Mosquito Bits are a highly selective microbial insecticide effective against mosquitoes in a variety of habitats. When spread over the surface of containerized water the Mosquito Bits release a biological mosquito larvicide at the water's surface. Mosquito Bits (larvicide) gradually settles in the water where it is eaten by mosquito larvae growing there, killing the larvae before it becomes an adult. Mosquito Bits may be used in all types of containerized standing water sites where mosquito larvae grow. They will give a quick kill within 24 hours.


Sprinkle one teaspoon per 25 square feet or one tablespoon per 75 square feet (1/2 lb. or 8 oz. per 2,178 square feet or 30 oz per 8,000 square feet.) When spread over the containerized water surface, the BITS release a biological mosquito larvicide at the water's surface. Its kills the larvae before it turns into an adult mosquito. 

A seven to fourteen day interval between applications should be employed. For more residual long term control, we recommend the use of  Mosquito Dunks after applying Mosquito Bits. May be applied to areas that contain aquatic life, fish, and plants. Maybe be applied to areas used by or in contact with humans, animals, horses, livestock, pets, birds or wildlife. Except finished, treated human drinking water sources.
