Change water in birdbaths, fountains and troughs weekly. Make sure septic and other water tanks are sealed with screened vents. Empty wading pools when not is use and keep swimming pools clean and filtered. Make sure boats are covered or water drains out of them completely. Store small boats upside down.
Flush sump pumps weekly.
Do not dump leaves or grass clipping into a catch basin. Maintain screening to exclude mosquitoes from house or business. However, outdoor areas are more difficult to treat with an aerosol and therefore foliage sprays applied to shrubs and grassy areas are usually better for use in the yard. Remember, chemical control of mosquitoes is a short-term remedy and is usually more expensive and less effective then eliminating the breeding source. Mosquitoes may be prevented from coming indoors by properly screening windows and doors.
