Circular by design
Insect farming turns organic waste you already have into protein and fertilizer, without a feed supply chain.
When we started farming Black Soldier Flies, we found that egg collection can be a bit annoying, there was not an efficient way of collecting eggs out there. So we developed a system to easily collect eggs that is efficient and aesthetically pleasing.
Maximize Your Production. Simplify Your Harvest. Introducing the BSFL Coop.
Designed for serious breeders, commercial operations, or anyone looking to scale their Black Soldier Fly Larvae (BSFL) production, the BSFL Coop is a professional-grade egg collection system that delivers superior yield and unmatched ease of use. Stop guessing where your adult flies are laying and start efficiently harvesting eggs for a continuous, robust colony.
Engineered for Optimal Oviposition:
-
Egg Cartridges The core of the BSFL Coop features eight modular cartridges, four 1mm and four 2mm, giving the flies different options for comfortable egg laying.
-
Minimal Disruption, Maximum Collection: This system is specifically designed to allow you to collect and harvest thousands of eggs with minimal disturbance to the adult fly environment. Simply remove a cartridge, and replace with a fresh cartridge or gently collect the eggs with a pen knife, and re-suspend it. Eggs typically hatch in 3-4 days.
-
Durable & Sustainable Construction:
-
Frame: The robust, yet lightweight, frame is crafted from Birch Dowels and held together with precise PETG connectors, providing stable suspension for the cartridges. Frame is designed to be placed above or inside attractant container.
-
Cartridges: Made entirely of durable PETG, these cartridges are built to withstand the humid conditions of an active BSFL breeding environment for years of reliable use.
-
The BSFL Coop provides the foundational component for reliable, large-scale BSFL production, ensuring you have a steady supply of new larvae to support your feed or waste management goals. Designed and made to order in Aurora, Colorado.

Maximize egg collection
Gives adult black soldier flies the tight, dark crevices they instinctively seek — so more eggs end up where you can actually collect them.
40× more calcium than mealworms
The larvae you raise have a calcium-to-phosphorus ratio ideal for reptiles, amphibians, and birds — one of the only feeder insects carrying more calcium than phosphorus.
Two things out of one bin
BSFL turn organic waste into protein. The frass left behind is a rich organic fertilizer for the garden.
Made in Aurora, CO
Designed and printed to order in Aurora, CO. PETG, chosen because it holds up in the heat and humidity of an active bin.
