The Bedford Department of Public Works will start its annual program to treat catch basins to prevent West Nile Virus, a disease carried by the Culex (Q-lex) mosquito, beginning the week of July 5th. This mosquito mostly breeds in storm drains, but can also survive in any open container holding even a half-inch of water.

According to the Center for Disease Control, it is important to target the larvae stage of the mosquito, since once the adult has hatched, it can transmit the virus to humans and animals. Small packets that contain a selective insecticide for the Culex larvae will be dropped by licensed DPW employees into catch basins in target neighborhoods. These areas include senior populations, horse barns, densely populated, and public lands. The active chemical, Methoprene, prevents mosquitos from reproducing. The chemical is not harmful to humans, fish, pets, plants, or birds.

For additional information, please contact the Bedford DPW or the Bedford Health Dept. The Eastern Middlesex Mosquito Control District is overseeing this annual project and can be reached at (781) 899-5730.
