Many of the more common mosquito species will readily reproduce around or near homes, and these mosquitoes may not stray far from their breeding sites. So prevention begins at home. Mosquito larvae, or "wigglers," require some form of moisture to survive. Even temporary standing water will serve the purpose. Mosquito breeding sites will be revealed by a slow, close inspection around homes. Stagnate pools of water in ditches is an obvious mosquito generator as are outdoor toys and potted plant trays that collect and hold water.
