Best Temperature for Live Crickets
Temperature is one of the most important factors when keeping live crickets. Even small changes can affect their survival rate, activity levels, and how quickly they grow.
If your crickets are dying quickly or becoming inactive, it's important to look at temperature.
Quick answer: The ideal temperature for live crickets is between 24°C and 30°C, with 25–28°C being optimal for most setups.
Why Temperature Matters for Crickets
Crickets are cold-blooded insects, meaning their body functions are directly influenced by the temperature around them.
Temperature affects:
- metabolism and energy use
- growth speed
- feeding behaviour
- lifespan
- breeding activity
Keeping crickets outside their ideal temperature range can quickly lead to stress and increased mortality.
Ideal Temperature Range
For most reptile keepers, maintaining a consistent temperature is more important than hitting an exact number.
- Optimal range: 26–28°C
- Acceptable range: 20–30°C
- Below 20°C: metabolism slows significantly
- Above 32°C: stress and die-offs increase
Staying within the optimal range helps keep crickets active, feeding, and growing at a steady rate.
Sudden temperature changes can be just as harmful as incorrect temperatures.
What Happens if Crickets Get Too Cold
When temperatures drop below their ideal range, crickets slow down dramatically.
- reduced movement and activity
- slower growth
- lower feeding response
- increased vulnerability to death over time
In cooler climates or during winter, this is one of the most common reasons crickets stop thriving.
Extended exposure to cold conditions can lead to gradual die-offs.
What Happens if Crickets Get Too Hot
High temperatures can be just as dangerous, especially when combined with poor ventilation.
- increased stress levels
- faster dehydration
- rapid die-offs
- stronger smell due to waste breakdown
Overheating often happens when containers are placed in direct sunlight, near strong heat sources, or here in Australia, just at room temp! If you're in a warmer climate, it's essential to keep an eye on your temperatures.
Once temperatures exceed safe limits, cricket populations can crash very quickly. They're quite sensitive insects on a good day.
How Temperature Affects Growth
Temperature plays a major role in how quickly crickets grow through their life stages.
- warmer temperatures increase growth speed
- cooler temperatures slow development
However, pushing temperatures too high to speed up growth often leads to higher mortality rates.

Maintaining a stable temperature is the best way to achieve consistent results.
How to Control Temperature
There are several simple ways to maintain a stable environment for your crickets:
- keep them in a temperature-controlled room
- use a heat mat under one side of the container
- avoid direct sunlight
- monitor with a thermometer
Providing a slight temperature gradient allows crickets to move to more comfortable areas. This is done by placing a heat mat under one side of the container.
This can help reduce stress and improve survival rates.
Crickets vs Dubia Roaches Temperature Tolerance
One of the main challenges with crickets is how sensitive they are to temperature changes.
Dubia roaches, on the other hand, are generally more tolerant of fluctuations and tend to survive better across a wider range of conditions.
This and their longer lifespan makes them a more stable feeder option for many reptile keepers.
Choosing the right feeder can make a big difference in ease of care and consistency.
Common Temperature Mistakes
- keeping crickets in cold garages or outdoor areas
- placing containers in direct sunlight or by a window
- not monitoring temperature changes
- using heat without ventilation
Avoiding these mistakes can significantly improve cricket survival rates.
