Tick-bite prevention for people with alpha-gal syndrome

Reviewed by an internal medicine physician in Columbia, Missouri · Last reviewed July 3, 2026 · ~8 min read

For most allergies, avoiding the trigger is the whole job. Alpha-gal syndrome (AGS) has an extra wrinkle: it starts with a tick bite, and new tick bites may reactivate or worsen your reactions. That makes tick-bite prevention part of managing AGS, not just avoiding it in the first place. This CDC-based guide covers repellents, permethrin, tick checks, a simple gear checklist, and how to remove a tick if you find one.

Why prevention matters more with AGS

The CDC notes that new tick bites may reactivate allergic reactions to alpha-gal, so people with AGS are advised to prevent future bites as part of managing the condition. Tick exposure can happen year-round but peaks in warmer months (roughly April–September), and many people encounter ticks in their own yard or neighborhood — not just deep in the woods.

Before you go outdoors

• Know where ticks live. They favor grassy, brushy, and wooded areas. Walk in the center of trails and avoid high grass and leaf litter.
• Use an EPA-registered insect repellent. The CDC points to repellents containing DEET, picaridin, IR3535, oil of lemon eucalyptus (OLE), para-menthane-diol (PMD), or 2-undecanone. Always follow the label. Don't use OLE or PMD on children under 3. If you're also using sunscreen, apply sunscreen first, then repellent.
• Treat clothing and gear with 0.5% permethrin — or buy pre-treated items. Permethrin can be applied to boots, clothing, and camping gear and stays protective through several washings. (Permethrin is for gear, not skin.)
• Dress to spot ticks. Light-colored clothing, long sleeves, and pants tucked into socks make ticks easier to see and harder to reach skin.

After you come indoors

• Check your clothing and tumble-dry on high heat for 10 minutes to kill any ticks on dry clothing (damp clothes need longer; wash in hot water if needed — cold or medium water won't kill ticks).
• Examine gear and pets, which can carry ticks indoors.
• Shower within two hours of coming inside — it helps wash off unattached ticks and is a good moment for a tick check.
• Do a full-body tick check. Use a mirror and look under the arms, in and around the ears, inside the belly button, the back of the knees, in and around hair, between the legs, and around the waist. Check children the same way.

A simple tick-prevention gear checklist

You don't need much. These are the categories people commonly keep on hand for tick season. A product isn't a guarantee — follow the label and use them as part of the routine above.

• EPA-registered repellent (DEET, picaridin, IR3535, OLE, PMD, or 2-undecanone)
• 0.5% permethrin spray for gear, or pre-treated clothing and socks
• Light-colored long sleeves and pants for outdoor time
• A fine-tipped tweezers or a dedicated tick-removal tool
• A small sealable bag or container to hold a removed tick, if you want it identified
• A full-length or hand mirror for tick checks

If you find a tick: how to remove it

The CDC's guidance is straightforward: use clean, fine-tipped tweezers to grasp the tick as close to the skin's surface as possible, then pull upward with steady, even pressure. Don't twist or jerk (that can leave mouth-parts behind), and avoid "folk" methods like painting the tick with nail polish or using heat — the goal is to remove it promptly. After removal, clean the bite area and your hands, and dispose of a live tick by putting it in alcohol, a sealed bag, or flushing it. Note the date; if you develop a rash, fever, or other symptoms in the following weeks, tell your clinician about the bite.
