicephalus sanguineus, the only tick capable of completing its entire life cycle indoors, a global pest that can transmit canine ehrlichiosis and spotted fever.
Identify soft-bodied ticks in the Argasidae family, including Ornithodoros species associated with tick-borne relapsing fever, which differ dramatically in shape from hard ticks.
Identify invasive species like Haemaphysalis longicornis (Asian longhorned tick), now established in the eastern US, and other non-native tick species of growing concern.
Why Choose Our Identification Service?
The most accurate, fast, and privacy-focused identification tool available online.
Unlike tools that simply return a species name, our AI provides detailed information about disease associations, attachment duration risk, and recommended medical actions for each tick identified. You get the context you need to make informed health decisions.
IdentifyThis.app is fully web-based, meaning you can identify a tick from any phone, tablet, or computer without downloading anything. This is especially valuable in urgent situations when every second counts.
Beyond ticks, IdentifyThis.app identifies plants, mushrooms, insects, rocks, snakes, dogs, cats, and hundreds of other categories — all in one place with a single subscription. No need to juggle multiple apps.
At just $3/week or $10/month, IdentifyThis.app costs a fraction of competitors — PictureThis charges $39.99/year and iNaturalist-based tools vary widely. Your first identification is always free, and unlimited access is accessible to everyone.
Your uploaded tick photos are not stored or used to build advertising profiles. We process your image for identification and that's it — important when photos may contain personal health information or images of your body.
Whether you're hiking in the Appalachians, camping in the Pacific Northwest, or traveling internationally, IdentifyThis.app works on any internet-connected device. Tick awareness is a global health need, and our tool serves users everywhere.
Our AI is trained to recognize subtle morphological differences between tick species — body shape, scutum patterns, leg coloration, mouthpart structure — delivering identification accuracy that goes beyond basic image matching.

One of the most common tick-related searches, people upload photos after finding a tick on themselves, a child, or a pet to quickly determine species and risk level. Our AI provides immediate species identification with health context to guide next steps.
Deer ticks (black-legged ticks) are the most medically significant ticks in North America due to their role in Lyme disease transmission, making accurate identification critical. Users often need to distinguish deer tick nymphs — which are tiny and easily confused with other small ticks — from less dangerous species.
Beyond species identification, people urgently want to know whether the tick they found poses a disease risk, how long it may have been attached, and whether medical attention is warranted. Our results include disease association data and recommended next steps for each identified species.
Pet owners frequently discover ticks on their dogs or cats and need to quickly identify the species to assess risk to the animal and potentially to human household members. Our tick identifier works for ticks on pets just as well as those found on people or in the environment.
Many people mistake the American dog tick or brown dog tick for the more dangerous deer tick, leading to unnecessary anxiety or, conversely, false reassurance. Our AI clearly distinguishes between species and explains key visual differences.

When to See a Doctor
AI identification is a starting point, never a substitute for professional medical care. Seek help in these situations:
- Fever, severe headache, or a spreading rash within 30 days of a tick bite — mention the bite to your doctor
- A circular 'bullseye' rash (erythema migrans) anywhere on the body — classic early Lyme disease sign
- Facial drooping, joint swelling, or heart palpitations after a known tick exposure
- Tick attached for more than 24–36 hours, or you can't tell how long
- Bite occurred in a high-risk region for Lyme or Rocky Mountain spotted fever
- You couldn't remove the entire tick (mouthparts left in skin)
