Rockland Health Department have begun treating catch basins and storm drains to prevent mosquitoes from breeding in standing water inside of these structures. This work will be performed throughout the County and is planned to be completed by the end of the month.

Mosquitoes lay their eggs in or near stagnant (still) water, and their offspring (called larva) “grow up” in water before emerging as adult mosquitoes that fly and bite. Since the West Nile virus outbreak in 1999, the Health Department has been collecting, identifying and tracking mosquitoes, both in their adult and larval stages, and providing education and free mosquito control products to the public to reduce the mosquito population.

The Mosquito Control Program focuses on reducing Rockland’s mosquito population at the larval stage during the spring and summer months through the identification and monitoring of over 1,000 mosquito-breeding sites. In addition, approximately 50,000 road-side catch basins throughout the County are reviewed and treated, as needed. Program staff also conduct routine and complaint-based inspections at many commercial properties that are considered “high risk” for mosquito breeding, including tire-storage facilities, landscape yards, municipal storage yards, outdoor swimming pool facilities, horse farms, marinas, and garden centers, as well as respond to complaints against private residential properties.

“Mosquitoes can sometimes spread disease, such as West Nile Virus or Zika Virus. The West Nile Virus has been found in local mosquitoes, and Rockland County has had cases of the virus in people which was spread from local mosquitoes. The Zika virus has not been found in local mosquitoes, and our only cases of Zika are from people who have traveled to areas where the Zika Virus is spreading,” said Dr. Ruppert.
