Description
Give your pets a premium nutritional boost with our high-quality Black Soldier Fly Larvae. Often sold under names like CalciWorms or ReptiWorms, these robust, wiggly grubs are an irresistible, high-value treat that stimulates the natural hunting instincts of insectivores.
The Ultimate Calcium Solution
Unlike crickets or mealworms, BSFL do not require calcium powder dusting. They naturally possess a perfect calcium-to-phosphorus ratio (approx. 2:1). This makes them an excellent staple choice for juvenile reptiles experiencing rapid bone growth, breeding females looking to replenish calcium stores, and rescued animals recovering from nutritional deficiencies.
Why Choose Black Soldier Fly Larvae?
    • Highly Digestible: Their soft exoskeletons make them incredibly easy for pets to digest, reducing the risk of impaction.
    • Long Shelf Life: They keep exceptionally well for weeks without needing a complex setup or daily feeding.
    • Natural Antimicrobial Properties: Rich in lauric acid, BSFL help boost your pet’s immune system and support overall gut health.
    • Enticing Movement: Their active wriggling motion quickly catches the eye of picky or stubborn eaters.

💡 Storage & Care Instructions
    • Keep the larvae in their shipping container with the provided packing media.
    • Store at a cool room temperature—ideally between 10°C and 15°C—to slow down their metabolism and maximize their lifespan.
    • Do not refrigerate them in standard refrigerators, as temperatures below 10°C can be fatal.
    • Note: Over time, the larvae will darken into a pupal stage. They are still highly nutritious and safe to feed out at this stage, or you can let them hatch into harmless, slow-flying flies for an exciting aerial treat for chameleons and frogs!
