The Vector Control Program has been conducting monthly aerial mosquito larvicide applications to difficult-to-access areas that are known for mosquito breeding.
The larvicides used by the Vector Control Program act specifically on mosquito larvae and will not harm other wildlife.The larvicide used is called VectoMax, which is a mixture of Bacillus sphaericus and Bacillus thuringiensis israelensis. It is applied by a helicopter every three to four weeks to the vegetation in the water bodies. The larvicide listed above is made from bacteria that only affect mosquito larvae. The bacteria kill the larvae before they can develop into biting adults.
