Yates Nature’s Way products are based on natural, low toxic & organic ingredients.
Bacillus thuringiensis var. kurstakiaffects the insect’s digestive system. The bacteria produce a toxic protein that paralyses the insect’s gut. Once a caterpillar eats treated foliage, it stops eating but may take up to 3-4 days to die and drop from the leaf
