Bad news for foreclosures with pools. Nature will win.
Nature has dibs on swimming pools, especially abandoned ones. Pools left alone with no upkeep become a nesting spot for mosquitoes to breed and further increase the public concern with the mosquito-borne West Nile virus.
Local mosquito control agencies in Arizona, Florida and California are dumping the Gambusia affinis into vacant pools, where fish, also known as “mosquito fish” gorge themselves on mosquito larvae. Many environmentalists applaud the effort to control the mosquitoes with no pesticides, the fish do carry an environmental cost IF they find their way into local water systems. How come? The mosquito fish tend to push around native wildlife, including tadpoles of endangered frogs.
