Remember the Four Ds:

DRAIN: Drain or treat all standing water in and around your home or workplace. Standing water can be found in swimming pools that are not kept clean, ponds, pet watering dishes, birdbaths, potted plants, old tires, empty containers, toys and clogged rain gutters.

DUSK/DAWN:  Limit outdoor activities during dusk and dawn when mosquitoes are most active.

DRESS: Wear long, loose, and light-colored clothing outside.

DEET All Day, Every Day:  Whenever you're outside, use insect repellents that contain DEET or other EPA approved repellents and follow instructions.

What the City is doing

  • Trapping and collections of mosquitoes weekly
  • Monitoring known breeding sites and applying larvicide.  Checking identified locations from citizen complaints; applying larvicide if needed
  • Enforcing City Codes and responding to standing water problems
  • Stocking Gambusia (minnows that eat mosquito larva) in standing water that cannot be emptied
  • Treating storm drains in areas identified by collections from surveillance
