Dairy industries worldwide discard ghee sediment waste and clarified butter sediment waste (CBSW) in bulk every day. The aim of the present study was to explore the possibility of utilising the CBSW to prepare culture media so as to produce mosquitocidal bacteria. The bacteria achieved complete degradation of CBSW for its toxin synthesis. The bacterial growth, biomass, toxin production and larvicidal activity against mosquito vectors were comparable with those using conventional culture medium (NYSM) as a control. We obtained a cell mass yield of 9.7 g/L and larvicidal activity (LC 50 and LC 90 ) of 0.0036 mg/L and 0.01 mg/L against Culex quinquefasciatus using bacteria grown in CBSW. Cost‐effective analysis indicated that CBSW is highly economical.
