The Bin Kit
3D-printed self-harvesting conversion kit. Turns any tote into a working Black Soldier Fly larvae bin in about three weeks.
The Coop
Black Soldier Fly egg collection system. Modular PETG cartridges on a birch dowel frame — for serious BSF keepers.
Clippie
Universal Black Soldier Fly oviposition clip. Snaps onto any bin lip for clean, repeatable egg-laying — the cheapest way in.
The Tree of Life
12-leaf oviposition system that triples your egg-laying surface. 3D-printed PETG, drops right into any standard BSFL bin.
The Grub Escape
Self-harvesting ramp system. Prepupae crawl out of the bin on their own into your collection container. 3D-printed PETG with hardware included.
Live & dried larvae — on the way.
We're working through state feed registrations so we can ship our Black Soldier Fly larvae direct to your reptiles, chickens, birds and fish. Drop your email and we'll let you know the day they go live.
Frassquatch fertilizer — on the way.
Frass is the nutrient-rich byproduct our larvae leave behind — and it's a serious organic fertilizer. We're finishing our state fertilizer registration before we sell it. Get on the list.
Printed in Aurora
Every part is designed in our backyard and printed in PETG at our small farm in Aurora, CO.
Made to order
We print to fulfill — no warehouse of plastic sitting around. Ships within 7 days of your order.
Expert support
Stuck? Email us. We've been raising BSFL since 2023 and we'd rather help you succeed than ship you replacements.
Circular by design
Insect farming recycles organic waste into protein and fertilizer. It's the most sustainable feed on earth.
