When will the Town be spraying for mosquitoes?
Surveillance and Control of Immature Mosquitoes is
done March to October.
Surveillance and Control of Adult Mosquitoes is done June to September.
For the 2023 Season, routine spraying is done weekly on Tuesdays from 6:00 pm to 9:00 p.m. Spraying will be done only if a Maryland Department of Agriculture Inspector determines it is necessary. Please monitor for any Unscheduled Mosquito Control public notices on Twitter@MDAgDept.
Criteria for Spraying: Nuisance Mosquito Control
Landing Count: 3 mosquitoes landing in 2 minutes.
Light Trap Collection: Capture of at least 12 female mosquitoes of a species known to fee on humans, per night in an unbaited trap.
The Mosquito Control Program does not spray for Midges that cover homes and boats along many St. Mary’s rives in April and May. These non-biting insects that develop in mud bottoms of slow moving creeks and rivers show a decline in populations a few weeks after emergence.
