How to Breed Dubia Roaches in Australia | Beginner Breeding Guide
Breeding dubia roaches is one of the most effective ways to maintain a steady supply of feeder insects. While dubia roaches are relatively easy to breed compared to other feeders, their reproduction depends heavily on temperature, setup, and consistency.
This guide covers how to start a simple breeding colony, what conditions are needed, and how Australian climate affects results. For a broader overview of feeder insects, see our complete guide to feeder insects in Australia.
Quick takeaway: Dubia roaches breed steadily when kept warm, well-fed, and low-stress. In Australia, many areas won't need to heat their colony during the warmer months.
Understanding Dubia Roach Breeding
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 we work in an extremely well ventilated environment, we suggest you do as well!
Dubia roaches reproduce by giving birth to live young rather than laying eggs. Females carry developing eggs internally and produce small nymphs once the brood is ready.
Once a colony is established:
- Females produce young on a regular cycle (~65 days)
- Reproduction is steady rather than rapid
- You can start feeding from your colony regularly

Starting a Basic Breeding Colony
A small-scale breeding colony does not require complicated equipment. A simple setup is enough to get results.
Basic setup includes:
- Plastic tub: smooth sides to prevent escape
- Egg cartons: increase surface area and reduce stress
- Ventilation: mesh-covered holes for airflow
- Heat source: heat mat or warm location
- Food and moisture: dry food plus fresh produce or water crystals
A starting colony should include a mix of adult males and females. Without adults, breeding will not occur. If you want to ensure young adults, it's worth buying large or XL dubia and waiting a couple of months extra. It takes longer, but this way you'll know you will get a full breeding cycle out of your original roaches.

Male to Female Ratio
The ratio of males to females affects breeding efficiency, but more males does not mean faster results.
- A small number of males can service multiple females
- Too many males can create unnecessary disturbance
- Balanced colonies tend to perform more consistently
In most small setups, keeping fewer males than females is more efficient and reduces stress within the colony. Most sources suggest a ratio of between 1:3 and 1:7. For a small setup, it doesn't have to be perfect, but ideally ensure less males then females.
Temperature and Breeding Speed
Temperature is the single biggest factor affecting reproduction. Dubia roaches require consistent warmth to breed effectively.
- Warm conditions increase breeding activity
- Cool conditions slow or stop reproduction
- Stable temperatures produce the best results

How Australian Climate Affects Breeding
Australia’s climate varies significantly depending on location, and this directly impacts dubia roach breeding.
- Warmer regions (e.g. QLD, NT): may not require heating during warmer months
- Temperate regions (e.g. NSW, VIC): may need heating during cooler months
- Cooler regions: breeding often slows or stops in winter without heat
In many parts of Australia:
- Dubia roaches can survive winter temperatures without heat
- However, breeding activity may reduce significantly
- Consistent warmth is required for steady reproduction
This means some keepers rely on seasonal breeding cycles, while others maintain heat year-round for consistent production. In many area's of Australia, you can expect your dubia to breed throughout all the warmer months, until night time lows start getting below 20°C.
Once winter hits, in warmer areas your colony will likely survive without heat, but breeding will slow. However, if in a much cooler climate, it's a good idea to heat your colony.
How Long Until You See Babies
One of the most common questions is how long it takes for a colony to start producing nymphs.
- New colonies may take time to establish
- Females require time after maturity before producing young. The first young might not be seen until 2 months after you're adults have matured
- Once established, production becomes steady
It is normal for breeding to feel slow at the start. Patience is important when setting up a new colony.
Why Dubia Roaches Might Not Be Breeding
If your colony is not producing, there is usually a specific reason.
- Temperature too low
- Insufficient or inconsistent feeding
- Colony not mature
- Incorrect ratio of males to females
- Stress from overcrowding or disturbance
Even one of these factors can slow breeding significantly.
Common Mistakes to Avoid
- Expecting immediate breeding results
- Keeping the colony too cold
- Using too many males
- Not feeding/hydrating consistently

Final Thoughts
Breeding dubia roaches is straight forward once the basics are in place. Temperature, consistency, and colony balance are the key factors that determine success.
In Australia, understanding how seasonal changes affect your setup can make the difference between a slow colony and a steady, reliable feeder supply.
