Down To Earth’s Insect Frass is an all-natural fertilizer produced through sustainable insect farming and derived from the larvae manure and exoskeletons of black soldier flies. The larvae are raised on pre-consumer food waste collected from local grocery stores, produce distributors and food processors. After harvesting, they are turned into a renewable source of high value protein for animals and beneficial nutrients for plants. DTE Insect Frass is an excellent fertilizer for all types of plants and shares many of the same traits as other popular organic soil amendments such as bat guano and worm castings.
