A powerful yet generally docile species, the Common Boa is a rewarding snake for experienced keepers with space for a large enclosure.
Difficulty: Intermediate
Lifespan: 20–30+ years
Adult Size: 6–8 feet (occasionally larger)
Enclosure Size: 4–6 ft long minimum for adults
Temperament: Calm and handleable, though strong and inquisitive

🏠 Enclosure

• Minimum adult size: 120–180 cm (4–6 ft) enclosure

• Type: Sturdy, escape-proof vivarium or PVC enclosure

• Ventilation: Moderate, avoid overly dry or humid conditions

• Juveniles can be housed in smaller setups but will outgrow them quickly

🌿 Substrate & Décor

• Substrate: Coco fibre, cypress mulch, orchid bark, or soil mix

• Depth: 2–4 inches for spot cleaning and humidity retention

• Décor: Branches (they enjoy climbing), hides at both ends, cork bark, leaf litter

• Provide a large water dish—many boas enjoy soaking

🌡️ Temperature & Heating

• Warm side: 30–32°C (86–90°F)

• Cool side: 24–26°C (75–79°F)

• Night drop: 22–24°C (72–75°F)

• Use a basking lamp, ceramic heat emitter, or heat panel with thermostat

💡 Lighting

• UVB not required but optional low-level UVB (5–6%) may support wellbeing

• Provide a natural 12-hour day/night cycle with ambient room lighting or LED

💧 Humidity

• Ideal range: 55–70%

• Mist lightly if needed, especially during shed

• Ensure good airflow to prevent stagnant moisture

• Include a moist hide or moss box if shedding issues occur

💧 Water

• Use a large, sturdy water bowl

• Clean and refill regularly—helps with humidity and soaking

🥩 Feeding

• Diet: Frozen-thawed rodents up to appropriately sized rabbits for large adults

• Feed prey not much larger than the widest part of the snake's body

• Schedule:

  • Juveniles: Every 7–10 days

  • Adults: Every 14–21 days

  • Avoid overfeeding—boas can become overweight easily

⚠️ Handling & Behaviour

• Generally calm and tolerant of handling

• Always support the body fully with both hands

• Never handle after feeding or during shed

• Be mindful of their size and strength—these snakes are muscular

🧼 Cleaning

• Spot clean weekly

• Replace substrate every 6–8 weeks or as needed

• Disinfect water bowl and surfaces regularly
