The Mosquito Control Program
This program operates within the Environmental Health Division of the Rockland County Department of Health (RCDOH). It is a comprehensive program that employs larval mosquito control and surveillance practices, as well as adult mosquito surveillance practices. The program additionally provides general mosquito education to the public in an effort to reduce the mosquito population in Rockland County. This program also enforces Article XIX of the Rockland County Sanitary Code while working in conjunction with other enforcement entities within the Department of Health. We have been proudly serving Rockland County in this fashion since the West Nile virus outbreak of 1999.
FREE Mosquito Dunks
Mosquito Dunks® can be picked up from the Health Department in Pomona, Bldg D for homeowner swimming pool use ONLY. They are available from April 1st - October 31st, Monday - Friday 9:00am-4:00pm, while supplies last.
Larval Mosquito Control
This aspect of the program focuses on reducing Rockland's mosquito population at the larval stage. Larval control is performed during the spring and summer months through the identification, monitoring and treatment of over 1,000 mosquito-breeding sites and approximately 50,000 road-side catch basins throughout the County. In an attempt to minimize pesticide use, biological mosquito control is employed in the form of free give-aways to the public. Mosquito Dunks
are available (while supplies last) to assist private homeowners with unused or unmaintained swimming pools to eliminate mosquito breeding and to obtain compliance. Additionally, the Department holds a one day give-away of Fathead Minnows (mosquito-eating fish). This event provides a fun way for residents to perform their own mosquito control in the waters of Rockland County.
Treatment Products Routinely Used by RCDOH Mosquito Control Staff:
This program conducts routine and complaint-based inspections at many commercial properties that are considered "high risk" for mosquito breeding potential. Properties include tire-storage facilities, landscaper yards, municipal storage yards, outdoor swimming pool facilities, horse farms, marinas, garden centers, etc. Inspectors also respond to complaints against private residential properties. A letter is sent to the owner/occupant of the property of concern to inform about mosquito breeding, educate on the importance of eliminating breeding sources and how to accomplish it as well as a reminder of the Sanitary Code requirements. While conducting an inspection, field staff are authorized to access a private property to look for potential mosquito breeding habitats and/or evidence of mosquito breeding. If mosquito breeding is found, a sample is collected for identification. Whenever education and assistance fails and/or violations are not corrected in a timely manner, Health Department staff may take action to eliminate the mosquito breeding hazard. This Department then has the authority to take legal action, which could lead to an Administrative Hearing and/or financial penalties.
This aspect of the program focuses on the collection, identification and tracking of mosquito species, both in their adult and larval stages. Mosquito trap sites are located throughout the County and are monitored from June through September. Adult mosquitoes are collected and grouped ("pooled") by location and species. Specimens are submitted weekly to NY State labs to be tested for mosquito-borne diseases such as West Nile virus (WNV). WNV testing results can be viewed here. Larval mosquito specimens are sampled from open breeding sites by field staff and are identified by species. Nearly 2,000 samples are identified each season. Enhanced surveillance will be employed during the 2016 season to more closely monitor the Asian Tiger Mosquito (Ae. albopictus) due to its possible link to Zika Virus.
Storm Water Plan Reviews (Mosquito Breeding Suppression Plans) & "Fee For Service"
The Rockland County Health Department requires that Mosquito Breeding Suppression Plans (MBSPs) be submitted to and approved by this office at least 30 days prior to construction of a new storm water facility. A storm water facility includes but is not limited to: Detention Basins, Retention Basins, Recharge Basins, Catch Basins, Dry Wells, Level Spreaders and Underground Chambers. The MBSP shall describe actions to be implemented to reduce mosquito breeding potential at all new storm water facilities. Effective actions may include, but are not limited to design standards that prevent breeding, chemical or biological treatment or the installation of an aeration system. Additional information can be found in our Forms and Permits page under Mosquito Control and in Article XIX of the Rockland County Sanitary Code. For additional information, please call 845-364-3173.
