What You Can Do

Fight the Bite

Fight off mosquitoes by using the 4 D's:

  • Limit outdoor activity during DUSK and DAWN when mosquitoes are most active.
  • DRESS in light-colored long sleeves and pants when outside to cover skin.
  • DRAIN standing water around your home. Mosquitoes typically breed in spots such as old tires, flower pots, rain gutters and bird baths.
  • DEFEND yourself by applying repellent before going outside. DEET (N, N-diethyl-m-toluamide) is an Environmental Protection Agency (EPA) approved ingredient to look for in your insect repellent that will help increase protection. Organic alternatives include orange spray, eucalyptus or citronella. Follow label instructions and always wear repellent when outdoors.

Take Action Around Your Home

The Department of State Health Services (DSHS) suggests taking the following steps around your home to help prevent mosquitoes from breeding:

  • Empty or rid of cans, buckets, old tires, pots, plant saucers and other containers that hold water weekly.
  • Keep gutters clear of debris and standing water.
  • Remove standing water from flat surfaces like flat roofs.
  • Change water in pet dishes daily.
  • Cover trash containers.
  • Change water in wading pools and birdbaths several times a week. Keep fountains running to keep water moving.
  • Water lawns and gardens carefully; prevent water from standing for several days.
  • Add Western Mosquitofish to ornamental ponds.
  • Dump out water that collects in outdoor toys.
  • Maintain swimming pools and keep them running up to 8 hours a day.
  • Repair leaks around your home and yard that may cause standing water.
  • Treat front and back door areas of homes with residual insecticides.
  • Screen rain barrels and openings to water tanks or cisterns.
  • Rinse and scrub vases and other indoor water containers weekly.
  • Apply pesticide to vegetation around the home if problems persist.
