Repids, a Chulalongkorn University innovation, turns used vegetable cooking oil into a non-toxic organic insecticide.
Repids helps address pollution from grease-clogged drainage systems and improper used cooking oil management.
The Repids team has chosen to make the formula openly available so that communities and community enterprises can produce it themselves.
The original Repids formulation required a concentration of as much as 2% to achieve effective insect control.
