Boomslang (Dispholidus typus)

Of all the venomous snakes offered for sale, one could not describe the boomslang (Dispholidus typus) as being common. The majority of individuals on the market are more likely to be wild-caught imports than captive bred. If you are after one of these snakes, you can find them at reptile stores that trade in venomous snakes, at expos or online reptile shops. Expect to pay around $100 to $130.

Boomslang Legal Issues

Depending on where you live, before you can keep a venomous snake, it may be necessary to be in possession of a venomous snake license. As a responsible snakekeeper, it is imperative that we comply fully with this legislation. Also, one should have a sound knowledge of keeping a range of non-venomous snakes before traveling down the venomous route. Proper procedures should also be set in place should you sustain a bite. All precautions should be taken to prevent a snake from escaping. A harmless snake escaping is bad news; a venomous snake escaping is irresponsible and exposes people to undue risk.

The arboreal boomslang can frequently be found in isolated trees within open clearings.

Boomslang Size

An adult boomslang reaches between 3 to 5 feet in length. In exceptional cases, it may reach more than 6 1/2 feet in some areas of its distribution.

Boomslang Life Span

Properly kept, a boomslang can live 15-plus years when reptile health and wellness is prioritized.


Boomslang Housing

As an arboreal snake, a reptile terrarium/vivarium with good height is important. Boomslangs can be stressed if they do not have the ability to climb, and they should not be kept in off-the-shelf aquariums. A pair could comfortably be housed in a custom cage measuring 6 1/2 feet tall, 5 feet wide and 5 feet long. These are fast-moving snakes. To avoid escapes, have only a small access door for routine maintenance and feeding. The cage should also have some sort of trap box installed, so that the snake can be safely isolated when major husbandry work is required. Make sure the enclosure is secure and has a lock.

The boomslang averages between 3 and 5 feet, but in exceptional cases in some parts of its range, it may exceed six feet.


Boomslang Snake Heating and Lighting

Provide a daytime temperature of 75 to 85 degrees Fahrenheit, dropping to 65 to 68 degrees at night. It is important that humidity is kept low, as these are not wet-loving snakes. If kept in adversely wet conditions, respiratory problems can arise. This can usually be alleviated by fitting ventilation grills in the sidewalls of the cage. A metal grill roof will also be beneficial, as all electrical equipment can be suspended above this. By doing this you reduce the need to open the cage to replace electrical elements as and when they fail.

Boomslang Snake Substrate and Reptile Accessories

When it comes to snake habitat products, the enclosure should be furnished with numerous branches and robust foliage. Most of the snakes time will be spent within the branches, so the vivarium flooring can be any material that suits your preference – newspaper, bark chips, soil/peat etc. and other snake supplies. I used the latter because my vivarium was heavily planted with climbing ivy, a cheese plant and a rubber plant.

Boomslang Diet and Feeding

Boomslangs are active snakes, with a high metabolic rate. They should be fed at least once a week to maintain them in peak condition. In the wild, their staples diet are live reptile food, like chameleons -in Botswana this is the flap-necked chameleon (Chamaeleo dilepis) -and birds. For my captives, I feed day-old chicks. However, I did encounter problems with the state of the chicks. If these were freshly thawed and wet, the snakes would not feed on them. They had to be dry and fluffy. Scent-marked mice would also be taken. Depending on the size of snake and the food, feed two food items per sitting; however, adjust this accordingly to the health of the snake. If it looks thin, increase; if it looks fat, decrease.

Boomslang Water and Humidity

An Exo Terra Reptile Water Dish can be used, and should always be provided for drinking, but some individuals may prefer to “drink” water from the leaves of plants. For this reason, the cage should be lightly misted every other day. You can use an Exo Terra Reptile Mister.


Boomslang Handling and Temperament

Boomslangs are not your average snake, and they should be treated as a dangerous, venomous species. When the need arises to move them from the enclosure for whatever reason, this should be done with the aid of a trap box.

Boomslang Breeding

Breeding boomslangs in captivity seems to be a hit-or-miss affair, coupled with a bit of good luck thrown in. Most captive breeding tends to occur in wild-caught individuals, rather than reared captive-bred stock. Although I maintained a wild-caught pair for several years, they showed only a tentative interest in mating, and nothing transpired from any liaisons.

Prior to the breeding season, the sexes should be separated and kept at 40 to 42 degrees for approximately six weeks. During this time, spray them lightly once a day. When ready to introduce them, raise the temperature of the female’s cage back to normal parameters and introduce the male. Following a gestation period of some 60 days, the female will lay between 10 and 25 leathery eggs. These will be laid in damp vegetation, so it is important to put a container of damp vermiculite or peat/sand mix in the cage. If the female cannot find a suitable substrate in which to lay her eggs, she will do so in the water bowl.

Remove the eggs and artificially incubate them at a temperature of 88 degrees. If all goes well, 65 to 80 days later, the 11-inch babies will hatch out. As it may not be possible to acquire birds of sufficient size, rat pups scent-marked by rubbing them on a chick will be accepted. Any food offered should be done so with a long pair of feeding tongs, as it may be necessary to simulate movement to entice the individual to feed.
