Summit B.T.I. Briquets

Summit Chemical

For more than 35 years, fast-acting Summitâ„¢ B.t.i. Briquets have been the industry standard in extended release B.t.i. formulations for control of mosquitoes in the larval stage. Few products match their record of reliable and environmentally benign performance. Summit B.t.i. Briquets release larvicide B.t.i, a natural bacterium found in soils, which mosquito larvae ingest, dying before they become adults.
