What are the "Four Ds?"
1. Dress in long sleeves and pants whenever you are outdoors, when possible. Helpful Tip: Spray clothing with repellent since mosquitoes may bite through thin clothing.

2. Dusk/Dawn are the times of day when you should try to avoid outdoor activity because these times are when mosquitoes are most active/feeding.

3. Use insect repellents that contain DEET, picaridine, oil of lemon eucalyptus, or IR3535. Spray skin and clothing with repellent. Be sure to read label instructions on any repellent.

4. Drain all standing water around your home, apartment, and or business since these are mosquito breeding sites.
  • Change the water in birdbaths and wading pools at least once a week.

  • Do not allow water to accumulate in the saucers of flowerpots or in pet dishes for more than 2 days.

  • Get rid of tin cans, old tires, buckets, unused plastic swimming pools or other containers that collect/hold water.

  • Clean debris from rain gutters and repair leaks around faucets and air conditioners.

  • Check for trapped water in plastic or canvas tarps used to cover boats or pools. Arrange the tarp to drain the water.

  • Fill or drain puddles and ditches.
