How to Remove a Tick Safely

Before you start

Gather your materials before you start: fine-tipped tweezers, rubbing alcohol or an iodine scrub, and a small, dry, sealable container or plastic bag. Fine-tipped tweezers are not the same as the blunt-tipped household or eyebrow tweezers in most bathroom drawers. Broad tools will compress the tick's body instead of isolating the head [Source: CDC].

Fine-tipped tools avoid compressing the tick's abdomen (technically the alloscutum). Squeezing the body acts like a piston, raising hydrostatic pressure in the tick's gut. That mechanical force can push infectious fluids and pathogens (including Borrelia burgdorferi, the agent of Lyme disease) from the tick's midgut directly into your bloodstream [Source: CDC].

Don't try folk methods. Never use lit matches, petroleum jelly, nail polish, or essential oils to make the tick let go [Source: CDC]. These irritants don't cause the tick to back out voluntarily. They cause respiratory distress or thermal shock, and the stress response is for the tick to regurgitate its infectious gut contents and saliva into the wound. That dramatically accelerates transmission risk [Source: CDC]. Skip the specialized twisting tools too. Twisting often severs the mouthparts and leaves them embedded in the skin [Source: UMaine Cooperative Extension].

Step 1: Grasp the tick close to the skin

Hold your fine-tipped tweezers parallel to the skin. Place the tips directly above the point where the tick's mouthparts (gnathosoma) enter the skin. Your goal is to grasp the tick as close to the skin's surface as possible [Source: CDC].

Do not grasp or squeeze the tick's body. Pressure on the midsection significantly raises the risk of mechanical pathogen transfer [Source: CDC]. Stay focused on the mouthparts right at the skin, and you avoid the piston effect that forces infected fluids into the bite.

Step 2: Pull straight upward with steady, even pressure

Once the tweezers are seated around the mouthparts, apply steady, continuous upward pressure. The motion has to be linear and perpendicular to the skin. Do not twist, jerk, or rock the tick. Linear tension lets the backward-facing barbs on the tick's feeding tube disengage gradually [Source: CDC]. Twisting introduces lateral shear forces that can snap the mouthparts and leave them embedded in the skin [Source: UMaine Cooperative Extension].

If the mouthparts break off, make one gentle attempt to remove the fragments with your tweezers. If they don't come out easily, leave them alone and let the skin heal. Retained mouthparts are non-viable chitinous structures. They don't contain salivary glands or midgut tissue, so they can't transmit disease. Your body will eventually push them out as the wound heals [Source: CDC].

Step 3: Clean the bite area and your hands

Once the tick is out, sanitize right away to prevent a secondary bacterial infection at the site. Clean the bite, your hands, and the tweezers thoroughly with rubbing alcohol, an iodine scrub, or soap and warm water for at least 20 seconds [Source: CDC]. Sanitizing the tools also prevents cross-contamination if you use them again later.

Step 4: Save or kill the tick correctly

Once the tick is out, handle it properly so it can't re-attach and so you don't expose yourself to its pathogens.

To kill the tick. If you don't plan to have it tested, dispose of it by submerging in rubbing alcohol, sealing it in a bag, wrapping it tightly in tape, or flushing it down the toilet [Source: Alpha-gal Information]. Never crush a tick with bare fingers. Pathogens in its internal fluids can enter your system through tiny abrasions in the skin [Source: CDC].

To save the tick. Preservation is recommended in Lyme-endemic areas or for high-risk bites. Seal the tick in a dry, crush-proof container or plastic zipper bag. Label it with the date of extraction and the location of the bite on your body. Store in the refrigerator if it's alive, or the freezer if dead, to preserve its DNA for testing [Source: Alpha-gal Information].

Step 5: Mark the date and monitor for 30 days

Document the exact date of the bite and your best estimate of how long the tick was attached. Then monitor closely for 30 days. The incubation period for most tick-borne pathogens runs 3 to 30 days [Source: Penn Medicine].

Watch for a localized rash during this window. The most common indicator of Lyme disease is Erythema migrans (EM). This rash typically appears at the bite site and is round or oval-shaped. It often shows up as a bull's-eye with a clear center, but it can also be a solid red or purple disc [Source: Penn Medicine]. The rash is absent in 20 to 30% of confirmed Lyme cases, so a lack of rash does not mean you're in the clear.

Watch for systemic signs of infection too: fever, chills, fatigue, headache, muscle or joint pain, swollen lymph nodes [Source: CDC]. Neurological symptoms (facial palsy, severe neck stiffness) require immediate medical attention. If a rash appears, photograph it with a date.

When to seek medical care

Get a professional medical evaluation if any of these red flags or risk criteria apply:

• A rash appearing at the bite site within 30 days, especially if it expands.
• Fever, chills, or persistent body aches within 30 days of the bite [Source: CDC].
• The tick was attached for more than 24 hours in a Lyme-endemic region.
• The tick was identified as a black-legged (Ixodes scapularis) tick.
• You can't remove the tick yourself.
• Any unusual symptom in the 30 days after the bite, even if you're not sure it's related.

For high-risk exposures, a provider may prescribe post-exposure prophylaxis (PEP), typically a single 200mg dose of doxycycline. CDC and IDSA guidelines recommend this treatment only when all of the following criteria are met [Source: Penn Medicine]:

• Identified adult or nymphal Ixodes scapularis.
• Attached for at least 36 hours (based on engorgement or observation).
• Treatment started within 72 hours of removal.
• Local tick infection rate is 20% or higher.
• No medical contraindications exist.

What if the tick was on my pet?

If you find a tick on a dog or cat, the removal technique is the same as on a human. Use fine-tipped tweezers to grasp the mouthparts close to the skin and pull upward with steady, linear pressure.

Monitor your pet for two to three weeks for non-specific signs of illness: lethargy, loss of appetite, fever, or shifting-leg lameness (joint pain that moves from one limb to another). Pets don't develop the bull's-eye rash you see in humans. If you notice changes in your pet's energy or gait, get them to a vet right away. Pets need specialized diagnostics, and a human physician isn't the right person to treat them.
