Dubia Roaches (Blaptica dubia): The Complete Feeder Profile

by

Overview

Dubia roaches (Blaptica dubia) have rapidly become one of the most popular feeder insects for reptile keepers. Originally from Central and South America, these tropical roaches are quiet, virtually odourless, and easy to breed — addressing many of the common complaints about crickets.

Key Benefits

They are quiet (unlike crickets), cannot climb smooth surfaces, are slow-moving enough not to stress reptiles, and have a good protein content (54% DM). They are extremely easy to breed and maintain a self-sustaining colony. They do not bite, smell, or escape easily. Available in a wide range of sizes from nymph to adult.

Storage & Keeping

💡
Storage TipsKeep at room temperature for maintenance or 28-32°C for breeding. Provide egg flats for hiding, fresh vegetables for moisture, and a dry grain-based diet. They can survive for months with minimal care.

Limitations

⚠️
Things to ConsiderTheir chitin content, while lower than mealworms, is still notable in larger adults. The calcium-to-phosphorus ratio (1:4.9) requires supplementation. They need warmth (26-32°C) to breed and are illegal in some regions (e.g., parts of Canada, Florida) due to concerns about establishing wild populations.
