The Philippine Mosquito Ovicidal/Larvicidal (OL) Trap System: DOST Anti-Dengue Device’s ovicidal and larvicidal effect prevent the next generation of mosquitoes from reaching adulthood, thus curbing the Aedes mosquito population. The technology is locally developed and makes use of indigenous materials which is “Paminta” or Black Pepper as the active ingredient/component in the Ovicidal/Larvicidal Pellet. The DOST Mosquito OL Trap System is safe and makes use of an organic and natural material larvicide as compared to the imported synthetic larvicides. It is user- as well as environmentally-friendly. It is non-toxic, easy to use and affordable. The idea is to attract mosquitoes, particularly the Aedes aegypti (dengue carrier), to lay their eggs on the lawanit paddle. The trap creates optimum conditions for this species to lay its eggs: stagnant, clean, clear water, dark area and damp rough surface.
