Frass is the excrement of mealworms.  Our frass comes from our micro-livestock farm in Mooresville, NC where we grow mealworms on an organic diet of oats and carrots.


Frass is an excellent natural fertilizer and is rich in microbes that are beneficial for soil health.  Additionally, frass is rich in chitin which helps to naturally strengthen plants' immunity against harmful pathogens.


Suggested Application Rates:

General Fertilizer: 1lb of frass per 20 sq ft of garden area.

Potted Plants: Mix 1 cup of frass per cubic foot of potting soil.
