NEW CITY, NY - - To help County residents reduce the number of mosquitoes on their property, Rockland County Executive Ed Day and County Health Commissioner Dr. Patricia Schnabel Ruppert announce the availability of these free mosquito control products:

Mosquito Dunks®
Come to the Health Department, Building D, 50 Sanatorium Road in Pomona, Mondays - Fridays, from 9:00 a.m. to 4:00 p.m. for your free one month's supply of Mosquito Dunks®. They are available until October 31st, while supplies last. Dunks are small, donut-shaped objects that float on the water's surface and release bacteria that kill mosquitoes in their larval stage in water, before they become flying, biting adults. They are for use in closed or unused private swimming pools and spas, and are effective for approximately 30 days. A single dunk will treat an area of about 100 square feet. ALWAYS FOLLOW THE LABEL INSTRUCTIONS when using Mosquito Dunks® or any other pesticide. It is important to know the approximate dimensions of your pool/spa to ensure that you get the proper number of dunks for effective treatment. In addition, residents can request free larvicide tablets by calling the New York State Department of Health at 1-888-364-4723.

Fathead Minnows
Fathead minnows will be available for one day only and they must be ordered in advance. The fish are available for pick-up ONLY on Thursday, April 20th from 4:30 PM - 6:30 PM at the Health Department, 50 Sanatorium Road in Pomona. Follow the "Free Dunk/Fish" signs from Sanatorium Road to the giveaway location. Please call (845) 364-3173 on April 20th between 9 a.m. - 4 p.m. to make sure that the fish giveaway will take place as scheduled. The Health Department will provide the required permits to allow you to stock the fish within Rockland County. The fish will be in a sealed bag for transport. Please bring a bucket or small cooler. To order the minnows, while supplies last, call (845) 364-3173 or visit Please order by April 15th.

Fathead minnows are a type of fish that eat mosquito larvae before they become flying, biting adults. They can eat up to 200 mosquito larvae per day. The fish can be placed in unused swimming pools, ornamental ponds, and other similar areas that have a minimum of eight inches of water. It is not necessary to stock streams and rivers with these fish, as mosquitoes generally do not lay eggs in moving water. If fish are already present, it is not necessary to add Fathead minnows, as the existing fish population should provide appropriate mosquito control.

"Mosquitoes are usually just thought of as an annoying pest, however they can sometimes spread disease, such as West Nile Virus or Zika Virus. While Rockland has cases of West Nile Virus spread from local mosquitoes, the only cases of Zika to date in Rockland are from people who have traveled to areas where the Zika Virus is spreading," said Dr. Ruppert.

In addition to the mosquito control products above, to help keep your property mosquito-free: be sure to check around your property for any items that can hold water and get rid of the items or empty the water out and scrub the objects at least once a week.
