Prevention:

Eliminate or reduce mosquito breeding sites by replacing all standing water at least once a week. This includes bird baths, ponds and unfiltered pools. Remove unneeded vegetation or trash from around any standing water sources that cannot be changed, dumped or removed. Introduce mosquito-eating fish such as gambusia, green sunfish, bluegills and minnows to standing water. Screen windows, doors and other openings with mesh. Avoid going outdoors when and where mosquitoes are most active: during dusk or dawn. Use insect repellent containing DEET on exposed skin whenever or wherever mosquitoes are likely to bite.
