An effective mosquito larvicide and bio-mosquito coil has been prepared by use of above herbals to establish a powerful knockdown effect against larvae and adult mosquitoes, when compared with marketed synthetic products. A Mosquito coil (0.6 cm thickness) was prepared manually and shade dried and it has been demonstrated to tribal people.

Field trials have been conducted at the breeding sites of mosquitoes at stagnant water bodies and insect pests at the Agricultural forest ecosystem at tribal settlement at Nilgiris and Maruthamalai Hills. Bioassays have also been conducted against non-target organisms such as copepods, Mesocyclops aspericornis, Guppy fish, Poecilia reticulata and earthworm, Eudrilus eugeniae species.
