The Suffolk County Department of Public Works will spray sections of Manorville and Calverton by helicopter Monday night to control the breeding of adult mosquitoes.

The spraying is in response to the confirmation of additional mosquito samples that have tested positive for Eastern Equine Encephalitis virus. See separate story.

Weather permitting, Suffolk County vector control will spray Anvil (sumithrin) from River Road/Grumman Boulevard to South River Road and the L.I. Rail Road tracks extending from Princeton Avenue to Railroad Avenue on Monday, Aug. 19, from 7 p.m. to 12 midnight. If inclement weather cancels the spraying, it will be rescheduled for Tuesday, Aug. 20.

Suffolk health officials say residents “chances of experiencing any health effects from spraying are quite low,” but say they should take “common sense steps” to help reduce possible exposure to pesticides before, during or after spraying.

According to the health department, children and pregnant women should take care to avoid exposure when practical. If possible, they should remain inside or avoid the area whenever spraying takes place and for about 30 minutes after spraying.

Residents should close windows and doors and close the vents of window air-conditioning units to circulate indoor air or, before spraying begins, turn them off. Windows and air-conditioning vents can be reopened about 30 minutes after spraying.

If you come in direct contact with pesticide spray, protect your eyes. If you get pesticide spray in your eyes, immediately rinse them with water. Wash exposed skin. Wash clothes that come in direct contact with spray separately from other laundry.

Consult your health care provider if you think you are experiencing health effects from spraying.

The materials used by vector control do not leave significant residues on surfaces, the health department said, but exposure can be reduced even further. Pick homegrown fruits and vegetables you expect to eat soon before spraying takes place. Rinse homegrown fruits and vegetables thoroughly with water before cooking or eating. Bring laundry and small toys inside before spraying begins. (Wash with detergent and water if exposed to pesticides during spraying.) Bring pet food and water dishes inside, and cover ornamental fishponds during the spray period to avoid direct exposure.

Questions about Eastern Equine Encephalitis virus should be directed to the Suffolk County Department of Health Services’ Public Health Hotline: 631-787-2200.
