Mosquito Management Plan
Every year, St. Tammany Parish Mosquito Abatement District (STPMAD) updates and follows a mosquito management plan in order to respond to shifting populations of nuisance and pathogen-carrying mosquito species. Mosquito traps are set across the Parish twice a week to better understand where mosquito problems may be developing. Certain species of mosquitoes collected in these traps are sent to Louisiana State University and tested for the presence of dangerous pathogens, including the West Nile and Zika viruses. Surveillance data directly influences where mosquito abatement intervention is necessary, as well as where it is not.
Mosquitoes are most abundant in hot summer months, a time period where STPMAD ramps up mosquito abatement efforts considerably. Insecticides targeting mosquito larvae (larvicides) and adults (adulticides) are often used more frequently in hot summer months in response to faster-developing and more numerous mosquitoes. When mosquitoes are found to be carrying dangerous pathogens (including West Nile), STPMAD devotes additional time to surveillance and treatment in affected areas.
