Throughout the duration of the spraying, the Health Department will use very low concentrations of Anvil® 10+10, Duet®. The risks of pesticides are low to people and pets, but some people who are sensitive to spray ingredients may experience short-term eye or throat irritation, or a rash. People with respiratory conditions may also be affected.

The Health Department encourages New York City residents to mosquito-proof their homes and take precautions when spending time outdoors, and reminds them that the best way to control mosquitoes is to eliminate any standing water. Use an approved insect repellent containing DEET, picaridin, oil of lemon eucalyptus (not for children under three), or products that contain the active ingredient IR3535.

New Yorkers are encouraged to eliminate any standing water from homes and make sure gutters are clean and draining properly. Clean and chlorinate swimming pools, outdoor saunas and hot tubs and should be empty or covered if not in use, and drain water that collects in pool covers. Make sure windows in homes have screens, and replace any damaged or ripped screens.
