Sheridan County Weed and Pest contracts aerial application of larvicide for mosquito control during the second full week of June, July, and August. The applications occur at daybreak, and the areas treated will be based on weather conditions and other factors. The major drainages, listed below, will be sprayed by a fixed wing aircraft targeting the standing water within 100 feet of each side of creeks and streams. Only mosquito breeding habitat will be treated.
The product being used is Vectobac 12 AS. It is a naturally occurring material which only affects mosquito and black fly larvae. This product will NOT affect, nor is harmful in any way to humans, honey bees, livestock, wildlife, fish or aquatic life. If you have questions or concerns, please call us at 307-672-3740.
We maintain a list of people that do not want sprayed, as well as a list of people we inform the week before spraying. If you would like to be added to a list, please call Luke.
