Summit Mosquito Bits is a highly selective microbial insecticide (BTI) effective against mosquitoes in a variety of habitats. Kills Mosquito larvae that transmit West Nile Virus, Encephalitis, Malaria, Dengue Hemorrhagic Fever. When spread uniformly over the surface of containerized water the BITS release a biological mosquito larvicide at the water's surface. This larvicide gradually settles in the water where it is eaten by mosquito larvae growing there. Summit Mosquito Bits may be used in all types of containerized standing water sites where mosquito larvae grow. The Bits will give a quick kill within 24 hours. For more residual long-term control please consider the use of Summit Mosquito Dunks after applying Summit Mosquito Bits. Summit Mosquito Bits can be applied to areas that contain aquatic life, fish and plants. Can be applied to areas used by or in contact with humans, animals, horses, livestock, pets, birds or wildlife. Apply to standing water found near the house such as water gardens, tree holes, stock tanks, animal watering troughs, rain barrels, bird baths, roof gutters, etc. May also be used to control Fungus Gnats. Sprinkle or spread the granules over the soil until the area is covered. Water will release the BTI into the soil where the larvae of the Fungus Gnats will feed on it and die. Repeat this process for a three week period for control. If Fungus Gnats reappear, repeat process for another three week period.
