Humidity

In addition to heat, crickets prefer stable humidity around 60-75%. You can purchase inexpensive humidity meters from pet stores that sell reptiles. A Conventional breeding system (refer to How to Breed Crickets page) will have a lower humidity than a substrate breeding system due to the absence of a wet substrate. A substrate system will generally have sufficient moisture where the soil is kept moist.

Humidity is important to prevent dehydration and to facilitate moulting. Once a cricket has lost its old protective exoskeleton, it is prone to dehydration. Where crickets are dying during their moult, humidity should be increased.

Too much humidity can create harmful pathogens such as fungi, bacteria, mites. Condensation on the walls of the container is a sign of too much humidity or poor ventilation. Your egg/apple cartons will also quickly become floppy/soggy, food becomes mouldy or ferments which results in bad smells.

Humidity generally increases as moisture availability and ambient temperatures increases, and decreases with reduced water availability and lower ambient temperatures. Humidity can be increased in the following ways:

  • Partially block off the ventilation ports with tape.
  • Cover the whole ventilation port with a thin towel
  • Add free available water sources source such as a bowl with pebbles, in it so crickets don’t drown or a small substrate area which is misted every few days. The larger the surface area, the more humidity will evaporate.
  • Provide daily wet foods to your crickets
  • Mist and spray the sides of the container every 2-3 days.

Humidity can be decreased in the following ways:

  • Increase ventilation
  • Remove unnecessary water sources such as substrate, additional water bowls etc.
  • Is the amount of wet foods provided excessive?
