If you live in or travel to an area with Zika, protect yourself from mosquito bites.
Make sure to: 

  • Get rid of standing water in your yard. Mosquitoes lay
    eggs near water. Check pots and planters, outdoor kids’ toys, bird baths, and any
    other containers for puddles of water. Empty the water regularly and keep these
    areas clean and dry.

  • Choose air conditioning or screens. At home, don’t
    leave windows or doors open unless they have screens. Patch any holes in the
    screens. When picking a restaurant, hotel, or other venue, choose places with
    screens in windows and doors, or air conditioning.

  • Wear protective clothing. Wear clothing that covers
    your body to prevent mosquito bites. Choose clothing with long sleeves and long
    pant legs. Wear socks and shoes to cover your feet and ankles.

  • Use insect skin spray often. Buy a skin spray that is
    EPA-approved and contains DEET, picaridin (also called KBR 3023, Bayrepel, or
    icaridin), oil of lemon eucalyptus (OLE), para-menthan-diol (PMD), or IR3535. Make
    sure to follow the instructions on the label about how to apply and when to
    reapply. Use it during the day and at night. EPA-approved insect sprays are safe
    for pregnant and breastfeeding women.

  • Use permethrin. This is a type of insecticide you can
    apply to fabrics. If you are going camping, treat your clothing, shoes, and your
    tent with permethrin. You can also buy gear that’s already treated. Don’t use
    permethrin directly on your skin.

  • Sleep with a mosquito net. Make sure to use a mosquito
    net if you are sleeping outdoors or in a place with no screens or air
