Dry coconut shell pieces when subjected to extraction yields crude aqueous solution, which is further purified by distillation method. The larvicidal and antibacterial activity was studied for this crude aqueous solution.3rd and 4th instar larvae of Culex quinquefasciatus were used as clinical subject. Escherichia coli, Staphylococcus aureus, Salmonella typhi and Streptococcus pyogenes were used for antibacterial study.10 % v/v sample of crude aqueous solution gave 100 % mortality within 24hours whereas Salmonella typhi and Staphylococcus aureus were found highly susceptible to crude aqueous solution as it gave 31mm and 24mm zone of inhibition respectively.
