Mosquito Control


  • At least once a week, drain water from garbage cans, buckets, toys, flowerpots, wading pools, pet dishes and other objects that collect water.
  • Change water in birdbaths at least once a week.
  • Keep gutters cleaned out, and repair any tears in door and window screens.
  • Wear long-sleeved shirts, long pants and light colors outdoors.
  • Spray clothing with repellents containing DEET or picaridin, making sure to follow the directions on the label.
  • Look for products containing the active ingredient methoprene or Bti (Bacillus thuringiensis israelensis) to place in birdbaths or ponds, to prevent mosquitoes from developing.
