BTI Mosquito Briquets are a sustained-release larvicide that conveniently floats right on the water surface. These briquets can be used in virtually any standing water site where mosquito larvae grow. As the briquets float, BTI (or bacillus thuringiensis israelensis, a natural mosquito-killing biocontrol agent) is slowly released at the water’s surface and gradually settles in the water where it is consumed mosquito larvae. Bti kills mosquito larvae before they are able to grow into mature, biting adults, eventually controlling the mosquito population. Additionally, the toxin will continue to be released into the water for a period of 30 days or more, providing continuous kill. Each briquet will effectively treat up to 100 square feet of surface water regardless of depth.
