The Importance of Temperature and Humidity in Cricket Care

Crickets, like many other living organisms, thrive best under specific environmental conditions. Ensuring that they have the appropriate temperature and humidity levels not only guarantees their survival but also optimizes their growth and breeding capabilities. Let's delve into the essential ranges for both temperature and humidity, the consequences of deviations, and how to effectively maintain these conditions.

1. Optimal Temperature for Crickets

Ideal Range: The best temperature range for crickets, specifically the common house cricket (Acheta domesticus), lies between 75°F to 90°F (24°C to 32°C). Within this range, crickets remain active, eat well, grow at a healthy pace, and reproduce efficiently.

Effects of Deviation:

  • Too Cold (<75°F or 24°C): At temperatures below their ideal range, crickets become sluggish and less active. Their metabolism slows down, resulting in reduced feeding and growth rates. Extended exposure to colder temperatures can lead to dormancy or even death.

  • Too Hot (>90°F or 32°C): Exposing crickets to temperatures above their optimal range can lead to heat stress. This can cause increased water consumption, decreased activity, and, if prolonged, can lead to high mortality rates.

2. Optimal Humidity for Crickets

Ideal Range: The ideal humidity level for crickets ranges between 50% to 70%. Keeping the humidity within this range ensures that crickets remain hydrated and reduces the risks associated with both extremely dry and overly wet environments.

Effects of Deviation:

  • Too Dry (<50%): A dry environment can lead to dehydration in crickets. This affects their overall health, leading to reduced activity, difficulty in molting, and an increased risk of mortality.

  • Too Wet (>70%): Overly humid conditions can be a breeding ground for harmful bacteria, mold, and mites. This can lead to diseases spreading through the colony, resulting in significant losses. Additionally, excessive moisture can suffocate and drown crickets.

Maintaining Optimal Conditions

Temperature Maintenance:

  1. Heating Pads: Placing heating pads beneath the cricket container can provide consistent warmth. It's vital to monitor the temperature and adjust the heating pad's settings as required.

  2. Room Heaters: If the entire room housing the crickets needs warming, a room heater can be beneficial. Ensure it's equipped with a thermostat for accurate temperature regulation.

  3. Light Bulbs: Incandescent bulbs can be placed above the container, providing both heat and light. However, always ensure there's a buffer space to prevent overheating or direct contact.

Humidity Maintenance:

  1. Water Gel Crystals: Instead of open water bowls, which can drown crickets and increase humidity rapidly, use water gel crystals. They hydrate crickets without drastically altering humidity levels.

  2. Misting: Lightly misting the cricket enclosure can increase humidity. Be cautious, though — over-misting can lead to wet conditions, which are detrimental to crickets.

  3. Hygrometers: This tool measures humidity levels, allowing you to monitor and make necessary adjustments promptly.


The success of a cricket colony is significantly influenced by the environmental conditions they're subjected to. By understanding the optimal temperature and humidity levels and being equipped to maintain these conditions, cricket farmers and enthusiasts can ensure their colony remains healthy, active, and thriving. Whether you're raising crickets as feed for reptiles or for other purposes, diligent care in regulating temperature and humidity will result in a robust cricket population ready to chirp another day.
