The Brief Nearly 600,000 male mosquitoes will be released in some DC-area neighborhoods to fight the biting mosquito population. The initiative, led by Silver Spring-based Bee Safe Mosquito Control, aims to reduce the biting mosquito population without resorting to widespread pesticide spraying. The released male mosquitoes carry a harmless bacterium that renders female mosquito eggs unable to hatch after mating. Bee Safe Mosquito Control is partnering with residential clients rather than municipal governments. The company currently serves 25 homes across Bethesda, Silver Spring, Takoma Park, and Washington, D.C., releasing about 1,500 male mosquitoes per property each week.
