What you can do

  • Stay in air-conditioned or well-screened places.
  • Repair broken screens on windows and doors so mosquitoes can’t get inside your house.
  • Wear insect repellent when outdoors.
    • Make sure the repellent contains an EPA-registered product
      • DEET (20% DEET or higher also prevents tick bites)
      • Picaridin
      • Oil of lemon eucalyptus
      • IR3535
  • Follow instructions since repellent needs to be reapplied for ongoing protection.
    • Apply sunscreen before repellent.
    • An adult should apply repellent to children. DEET can be used on children 2 months and older.  Oil of lemon eucalyptus should only be used on children 3 years of age and older.
  • Wear long pants and long sleeves when weather permits.
  • Treat clothing with permethrin (travelers, outdoor workers or others who spend a lot of time outside).
  • Once or twice a week check and empty sources of standing water outside your home where you work and play. Mosquitoes can breed and grow in very small containers that fill with rain water, such as bottle caps and cups. See our checklist for reducing standing water.

Control mosquitoes at home

Mosquitoes lay their eggs in standing water. You can help prevent mosquito populations from growing by draining or covering sources of standing water around your home.
