Ground-Based WALS Mosquito Control Treatments 🚛 -9/8/26

crews will also be conducting ground-based Wide Area Larvicide Spray (WALS) treatments, weather permitting.

📍The 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.

💧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.

🦟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:
💧 Rain gutters
🪣 Buckets & containers
🪴 Flower pots & plant saucers
🛞 Tires & other discarded items
🏠 Areas around homes & structures
🌿 Other small, water-holding habitats where mosquito larvae may develop
🌎 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.

🌧️ Please remember: WALS treatments are weather permitting. Rain, wind, or other conditions may cause a treatment to be delayed, modified, or canceled.

🚁 One region. One public health fight.

Our PCMCD helicopter just launched to assist with the dengue outbreak response in Hillsborough County.

Dengue doesn’t recognize county lines. Our efforts in Hillsborough protect Pasco residents—and the thousands who travel between our communities every day across the Tampa Bay region to live, work, and play.

Stopping dengue is a shared responsibility. 🦟

You can help us eliminate mosquito production sites around your homes and businesses—especially containers like flowerpots, plant saucers, clogged gutters, and old tires.

Protect yourself, too: wear long sleeves, long pants, shoes and socks, and use a US EPA-registered insect repellent.

Together, we can stop dengue.

🦟 A MESSAGE TO ALL RESIDENTS - Dengue

🎥 NEXT VIDEO TOPIC: “The Importance of Mosquito Control & What You Can Do to Help Protect Public Health”

Please Watch & Share!

Mosquito control is more than eliminating a nuisance — it is an important part of protecting public health. And everyone has a role to play.

The best way to fight mosquitoes starts with prevention — and it starts at home.

In this video, we’ll explain why mosquito control matters and the simple steps every resident can take to help reduce mosquito populations and prevent mosquito bites.

🪣💧 DUMP & DRAIN: Regularly check your yard and surrounding areas for anything that can collect water. Dump it out or drain it.

You can also help protect yourself and your family by:

💧 Dumping & draining standing water regularly
🦟 Using U.S. EPA-registered mosquito repellent
👕 Covering exposed skin when outdoors
🏡 Removing containers and items that can hold water

PCMCD continues to increase surveillance and mosquito control efforts, including daytime aerial liquid larvicide treatments using low-flying helicopters, along with ground-based mosquito control.

Mosquito control is a community effort. Your actions at home matter.

🦟 Dump. Drain. Protect. Fight the Bite.

REGIONAL RESPONSE. LOCAL PROTECTION. 🦟🚁

Today, is deploying our aircraft and personnel to Hillsborough County to assist with the ongoing dengue virus outbreak response.

We want to be transparent with our residents: today’s operation is outside PCMCD’s normal jurisdiction. However, our involvement directly supports our mission of protecting the health of Pasco County residents.

Dengue and the mosquitoes that transmit it do not recognize county lines. The Tampa Bay region is highly interconnected, with thousands of people traveling between Pasco, Hillsborough, Pinellas, and surrounding counties every day for work, school, healthcare, recreation, and other activities. Interrupting an active dengue transmission cycle in a neighboring county reduces the risk of continued regional spread and helps protect our residents here at home.

PCMCD is providing specialized aerial wide-area larvicide operations as part of the coordinated public-health response. Our Airbus H125 helicopter will apply a liquid Bti (Bacillus thuringiensis israelensis) mosquito larvicide to help reduce production of Aedes aegypti—the primary mosquito responsible for dengue transmission in our area.

Residents in the treatment area may see our orange helicopter flying very low over residential and commercial neighborhoods during daylight hours, beginning as early as 8:00 a.m., weather permitting. Multiple straight passes over the same general area are expected and are a normal part of the application process.

Pasco remains our priority. Our participation in this regional response has been structured so that PCMCD retains the personnel, equipment, and operational capability necessary to continue protecting Pasco County throughout this effort.

We believe stopping dengue transmission as close to its current source as possible is one of the most effective ways we can help prevent it from becoming a larger regional problem.

Protecting our community sometimes means working beyond a boundary on a map. Today, we're doing both.
