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 free mosquito control products:

Mosquito Dunks® contain bacteria that kill mosquitoes in their larval stage in water, before they become flying, biting adults. They are for homeowner swimming pool use ONLY. Dunks should be placed in swimming pool covers or in open swimming pools that are not being disinfected and filtered. 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 Mosquito Dunks®. They are available until October 31st, while supplies last. It is important to know the size of your pool when coming to pick up your dunks.

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 minnows should be released in areas that have at least 8 inches to 12 inches of water, such as an ornamental pond. You do not need to stock streams and rivers with these minnows, since mosquitoes generally do not lay eggs in moving water. Also, if fish are already in the water, then fathead minnows are not needed, as other fish should provide control.

  • To order the minnows, while supplies last, call (845) 364-3173 or visit . Please order by April 15th.
  • The fish are available for pick-up ONLY on Wednesday, April 20th from 4:30 p.m. – 7:30 p.m. 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 all the correct 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.

"Mosquitoes are more than a annoying pest; they can carry several diseases, including West Nile Virus and dog heartworm. There is a small risk that the Asian Tiger Mosquito (Aedes albopictus), which we have in Rockland, may be able to carry and spread the Zika Virus," 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.
