ANNAPOLIS, MD (August 31, 2026) – The Maryland Department of Agriculture (MDA) will treat a targeted area of Dorchester County to reduce the adult mosquito population in the region. Treatment is scheduled to occur via aerial spraying the evening of Monday, August 31, 2026. In the case of inclement weather, spraying will take place the following evening of Tuesday, September 1, 2026.
The following areas of Dorchester County will be treated: Andrews, Bishops Head, Black Water, Crapo, Crocheron, Lakesville, Robbins, Toddville, Wesley and Wingate. Approximately 13,626 acres will be sprayed.
A twin engine, white plane with red and blue stripes, will apply Trumpet throughout the targeted region, from a height of approximately 300-500 feet above the ground. The aircraft’s registration number is N903MD. Trumpet is a formula containing naled and will be applied at less than 1.0 fluid ounce per acre. Naled is one of the most commonly-used insecticides in the United States for mosquito control and it is not necessary for people, pets or livestock to leave the area during the spraying.
This notice satisfies Federal Aviation Administration requirements of notifying the public before aerial spraying occurs over communities.
