Prevent Bug Bites

What to know before you go. Bugs can spread diseases.

Travelers to tropical and other destinations should take steps to prevent bug bites.

  • Protect yourself.
    • Wearing insect repellent with at least 20% DEET protects against mosquito and tick bites.
    • Use insect repellents according to package directions, and reapply as directed. Higher percentages of the active ingredient provide longer duration of protection.

  • Other ways to prevent bug bites:
    • Wear long sleeves and pants.
    • Use permethrin-treated gear and clothing.
    • Sleep in places that are air conditioned or screened against bugs.
    • Sleep under a bed net if sleeping area is exposed to the outdoors.

    • Mosquitoes: dengue, chikungunya, malaria, Zika, yellow fever, Japanese encephalitis
    • Ticks: African tick-bite fever, Mediterranean spotted fever, tickborne encephalitis
    • Other: scrub typhus (chiggers), plague (fleas), sleeping sickness (tsetse flies)
  • See a doctor if you get sick after traveling and tell the doctor you traveled.
