Red-Tailed Boa Care Sheet

Developed with and approved by a qualified veterinarian.



The name “red-tailed boa” refers to a group of species—rather than a specific species—of snakes with red tails who originated in Central and South America. These snakes get very large (typically 8 to 10 feet long), so they require a large area for housing and need consistent interaction with humans to become and remain tame. 

Typical red-tailed boa appearance & behavior

  • This nonvenomous snake comes in shades of gray, brown and cream. The darker brown/red markings on their tail give them their name
  • When socialized properly with daily handling, red-tailed boas can become quite docile, and many seem to enjoy being held. When held, they typically move around initially and then settle down on their caretaker’s body to absorb heat
  • As a snake gets ready to shed, their eyes will turn a milky blue/gray over the course of a few days, and their body color will start to dull and develop a whitish sheen. As shedding occurs, some snakes become irritable and should not be handled. Snakes should shed skin all in one piece; if skin is shed in bits and pieces it indicates that their habitat humidity is likely too low
  • Appetite may vary depending on temperature and time of shedding. They often don’t eat while shedding


Care Difficulty Intermediate
Average Life Span Up to 20+ years with proper care
Average Adult Size Up to 10 feet long
Diet Carnivore
Minimum Habitat Size 20-gallon long tank for a juvenile


Habitat size

These snakes get very large (up to 10 feet long and 50 pounds) and may grow 3 to 4 feet in their first year, reaching adult size in 3 to 5 years. A larger habitat must be provided as the snake grows. The habitat should be at least the length of the snake (or longer) to allow them to fully stretch out. Since these snakes are semiarboreal (like to climb trees sometimes), their habitats need some height for vertical climbing. Their tank should have a well-fitting screened top to allow adequate ventilation but prevent escape.

Building your habitat


  • Paper-based bedding, reptile carpet, Aspen shavings or cypress mulch can be used as substrate. Aspen shavings and cypress mulch must be changed frequently, as these can hold water and tend to get moldy. Cedar shavings should never be used, as they contain oils that can irritate snakes’ skin


  • Provide hiding areas large enough for your snake to fit inside to help reduce their stress level and allow them to thermoregulate 
  • Ideally there should be one hide box on the cool side of the habitat and one on the hot side 
  • As these snakes like to climb (especially when they are younger), they should be provided with commercially available branches and/or shelves (safer for heavier snakes) to climb on 
  • Snakes should also have a rock or log resin décor with a rough surface on which they can rub to aid in shedding skin
  • Plants and a background can be added to complement the aesthetics of your habitat


  •  While red-tailed boas do not require ultraviolet (UV) B light to survive, some studies suggest that UVB light may increase snakes’ activity levels and aid in their overall health. Providing snakes with a low-level UVB light helps provide the clear day/night cycle (with 10 to 12 hours of daylight) that boas need to perform their normal daily activities. UV bulbs should be replaced every six months, as their potency wanes
  • These snakes tend to be more active at dawn and dusk (crepuscular). At night, lights should be turned off, or a nocturnal or infrared light can be used 


  • Boas are ectothermic reptiles, which means they rely on their environmental temperature to control their body temperature. To help them regulate their body temperatures, their habitat should have a temperature gradient (90 to 95°F at the warm end and 75 to 80°F at the cool end/nighttime)
  • Heat may be provided by a heat bulb, ceramic heat bulb or an under-tank heating pad 
  • Heat sources should be attached to thermostats to regulate temperatures
  • Thermostats are especially important with heating pads, which can get hot and cause burns through the tank floor if not regulated properly 
  • Hot rocks should not be used as a heat source, as they can burn reptiles
  • Temperature should be monitored with at least two thermometers (one in the hot zone and the other in the cool zone) 
  • Reptiles not kept at the appropriate temperature ranges are more likely to become immunosuppressed and get sick


  • The habitat should contain a water dish large enough for the snake to soak in to help sustain humidity levels, maintain their hydration and aid in shedding 
  • Humidity may also be increased with damp sphagnum moss, which must be changed frequently to prevent mold growth 
  • Humidity levels should be monitored with a humidity gauge and should be maintained at 60 to 70%  
  • Snakes typically require higher humidity during shedding and will often soak before a shed cycle 

Cleaning your habitat

Spot-clean the habitat daily to remove droppings and discarded food. Thoroughly clean and disinfect the habitat at least once per week:

  • Place snake in a secure habitat
  • Remove all substrate and habitat décor
  • Scrub the tank and furnishings with a reptile habitat cleaner or 3% bleach solution
  • Rinse tank and furnishings thoroughly with water, removing all traces of habitat cleaner or bleach smell
  • Dry the tank and furnishings completely
  • Add clean substrate and put furnishings back into the tank
  • Put snake back into their clean, dry habitat


What to feed 

A well-balanced red-tailed boa diet consists of:

  • Appropriately sized frozen rodents, thawed or warmed to above room temperature
  • Small mice may be fed to juveniles; rats are typically fed to adults
  • Live rodents should not be fed, as live rodents will bite snakes who are not hungry and can cause life-threatening injuries. If, under any circumstances, you must offer live rodents to a snake, never leave them unattended in the tank with the snake because of the potential risk for injury to the snake

Things to remember when feeding your red-tailed boa:

  • Do not use a microwave to defrost frozen rodents, as microwaved rodents can have hot spots that can burn snakes’ mouths when they eat them 
  • Do not prepare frozen rodents for feeding in the same area that you prepare human food. If it is unavoidable, be sure to thoroughly disinfect the area. See the Feeding Frozen/Thawed Foods Care Sheet for more information
  • Feed juveniles once a week, adults every one to two weeks
  • Feed in an empty tank, separate from the habitat, so that the snake doesn’t associate your hand or the habitat lid opening with feeding and doesn’t accidentally ingest bedding off the habitat floor when eating
  • Fresh, clean water should be available at all times in a bowl large enough for the snake to soak in


  • Snakes will regularly shed their skin and the covering over their eyes (called the “eye cap” or spectacle); ensure humidity of habitat is at appropriate level to allow snake to shed properly. Skin should be shed in a single long piece
  • Never try to remove retained eye caps by yourself, as you can easily cause damage. Seek veterinary care if eye caps are retained

Where to buy

Red-tailed boas are available for purchase at your local Petco location. Please call ahead to check availability.

Tank mates 

In general, red-tailed boas are solitary animals who prefer being housed alone unless they are being bred.
