Black soldier fly larvae are a high fat worm loved by many reptiles! They are raised on a probiotic-treated grain & grass diet, and contain high levels of calcium. Their balanced Calcium:Phosphorus ratio makes them the ideal staple diet for your reptiles, with no need for additional dusting. To store, keep them in their lidded cup at room temperature. If you plan to keep your worms longer than 2 weeks, moving the container to a cooler spot (50-60 degrees) will help extend their life span. They also make great composters for your garden! Live Arrival Guaranteed!
