  • We do not know the effectiveness of non-EPA registered insect repellents, including some natural repellents.
  • To protect yourself against diseases spread by mosquitoes, CDC and EPA recommend using an EPA-registered insect repellent.

Wear long-sleeved shirts and long pants

  • Treat items, such as boots, pants, socks, and tents, with permethrin or buy permethrin-treated clothing and gear.
    • Permethrin-treated clothing will protect you after multiple washings. See product information to find out how long the protection will last.
    • If treating items yourself, follow the product instructions.
    • Do not use permethrin products directly on skin.
