With the monsoon comes the rains and with the rains come the puddles. And, if fourth-grade Science has taught us anything, it is that with these puddles come the mosquitoes. But what is lesser known to the public is that Blackfrog Technologies, a product development company, has been working for the past six months on a larvicide cake, formulated by PhD scholar Dr Dhoolappa Melinamani. This cake, when thrown in water, can flush out larvae over a 12-day period.

“We use the feathers of chicken, which is basically poultry waste,” says the CEO of Blackfrog, Mayur Shetty. The 24-year-old also adds that while most larvicides could harm other insects like grasshoppers, the cake only targets mosquitoes, black flies and fungus gnats. It’s so well formulated that, “it’s okay for your pet to drink the water too,” says the Manipal-born co-founder. The project is now in the field evaluation stage, for which the 12-member team is in talks with the Udupi Panchayat in Karnataka

Blackfrog is currently being incubated by the Manipal University Technology Business Incubator (MUTBI), an initiative of Manipal University. Having grown up on campus (as his father is a professor there), Shetty would often witness students leaving the city in pursuit of better job opportunities. So when he co-founded Blackfrog Technologies with Donson D’Souza in 2015, it was also for the purpose of job creation. Shetty notes that aside from parents supporting their children, the government too must step up to allow for more entrepreneurs to step forward.
