Boa Constrictor

Overview

Boa constrictors (Boa constrictor) are heavy-bodied constrictors native to Central and South America. Depending on locality and subspecies, adults range from 6 to 10 feet, with some Common (BCI) females exceeding that. They live 20-30 years and require committed keepers prepared for a large, strong snake.

Enclosure

An adult boa needs at least 6 x 2 x 2 feet of enclosure space, with 8 x 2 x 2 feet preferred for large females. PVC or sealed wood enclosures are strongly recommended for heat and humidity retention. Provide sturdy climbing branches, two large hides, and a water bowl big enough to soak in. Suitable substrates include cypress mulch, coconut husk, or bioactive mixes.

Temperature and humidity

Maintain a warm side of 88-92F and a cool side of 78-82F, with a slight nighttime drop. Humidity should sit at 55-70%, climbing during sheds. Use radiant heat panels or ceramic heat emitters controlled by a thermostat. Heat rocks are not safe.

Diet

Feed appropriately sized frozen-thawed rats. Young boas eat every 7-10 days; sub-adults every 10-14 days; adults every 14-21 days, scaling back further as growth slows. Avoid power-feeding; obese boas are extremely common in captivity and obesity shortens lifespan significantly.

Handling and temperament

Boas are generally calm and tolerate handling well once acclimated. Their size and strength demand respect: never handle a large boa alone, and never let one wrap around your neck. Wait at least 48-72 hours after a meal before handling.

Common health issues

Watch for respiratory infections, scale rot, mites, and obesity. Boas can carry Inclusion Body Disease; quarantine new arrivals for 90+ days and keep them away from other boids during that time.
