What is an insect terrarium?
An insect terrarium is a specially designed enclosure that allows you to create a natural habitat for insects. It provides a controlled environment where you can observe and care for various insect species. Insect terrariums are popular among hobbyists, educators, and nature enthusiasts who want to study and appreciate the fascinating world of insects up close.

Choosing the right container for your insect terrarium

When it comes to selecting a container for your insect terrarium, there are a few factors to consider. The two main options are glass and plastic containers.

Glass or plastic?

Glass containers are often preferred for insect terrariums because they provide better visibility and are more aesthetically pleasing. They also tend to retain heat and humidity better than plastic containers. However, glass can be heavier and more fragile, so it’s important to handle it with care.

On the other hand, plastic containers are lightweight and durable, making them easier to handle and transport. They are also less likely to break if accidentally dropped. However, plastic may not provide the same level of insulation as glass, and visibility may be slightly compromised.

Ultimately, the choice between glass and plastic depends on your personal preferences and the specific needs of the insects you plan to keep.

Size and shape considerations

The size and shape of your insect terrarium will depend on the type and number of insects you wish to house. Some insects require more space to fly or climb, while others prefer smaller, more confined spaces. Research the specific needs of the insects you plan to keep to determine the appropriate size and shape of your terrarium.

It’s also important to consider the accessibility of the terrarium for cleaning and maintenance. Choose a container with a wide opening or removable lid to make it easier to reach inside and make adjustments as needed.

Creating the perfect habitat for your insects

To ensure the well-being of your insects, it’s crucial to create a suitable habitat within the terrarium. This involves providing the right substrate, maintaining optimal temperature and humidity levels, and incorporating appropriate lighting, plants, and decorations.


The substrate refers to the material that lines the bottom of the terrarium. It should mimic the natural environment of the insects you are keeping. For example, some insects prefer sandy substrates, while others thrive in moist soil or leaf litter. Research the specific substrate requirements of your chosen insect species and provide them with a suitable substrate to promote their well-being.

Temperature and humidity

Different insect species have varying temperature and humidity requirements. It’s important to research the ideal conditions for your chosen insects and provide them with a suitable environment. This may involve using a thermometer and hygrometer to monitor and regulate the temperature and humidity levels within the terrarium. Heating pads, heat lamps, or misting systems can be used to maintain the desired conditions.


Proper lighting is essential for the health and well-being of your insects. Some insects require direct sunlight, while others prefer diffused or artificial lighting. Research the lighting needs of your chosen insect species and provide them with the appropriate light source. Consider using full-spectrum bulbs or UVB lights to simulate natural sunlight.

Plants and decorations

Adding live plants and decorations to your insect terrarium can enhance the aesthetic appeal and provide a more natural environment for your insects. Choose plants that are safe for your insects and can thrive in the terrarium conditions. Decorations such as branches, rocks, and hiding spots can also create a more stimulating and enriching habitat for your insects.

When selecting insects for your terrarium, it’s important to research the specific needs and behaviors of different insect species.

Researching insect species

Take the time to learn about the specific requirements and behaviors of the insects you are interested in keeping. Consider factors such as diet, temperature and humidity preferences, lifespan, and compatibility with other species. This research will help you make informed decisions and create a suitable environment for your chosen insects.

Compatibility of different insect species

Some insect species are not compatible with others and may exhibit aggressive or predatory behaviors. It’s important to choose insect species that can coexist peacefully within the same terrarium. Research the compatibility of different species and avoid mixing insects that may harm or stress each other.

Feeding and caring for your insects

Proper feeding and care are essential for the health and longevity of your insects.

Understanding the dietary needs of your insects

Different insect species have specific dietary requirements. Some insects feed on plant matter, while others are carnivorous or omnivorous. Research the feeding habits of your chosen insects and provide them with a varied and balanced diet. This may include fresh fruits, vegetables, nectar, pollen, or live prey.

Providing water and hydration

Insects require access to water for drinking and maintaining proper hydration. Depending on the species, this can be provided through a shallow dish of water, misting the terrarium, or providing moisture-rich foods. It’s important to regularly monitor and replenish the water source to ensure your insects have an adequate supply.

Cleaning and maintaining the terrarium

Regular cleaning and maintenance of the terrarium are crucial for the health and well-being of your insects. Remove any waste, uneaten food, or dead insects promptly to prevent the buildup of harmful bacteria or pests. Clean the terrarium regularly using a mild soap or vinegar solution, ensuring that all surfaces are thoroughly rinsed and dried before reintroducing the insects.

Observing and enjoying your insect terrarium

One of the joys of having an insect terrarium is the opportunity to observe and learn from the behaviors of your insects.

Watching insect behavior

Spend time observing your insects and their interactions within the terrarium. Observe their feeding habits, mating behaviors, and any other interesting behaviors they exhibit. This firsthand observation can provide valuable insights into the lives of these fascinating creatures.

Documenting and learning from your observations

Keep a journal or record of your observations and any notable behaviors or changes you observe in your insects. This documentation can help you track their growth, health, and any patterns or trends that emerge over time. It can also serve as a valuable learning resource and contribute to the broader understanding of insect behavior.


Creating and maintaining an insect terrarium can be a rewarding and educational experience. By providing a suitable habitat, choosing the right insects, and caring for them properly, you can enjoy the beauty and wonder of the insect world up close.

Remember to always research the specific needs of your chosen insects and make adjustments as necessary to ensure their well-being. Happy terrarium keeping!


  • What insect can you put in a terrarium?

    Praying mantises, leaf insects, walking leaves, grasshoppers and beetles are very popular terrarium animals. Their demands on the terrariums vary considerably. Praying mantises do not need much space. Small terrariums with a 30 cm edge length are ideal.

  • How do you make a bug terrarium?

    To make a bug terrarium, start by covering the bottom of a glass or plastic container with sand or gravel. Next, add 2 to 4 inches of soil so your bugs have something to play in. You should also plant weeds or other plants in the container for the bugs to eat, along with sticks for them to hide under.

  • What insects are best for a bioactive terrarium?

    Bioactive bugs act as a “cleanup crew” in your terrarium. They feed on decaying plant matter and mold to help keep your terrarium fresh and recycle nutrients in the soil. The most common terrarium bugs are springtails and isopods. Both bugs are completely harmless to plants and humans.

  • What is the difference between a terrarium and a vivarium?

    Today, terrariums are used mostly by hobbyists who plant commercially propagated materials. Terrariums can be used as a naturalistic environment for keeping small reptiles and amphibians, much like an aquarium is used for keeping fish. This type of modified terrarium is called a “vivarium.”
