MDA set to provide residential mosquito control
CENTREVILLE — Mosquito Control service is provided to the residents of Queen Anne’s County through the Maryland Department of Agriculture from May through September. Applications for individuals not belonging to one of the listed communities are still being accepted at the MDA office located at the Queen Anne’s County Department of Public Works.
The Mosquito Control Program is a service provided by the Maryland Department of Agriculture’s Mosquito Control Section in cooperation with the Queen Anne’s County Department of Public Works. Mosquito surveillance and control operations will be exclusively conducted by MDA personnel. Funding for mosquito control is provided by state and county tax dollars and user fees.
According to MDA, mosquitoes in Queen Anne’s County affect the public health and quality of life of both the residents and visitors to the county. Queen Anne’s County contains a variety of mosquito habitats including marshes and flood plains. Mosquito production along the coast can have a negative impact on tourism, and mosquito production inland can impact public health through the transmission of diseases. The tiger mosquito, a predictable nuisance, is commonly found in Mar yland and tends to be most active in the late afternoon.
Daniel Schamberger, environmental scientist at MDA, said the formula used is the safest and most effective with the lowest warning label of any product available on the market for this type of application. The active ingredient, Permethrin, is approved by the Centers for Disease Control for application on human clothing and is the recommended ingredient for personal mosquito control. The agency also targets mosquito larvae with an organic larvicide.
Schamberger said they will typically spray after sunset, but can spray anytime before sunrise. The spray, he said, dissipates from the air in 20 to 30 minutes and has no residual effect. It is recommended that residents refrain from outdoor activities while spraying is being done in the immediate area. If contact is made with skin, rinsing off the affected area with water is recommended. Schamberger also suggests replacing pets outdoor water supply with fresh water after spraying is completed.
MDA conducts regular surveillance and control of adult mosquitoes. On average Schamberger said biweekly service will occur anytime between 7 p.m. and 4:30 a.m. Spraying for adult mosquitoes will be done only if a Maryland Department of Agriculture Inspector determines it is necessary. Thresholds for Ground Based ULV Treatments include: Landing Counts: 3 mosquitoes in a 2 minute count; Light Trap Collections: 12 female mosquitoes in an un-baited light trap or 24 female mosquitoes in a baited light trap; and conditions that threaten public health, such as mosquito borne disease.
Spraying will not be conducted during rain, in wind speeds exceeding 12 mph, or temperatures above 89 degrees. For more information or to opt in or out of mosquito control, contact Misti Boggus, local MDA agent, at 312 Safety Drive in Centreville, or by phone, 410-758-0920 ext. 4140.
