Mosquito Control

The Village of Oswego contracts with Clarke to provide mosquito control services in the Village.  Clarke uses a comprehensive program providing surveillance of the mosquito population, larval control, and adult mosquito control to help minimize mosquito populations to prevent nuisance mosquitoes and help suppress any outbreaks of West Nile Virus. This program closely follows the recommendations of the U.S. Centers for Disease Control and Prevention guidelines and uses products registered with the U.S. Environmental Protection Agency. 

You can help

The most environmentally friendly method of controlling mosquitoes is simply to eliminate their breeding grounds. Residents should tip and toss any standing water in birdbaths, baby pools or downspout drains every 2-3 days to prevent mosquito larvae from developing. Even a bottle cap can contain enough water for a mosquito to lay eggs. Mosquito eggs can also survive winter freeze-and-thaw cycles. Residents should be vigilant about removing standing water all year long. 

When going outdoors, long shirts, long pants, and DEET-based mosquito repellent are recommended.  Also try to avoid going out at dawn and dusk, when mosquitoes are most active.

Get spray notifications 

Clarke offers a notification system alerting residents when spraying will be conducted.

To receive a text or email notification when spraying is scheduled in Oswego, visit, enter your contact information, and click 'Register for Notifications.'

To be placed on the automated call list, call Clarke’s Mosquito Hotline at 800-942-2555.

Spraying is usually conducted across the entire village, and the process begins at dusk, when mosquitoes are most active, and continues for several hours. Because of this, notifications will alert residents which days the Village is being treated, but cannot offer specific street-by-street data.
