Build your bin your way. Ready to start your own BSFL operation but want to build it your way? The Blue Grub Farms Bin Kit is a complete BSFL composting kit — everything you need t o transform any standard plastic container (tote, bucket, etc.) into a highly efficient, self-harvesting Black Soldier Fly Larvae composting system. Skip the expensive, bulky pre-built bins and design a system that fits your space, your materials, and your budget. Recently improved. Based on real customer feedback, the kit got an overhaul: a taller entrance with a built-in canopy that keeps rain and irrigation water out of the fly holes, a locking-nut joint so the branches stay put instead of snapping off, and a sturdier harvest ramp with a flared end that seats easily against the bin wall — right where prepupae climb out. What's Included in Your DIY Kit: Prepupae Harvest Ramp: This specially designed ramp allows mature larvae (prepupae) to instinctively crawl out of the food source and up to a collection insert. It's the key to automatic, clean harvesting — no more sifting or digging. Newly redesigned to be sturdier and more durable, with a flared end that gives prepupae more surface to find and makes it easy to seat the ramp flush against the bin wall — where they naturally climb — without cutting the ramp hole into a corner. Collection Insert: Sits outside your main bin, ready to receive the self-harvested prepupae from the ramp. Just lift and collect. Adult Fly Entrance Pod (the "Bintrance"): Guides newly emerged adult Black Soldier Flies into the breeding area, helping to keep your colony contained and focused on reproduction. Now built taller with a canopy over the top, so rain and irrigation water can't run down into the fly entrance holes and soak your bin. The branches lock on with a secure nut joint for durability. The "Egg Tree" Laying Surfaces: Modeled after nature, these surfaces — complete with decorative "leaves" — mimic the ideal narrow, protected spaces where female BSFL prefer to lay their eggs. This maximizes egg production, ensuring the constant, sustainable growth of your colony. Why Choose the Bin Kit? Customize Your Colony: Use the container size and material that works best for your setup. Maximize Egg Laying: The proprietary Egg Tree design is proven to boost your colony's reproductive success. Automate Harvesting: The Prepupae Ramp lets your colony harvest itself — no digging, no sorting. Sustainable Loop: BSFL eat your kitchen scraps and produce nutrient-dense larvae plus frass. This kit closes the composting loop. Just add your container, some organic waste, and your initial starter batch of larvae. Bin not included. New to BSFL?
