Oswego (WSYR-TV) – Health officials in Oswego County announced that aerial spraying will take place Thursday night if weather permits.
The Oswego County Health Department said on Wednesday that more evidence of Eastern Equine Encephalitis and West Nile viruses were discovered in pools collected last week.
Health officials say a pool in the town of West Monroe and another near the village of Central Square both tested positive for EEE.
Two pools near the village of Central Square and another in the town of West Monroe each tested positive for WNV.
The area to be sprayed is the Toad Harbor / Big Bay Swamp area near the north shore of Oneida Lake. Specifically, the area includes about 10,000 acres within these boundaries: U.S. Route 11 in Central Square to the west, NYS Route 49 to the north, up to, but not including the village of Constantia to the east; and the shoreline of Oneida Lake to the south. Spraying will not take place over the waters of Oneida Lake.
Residents within the aerial spray boundaries will be notified of the aerial spraying by the Oswego County Hyper-Reach reverse 911 program. They are also advised to close windows and doors and keep them closed until 9 p.m.
If the spraying is postponed, the county health department says residents will be notified through NewsChannel 9 and other local media or through the county's website
On Wednesday, the county announced that two new pools of mosquitoes infected with West Nile virus had been collected in the town of West Monroe.
The pools were collected on Sept. 6, before they began spraying.
The county uses the product Kontrol 30-30, which contains permethrin.
It says the spray will be applied in a diluted form.
The county has contracted with Duflo Spray-Chemical from Lowville to conduct the aerial spraying.
Health officials are advising people to:
- Use insect repellent properly. Those that contain DEET, picaridin or oil of lemon eucalyptus are most effective but should be used with care. Read the product label and use according to package instructions.
- Limit outdoor activities in areas where mosquitoes are most active and between dusk and dawn, which is the peak mosquito biting time.
- If you have to be outside, wear long-sleeved shirts, long pants, shoes and socks as weather permits.
In addition, residents can take these protective measures to minimize mosquito populations in and around their homes and properties:
- Repair or replace all window and door screens to keep mosquitoes outside.
- Reduce or eliminate all standing water.
- Empty or dispose of pails, cans, flower pots, or similar water-holding containers.
- Clear roof gutters, remove leaf debris from yards and gardens, and clean vegetation and debris from the edge of ponds.
- Turn over wheelbarrows and wading pools when not in use.
- Clean and chlorinate swimming pools, outdoor saunas, hot tubs and drain pool covers.
- Change the water in birdbaths and horse troughs twice a week.
- Dispose of old tires at an Oswego County transfer station. There is a minimum $10 disposal fee. Contact the Oswego County Solid Waste Department at 591-9200 for details.
