The Haffkine Research Institute has received samples of various brands of oil used to kill mosquito larvae from the BMC.
The institute will check out the oils in order to test their efficacy. "After we get the test reports, we will procure the brand that is found to be the most effective in controlling larvae,'' Dr Arun Bamne, chief insecticide officer of the BMC told the Times of India.
Dr Ramaiya Mira, head of the Zoonosis department, Haffkine Research Institute said that the oil would be tested on mosquito colonies.
The report from the institute is expected on Thursday.
