Maryland Department of Agriculture Asks Residents to Act Now to Help Control Mosquito Populations

ANNAPOLIS, MD (April 13, 2023) The Maryland Department of Agriculture’s Mosquito Control Program is urging residents to act now to reduce mosquito populations by reducing standing water on their properties. Aside from being nuisances, mosquitoes can also carry a number of diseases that are harmful to humans and animals, including West Nile Virus and Eastern Equine Encephalitis. 

“Protect yourself and others from mosquito-borne diseases by eliminating potential mosquito breeding sites on your property,” said Maryland Department of Agriculture Secretary Kevin Atticks. “If you start now and do it for five minutes every week, then you should be able to greatly reduce the number of biting mosquitoes in your yard.”

It is important to start before mosquitoes become adults because some mosquitoes can live for several weeks—including Maryland’s biggest nuisance, the Asian Tiger Mosquito (Aedes albopictus). These small black insects have a white stripe on the back and white spots on the legs. They do not fly very far —the majority will fly less than 500 feet—so by eliminating their breeding locations, you may get rid of them in your yard. Asian Tiger Mosquitos breed in anything that holds rainwater, especially toys, tarps, abandoned swimming pools and plastic gutter extenders, which hold water in their ribbing and curves. The department recommends covering gutter extenders with a fine mesh material and a rubber band and to clean the leaves and debris out of them twice a year. 

For items that hold water but cannot be dumped, residents can consider putting a biorational larvicide such as Mosquito Dunks or Mosquito Torpedoes​ into the water.  The pesticides only kill mosquito larvae and are available at most hardware stores and other retailers. For proper application, please read the label of all pesticides before use.
