The Complete Guide to Keeping Bahia Scarlet Birdeater Tarantulas

The Bahia Scarlet Birdeater (Lasiodora klugi) is a large, terrestrial New World tarantula known for its impressive size, striking red abdominal hairs, and bold feeding response. Native to Brazil, particularly the Bahia region, this species is a favourite among experienced keepers who appreciate its dramatic appearance and active behaviour.

While often confused with its close relative Lasiodora parahybana, the Bahia Scarlet Birdeater stands out for its richer colouration and slightly more defensive temperament. When provided with the correct conditions, it is a hardy and rewarding species to keep.

What Is a Bahia Scarlet Birdeater?

The Bahia Scarlet Birdeater is a terrestrial tarantula belonging to the Theraphosidae family. It is one of the larger species available in the hobby and is known for its speed, appetite, and defensive displays.

They are:

• Large: Leg spans of 20–25 cm are common in adults

• Terrestrial: Ground-dwelling and burrow-inclined

• Fast-growing: Especially during juvenile stages

• Defensive: More prone to flicking hairs and threat postures

This species is best suited to intermediate or experienced keepers due to its temperament and size.

Enclosure Requirements

Tank Size

Bahia Scarlet Birdeaters require more floor space than height.

• Spiderlings: Small tubs or vials with ventilation

• Juveniles: 15–20 cm enclosures

• Adults: Minimum 30 x 30 x 30 cm enclosure

A general rule is to provide at least 2–3 times the spider’s leg span in floor space.

Enclosure Type

A well-ventilated terrestrial setup is essential.

Suitable enclosures include:

• Glass terrariums

• Plastic tubs with cross ventilation

• Acrylic enclosures designed for tarantulas

Ensure the enclosure is secure, as this species is strong and can push lids if not properly fastened.

Substrate

Deep substrate is important, as this species may burrow, especially when young.

Recommended substrates:

• Coco fibre (coir)

• Topsoil (chemical-free)

• Soil/sand mixes for structure

Provide at least 10–15 cm depth for juveniles and adults.

Keep substrate slightly moist but not waterlogged.

Temperature and Humidity

As a tropical species, L. klugi thrives in warm, moderately humid conditions.

• Temperature: 24–28°C

• Humidity: 65–75%

Maintain humidity by lightly moistening part of the substrate and providing a water dish. Good ventilation is crucial to prevent stagnant conditions.

Lighting

No special lighting is required.

• Avoid direct sunlight

• Ambient room lighting is sufficient

Tarantulas are nocturnal and do not benefit from bright lighting.

Decor and Hiding Spots

Providing a secure hide is essential for reducing stress.

Include:

• Cork bark hides

• Half logs or artificial caves

• Leaf litter for cover

While they may not always use a hide as adults, it should always be available.

Avoid tall decorations, as falls can be dangerous for heavy-bodied tarantulas.

Diet and Feeding

Bahia Scarlet Birdeaters are enthusiastic feeders with a strong prey response.

Suitable Prey:

• Crickets

• Locusts

• Dubia roaches

• Mealworms (occasionally)

Feeding Schedule:

• Spiderlings: Every 3–5 days

• Juveniles: Twice weekly

• Adults: Once every 7–10 days

Prey size should be appropriate, generally no larger than the spider’s abdomen.

Remove uneaten prey after 24 hours to avoid stress or injury.

Fresh water should always be available in a shallow dish.

Behaviour and Temperament

This species is known for being more defensive than many beginner tarantulas.

Typical behaviours:

• Hair flicking when disturbed

• Threat postures (raising front legs)

• Rapid retreat or sudden bursts of speed

They are not typically aggressive but will defend themselves if provoked.

Handling is strongly discouraged due to:

• Risk of bites

• Urticating hairs causing irritation

• Potential injury from falls

Observation is the best way to enjoy this species.

Moulting

Moulting is a critical process for growth.

Signs of premoult:

• Reduced appetite

• Darkening abdomen

• Lethargy

During moulting:

• The tarantula may lie on its back

• Do not disturb

After moulting:

• Allow 7–14 days before feeding

• Fangs must harden before prey is offered

Maintain stable humidity to support successful moults.

Breeding

Breeding Lasiodora klugi is possible but requires experience.

• Males mature faster and have shorter lifespans

• Females can produce large egg sacs

• Spiderlings grow quickly and require frequent feeding

As with many tarantulas, breeding should only be attempted with proper research and preparation.

Common Health Issues

This species is generally hardy, but issues can arise from poor care.

Watch for:

• Dehydration (shrivelled abdomen)

• Mite infestations

• Failed moults

• Lethargy or refusal to eat

Most problems are linked to incorrect humidity, temperature, or hygiene.

Lifespan and General Care

• Females: 15–20 years

• Males: 3–5 years

• Growth rate: Fast

Routine care includes maintaining clean conditions, providing fresh water, and monitoring behaviour.

Conclusion

The Bahia Scarlet Birdeater is a bold, impressive tarantula that offers both visual appeal and engaging behaviour. Its size, feeding response, and vibrant colouring make it a standout species in any collection.

However, its defensive nature and speed mean it is not ideal for beginners. With proper respect, suitable housing, and consistent care, Lasiodora klugi can be a long-lived and fascinating addition for experienced keepers.
