Benefits of having a spider terrarium

When it comes to unique and fascinating pets, spiders are often overlooked. However, keeping a spider terrarium can offer numerous benefits that make them a worthwhile addition to any home. In this article, we will explore the advantages of having a spider terrarium, how to choose the right spider species, setting up the terrarium, caring for your spiders, common mistakes to avoid, and dealing with potential risks and concerns.

Natural pest control

One of the greatest benefits of having a spider terrarium is the natural pest control they provide. Spiders are skilled hunters and feed on insects such as flies, mosquitoes, and even small pests like cockroaches. By keeping spiders in your home, you can reduce the need for chemical pesticides and enjoy a pest-free environment.

Not only do spiders help control pests, but they also play a crucial role in maintaining the balance of ecosystems. They are an essential part of the food chain, preying on insects that can cause damage to crops and gardens. By creating a spider terrarium, you are contributing to the preservation of biodiversity and promoting a healthier environment.

Low maintenance

Contrary to popular belief, spiders are relatively low-maintenance pets. They require minimal care compared to other pets, making them an ideal choice for busy individuals or those who prefer low-maintenance pets. Spider terrariums do not require daily feeding, and spiders can survive for extended periods without food.

Additionally, spiders do not need frequent cleaning or grooming. They are self-sufficient creatures that take care of their own hygiene. As long as you provide them with a suitable habitat and the necessary resources, they will thrive with minimal intervention.

Educational tool

A spider terrarium can serve as an excellent educational tool, especially for children. Observing spiders in their natural habitat can help foster an appreciation for nature and the intricate web of life. It provides an opportunity to learn about different spider species, their behaviors, and their role in the ecosystem.

By setting up a spider terrarium, you can create a hands-on learning experience. Children can observe spiders building webs, catching prey, and molting. This firsthand experience can spark curiosity and encourage further exploration of the natural world.

Choosing the right spider species

Choosing the right spider species

When it comes to choosing the right spider species for your terrarium, it is essential to conduct thorough research. Different spider species have varying care requirements, temperaments, and levels of venomousness. It is crucial to select a spider species that aligns with your experience level and preferences.

Researching spider species

Before deciding on a spider species, I recommend researching their natural habitat, diet, and behavior. Understanding these factors will help you create a suitable environment and provide the necessary care for your spiders. Online resources, books, and reputable pet stores can provide valuable information on different spider species.

Consider factors such as the spider’s size, venom potency, and activity level. Some popular spider species for terrariums include the Chilean Rose Hair Tarantula, Mexican Red Knee Tarantula, and Jumping Spider. Each species has its own unique characteristics and care requirements, so choose one that matches your interests and comfort level.

Considerations for beginners

If you are a beginner in the world of spider keeping, it is advisable to start with a species that is known for its docile nature and ease of care. The Chilean Rose Hair Tarantula, for example, is a popular choice for beginners due to its calm temperament and relatively low maintenance requirements.

It is also important to consider the availability of food for your chosen spider species. Some spiders have specific dietary needs, while others are more adaptable. Ensure that you can provide a suitable diet for your spiders before bringing them home.

Setting up your spider terrarium

Setting up your spider terrarium

Creating the perfect environment for your spiders is crucial for their well-being. Here are some key considerations when setting up your spider terrarium:

Choosing the right enclosure

The first step in setting up your spider terrarium is selecting an appropriate enclosure. The enclosure should be escape-proof and provide adequate ventilation. Glass or plastic tanks with secure lids are commonly used for spider terrariums. Ensure that the lid has small ventilation holes to maintain proper airflow.

Consider the size of the enclosure based on the spider species you choose. Spiders require enough space to move around comfortably, but a terrarium that is too large may make it difficult for them to catch prey.

Creating a suitable habitat

Inside the terrarium, create a suitable habitat that mimics the spider’s natural environment. Start by adding a layer of substrate, such as coconut fiber or peat moss, to the bottom of the enclosure. This substrate will provide a comfortable surface for the spider to walk on and burrow into.

Next, add appropriate decorations such as rocks, branches, or artificial plants. These decorations not only enhance the aesthetic appeal of the terrarium but also provide hiding spots and climbing opportunities for the spiders.

Providing hiding spots

Spiders are nocturnal creatures that prefer dark and secluded hiding spots during the day. It is essential to provide hiding spots within the terrarium to ensure the well-being of your spiders. This can be achieved by placing small caves or hollow logs in the enclosure.

Additionally, consider adding artificial or live plants that provide cover and create a more natural environment. These hiding spots will help reduce stress and promote natural behaviors in your spiders.

Feeding and caring for your spiders

Feeding and caring for your spiders

Feeding and caring for your spiders properly is crucial for their health and well-being. Here are some important factors to consider:

Understanding spider diets

Spiders are carnivorous creatures that primarily feed on insects. The specific diet of your spider species should be thoroughly researched to ensure proper nutrition. Some spiders prefer live prey, while others can be fed pre-killed insects. It is important to provide a varied diet to ensure a balanced nutritional intake.

When feeding live prey, ensure that the prey is an appropriate size for your spider. Feeding prey that is too large can be dangerous for the spider, while prey that is too small may not provide sufficient nutrition.

Feeding schedule and portion sizes

Establishing a feeding schedule is important for maintaining the health of your spiders. Most spiders can be fed once or twice a week, while others may require more frequent feedings. Observe your spiders’ feeding habits and adjust the schedule accordingly.

When it comes to portion sizes, it is generally recommended to feed spiders prey that is approximately the same size as their body or slightly smaller. Overfeeding can lead to obesity and other health issues, while underfeeding can result in malnutrition.

Watering and humidity levels

While spiders obtain most of their hydration from their prey, it is still important to provide a water source within the terrarium. Place a shallow dish of water in the enclosure, ensuring that it is easily accessible for the spiders. Avoid using deep dishes that may pose a drowning risk.

Additionally, maintaining appropriate humidity levels is crucial for certain spider species. Research the specific humidity requirements of your chosen spider species and provide a suitable environment by misting the enclosure or using a humidifier if necessary.

Common mistakes to avoid

Common mistakes to avoid

When keeping a spider terrarium, it is important to avoid common mistakes that can negatively impact the health and well-being of your spiders. Here are some mistakes to watch out for:

Overcrowding the terrarium

It can be tempting to add multiple spiders to your terrarium, but overcrowding can lead to stress, aggression, and competition for resources. Ensure that the enclosure is spacious enough to accommodate the spider species you choose, allowing them to establish their own territories.

Using incorrect substrate

The substrate used in the terrarium plays a crucial role in maintaining the proper humidity levels and providing a suitable surface for the spiders. Using the wrong substrate can lead to issues such as mold growth, excessive moisture, or inadequate burrowing opportunities. Research the specific substrate requirements for your spider species and choose accordingly.

Not providing enough ventilation

Proper ventilation is essential for maintaining air quality and preventing the buildup of excess moisture within the terrarium. Inadequate ventilation can lead to respiratory issues and mold growth. Ensure that the enclosure has small ventilation holes or a mesh lid to allow for proper airflow.

Dealing with potential risks and concerns

Dealing with potential risks and concerns

While keeping a spider terrarium can be a rewarding experience, it is important to be aware of potential risks and concerns. Here are some key considerations:

Handling venomous spiders

Some spider species are venomous and can pose a risk to humans. It is crucial to exercise caution when handling venomous spiders or avoid handling them altogether. If you choose to keep venomous spiders, ensure that the enclosure is secure and that you have the necessary knowledge and experience to handle them safely.

Preventing escapes

Spiders are skilled escape artists, and it is important to take precautions to prevent them from escaping their terrarium. Ensure that the enclosure has a secure lid with no gaps or openings. Regularly inspect the enclosure for any signs of wear or damage that could potentially allow spiders to escape.

Addressing allergies and phobias

It is important to consider any allergies or phobias that you or your household members may have before keeping a spider terrarium. Some individuals may have allergic reactions to spider bites or may experience severe anxiety or fear around spiders. It is crucial to prioritize the safety and well-being of everyone involved.



A spider terrarium can offer numerous benefits, including natural pest control, low maintenance, and educational opportunities. By choosing the right spider species, setting up a suitable terrarium, and providing proper care, you can enjoy the fascinating world of spiders as pets. Remember to avoid common mistakes, address potential risks, and always prioritize the well-being of your spiders. With proper knowledge and care, a spider terrarium can be a captivating addition to your home.


  • Can you keep spiders in a terrarium?

    Large spiders do well in the inexpensive plastic terrariums available from pet stores. Smaller ones can be kept in jars or plastic containers if air holes are drilled into the lid or sides. Be sure the holes are small enough to prevent escape. Potting soil makes good cover for the cage bottom.

  • What do you put in a spider enclosure?

    In addition to food, you need to provide fresh water for your spider. You can use a plastic bottle cap as a water bowl if you have a small spider in a small cage. If you have room, give your spider a small bowl of water. Spiders will also drink the water off of damp webbing.

  • What terrariums are best for jumping spiders?

    Which terrarium is suitable for keeping jumping spiders? Terrariums with a greater height than length and width are particularly suitable as accommodation. Terrariums or containers with 10 × 17 × 21 cm to 20 × 20 × 30 cm are ideal. However, you can also keep the animals in tins of similar dimensions.

  • How big do spider enclosures need to be?

    Spiders and most insects or critters need a minimum enclosure dimension of two to three times their body length, often measured diagonally. Learn how to measure and choose the right enclosure size & type as well as style with this guide.
