Black Soldier Fly (BSF) Eggs. These eggs are shipped from Soldier Fly Technologies, a California based Black Soldier Fly company. Soldier Fly Technologies manages the full life cycle of the BSF insect, including producing its own insect eggs. These insects live indoors through all stages of their life cycle, year-round. BSF are raised on grains (NO MANURE OR KITCHEN WASTE). Every 1 gram of BSF eggs contains approximately 37,000 eggs. Each shipment will arrive with a specified Use On date indicating the optimum date on which the container should be opened and the larvae placed onto a food source. These larvae are resilient and will consume a wide variety of food sources. Following the Use On date will eliminate the guesswork, and yield optimum results!
