How Fast Do Dubia Roaches Reproduce | Breeding Speed Guide
Dubia roaches are known for being one of the most reliable feeder insects to breed, but their reproduction speed depends heavily on setup, temperature, and colony structure. While they do not reproduce as quickly as some insects, they can steadily produce large numbers when conditions are correct.
For Australian reptile keepers, understanding how fast dubia roaches reproduce helps with planning feeder supply. For a broader overview of feeder insects, see our complete guide to feeder insects in Australia.
Quick takeaway: Dubia roaches reproduce steadily rather than rapidly. Warm temperatures, a proper male-to-female ratio, and low-stress conditions are the biggest factors affecting breeding speed.
How Dubia Roaches Reproduce
Dubia roaches are ovoviviparous, meaning females carry eggs internally and give birth to live young rather than laying eggs externally.
Under suitable conditions:
- Females produce a brood roughly every 65 days on average
- Each brood typically contains around 20 to 35 nymphs
- Reproduction continues steadily once the colony is established
This steady cycle is what makes dubia roaches ideal for long-term, consistent feeder production, but not as ideal for rapid short-term output, like crickets, or even wood roaches (woodies), who reproduce much faster.
How Long Until Dubia Roaches Start Breeding
Dubia roaches do not reproduce immediately after reaching adulthood. There is a delay before females begin producing young.
- Sexual maturity is typically reached 4-8 months after hatching - depending on growth rate
- Once mature, females may take several weeks to produce their first brood
- New colonies often take time to “kick in” before production becomes consistent
This is why new colonies can feel slow at first. Once established, reproduction becomes much more predictable.
Male to Female Ratio and Its Impact
The ratio of males to females plays a role in breeding efficiency, but more males does not always mean faster reproduction.
- Too few males can limit breeding opportunities
- Too many males can cause unnecessary competition and stress
- A balanced ratio supports consistent mating without overcrowding
In most setups, a lower number of males compared to females works well. Excess males do not significantly increase production and may reduce efficiency if they create disturbance within the colony.
How Temperature Affects Reproduction Speed
Temperature is one of the most important factors influencing how fast dubia roaches reproduce.
- Warmer conditions: increase metabolism and breeding activity
- Moderate temperatures: maintain steady reproduction
- Cool conditions: slow or stop reproduction entirely
Dubia roaches require consistent warmth to breed effectively. If temperatures drop too low, females may stop producing broods altogether.

How to Tell If Dubia Roaches Are Mature
Identifying sexually mature dubia roaches is important when building a breeding colony.
- Males: fully developed wings covering the body
- Females: broader shiny body with small wing stubs
- Behaviour: active movement and interaction within the colony
Only fully matured adults will reproduce. Large nymphs will not breed until they complete their final molt.
Why Your Dubia Roaches Might Not Be Breeding
If your dubia roaches are not reproducing, it is usually due to environmental or setup issues.
- Temperature too low
- Insufficient food or poor nutrition
- Incorrect male-to-female ratio
- Stress from overcrowding or disturbance
- Colony not yet mature
Even one of these factors can slow or completely stop reproduction.

Common Mistakes to Avoid
- Expecting instant reproduction from a new colony
- Keeping them too cold
- Overloading the tub with males
- Not feeding the colony consistently

Final Thoughts
Dubia roaches reproduce at a steady pace when conditions are correct. While they are not the fastest breeding feeder insect, their consistency and reliability make them one of the best long-term options.
By maintaining proper temperature, nutrition, and colony balance, you can significantly improve reproduction rates and build a sustainable feeder supply.
Important Note: If considering breeding Dubia Roaches, note that it's very common to become allergic with the constant exposure and cleaning experienced when maintaining a colony, compared to just keeping them as feeders. Here at Reptifauna, PPE is worn whenever working with Dubia, and always in an extremely well ventilated environment.
