This insect frass is from a local bug farm that we are working with. It is a clean, wheat bran fed insect frass with alot of exoskeletons of bugs which is great. They are made of pure chitin which is a great addition to organic soil. Insect frass is a natural plant food. It is the excrement of herbivore insects. Key benefits from frass are chitin, microorganisms and organic nutrients from plants. Insect frass has every functional group of beneficial bacteria, fungi and protozoa that will retain and cycle nutrients in the root zone. Insect frass provides every primary and secondary nutrient available.
