Bringing a tarantula into your home is an exciting prospect, but it’s crucial to be well-informed before you take the plunge. These fascinating creatures require specific care to thrive, and understanding their needs will ensure a healthy and rewarding experience for both you and your new pet. This guide provides essential tarantula care tips, focusing on key aspects to consider before you buy, helping you prepare for responsible tarantula ownership and providing your tarantula with the best possible life.
Tarantula Housing Requirements
Creating the right habitat is paramount for your tarantula’s well-being. The enclosure should mimic their natural environment, providing security and the necessary conditions for survival. Several factors play a crucial role, so let’s explore these important aspects of tarantula housing.
Enclosure Size
The enclosure size depends on the tarantula’s species and size. Generally, a terrarium that is twice as wide as the tarantula’s leg span and the same for depth is a good starting point. Juvenile tarantulas can start in smaller containers, gradually moving to larger ones as they grow. Providing too much space can make it difficult for the tarantula to find food, while insufficient space can restrict movement and cause stress. Always consider the species’ adult size when choosing an enclosure. A well-ventilated enclosure is also essential to prevent the buildup of harmful moisture.
Substrate Selection

Substrate is the bedding material that lines the bottom of the enclosure. The right substrate helps maintain humidity, provides a burrowing medium, and offers a sense of security for your tarantula. Popular choices include coconut fiber (coco coir), peat moss, and a mixture of both. Avoid substrates with sharp edges or those that can be easily ingested. The substrate should be deep enough to allow burrowing species to create their homes. The substrate should always be kept slightly moist, but not soaking wet. Ensure that the substrate is replaced regularly to prevent the growth of mold and bacteria. Choose a substrate that suits your tarantula’s specific species’ needs.
Temperature and Humidity Control
Tarantulas are ectothermic, meaning they rely on external sources to regulate their body temperature. Maintaining the correct temperature and humidity levels is crucial for their health and molting process. Research the specific temperature and humidity requirements for your tarantula species. Use a thermometer and hygrometer to monitor the enclosure’s conditions. A heat mat can be used on the side of the enclosure, but ensure it doesn’t dry out the substrate too quickly. Misting the enclosure with dechlorinated water can help maintain the proper humidity level. Proper ventilation is also key to preventing the build-up of excessive humidity, which can be harmful. Consistent monitoring of these conditions is critical to the health of your pet.
Feeding Your Tarantula
Providing a proper diet is another fundamental aspect of tarantula care. Tarantulas are opportunistic predators, and their feeding habits vary depending on their species and age. Here are the key things to know about feeding your tarantula, ensuring a healthy diet.
Prey Selection

Tarantulas primarily eat insects. The most common choices are crickets, mealworms, and roaches. The size of the prey should be appropriate for the tarantula’s size; the general rule is to offer prey no larger than the tarantula’s body. Ensure that the insects you feed are gut-loaded (fed nutritious food for at least 24 hours before being offered to the tarantula). This enhances the nutritional value for your tarantula. Avoid feeding wild-caught insects, as they may carry parasites or pesticides. Variety in the diet can be beneficial. Offer a mix of different prey items to provide a range of nutrients. Remove uneaten prey within 24 hours to prevent stress on the tarantula.
Feeding Frequency
The feeding frequency depends on the tarantula’s age and size. Spiderlings and juveniles need to be fed more often, typically 2-3 times a week. Adult tarantulas can be fed once a week or even less frequently, depending on their appetite. Overfeeding can lead to health problems. Monitor your tarantula’s abdomen; if it appears excessively plump, reduce the frequency of feeding. When the tarantula is approaching a molt, it may refuse food, which is a natural behavior. Do not offer food during this period. Always have fresh, clean water available.
Watering Your Tarantula
Tarantulas need a constant source of fresh water. The water should be provided in a shallow dish to prevent the tarantula from drowning. Use a water dish appropriate for the size of the tarantula, making sure it’s easily accessible. Change the water frequently, at least every other day, to prevent the growth of bacteria. For smaller tarantulas, use a cotton ball soaked in water, replacing it daily. In addition to the water dish, you can also mist the enclosure to maintain humidity levels, particularly for species that require higher humidity.
Tarantula Handling & Safety

Handling tarantulas can be a controversial topic. While some species are more docile than others, it’s important to exercise caution and understand the risks involved. Safety should always be your primary concern when interacting with your pet tarantula.
Handling Risks
Tarantulas can be easily injured if dropped. Handling should be kept to a minimum, only when necessary, such as enclosure maintenance or relocation. Even docile species can bite if they feel threatened. Bites can be painful and can cause localized reactions. Avoid handling after feeding or during molting, as they are more vulnerable then. Wash your hands thoroughly before and after handling the tarantula. Always handle tarantulas close to the ground or a soft surface to minimize the risk of injury if the tarantula falls. Handle with caution and respect.
Venom Toxicity
While tarantula venom is generally not lethal to humans, it can cause discomfort. The effects of a bite vary depending on the species, but can include pain, swelling, redness, and muscle cramps. Allergic reactions are rare but possible, and medical attention should be sought if you experience severe symptoms. If bitten, remain calm, wash the area with soap and water, and monitor for any adverse reactions. Some species possess urticating hairs on their abdomens, which can cause skin irritation if they come into contact with human skin. Avoid contact with the abdomen.
Tarantula Molting

Molting is a natural process where tarantulas shed their exoskeletons to grow. It’s a crucial part of their life cycle, and understanding the process will help you care for your tarantula effectively. Knowing the signs and appropriate care can help you support the process and ensure your pet’s health.
Signs of Molting
Before a molt, tarantulas may exhibit several signs. They may become less active and spend more time in their burrow or hiding place. The abdomen may appear dark or shiny. The tarantula may refuse food for several weeks before molting. You might also notice the abdomen and legs becoming more translucent. The tarantula may start to construct a web mat in preparation for the molt. It is important to avoid disturbing the tarantula during this period, as it is very vulnerable.
Post-Molting Care
After molting, the tarantula’s exoskeleton is soft. It may take several days or even weeks for the exoskeleton to harden. Do not feed the tarantula immediately after molting; wait a few days to allow the fangs to harden. Provide water. The tarantula will be very vulnerable during this time. Avoid handling or disturbing it. Ensure the enclosure conditions are correct to facilitate the hardening process. Be patient and do not panic; molting is a natural and essential process for tarantulas. Remove the old exoskeleton from the enclosure, if desired, once it has dried.
Tarantula Health and Diseases

Tarantulas are generally hardy creatures, but they can still be susceptible to certain health issues. Being aware of potential problems and knowing how to address them will help you provide the best care for your pet and ensure its longevity.
Common Health Issues
Some common health issues include mites, fungal infections, and injuries. Mites can be introduced through substrate or prey. Check your tarantula regularly for mites, and if you find them, consult with a veterinarian experienced in exotic pets. Fungal infections can occur if the enclosure is too humid or poorly ventilated. Injuries can result from falls or from attacking prey. Ensure proper handling and provide a safe environment to prevent these issues. If you suspect your tarantula is sick or injured, seek advice from a veterinarian.
Preventive Care
Preventive care is essential for maintaining your tarantula’s health. Maintain proper enclosure conditions, including temperature, humidity, and cleanliness. Provide a balanced diet and avoid overfeeding. Quarantine new tarantulas before introducing them to your existing collection to prevent the spread of diseases. Always wash your hands before and after handling your tarantula or handling its enclosure. Regularly inspect your tarantula for any signs of illness or injury. If you notice any abnormalities, consult with a veterinarian experienced in treating exotic pets. A proactive approach to care will help ensure the health and well-being of your tarantula.
Caring for a tarantula can be a rewarding experience. By following these tips, you can create a safe, enriching environment for your pet, and ensure a healthy and fulfilling life. Remember to research your tarantula species, and always prioritize their well-being. Enjoy your fascinating arachnid companion!
