The Ergonomic Feeding Dish is a compact, attractive, and smartly designed glazed clay bowl that’s great for holding Dubia roaches at feeding time. It can also be used to hold other small feeders like mealworms, superworms, and more.
At 3.75 inches, the dish itself is about the diameter of a softball. However, its height varies. It starts out at 1.25 inches in the front to allow easy access to food. The height gradually increases as you move toward the rear, where it reaches a maximum of about 2 inches. The bowl is glazed inside and out, making the walls too slippery for Dubia to climb. They generally can’t escape unless their body is longer than the height of the wall – and sometimes not even then. There is a 1/8-inch inward-facing lip around the rim that helps keep in larger insects.
So what size Dubia can you feed with this Dish? Any size, actually. The Ergonomic Dubia Roach Feeding Dish reliably holds up to about 1-inch Dubia. Any larger and some may escape, but even then not always. How reliably the Dish keeps larger roaches in depends on a few things:
First is how many roaches you put in the Dish. They can climb on each others backs, so the more roaches in the bowl, the more likely the larger ones will find an opportunity to climb out.
Second, it depends on time. Dubia tend to seek dark places, so when the dish is placed in a brightly lit reptile enclosure, for example, they tend to head for the shadows and not attempt to escape. They are more active at night when it’s dark, so they may escape if they’re left in the Dish overnight.
The Ergonomic Dubia Roach Feeding Dish comes in two colors: Blue and green.
