Best Temperature for Dubia Roaches to be Kept - an Australian Guide
Temperature is one of the most important factors when keeping dubia roaches alive and healthy. Whether you are storing feeders or starting a breeding a colony, getting the temperature right will directly affect survival, activity levels, and reproduction.
For Australian reptile keepers, dubia roaches are known for being hardy, but they still rely heavily on warmth to function properly. As a popular feeder insect, understanding how temperature affects them will help you reduce die-offs, improve feeding response, and get the most out of your setup. For a broader overview of all feeder options, see our complete guide to feeder insects in Australia.
Quick takeaway: Dubia roaches perform best in warm conditions. Too cold and they slow down or die, too hot and stress increases. Stable warmth is the key to long-term success.
Understanding Temperature and Dubia Roaches
Dubia roaches are a tropical species, meaning they rely on external heat to regulate their body functions. Like all insects, they are ectothermic, so their metabolism, digestion, movement, and reproduction are directly influenced by temperature.
In simple terms, warmer temperatures increase activity and growth, while colder temperatures slow everything down. This is a well-established principle in insect physiology, where metabolic rate rises with temperature until it reaches an optimal range.
- Warm temperatures: increase activity, feeding, and growth
- Cool temperatures: slow metabolism and reduce movement
- Cold conditions: can lead to inactivity and death
- Extreme heat: causes stress and dehydration
What Is the Best Temperature Range
For most setups, dubia roaches do best in a warm, stable environment. A general target range for keeping them healthy and active is around 25°C to 32°C.
Within this range:
- They remain active and responsive
- Feeding and digestion are efficient
- Mortality rates stay low
If you are breeding dubia roaches, slightly higher temperatures within this range tend to increase reproduction rates. If you are only storing feeders, staying on the lower end can slow their metabolism and extend lifespan.
Using heat cord or mats is usually the easiest way to provide your dubia warmth over winter, and just keeping them in a cool area over summer is typically enough. No need to really go full aircon unless it's over 35° where you're located. Keep in mind, some areas of Australia stay pretty warm all year-round. However, those night time minimums can be enough to affect your dubia if it gets cold enough. Just watch your temps closely and adjust as needed.

How Temperature Affects Growth and Reproduction
Temperature has a direct impact on how fast dubia roaches grow and reproduce. Warmer conditions increase metabolic activity, which speeds up development from nymph to adult.
This relationship between temperature and insect development is widely documented in entomology. As temperature increases within a safe range, enzymatic processes and energy use also increase, leading to faster growth cycles.
- Higher temperatures = faster growth and breeding
- Moderate temperatures = stable, slower growth
- Lower temperatures = delayed development or inactivity

What Happens If They Are Too Cold
When dubia roaches are kept below their ideal temperature range, their metabolism slows significantly. This can cause them to become sluggish, stop eating, and cluster together for warmth.
- Reduced movement and feeding
- Slower growth rates
- Increased mortality over time
This is a common issue during colder months in Australia.

What Happens If They Are Too Hot
Excessive heat can be just as harmful as cold temperatures. While dubia roaches tolerate warmth well, very high temperatures increase stress, dehydration, and mortality.
- Increased die-off
- Dehydrated Roaches
- Reduced overall activity
Maintaining proper ventilation is important when using heat.
Common Mistakes to Avoid
- Keeping dubia roaches at room temperature in winter
- Using heat sources without airflow
- Allowing large temperature swings
- Not checking temperature regularly

Final Thoughts
Temperature plays a major role in keeping dubia roaches alive and performing well as feeder insects.
By maintaining a stable, warm environment, between 25-32°, you can reduce losses, improve feeder quality, and prolong life span.
