Tarantula Care Guide for Beginners: Housing, Feeding, Handling, and Common Mistakes

Not every tarantula is ideal for a first pet. In general, many New World terrestrial species are considered easier for beginners because they tend to be slower-moving and are more often managed as low-handling display animals. Cornell specifically highlights the Honduran curly hair as a fairly active, inexpensive species that is not particularly aggressive.

Ask for the scientific name before you bring a tarantula home. Common names are inconsistent, and care needs can change a lot between terrestrial, fossorial, and arboreal species. Also ask whether the spider is a sling, juvenile, adult female, or mature male. Cornell notes that mature males often have much shorter remaining lifespans after maturity, so that affects expectations and long-term planning.

Choose an escape-proof enclosure with good ventilation and enough floor space for the species' lifestyle. Terrestrial tarantulas usually need more horizontal space than height because falls can be dangerous, especially for heavier-bodied spiders. Arboreal species need more vertical climbing space and secure anchor points.

For substrate, many keepers use clean coco fiber, topsoil blends without fertilizers, or other species-appropriate burrowing material. The substrate should be deep enough for digging if your species burrows. Add at least one hide and a shallow water dish. Cornell describes tarantulas as needing warm, moist living areas in many common pet setups, but exact humidity should be based on the species rather than guessed.

Avoid sharp decor, unstable rocks, and excessive enclosure height for terrestrial species. A short fall can rupture the abdomen. Keep the enclosure in a quiet area away from direct sun, drafts, and heat vents. If you use room heating or supplemental heat, monitor temperatures carefully and avoid overheating the enclosure.

Most pet tarantulas do well when kept within a stable species-appropriate range rather than exposed to big day-to-night swings. Use a thermometer and hygrometer so you are measuring conditions instead of estimating them. PetMD care guidance for exotic habitats emphasizes checking humidity regularly with a hygrometer, and that principle applies well to tarantula setups too.

Humidity mistakes are common. Too-dry conditions can contribute to dehydration and difficult molts in moisture-dependent species, while chronically wet substrate can encourage mold, mites, and stress in species from drier habitats. For many beginners, the safest routine is to keep one side of the enclosure slightly more humid, keep the water dish clean and full, and adjust based on the species and how the tarantula actually uses the enclosure.

Tarantulas eat live invertebrate prey such as crickets, roaches, or mealworms sized appropriately for the spider. Cornell notes that pet tarantulas may be fed once every one to three weeks, though younger spiders usually eat more often than adults. A sling may need small prey several times weekly, while a settled adult may eat every 7 to 14 days or even less often depending on species, size, and molt cycle.

Offer prey that is no larger than the tarantula can safely subdue. Remove uneaten prey within about 24 hours, and sooner if your tarantula is in premolt. Cornell specifically warns about cricket predation, meaning feeder insects can injure a vulnerable tarantula, especially during a molt. Fresh water should be available at all times in a shallow dish sized so the spider can drink safely.

Handling is optional, and for many tarantulas it is best avoided. Cornell advises against cuddling or routine handling and warns that stressed tarantulas may flick urticating hairs. Those hairs can cause itchy skin and inflamed membranes, and Cornell reports that eye exposure has, in some cases, required surgical removal. Merck also states that the primary concern with tarantulas is often the fine defensive hairs on the abdomen.

If handling is ever discussed, keep it minimal and low to the ground, and never over hard flooring. A startled tarantula can bolt, jump, or fall. Wash your hands after contact with the spider, molt skins, substrate, or enclosure items. Keep the enclosure away from curious children and other pets, and ask your vet what to do if anyone in the home has an eye exposure, bite, or allergy concern.

Molting is when a tarantula sheds its exoskeleton to grow. Before a molt, many tarantulas eat less, become less active, darken in color, or spend more time hidden. Cornell's spider resources note that mortality can occur during molting, especially in young spiders or when husbandry is off, so this is a period to disturb the enclosure as little as possible.

Do not handle a tarantula during premolt or immediately after a molt. Do not leave feeder insects in the enclosure. After molting, the new exoskeleton and fangs need time to harden before feeding resumes. If your tarantula is stuck in a molt, has curled legs, cannot right itself, or appears injured, contact your vet promptly for guidance.

Spot-clean the enclosure by removing prey remains, shed skins, and obvious waste. Refresh the water dish often and clean it regularly. Full substrate changes are usually done less often than with many mammals, but the enclosure should still be kept dry where appropriate, free of mold, and secure.

When you schedule a wellness visit with your vet, bring photos of the enclosure and your temperature and humidity readings. PetMD exotic care sheets commonly recommend bringing habitat photos for veterinary review, and that is especially helpful for tarantulas because husbandry errors are a common cause of problems.

One common mistake is choosing a species based only on appearance. Another is using too much enclosure height for a terrestrial spider, which raises the risk of a dangerous fall. Beginners also often over-handle, overfeed, or panic during a normal fasting period before a molt.

Other frequent problems include keeping the substrate too wet or too dry, leaving live crickets in with a molting spider, using an insecure lid, and buying a mature male without realizing his lifespan may be limited. Cornell also notes that pet-store advice may be incomplete or species-inaccurate, so it helps to confirm care details with your vet and a reliable species-specific reference before making changes.

Contact your vet if your tarantula has an injured or leaking abdomen, repeated falls, trouble walking, persistent curled-under legs, a bad molt, visible parasites, or a sudden major behavior change that does not fit a normal premolt pattern. Also call if your tarantula has gone off food for an unusually long time and is losing condition, or if there has been a bite or urticating-hair exposure to a person or another pet.

Exotic-animal veterinarians can help assess whether the problem is medical, husbandry-related, or both. Because tarantulas are sensitive to environmental errors, your vet may want details about prey type, feeding frequency, enclosure size, substrate depth, humidity, temperature, and recent molts.
