Can Crickets And Mealworms Live Together? Can They Cohexist?

Insects have become increasingly popular as pets in recent years, and two of the most commonly kept insects are crickets and mealworms. These creatures are fascinating to observe and relatively easy to care for, making them an attractive option for those looking for a low-maintenance pet. However, if you’re considering keeping crickets and mealworms together, you may be wondering if it’s possible for these two species to coexist in the same habitat.

In this article, we’ll explore the differences between crickets and mealworms, their compatibility, and best practices for keeping them together. By understanding the unique characteristics of these two species and taking the necessary precautions, you can create a safe and enriching environment for both crickets and mealworms.

Differences between crickets and mealworms

Before we can determine whether crickets and mealworms can live together, it’s important to understand the differences between these two species. Here are some of the key differences:

Physical differences

  • Crickets are larger and more active than mealworms.
  • Mealworms have a distinct body structure with a head, thorax, and abdomen, while crickets have a more streamlined body with distinct legs and antennae.

Behavioral differences

  • Crickets are highly active and love to jump, while mealworms are more sedentary and tend to burrow.
  • Mealworms are nocturnal and prefer to be active at night, while crickets are diurnal and active during the day.

Dietary differences

  • Crickets are omnivores and will eat a variety of foods, including fruits, vegetables, and other insects.
  • Mealworms are detritivores and will eat decaying plant and animal matter.

Compatibility of crickets and mealworms

Given their differences, can crickets and mealworms live together in the same habitat? The answer is yes, they can, but there are some potential risks to consider.

Potential risks

  • Overcrowding: Crickets are more aggressive than mealworms and may harm them if they are overcrowded. It’s important to provide enough space for both species to move around comfortably.
  • Waste buildup: Mealworms produce waste that can accumulate and create a breeding ground for harmful bacteria. Regular cleaning and waste removal are essential to prevent the spread of disease.
  • Disease spread: If one of the insects is carrying a disease, it could spread to the other. It’s important to monitor the insects closely for signs of illness or injury and separate them if necessary.


  • Enrichment: Crickets and mealworms can coexist without competing for the same food source, as they have different dietary requirements. Having both species in the same habitat can provide enrichment for both, as they will have different behaviors and activities that can be observed.
  • Compatibility: While crickets and mealworms have different activity levels and behaviors, they can still coexist in the same habitat. As long as their basic needs are met and they are not overcrowded, they should be able to live together without issue.

By being aware of the potential risks and taking steps to mitigate them, you can create a safe and enriching environment for both crickets and mealworms.

Best practices for keeping crickets and mealworms together

If you have decided to keep crickets and mealworms together, there are several best practices to follow to ensure their well-being and safety.

Habitat setup

  • Habitat size: Provide enough space for both species to move around comfortably. A general rule of thumb is to have a habitat that is at least three times the size of the number of insects you are keeping.
  • Substrate: Provide a substrate that is suitable for both crickets and mealworms. A mix of coconut fiber and vermiculite is a popular choice, as it provides a suitable environment for burrowing and moisture retention.
  • Hiding places: Provide hiding places and structures for both species, such as pieces of bark or egg cartons. This will allow them to retreat to a safe space if they feel stressed or threatened.
  • Lighting and temperature: Provide appropriate lighting and temperature for both species. Crickets require a warm and humid environment, while mealworms prefer cooler temperatures. A temperature range of 75-85°F (24-29°C) is suitable for crickets, while a temperature range of 70-80°F (21-27°C) is suitable for mealworms.


  • Provide a varied diet: Offer both crickets and mealworms a varied diet that meets their nutritional requirements. Crickets require a diet high in protein and calcium, while mealworms require a diet high in fat and fiber. You can offer commercial diets or fresh fruits and vegetables as supplements.
  • Separate feeding areas: Provide separate feeding areas for crickets and mealworms to prevent competition and reduce the risk of injury. You can use shallow dishes or containers for each species.


  • Regular cleaning: Regularly clean the habitat and remove waste to prevent the buildup of harmful bacteria.
  • Monitor for signs of illness or injury: Monitor the insects closely for signs of illness or injury, such as lethargy, loss of appetite, or deformities. If you notice any issues, separate the affected insect and seek veterinary care if necessary.


In conclusion, crickets and mealworms can live together in the same habitat with proper care and attention. While there are potential risks, such as overcrowding and disease spread, these can be mitigated by providing enough space, proper substrate, separate feeding areas, and regular cleaning.

By keeping crickets and mealworms together, you can provide enrichment for both species and observe their different behaviors and activities. Remember to provide appropriate lighting and temperature, a varied diet, and regular monitoring for signs of illness or injury.

Whether you’re keeping crickets and mealworms as pets or for breeding, following best practices will ensure their well-being and safety. With the right setup and care, you can create a thriving habitat for these fascinating insects to coexist in harmony.
