Mosquito larvae can develop in water that has been standing for more than four days.

Eliminate stagnant water where mosquitoes lay their eggs.

Keep your yard clean

  • Remove discarded tire and clean up junk piles that collect water
  • Cover containers or use lids to prevent water from collecting in the bottom of garbage cans
  • Use screen or fine mesh to cover rain barrel
  • Clean pet food and water bowls and store indoors when not in use

Clean out eaves, gutters and drains

  • Clear leaves, twigs and debris from eavestroughs, storm and roof gutters throughout the summer
  • Make sure drainage ditch is not clogged
  • Check flat roofs frequently for standing water

Maintain yards and lawns

  • Fill in low depressions in lawn areas
  • Eliminate standing water in gutters or storm drains to prevent small ponds
  • Install screens over catch basins
  • Grass clippings, leaves or other decaying debris, such as apples or berries that fall from trees should be mulched to prevent organic matter from going into catch basins or storm sewers as food source for mosquito larvae
  • Turn over compost frequently

Always inspect swimming or wading pools and ponds

  • Remove water that collects on pool covers
  • Make sure the pool's pump is circulating water
  • Turn over wading pools when not in use

Eliminate stagnant water

  • Clean up and empty water in toys, birdbaths, tires, flowerpots, wheelbarrows and other garden objects
