Texas Tick Species: What Bit You Matters
Texas has four tick species that regularly bite humans and pets. Each carries different diseases. Knowing which tick bit you determines what symptoms to watch for and whether you need prophylactic antibiotics.
| Tick Species | Appearance | Diseases It Carries | Texas Range | Peak Season |
|---|---|---|---|---|
| Lone Star Tick (Amblyomma americanum) | Reddish-brown body. Female has a single white spot (the "lone star") on her back. Most common tick in Texas — 90%+ of human tick encounters. | Ehrlichiosis, Southern Tick-Associated Rash Illness (STARI), Alpha-gal syndrome (red meat allergy), Tularemia | Statewide — every county | March-September |
| Blacklegged Tick / Deer Tick (Ixodes scapularis) | Very small — nymphs are the size of a poppy seed. Dark brown to black body with no white markings. This is the Lyme disease vector. | Lyme disease, Anaplasmosis, Babesiosis, Powassan virus | Eastern third of Texas (Piney Woods, Post Oak Savannah) | October-May (cooler months) |
| American Dog Tick (Dermacentor variabilis) | Brown with white or silver markings on the back (scutum). Larger than the deer tick. Most common tick found on dogs in Texas. | Rocky Mountain Spotted Fever (RMSF), Tularemia | Statewide — most of Texas | April-August |
| Gulf Coast Tick (Amblyomma maculatum) | Dark brown with ornate white markings. Found primarily in coastal and southern Texas. | Rickettsia parkeri rickettsiosis (similar to RMSF but milder) | Gulf Coast, South Texas, expanding north | April-October |
How to Remove a Tick: The Right Way (and 5 Ways You Should Never Do)
The CDC and Texas Department of State Health Services agree on exactly one correct removal method:

- Use fine-tipped tweezers (not blunt household tweezers — the fine tips let you grip the tick's mouthparts without squeezing its body).
- Grip the tick as close to your skin as possible — as near to the head/mouthparts as you can get. Do not grab the body.
- Pull upward with steady, even pressure. Do not jerk, twist, or yank. The tick's mouthparts are barbed — twisting can break them off in your skin.
- If mouthparts break off and remain in the skin: try to remove them with the tweezers. If you cannot, leave them alone. Clean the area and let the skin heal. The body will expel them naturally. Digging at them with a needle causes infection.
- Clean the bite area with rubbing alcohol or soap and water.
- Save the tick in a sealed plastic bag with a damp cotton ball or piece of paper towel. Write the date of the bite on the bag. If you develop symptoms later, the tick's species can help your doctor determine which diseases to test for.
The five things you should NEVER do:
- Do NOT burn the tick with a match. This causes the tick to vomit its stomach contents into the bite wound — the fastest way to transmit whatever pathogens it carries.
- Do NOT smother it with petroleum jelly, nail polish, or alcohol. Ticks breathe only a few times per hour. You will die of old age before the tick suffocates. Meanwhile, it is still attached and may regurgitate.
- Do NOT twist it off. The mouthparts are barbed. Twisting breaks them off in your skin.
- Do NOT squeeze the body. This forces the tick's gut contents into the wound.
- Do NOT use your fingers. Use tweezers. Fingers squeeze the body and are less precise.
Lyme Disease in Texas: The Real Risk
Lyme disease in Texas is less common than in the Northeast or Upper Midwest, but it is present. The CDC reports 50-275 confirmed cases per year in Texas, concentrated in the eastern Piney Woods region where the blacklegged tick (deer tick) is established. Most Texas Lyme cases are actually acquired during out-of-state travel to the Northeast — but locally acquired cases do occur, particularly in: Tyler, Longview, Lufkin, Nacogdoches, and the Houston metro area's suburban-woodland interface.

If you were bitten by a tick in East Texas between October and May (peak deer tick activity in Texas), AND the tick was attached for more than 36 hours, AND it was a blacklegged tick — your doctor may prescribe a single dose of doxycycline (200 mg) as prophylaxis. This one-dose regimen is approximately 87% effective at preventing Lyme disease when given within 72 hours of tick removal. This is for deer tick bites only. Lone star tick and dog tick bites do not transmit Lyme and do not warrant prophylaxis.
Alpha-Gal Syndrome: The Tick Disease Most Texans Have Never Heard Of
The lone star tick — Texas's most common tick — can trigger alpha-gal syndrome, an acquired allergy to red meat (beef, pork, lamb) and sometimes dairy products. Symptoms occur 2-6 hours after eating red meat and include hives, swelling, respiratory distress, and in severe cases anaphylaxis. Unlike typical food allergies that appear in childhood, alpha-gal syndrome can develop at any age after a single tick bite. There is no cure. Management is strict avoidance of red meat. Texas has one of the highest rates of alpha-gal syndrome in the US precisely because the lone star tick is so common here. If you develop unexplained allergic reactions hours after eating red meat — especially if you have been bitten by ticks in the past year — tell your doctor to test for alpha-gal IgE antibodies.
When to See a Doctor After a Tick Bite
- Within 72 hours: If the tick was a deer tick attached for more than 36 hours — ask about doxycycline prophylaxis.
- Within 30 days: If you develop any of these symptoms: bullseye rash (erythema migrans — a expanding red ring around the bite site), fever, chills, headache, muscle/joint pain, or fatigue. These are early signs of tick-borne disease and respond well to antibiotics when treated early.
- Any unexplained allergic reaction hours after eating red meat: Ask about alpha-gal testing.
