Larvicide
The City of Watertown uses an organic larvicide which contains a naturally occurring, spore-forming bacterium found throughout the world in soil and aquatic environments, which is toxic to mosquito larvae upon ingestion but harmless to people and animals. The City plans to apply larvicide throughout the mosquito season. This will be applied not only to known breeding areas on public property, but to all storm sewer drains as well. Additional applications will occur as circumstances (wet weather) and surveillance dictates.
