For homes in the area that have been identified as having a suspect swimming pool, District staff makes a visit to help pool owners eliminate their mosquito problem. For residents that have not been availble during daytime hours, contact will be attempted during the evening. Staff are dressed in uniform, wear photo identification badges and drive Ford F-150 full size pickups marked with the District emblem and have CA exempt license plates. Pools regularly treated with chlorine will be mosquito free. Once these pools are visually inspected, no further contact will be nescessary. Swimming pools that are producing mosquitoes can quickly and easily be treated. The treatment will last all season. At any time later the pool can be made ready for swimming.
