I live in the Caribbean. I don't understand why some
DIY mosquito larvae directions suggest using organic decaying matter (potato peels, bread crums, etc).
I rather use water from a tank, place a small sponge filter, use an easy to remove plant and leave alone outdoors for a week or so, just feed the tank with a pinch of fish food every other day. In a week or so, grab the container, remove the plant, filter the water through a fish net and there you go.
Risk: If you let too much time pass by, Mosquitoes will hatch and guess who becomes life food for the females!
