Tick Bite: What to Do and When to See a Doctor

Finding an attached tick is unsettling, but the right response is straightforward. The most important thing is prompt, proper removal — many tick-borne diseases require hours of attachment before they can be transmitted, so early removal significantly reduces disease risk. Here is a clear, step-by-step guide to what to do.

Step 1: Remove the Tick Properly

Use fine-tipped tweezers — the kind used for splinters, not blunt-nosed cosmetic tweezers. Avoid using your bare fingers if possible.

• Grasp the tick as close to the skin surface as possible — right at the point of attachment
• Pull upward with steady, even pressure — do not twist or jerk
• The goal is to remove the entire tick including the mouthparts embedded in the skin
• If the mouthparts break off and remain in the skin, remove them with clean tweezers if possible; if not, leave them and let the skin heal — this does not increase disease risk

What NOT to Do

• Do not apply petroleum jelly, nail polish, or gasoline to the tick — these methods do not cause the tick to detach and may cause it to release fluids into the bite
• Do not use a lit match or hot object to "burn" the tick off — same concerns apply
• Do not squeeze or crush the body of the tick during removal
• Do not pull with a twisting motion that can break off the mouthparts

Step 2: Clean the Bite Site

After tick removal, clean the bite area and your hands thoroughly with rubbing alcohol or soap and water. Apply a small amount of antibiotic ointment to the bite site as a precaution against secondary infection.

Step 3: Save the Tick

Place the tick in a sealed plastic bag or small container with a moist cotton ball. Note the date it was found. Keeping the tick allows species identification if you later develop symptoms — this information can be helpful to your physician. Some laboratories and health departments offer tick identification and testing services.

Step 4: Note Attachment Time If Known

If you know approximately when you were in tick habitat, estimating the attachment time helps assess disease transmission risk. Most tick-borne pathogens require extended attachment — blacklegged ticks typically need 24 to 48 hours of attachment to transmit Lyme disease bacteria. Lone star ticks and American dog ticks can transmit some pathogens more quickly. If the tick was clearly engorged (fully fed, greatly enlarged), it had been attached for a longer period.

Step 5: Monitor for Symptoms

Watch for these symptoms for 30 days following a tick bite:

• Expanding rash: A rash that expands outward from the bite site — with or without a bull's-eye pattern — is the classic early sign of Lyme disease. Any expanding rash warrants immediate medical evaluation.
• Fever: Fever in the days to weeks after a tick bite is a warning sign. Missouri's most common tick-borne diseases (ehrlichiosis, RMSF) typically produce fever within 1 to 2 weeks of the bite.
• Headache, muscle aches, fatigue: These flu-like symptoms following a tick bite warrant a physician visit, particularly if combined with fever.
• Rash anywhere on the body: The spotted rash of Rocky Mountain Spotted Fever typically appears on the wrists and ankles first and spreads to the trunk. It may initially be subtle — do not dismiss a faint rash after recent tick exposure.

When to Seek Medical Attention Promptly

• Any expanding rash at or away from the bite site — seek care the same day
• Fever within 30 days of a tick bite — call your doctor the same day
• The tick was a blacklegged tick (deer tick) and was attached for more than 24 hours — discuss prophylactic antibiotic treatment with your doctor
• You are in a high-risk group (immunocompromised, elderly, young child) — lower threshold for seeking evaluation
• Any symptoms that are worsening rather than improving

Tick-Borne Disease Treatment

Most tick-borne diseases in Missouri — ehrlichiosis, RMSF, Lyme disease, and anaplasmosis — are effectively treated with antibiotics, particularly doxycycline, when treatment is started promptly. The key word is promptly — RMSF in particular can be rapidly fatal without early antibiotic treatment. Do not wait to see if symptoms resolve on their own if you develop fever after a tick bite in Missouri.
