Terrestrial Tarantula Care Guide

Complete Care, Enclosure & Husbandry Guide

Terrestrial tarantulas are among the most popular and rewarding species in the hobby. Known for their bold appearance, fascinating behavior, and generally manageable care requirements, these ground-dwelling tarantulas make excellent additions for both beginner and experienced keepers.

At House of MyNia, we believe proper husbandry begins with thoughtfully designed habitats that prioritize safety, functionality, and long-term health. This guide covers the foundational care requirements for most commonly kept terrestrial tarantula species.

Understanding Terrestrial Tarantulas

Terrestrial tarantulas are ground-dwelling species that spend most of their time on or near the substrate. Many species will:

• Create shallow burrows
• Rearrange substrate
• Build retreats under cork bark or hides
• Sit openly on display

Unlike arboreal species, terrestrial tarantulas require wider floor space and lower enclosure height to reduce the risk of dangerous falls.

Enclosure Requirements

Proper Enclosure Size

A terrestrial tarantula enclosure should prioritize floor space over height.

Recommended Guidelines:

• Enclosure floor space should be approximately:
  • 3–4x the tarantula’s leg span in length
  • 2–3x the tarantula’s leg span in width

Avoid excessive enclosure height.

Tarantulas have heavy abdomens and can be seriously injured or killed by falls, especially larger species.

Important Fall Safety Warning

One of the most common mistakes in terrestrial tarantula keeping is providing too much vertical space.

Unlike arboreal species, terrestrial tarantulas are not designed for climbing significant heights. Falls can result in:

• Ruptured abdomens
• Internal injuries
• Fatal trauma

To reduce risk:

• Keep climbing opportunities low
• Provide deep substrate
• Avoid hard decorations or sharp surfaces
• Limit excessive enclosure height

At House of MyNia, we strongly prioritize safety-focused enclosure design over aesthetics alone.

Ventilation

Proper airflow is essential for maintaining a healthy environment.

Poor ventilation may contribute to:

• Mold growth
• Stagnant humidity
• Bacterial buildup
• Respiratory stress

Cross ventilation is strongly recommended for most species.

Temperature & Humidity

Requirements vary by species, but most commonly kept terrestrial tarantulas thrive within the following ranges:

General Care Parameters:

• Temperature: 72–80°F
• Humidity: Species dependent (typically low to moderate)

Always research the specific needs of your species.

Some species prefer:

• Dry conditions (Grammostola, Brachypelma)
• Moderate humidity (Acanthoscurria, Lasiodora)

Avoid excessively damp conditions unless specifically required.

Substrate Requirements

Substrate is one of the most important elements of a terrestrial tarantula enclosure.

It helps:

• Cushion falls
• Maintain humidity
• Support burrowing behavior
• Create natural security

Recommended Substrates:

• Cocoa coir
• Organic topsoil (fertilizer-free)
• Reptisoil
• Bioactive substrate blends

Recommended Depth:

• At least 2–6 inches depending on species and size

Burrowing species may require significantly deeper substrate.

Hides & Decoration

Every terrestrial tarantula should have access to a secure retreat.

Recommended Hides:

• Cork bark
• Half logs
• Artificial caves
• Naturalistic retreats

Decoration should remain practical and safe.

Avoid:

• Sharp décor
• Heavy objects that may collapse
• Excessive climbing opportunities

Water & Hydration

Fresh water should always be available for juvenile and adult tarantulas.

Water Dish Recommendations:

• Shallow dish
• Easy access
• Cleaned regularly

Light moisture can be maintained for humidity-dependent species, but avoid overly wet substrate unless the species specifically requires it.

Feeding

Tarantulas are opportunistic ambush predators and should be fed appropriately sized live prey.

Common Feeder Options:

• Roaches
• Crickets
• Mealworms
• Superworms
• Occasional hornworms

Feeding Rule:

Prey should generally not exceed the size of the tarantula’s abdomen.

Overfeeding can increase the risk of:

• Obesity
• Fall injuries
• Molting complications

Important Feeder Insect Disclaimer

At House of MyNia, we strongly recommend sourcing feeder insects from trusted breeders or reputable specialty suppliers whenever possible.

Many hobbyists within the exotic pet community have reported concerns regarding feeder insects purchased from certain large chain or “big box” pet stores, including claims of potential parasites, pesticides, or contaminants that may negatively affect sensitive species such as:

• Tarantulas
• Jumping spiders
• Praying mantises
• Reptiles
• Other invertebrates

While we cannot independently verify all of these claims, we believe it is always best to prioritize caution and quality when it comes to the health of your animals.

We recommend:

• Purchasing feeders from reputable sources
• Avoiding unhealthy or poorly maintained feeders
• Properly caring for feeder insects prior to use

Molting

Molting is one of the most vulnerable stages of a tarantula’s life.

Before molting, tarantulas may:

• Refuse food
• Become lethargic
• Seal themselves inside burrows
• Lay down a molting mat

During Molting:

Never disturb a tarantula during this process.

Tarantulas often molt on their backs, which is completely normal.

Successful molts require:

• Stable conditions
• Proper hydration
• Minimal disturbance
• Safe enclosure design

Never feed immediately after a molt. Wait until the fangs have fully hardened.

Cleaning & Maintenance

Routine maintenance helps maintain healthy enclosure conditions.

Recommended Maintenance:

• Remove uneaten prey promptly
• Spot clean waste regularly
• Clean water dishes frequently
• Monitor humidity and ventilation

Avoid excessive disturbance, especially for shy or burrowing species.

Handling

While some terrestrial tarantulas are calm, handling is generally discouraged.

Even docile species may:

• Bolt unexpectedly
• Flick urticating hairs
• Fall and become injured

If handling is attempted:

• Keep the tarantula low to the ground
• Move slowly and calmly
• Never force interaction

At House of MyNia, we recommend appreciating tarantulas primarily as display animals.

Cohabitation Warning

Terrestrial tarantulas should almost always be housed individually.

Housing multiple tarantulas together may result in:

• Stress
• Competition
• Cannibalism
• Serious injury or death

Common Beginner Mistakes

• Excessive enclosure height
• Overfeeding
• Poor ventilation
• Overly wet substrate
• Unsafe decorations
• Disturbing tarantulas during molts
• Cohabitation

Final Thoughts

Terrestrial tarantulas are incredible animals that reward patient, thoughtful husbandry. With proper enclosure design, safe substrate depth, ventilation, hydration, and feeding practices, these species can thrive for many years and display fascinating natural behaviors.

At House of MyNia, we believe thoughtfully designed habitats create safer, healthier, and more enriching environments for both keeper and animal.
