Tick Bite Prevention During Pregnancy: 12 Essential Tips

Why Extra Caution?

Pregnancy alters immune response; some tick-borne illnesses (Lyme, babesiosis, anaplasmosis) may have worse maternal/fetal outcomes. Doxycycline (first-line for Lyme) is contraindicated in pregnancy.

Personal Protection

  1. Clothing: Light-colored, long sleeves/pants tucked into socks; closed shoes.
  2. EPA-registered repellents: DEET 20–30%, picaridin 20%, IR3535, or oil of lemon eucalyptus (OLE) — all safe in pregnancy per CDC/EPA.
  3. Permethrin-treated gear: Treat clothing/boots (0.5%); not for direct skin use.
  4. Hair & hat: Tuck hair; wear hat in woods.

Environmental Avoidance

  • Stay on cleared trails; avoid tall grass, leaf litter, brush.
  • Keep yard mowed; remove leaf litter; create 3-ft woodchip barrier between lawn and woods.
  • Peak tick activity: dawn/dusk, April–September (varies regionally).

Post-Exposure Routine

  1. Full-body tick check (mirror, partner) within 2 hours of coming indoors.
  2. Shower promptly; wash/dry clothes on high heat 10 minutes.
  3. Check pets, gear, strollers.

If You Find an Attached Tick

  1. Fine-tipped tweezers: grasp close to skin, pull upward steadily.
  2. Clean bite site (alcohol/soap).
  3. Save tick in alcohol for identification/testing if desired.
  4. Monitor for rash (EM), fever, flu-like symptoms × 30 days.
  5. Contact OB/GYN — discuss prophylactic antibiotic options (amoxicillin/cefuroxime) per current guidelines.

Prevention is paramount; early removal (<36 hours) virtually eliminates Lyme transmission.
