How do you make insecticide out of pandan leaves and chili?

No special preparation is reqired. All we de is tie it into a knot so that the weight of the leaves is concentrated and to avoid being blown away by the wind. Then, just plop it down on places where insects especially roaches hang out. You can leave the Pandan leaves for a year or two and it will still be as effective. It's been years since I last saw a rouch in our house.
