Ground-Based WALS Mosquito Control Treatments π -9/2/26
crews will also be conducting ground-based Wide Area Larvicide Spray (WALS) treatments, weather permitting.
πThe areas listed below are areas where our crews are currently planned to operate tonight.
WALS is a targeted mosquito control treatment used to reduce immature mosquitoes before they become biting adults. These applications specifically target potential disease-vector mosquito species, including Aedes aegypti, which can transmit dengue and other mosquito-borne diseases.
π§WHAT YOU MAY SEE
If you see one of our WALS trucks in your neighborhood, you may notice a large plume of liquid droplets being directed upward from the truck into the air.
This is a normal part of the WALS application. The liquid is designed to disperse over the treatment area and reach small, hard-to-access water-holding habitats where mosquito larvae may be developing in neighborhoods.
π¦SO, WHAT ARE WE TREATING?
Aedes aegypti is a particularly challenging mosquito because it often lays its eggs in small containers and other cryptic habitats around homes and businesses.
Our WALS equipment helps us reach areas such as:
π§ Rain gutters
πͺ£ Buckets & containers
πͺ΄ Flower pots & plant saucers
π Tires & other discarded items
π Areas around homes & structures
πΏ Other small, water-holding habitats where mosquito larvae may develop
π WHY ARE WE USING THIS TREATMENT?
Mosquito-borne disease is a regional public health concern, and mosquitoes don't recognize county lines. With increased dengue activity in the greater Tampa Bay area, PCMCD is proactively increasing surveillance and control efforts targeting Aedes aegypti and other potential disease-vector species.
π§οΈ Please remember: WALS treatments are weather permitting. Rain, wind, or other conditions may cause a treatment to be delayed, modified, or canceled.
