West Nile has been found in many parts of the world, including Europe, Asia, Africa, and now the U.S., even California. Most people and animals who become infected with the virus have only a mild illness and no symptoms. However, in rare cases, people can become seriously ill or die. In 2003, there were 240 deaths attributed to West Nile virus in 45 states. That said, it should be reiterated that most people infected with the virus will have no symptoms and not even feel ill. About one in five may get a fever, headache or body ache. At the same time, why take the chance and simply eliminate possible mosquito breeding grounds around your garden? For instance, mosquitoes can breed in as little as a tablespoon of water. Eliminate all sources of standing water on your property that can support mosquitoes.
Prime breeding areas around your home are bird baths, garden ponds, extra garden containers and saucers that may be laying around, even that used tire that you saved for no apparent reason. I know that I had several old saucers collecting water in the junk pile on the side of the house that my wife is always harping on me to clean up. Rain gutters clogged with leaves are yet another common source around homes.
So-called mosquito dunks for ponds and birdbaths can be found in many hardware and garden supply stores. You can also simply change the water in birdbaths weekly to make sure the standing water won't become a breeding ground for mosquitoes. Many counties also give away free mosquito fish (minnow-like fish that eat mosquito larvae). For information, call the Santa Clara County Vector Control District at (800) 675-1155.
