Best Temperature for Woodies (Wood Roaches)
Temperature is one of the biggest factors affecting how well woodies survive, feed, and breed.
If your setup is too cold, too hot, or constantly fluctuating, woodies will usually become less active, eat less, and breed slower. Getting the temperature right makes a major difference to long-term results.
Quick answer: The ideal temperature for woodie roaches is generally around 24°C to 30°C, with warmer conditions usually improving activity and breeding. Temperatures that are too low slow them down, while excessive heat increases stress and dehydration risk.
Why Temperature Matters for Woodies
Like other feeder insects, woodies are cold-blooded and depend on their surroundings to regulate body function.
Temperature affects:
- activity levels
- feeding response
- growth speed
- breeding rate
- overall survival
This means even a decent setup can underperform badly if the temperature is consistently outside the right range.
Ideal Temperature Range
As a guide, a practical target range for woodies is:
- 24°C to 30°C for general keeping
- 26°C to 30°C if you want stronger breeding performance
In this range, woodies tend to stay active, feed more consistently, and perform well as feeder insects.
Stable warmth is usually more important than chasing one exact number.
What Happens If Woodies Get Too Cold
When temperatures start dropping, woodies usually slow down before they die off. This makes cold-related issues easy to miss at first.
- they move less
- they eat less
- growth slows down
- breeding may stop entirely
Prolonged exposure to cool temperatures weakens the colony over time, especially if food intake also drops.
If your woodies seem sluggish or stop multiplying, temperature is one of the first things to check.
What Happens If Woodies Get Too Hot
Excessive heat creates a different set of problems. Woodies can handle warmth, but hot and stuffy conditions raise stress quickly.
- dehydration risk increases
- waste breaks down faster
- smell becomes stronger
- mould and bacteria risk if ventilation is poor
- die-off risk increases if ventilation is poor
Heat becomes especially dangerous when paired with too much moisture or stale air.
Warm is good. Overheated and poorly ventilated is not.
How Temperature Affects Breeding
If you are trying to breed woodies, temperature becomes even more important. Breeding performance usually improves in the warmer part of their ideal range.
In practical terms:
- warmer stable conditions improve breeding activity
- cooler conditions slow growth and breeding
- cold spells can stop breeding completely
This is why many keepers think their colony “isn’t breeding” when the real issue is simply that conditions are too cool.

Do You Need to Heat Woodies in Australia
That depends heavily on where you live and what you want from the colony.
Warmer Parts of Australia
In areas like much of Queensland and some northern parts of New South Wales, woodies may not need extra heating during warmer months.
In these locations, they may stay alive through winter without much help, but breeding can still slow if room temperatures fall too far.
Cooler Parts of Australia
In cooler regions such as Victoria, Tasmania, South Australia, and colder inland areas, heating is often needed, at least over winter, if you want consistent breeding or strong activity.
Survival and breeding are two different things. Woodies might stay alive in cooler conditions, but that does not mean they will perform well.
Best Ways to Maintain Temperature
You do not need a complicated setup..
Heat Mats
A heat mat placed under one side or along the side of the tub is one of the most common options. This gives the colony access to a warmer area without overheating the whole enclosure.
Warm Indoor Placement
Keeping the colony in a warm room, cupboard, or reptile room often works well if your house temperatures are already fairly stable.
Avoiding Temperature Swings
Large day-night swings can stress the colony even if the average temperature seems acceptable.
A slightly lower but stable setup usually performs better than a setup that swings sharply from warm to cold.
Common Mistakes to Avoid
- assuming room temperature is always enough
- allowing the tub to get hot without enough airflow
- using heat but not checking actual temperatures

Considering Dubia Roaches Instead
If you want a bigger feeder insect that is just as easy to manage, dubia roaches are a great option.
Dubia roaches are slower, easier to contain, and generally more forgiving for many keepers.

Final Thoughts
Woodies do best when temperatures are warm, stable, and paired with good airflow. If temperatures are too low, they slow down and stop breeding. If temperatures are too high, stress and dehydration become the bigger issue.
Getting the temperature right is one of the easiest ways to improve survival, activity, and colony performance.
