The short version
Identify the tick you found because different species carry different diseases: blacklegged ticks carry Lyme, lone star ticks carry ehrlichiosis and alpha-gal, and American dog ticks carry Rocky Mountain spotted fever and tularemia. Save the tick and photograph it.
- Which tick matters — different species carry different diseases.
- Blacklegged ticks carry Lyme; lone star and dog ticks carry other illnesses.
- Save the tick and photograph it if you can.
- Tell a doctor about any tick bite and any rash or fever that follows.
For anyone who has found a tick and wants to know what it was and what to watch for.
What to look for
Guessing wrong either causes needless worry or misses the disease that actually matters. Identification — from a photo or a saved specimen — is the first step. A blacklegged tick and a dog tick need different follow-up.
- 1Ticks on pets after walks or time outdoors.
- 2Ticks on clothing or skin after yard work.
- 3A tick found indoors or on pet bedding.
- 4Deer, mice, or other wildlife passing through the yard.
- 5Tall grass, leaf litter, or brush at the yard edge.
- 6Stone walls, woodpiles, or brush near play areas.
Why it’s worth acting soon
- Tick-borne illness for people and pets.
- More ticks each year as wildlife and hosts move through.
- Brown dog ticks can establish indoors and are hard to remove.

Mulch beds and shady borders next to the lawn are worth checking first.Why identification changes the follow-up.
A blacklegged tick means watching for Lyme, anaplasmosis, and babesiosis; a lone star tick means ehrlichiosis and alpha-gal syndrome; an American dog tick means Rocky Mountain spotted fever and tularemia. The whole point of identifying the tick is the follow-up. Naming the species tells you which symptoms to watch for and what to tell a doctor.
When you're not sure.
Take a clear photo, save the tick in a sealed bag or container, and check your state or county health department's tick page. If the person bitten develops a rash or fever within weeks, tell a doctor — and mention the tick.
Ticks wait on grass and brush with their front legs out, ready to grab a passing person or pet.The blacklegged tick's three life stages.
- Nymphs are poppy-seed sized, feed in late spring and summer, and cause the most Lyme infections because people miss them. - Larvae have six legs and rarely carry Lyme yet — they pick it up when they feed. - A blacklegged tick passes through three stages, and the risk changes with each. - Adults feed in fall and spring and are easier to see but still small. The stage matters because a tiny nymph is the bite you're most likely to overlook.
A species-by-species field guide.
- American dog tick: larger and brown, with mottled light markings. It carries Rocky Mountain spotted fever and tularemia, broadly east of the Rockies. - Lone star tick: reddish-brown with a single white dot on the female's back. It carries ehrlichiosis and alpha-gal syndrome, mostly in the Southeast and South Central. - Blacklegged tick: small and dark with no light markings; females have a reddish-brown body and dark legs. It carries Lyme disease, anaplasmosis, and babesiosis, mostly in the Northeast and Upper Midwest. - Here's how to tell the common U.S. ticks apart, species by species. - Brown dog tick: reddish-brown, and the one species that can complete its life cycle entirely indoors, tied to dogs and kennels. The markings are easiest to see on a clear photo, so photograph first and identify second.
Where each species lives.
Blacklegged ticks dominate the Northeast and Upper Midwest, lone star and Gulf Coast ticks the Southeast and South Central, Rocky Mountain wood ticks the mountain West, and western blacklegged ticks the Pacific Coast. If you're not in a species' range, you don't need to worry about it — check your state or county health department.
The regional disease map.
cases come from there. The Northeast and Upper Midwest are Lyme country — blacklegged ticks carry Lyme, anaplasmosis, and babesiosis, and most U.S. The disease risk follows the region. Know your region's list and you know what to watch for. The Mountain West adds Colorado tick fever. The Southeast and South Central are lone star country — ehrlichiosis and alpha-gal syndrome, plus Rocky Mountain spotted fever from dog ticks.
When to treat an unknown tick as risky.
If you can't identify a tick, the safest default is to treat it as potentially disease-carrying: remove it promptly, save it, and watch for symptoms. Identification matters, but it's the fast removal and the follow-up watch that actually protect you.
Size, color, and stage.
A larger reddish-brown tick with a single white dot is a lone star. A poppy-seed-sized tick is a nymph — the stage responsible for most Lyme infections, so take it seriously. Use size and color as rough field marks. These aren't definitive, but they get you to the right page of the guide. A small, dark tick with no light markings is likely blacklegged.
Photographing for identification.
A clear, zoomed-in photo of the whole tick — taken in good light with the top of the body visible — is usually enough for a professional or your state health department to identify it. Take the photo before you remove or discard the tick, and keep the specimen in a sealed bag in case it's needed later.
What affects the price
- Size and terrain of the yard edge being treated.
- Number of visits timed to spring and fall peaks.
- Whether tick tubes or deer/rodent host management is included.
- Access difficulties like steep slopes or dense brush.
- Presence of stone walls and rock piles.
- Monitoring and drag counts after treatment.

What is your biggest concern about ticks?
When to call for help
Call a professional if you keep finding ticks on people or pets, or if your yard backs onto woods, brush, or tall grass. A pro can find the hot spots and time edge treatments to the spring and fall peaks.
What you can do yourself
Most of tick control is yard work you can do yourself: mow, rake leaf litter, and add a wood-chip barrier at the edge. A professional adds targeted edge treatments and drag sampling to confirm where ticks actually are.
Where you live matters
Tick risk is regional — species and disease risk vary by where you live. Identify the tick, learn the local species, and check your state or county health department. The most useful first step in Tick Identification is to note where you have seen ticks activity and when it appears, so an inspection is faster and the quote more accurate. In Tick Identification, checking the usual entry points, moisture spots, and sheltered areas near the structure usually turns up the conditions that are letting them in. A local provider who knows Tick Identification can point out the specific things that matter most here before you commit to a plan. In Tick Identification, before you book, ask whether the inspection is included, what the treatment plan covers, how many visits to expect, and what the written quote includes. In Tick Identification, getting the scope, the prep steps, and any follow-up terms in writing makes it much easier to compare providers fairly, and a good provider will walk you through each of these without pressure.
Simple ways to keep ticks away
- Mow regularly and keep grass short.
- Rake and remove leaf litter from high-use areas.
- Add a 3-foot wood-chip or gravel strip between lawn and woods.
- Keep play sets and seating away from the yard edge.
- Use vet-approved tick prevention on pets.
- Shower within a couple of hours of coming inside.
- Dry clothes on high heat to kill any ticks they picked up.
Treatment focuses on edges, shrub beds and shady borders, not the open lawn.Did you know?
Larval ticks have six legs; nymphs and adults have eight.
Opossums groom off and eat most of the ticks that try to feed on them.
Ticks don't jump or fly — they wait on vegetation with their front legs out, ready to grab a passing host.
Questions people ask
How do I tell a blacklegged tick from a dog tick?
Blacklegged ticks are smaller and darker with no light markings; dog ticks are larger and brown with mottled light areas. When in doubt, save it and check with your health department.
Should I keep the tick after removing it?
Yes, if you can — a saved tick in a sealed bag lets a professional or lab confirm the species if symptoms develop.
Do all ticks carry Lyme disease?
Other ticks carry different diseases. Only blacklegged ticks (and, in the West, western blacklegged ticks) transmit Lyme. No.
Does the size of the tick matter?
It tells you the life stage. Nymphs are tiny and easy to miss, and they're responsible for many Lyme infections because they're overlooked.
Which tick carries Lyme disease?
The blacklegged tick in the East and the western blacklegged tick in the West. Lone star and American dog ticks carry other diseases, not Lyme.
How do I save a tick for identification?
Drop it in a sealed bag with a note of the date and where the bite likely happened, and keep it cool. If symptoms develop, a lab can confirm the species and narrow the risk.
Does the size of the tick tell me the life stage?
Roughly — nymphs are poppy-seed sized and larvae even smaller, while adults are larger. The stage matters because nymphs cause the most Lyme infections.
What does a white dot on the back mean?
A single white dot on the female's back marks a lone star tick — the species that carries ehrlichiosis and can trigger alpha-gal syndrome, a red-meat allergy.
