The most important thing that our residents can do to protect themselves from any mosquito-borne disease is to avoid mosquito bites. This can be accomplished by:

  • Using Insect Repellent with one of the active ingredients below. When used as directed, EPA-registered insect repellents are proven safe and effective, even for children.

    • DEET

    • Picaridin

    • IR3535

    • Oil of lemon eucalyptus (OLE) or para menthane-diol (PMD)

    • 2-undecanone

  • Wearing long-sleeved shirts and long pants when outdoors. Apply insect repellent to clothing to help prevent bites.  Treating clothes/uniforms with permethrin will also help repel mosquitos as well as ticks (see https://tickencounter.org/prevention/clothing_only_repellent_videos for how to’s)

  • Maintaining window and door screening to help keep mosquitoes outside.

  • Emptying water from mosquito breeding sites around the home, such as buckets, unused kiddie pools, old tires or similar sites where mosquitoes may lay eggs.

  • Using nets and/or fans over outdoor eating areas.
