Mosquito Treatment Centers

There are currently 35 treatment zones in Brunswick County. Brunswick County implements adulticiding activities when mosquito thresholds have been met. The landing count threshold for Brunswick County is 7 mosquitoes per minute using standard landing count procedures. The Asian tiger mosquito, Aedes albopictus, will be counted separately from other biting mosquitoes during landing counts. Additionally, adulticiding operations once initiated will continue for the duration of the environmental event that triggered the emergence of the mosquito population.  Adult mosquito populations typically survive for 3 to 4 weeks, depending on time of year.

As the adult nuisance populations wane, the risk of disease transmission increases. While mosquito populations may fall below the nuisance threshold, it is important to continue adulticide operations until the increased risk of disease transmission is reduced to acceptable levels.

Biomist 3+15 is the current product used to manage adult mosquito populations by the county. Typical spray times are between 5:30 p.m. and 11:00 p.m. depending on weather conditions. Our mosquito sprayers are equipped with Smart Flow Technology, providing the driver with increased treatment flexibility, while improving the accuracy of each application. As a precautionary measure, people and pets should go indoors when they see the mosquito sprayer coming. People with severe allergies should notify Operation Services.
