I am growing basil and a small green caterpillar eats the leaves up. They are very small and hard to find. I don't want to spray, any suggestions?

Bacillus Thuringiensis (Bt) spray can quickly eradicate these leaf and stem-eating worms. It is a safe, biological insecticide. In fact, Bt is a bacterium which is toxic to many moth and butterfly larvae (caterpillars) and will not harm the plants or other beneficial creatures.
