Common questions

What size enclosure does a boa constrictor need?

At least 72 × 36 × 48 inches (183 × 91 × 122 cm) for one adult, about 539 gallons. Floor space matters more than height for this species. Bigger is always better if you have room.

What temperature should a boa constrictor enclosure be?

Aim for a warm side of 90-95°F and a cool side of 75-80°F, so it can move between the two to control its body temperature. Check with a digital probe thermometer, not a stick-on dial.

What humidity does a boa constrictor need?

55-75%. A digital hygrometer in the middle of the enclosure gives the most useful reading.

Does a boa constrictor need UVB?

Yes, Zone 1 to 2, which runs from low UVB, suited to shade-dwelling and dawn-and-dusk species to moderate UVB, for animals that bask now and then. Match your bulb and its distance to that level using the maker's chart, and replace it on schedule.

Which common tanks fit an adult boa constrictor?

Of the common sizes, these meet the adult minimum: 6 × 3 × 4 (72 × 36 × 48 in), 8 × 4 × 4 (96 × 48 × 48 in).

These are common hobbyist guidelines for a healthy adult, based mostly on published species care guides. Babies, sick animals and specific localities can need different setups, so check with a reptile vet for anything serious.
