Countywide : Mosquito Season and Its Dangers Arrive

Those late April showers may be bringing a sharp increase in mosquitoes throughout Orange County, and expected rains this week could make things even worse, Vector Control District officials are warning.

Large amounts of standing water have been left by the rains, creating a perfect breeding ground for mosquitoes.

With high numbers of mosquitoes come increased potential for disease. The western encephalitis mosquito, carrier of a serious infection by the same name, is one of 21 species of mosquitoes found in Orange County. All require standing water for development.

Officials say residents can help by inspecting their yards for containers, such as garbage cans and barbecues, that may have collected water. And as summer approaches, officials urge careful lawn and garden irrigation.

Mosquito-eating fish also are available for free from the district for use in ornamental ponds and other permanent water sources.

“One female fish will consume about seven times her weight in mosquito larvae,” said B. Fred Beams, assistant manager of the Vector Control District. At this time of the year, when mosquito eggs hatch more quickly than in winter, officials depend on the public to help eliminate them on private property, Beams said.

The district conducts mosquito surveillance and control on public areas in the county, such as flood control channels, catch basins and marshes.
