Notes on Maryland Mosquito Control

Public Notices of aerial larviciding are sent to a broad range of media outlets in the areas being sprayed on the lower shore. This meets FFA requirements as well as lets folks know what the airplanes are doing, including our public information office who may get inquiries. Mosquito Control doesn't use an 800 line.

Maryland maintains a pesticide sensitive individuals list. State law requires notification for some pesticide application categories, but not public health. Individuals in communities participating in adult spraying may opt out by notifying the program.

The MDA Mosquito Control Division is continuing its voluntary cooperative mosquito control program. The program is structured such that interested communities can enter into a cooperative agreement with MDA to receive mosquito control services. The local community must put up a certain proportion of the funding. According to the MDA website, 16 counties are currently enrolled in the spraying program. For more details see www.mda.state.md.us/plants-pests/mosquito_control/mosquito_control_program_description.php. That page includes a list of currently participating communities along with their spraying schedules

Statewide larviciding is done by air on the lower Shore and by ground elsewhere. Normally community spraying begins June 1. Maryland post lists of participating communities on the web, with the scheduled weekly visit (when spraying may or may not occur depending on conditions) indicated where possible.

The principal insecticide used for aerial adulticiding is naled (Trumpet EC) applied at the rate of 0.8 to 1.2 fluid ounce per acre (0.08 to 0.10 lb. a.i./acre). Naled is an organophosphate insecticide which breaks down to the organophosphate insecticide Dichlorvos.

Notes on Delaware Mosquito Control

Insecticides used are registered with the EPA for mosquito control and are applied according to EPA approved label instructions. Delaware residents should get on the state email list for further notifications.
