The state Department of Environmental Management will distribute mosquito larvicide to Rhode Island communities starting Tuesday. Cities and towns use the product to kill mosquitos in catch basins, where they most commonly breed.
The state has been supplying cities and towns with mosquito larvicide ever since West Nile virus emerged 14 years ago. They use an environmentally-friendly product that comes in a briquette, about the size of two ice cubes. Town officials put one in each storm water catch basin and it kills larvae for six months.
