Hillsborough County is taking its battle against mosquitoes to new heights, quite literally. Residents may soon spot a helicopter hovering at low altitudes as the county's Mosquito Management Services executes targeted anti-larvae operations. Since 1950, Hillsborough has deployed aerial technology to curb the pesky insect populations. Historically a rented airplane did the job, then a repurposed military craft came into play; now it's a chopper's turn to keep the skies—and the grounds below—less buzzed.
For the curious and concerned, the county is throwing its doors open for Public Service Day on March 29, from 9 a.m. to noon. At 9805 Sheldon Rd., Tampa, FL, you can meet the pilot, inspect the helicopter up close, and chat with the experts about their mosquito-fighting strategies. The event is also a chance to adopt some mosquitofish—or Gambusia—that gobble up mosquito larvae and help keep populations down, according to the Hillsborough County's announcement.
What's the deal with the chopper? It's cleared for low flying by the Federal Aviation Administration (FAA), necessary for making sure the larvicide gets where it needs to go—the mosquito larvae's watery homes. The products used from above are EPA-approved and, the county assures, safe for humans and wildlife. In the name of public health and comfort outdoors, the County conducts these flights, keeping an eye out for prime breeding grounds and hard-to-reach spots that require such high-flying solutions, the Hillsborough County's press release states.
The active ingredient in this aeronautical assault is called Bacillus thuringiensis israelensis (BTI) — a naturally occurring bacterium dusted onto corncob granules. When mosquito larvae take a nibble, their digestive systems are disrupted and they're stopped in their tracks before reaching adulthood. This method targets larvae specifically, thereby cutting off the problem before it truly takes wing, without risks to other creatures. Timely too, treatments kick off at sunrise, and the county is introducing evening spraying sessions for adult mosquitoes. Keep informed about the schedule by signing up for alerts on the Mosquito Spray Notifications page, the county suggests.
Why this persistent aerial offensive? Because mosquitos don't play nice. Species like Aedes taeniorhynchus are particularly aggressive and thrive in remote areas like salt marshes, far from the reach of trucks and foot crews. Without these aerial interventions, those areas could become hot spots for mosquito infestations, taunting the rural tranquility and deterring visitors, explains the Hillsborough County's announcement.
