Enclosure Size and Type

The size and type of enclosure depend on the size of the tarantula. For smaller slings, a clear plastic container with good ventilation is suitable. As the tarantula grows, you’ll need to upgrade the enclosure. A general guideline is that the enclosure should be at least three times the tarantula’s leg span in width. Height is less critical for terrestrial species but should be sufficient to accommodate substrate depth and any decorative elements. Glass terrariums with secure lids are also a good option, providing excellent visibility and security. Ensure the enclosure has adequate ventilation to prevent the buildup of humidity and the growth of mold. Avoid enclosures made of materials that are difficult to clean or that could potentially harm the tarantula.
Substrate and Decor
The substrate provides a suitable environment for the tarantula to burrow and feel secure. Coconut fiber is a popular choice due to its excellent moisture retention, natural look, and suitability for burrowing. Other options include peat moss and vermiculite, which can also maintain good humidity levels. The substrate should be deep enough to allow the tarantula to burrow if it chooses. Decor such as cork bark, artificial plants, and hiding places provides enrichment and a sense of security. Ensure that any decor is clean and free of sharp edges or potential hazards. Arrange the decor to provide the tarantula with multiple hiding spots and a varied environment. Avoid using items that might decompose and attract unwanted pests, and regularly check the enclosure for mold or other signs of contamination.
Temperature and Humidity
Terrestrial tarantulas require specific temperature and humidity levels to thrive. Maintaining the right temperature is critical to support their metabolism and overall well-being. The ideal temperature range for most terrestrial tarantulas is between 75°F and 85°F (24°C and 29°C). Use a heat mat on the side of the enclosure or a low-wattage heat lamp to maintain this temperature. Regularly monitor the temperature using a thermometer. Humidity is also an essential factor, as it helps with moulting. The required humidity level varies depending on the species, but generally, between 60% and 70% is ideal for most terrestrial species. Regularly misting the enclosure with dechlorinated water can help to maintain humidity. A hygrometer is crucial to monitor the humidity accurately. Adjust the ventilation in the enclosure to maintain the correct humidity levels, as excessive ventilation can dry out the enclosure while insufficient ventilation can lead to mold growth.

What to Feed Tarantulas
The ideal diet for a terrestrial tarantula primarily consists of insects. Crickets, mealworms, and dubia roaches are all popular and readily available options. Choose insects that are appropriately sized for the tarantula; the prey should generally be no larger than the tarantula’s body size. Pre-killed insects are an option for tarantulas, especially slings, and reduce the risk of injury to the tarantula. Ensure that the insects you feed are gut-loaded, which means they are fed nutritious food before being offered to the tarantula. This helps provide the tarantula with a more complete diet. Avoid feeding wild-caught insects, as they may carry parasites or pesticides. Always keep a supply of fresh water available, either in a shallow dish or by misting the enclosure. The water is crucial for hydration.
Feeding Frequency

Feeding frequency depends on the tarantula’s age and growth rate. Young tarantulas (slings) require more frequent feeding, typically two to three times per week. Adult tarantulas can be fed less frequently, usually once every one to two weeks. Observe your tarantula’s feeding habits to determine the ideal schedule. A tarantula that is ready to moult will often refuse food. Remove any uneaten prey within 24 hours to prevent the insects from stressing the tarantula or potentially harming it. Adjust the feeding frequency based on your tarantula’s appetite, growth rate, and overall health. Avoid overfeeding, which can lead to health issues. A healthy tarantula should have a plump abdomen, but not excessively so.
Water and Hydration
Clean, fresh water is essential for your tarantula’s survival. Provide water at all times, either in a shallow dish or by misting the enclosure. The water dish should be shallow enough to prevent the tarantula from drowning. For slings, use a bottle cap or a small, shallow container. Mist the enclosure with dechlorinated water once or twice a week to maintain humidity levels. Avoid using tap water, as it can contain chlorine and other chemicals harmful to tarantulas. Regularly check the water source to ensure it remains clean and free from debris. Replace the water frequently, typically every few days. Proper hydration is crucial, especially during moulting. A well-hydrated tarantula is more likely to have a successful moult. Always monitor your tarantula for signs of dehydration, such as a shrunken abdomen.
Handling and Safety
Handling a tarantula is a personal decision that requires careful consideration. Some tarantulas are docile and tolerate handling, while others are more defensive and may bite or exhibit defensive behaviors. Always prioritize your safety and the tarantula’s well-being. Avoid handling if you are unsure of your tarantula’s temperament or if you are new to tarantula care. Always be prepared to handle the situation calmly and respectfully. Understanding how to handle a tarantula properly, along with knowing its stress signals, is crucial to prevent injury to yourself and the spider.
