Due to public health concerns about potential mosquito-born diseases the Woods Landing and Revell Downs neighborhoods off Route 50 near Cape St. Claire will be sprayed tonight.
The Maryland Department of Agriculture, in cooperation with Anne Arundel County Department of Health determined the truck spraying was necessary due to the threat of West Nile and Zika viruses.
The spray truck will begin operations after 7:30 p.m., weather permitting.
Officials from both agencies said people should avoid outdoor activities on spray nights.
State and local inspectors will follow up within 24 to 48 hours, going door-to-door to inspect for mosquito breeding sites and could do backyard spraying if necessary to further reduce mosquito populations.
Officials ask residents to cooperate with state and local personnel in the effort.
