Insect Frass

OASCO carries the LARGEST inventory of Enterra BSF Frass (Enterra Natural Fertilizer) in the USA! We purchase by FULL Truckloads, and provide the best pricing available.

Black Soldier Fly Frass is superior to worm castings in many ways.  It provides MUCH higher levels of NPK PLANT AVAILABLE nutrients (the highest of ANY organic material as far as we know), as well as higher levels of chitin and cellulose. THIS IS NOT TO SAY THAT WORM CASTINGS ARE NOT AN IMPORTANT PART OF ORGANIC INPUT MATERIAL SOIL FEEDING PROGRAMS! Our Gold-n-Frass Mix COMBINES the benefits of worm castings WITH insect frass, for what we consider is THE BEST ORGANIC INPUT MATERIAL AVAILABLE ON THE MARKET!  We recommend using both worm castings and insect frass for organic growing.
