Prevention

Fight the Bite Arizona!

The best way to protect you and your family from WNV, or any other mosquito-borne illness, is to reduce the number of mosquitoes around your home and neighborhood and to take personal precautions to avoid mosquito bites. These are some of the preventative steps that you can easily take:

  • Eliminate standing water where mosquitoes can breed. Check for items outside the home that collect rain or sprinkler water, such as cans, bottles, jars, buckets, old tires, drums, wheelbarrows, boats, kid pools, and other containers.
  • Change water in flower vases, birdbaths, planters and animal watering pans at least twice a week.
  • Repair leaky pipes and outside faucets, and move air conditioner drain hoses frequently.
  • Avoid being bitten by mosquitoes when going outside at night by using insect repellent. Wear lightweight clothing that covers the arms and legs.
  • Report mosquito breeding problems (e.g. green pools) to your local environmental health office.
