That buzzing you hear from the ditch may soon not only be the beating wings of flitting mosquitoes but the propellers of a large, flying mosquito killer.

In the United States, officials of a local town are close to buying a new aerial drone able to fly, hover and spray up to 20 pounds of chemicals at a time in hard-to-reach areas where mosquitoes breed. Another private mosquito control company is using drones to scout for breeding sites.

The drone can spray with a precision that would allow workers to save on cost and limit environmental impact compared with more broadly applied aerial methods. The drone, for instance, could be used to spray a ditch along a heavily traveled road with no shoulder that’s traditionally been unsafe and hard to spray.

The remotely operated drone won’t replace the trucks and planes that already spray periodically through the parish and which kill the adult mosquito.
The drone, which can spray 80 acres in a day’s work, will be used to kill larvae growing in standing water, taking out the next generation of blood suckers before they take flight. That’s actually one of the most important things you can do to control the population, is larvicide.
