State health and agriculture officials in Maryland are moving forward with an unscheduled mosquito control operation in Prince George’s County, scheduled for the evening of July 19, 2026.
The Maryland Department of Agriculture, working alongside the Prince George’s County Health Department, announced the expanded spraying effort in response to growing concerns about the potential for mosquito-borne illnesses in the area.
Officials plan to use Ultra-Low Volume, or ULV, truck-mounted spraying equipment to target adult mosquito populations across affected neighborhoods. This type of spraying involves applying very small amounts of pesticide to reduce mosquito activity in the area.
The decision to conduct the unscheduled treatment reflects the agencies’ efforts to get ahead of any potential public health threat tied to disease-carrying mosquitoes.
