Keeping boa constrictors: profile and care

At a glance

• Adult size: 120 to over 300 cm depending on subspecies (males usually smaller)
• Origin: Central and South America
• Suitable for beginners: no – their size means experience is required
• Lifespan: 20–30 years

The right vivarium

At least 180 x 80 x 80 cm for adults, and larger for bigger specimens. With a robust substrate such as bark chippings, sturdy climbing branches, hides and a water container large enough to bathe in.

Temperature, lighting & climate

• Daytime 28–32 °C, basking spot up to 35 °C
• Night-time 22–25 °C
• Humidity around 60–75 %, slightly higher for some subspecies
• Heat lamp, UVB lighting and a thermostat-controlled heat mat

Feeding

Frozen-thawed food such as rats or rabbits: juveniles every 10–14 days, adults roughly every 3–4 weeks. Avoid overfeeding, as boas put on weight easily.

Temperament & handling

A calm temperament, active around dusk and at night, and generally not aggressive. Powerful nonetheless, so handle with respect – not an animal for children.
