It’s simple! Snap our custom lid onto your fruit fly culture cup and attach the magnetic base. When it's feeding time, just open the dispenser. Flies crawl out one by one directly into your terrarium. No mess, no mass escapes.

DrosoLock is 3D printed from a highly durable wood-blend filament made in the EU. It’s lightweight, strong, and features a premium natural finish. Safety note: The product contains strong magnets. Keep out of reach of small children and away from electronic medical devices (like pacemakers).

Hand wash only using lukewarm water (max 40°C / 100°F) and mild soap if needed. Since DrosoLock is made from wood-infused PLA, it is NOT dishwasher safe! Avoid hot water and do not leave it resting on top of hot terrarium heat lamps or heat mats, as the material can warp.

The DrosoLock lid is custom-designed to fit perfectly on the specific cups included in your package (you get 2 cups with your order). We specifically chose this type of cup because it is much more durable and sturdy than standard deli cups. While it is a standard 0.5L (16oz) size, we cannot guarantee 100% compatibility or a perfect escape-proof seal with other cup brands on the market.

The spinner is made from biodegradable PLA and is precision 3D-printed in the Czech Republic. Each piece is hand-finished and quality-checked to ensure a smooth, solid, and comfortable feel.
