Caring for Lasiodora subcanens, a large terrestrial tarantula native to Brazil, requires specific attention to their natural environment, diet, and overall health. Here’s a guide to their care:
 
Habitat and Enclosure
    1.    Size:
Provide a terrarium of at least 30cm x 45cm x 30cm (12” x 18” x 12”) for adults. These tarantulas are large and need room to move.
    2.    Substrate:
Use 3–4 inches of a moisture-retaining substrate like coconut fiber, peat moss, or a soil mix. This species enjoys moderate humidity levels.
    3.    Humidity:
Maintain 60–80% humidity. Mist the enclosure lightly a few times a week but avoid over-soaking the substrate.
    4.    Temperature:
Keep the temperature between 24–28°C (75–82°F). A heat mat can be used if the room is cold, but avoid direct contact with the enclosure to prevent overheating.
    5.    Hides:
Provide a hide, such as a cork bark or half a coconut shell, to allow the tarantula to retreat and feel secure.
    6.    Water:
Include a shallow water dish and keep it clean. Ensure it’s not too deep to avoid drowning.
 
Diet
    1.    Food:
Feed a diet of crickets, roaches, mealworms, or superworms. Adult Lasiodora subcanens can also take the occasional small mouse as a treat, but this isn’t necessary and can be messy.
    2.    Feeding Frequency:
    •    Juveniles: Feed 2–3 times per week.
    •    Adults: Feed once a week.
    •    Avoid overfeeding; a plump abdomen is a sign of a well-fed tarantula.
    3.    Prey Size:
Prey should be no larger than the tarantula’s abdomen.
 
Behavior
    1.    Temperament:
Lasiodora subcanens are generally skittish and can flick urticating hairs when threatened. Handle only if necessary.
    2.    Molting:
During molting, they will stop eating and may appear lethargic. Ensure the enclosure is humid enough to aid the process.
 
General Tips
    •    Cleaning: Remove uneaten prey within 24 hours to prevent mold or mites. Spot-clean regularly and do a deep clean every 6–12 months.
    •    Growth: These tarantulas can grow up to 8–9 inches in leg span, so prepare for their large adult size.
    •    Observation: Watch for signs of stress, such as excessive burrowing, climbing the walls, or refusal to eat for extended periods outside of molting.
 
With proper care, Lasiodora subcanens can live up to 15 years in captivity.
