PUBLIC NOTICE: Unscheduled Mosquito Control Activity in Prince George’s County

Spraying Planned for Evenings of August 24 and 25, 2025

ANNAPOLIS, MD (August 23, 2025) – The Maryland Department of Agriculture, in cooperation with the Prince George’s County Health Department, will expand mosquito control services in areas due to a public health concern over the potential for mosquito-borne diseases.

Ultra-Low Volume (ULV) truck-based spraying to control adult mosquitoes is planned for the following evenings in the following areas:

• Sunday, August 24, 2025– City of College Park within a ¾ mile radius of Old Calvert Road and Calvert Park and Drexel Road (to include Riverdale Park and University Park)
• Monday, August 25, 2025- City of Greenbelt within a ¾ mile radius of Northway Ballfields

Spraying will occur after 7:30 p.m. In the event of inclement weather, spraying will be rescheduled for the next available evening. Any existing spray exemptions in the area will be temporarily suspended.

MDA Mosquito Control Program personnel will use a permethrin-based solution that the U.S. Environmental Protection Agency has approved for use in public health mosquito control programs without posing unreasonable risks to human health. However, out of an abundance of caution, MDA recommends avoiding outdoor activities during spraying.

While not all mosquitoes carry diseases, MDA suggests that residents take precautions to minimize their exposure to mosquito bites. These measures include:

• Wear long, loose fitting, light colored clothing
• Wear insect repellents according to product labels
• Avoid mosquito infested areas during prime periods of activity (between dusk and dawn)
• Install, inspect, and repair window and door screens in homes and stables
• Regularly clean bird baths and bowls for pet food and water
• Remove or empty all water-holding containers

All Marylanders are encouraged to follow MDA’s Facebook feed @MdAgDept that will post unscheduled spray events and other timely information about mosquito control in Maryland. Routine spray program schedules are available by county on the program’s website.
