Summit BTI Briquets, Amvac floating sustained-release larvicide for long-term control of mosquito and psychodid fly larvae.


For over 25 years, fast-acting Summit B.T.I. Briquets have been the industry standard in extended release B.T.I. formulations for control of mosquitoes in the larvae stage. Few products match their record of reliable and environmentally compliant performance.


Summit B.T.I. Briquets are a small circular cork matrix that floats on standing water. As the briquet slowly dissolves, it releases a bacterium which is toxic to all species of mosquito larvae. The active ingredient in Summit B.T.I. Briquets is bacillus thuringiensis subspecies israelensis (B.T.I.) which is a common soil-borne substance. B.T.I. is a bacterium that is deadly to mosquito larvae but harmless to other living things, for instance, aquatic insects, fish and other aquatic life are not harmed.


Summit B.T.I. Briquets can be used any place water collects and allows mosquitoes to breed and remain for periods of time. After female mosquitoes lay their eggs in or near standing water treated with a Summit Bti Briquet, the larvae that hatch feed on the B.T.I. The B.T.I. will kill the mosquito larvae before they can develop into adults capable of spreading diseases.
