Insect Frass is 100% Organic plant food and so much more... Insect Frass naturally contains the nutrition plants require, beneficial micro-organisms and the only immediately plant-available source of Chitin. Chitin fortifies a plant from the inside out causing an auto-immune response that signals a plant to produce natural toxins which fend off its natural enemies. Insect Frass is NOT a pesticide. Insect Frass is NOT a fungicide. Insect Frass will NOT put insects into your garden.
