Tarantula Care Cycle
Tarantula Care Checklist
| Enclosure: 2–3x legspan floor area | |
| Substrate: 3–4in coco fiber for burrowers | |
| Temperature: 68–78°F, no heat mats | |
| Feeding: 1–2 crickets/roaches weekly | |
| Water dish: shallow, always available | |
| Molt: Do NOT disturb, no feeding 5–7 days | |
| Humidity: species-appropriate level | |
| Handling: minimal, only calm spiders |
Tarantulas are among the lowest-maintenance exotic pets available -- they require no daily interaction, eat once a week or less, and live in enclosures that require minimal upkeep. They are fascinating to observe and, for most species, completely safe to keep. The primary care requirements are appropriate temperature and humidity, appropriately-sized enclosures that match the species' lifestyle, and correctly-sized prey items. This simplicity makes them genuinely beginner-accessible for people comfortable with spiders.
Choosing a Species: Temperament and Care Requirements
Beginner species are terrestrial, slow-growing, docile, and forgiving of minor husbandry errors. Best beginner tarantulas: Brachypelma hamorii (Mexican Red Knee -- slow, docile, stunning orange and black coloration), Grammostola pulchripes (Chaco Golden Knee -- extremely docile, fast growth), Grammostola pulchra (Brazilian Black -- docile, beautiful solid black coloration, slow growth), and Euathlus sp. (Pumpkin Patch -- tiny, manageable). Avoid as first spiders: Poecilotheria species (Old World, fast, and potentially medically significant venom), Pterinochilus species, and Haplopelma/Cyriopagopus species (aggressive).
Enclosure Requirements by Lifestyle Type
Terrestrial/burrowing species (most beginners): enclosure should have floor footprint 2 to 3 times the legspan with height equal to legspan -- tall enclosures create fall risk for slow, heavy-bodied tarantulas. Provide 3 to 4 inches of substrate for burrowing (coconut fiber, coir, or a sand/coir mix). A hide is helpful but many species will excavate their own. Arboreal species (Avicularia, Caribena): taller enclosures with cross-ventilation; these species construct silk retreats in the upper portions of the enclosure.
Temperature: most New World species thrive at room temperature (68 to 78 degrees F). No supplemental heating required in most homes. Avoid direct heat sources -- tarantulas have no thermosensor equivalent to tell them when they are too close to a heat source, and heat mats can cause dehydration or burns. Humidity: species-dependent. Arid species (Grammostola, Brachypelma) do well with one corner lightly dampened and the rest dry. Tropical species (Avicularia, Chromatopelma) need moderate humidity with good ventilation.
Feeding
Feed appropriately-sized prey -- the prey item should be approximately the same size as the tarantula's abdomen or slightly smaller. Juveniles eat crickets, mealworms, or dubia roaches; adults eat dubia roaches, crickets, or pre-killed pinky mice occasionally. Feed once weekly for juveniles, every 1 to 2 weeks for adults. Remove uneaten prey within 24 hours -- live crickets left in the enclosure during molting can injure or kill a molting tarantula.
Molting: The Critical Period
Tarantulas molt (shed their exoskeleton) to grow. Signs of pre-molt: reduced appetite or complete refusal to eat (can last weeks to months), darkening abdomen, sluggishness, flipping on the back (normal, not distress). During molt: do not disturb, do not add prey. Post-molt: the new exoskeleton is soft and the tarantula is vulnerable -- do not add prey for 1 to 2 weeks after molt (confirm the fangs have darkened before feeding again).
