About the Dumerilโs Boa
- We donโt recommend Dumerilโs boas for newbie snake keepers.
- Acrantophis dumerili is readily and legally available through breeders.
- According to the International Union for Conservation of Nature (IUCN), the Dumerilโs boa is vulnerable to human encroachment.
- The Convention on International Trade of Endangered Species (CITES) classifies Acrantophis dumerili as a species in danger of extinction.
What do Dumerilโs Boas Look Like?
Dumerilโs boas have a stocky build.
The coloration of this snakeโs skin varies widely. It can range from tan, to brown, peach, gray, red, or green.
People often confuse the Dumerilโs boa and the Madagascar ground boa, Acrantophis madagascariensis, which have similar appearances.
Dumerilโs Boa Size
A medium-sized snake, adult Dumerilโs boas average three to six feet in length. Females are larger than males.
Baby Dumerilโs boas measure 12 to 18 inches in length.
Dumerilโs boas have a slow growth rate, so it can take three to five years for them to reach maturity.
The similar Madagascar ground boa, Acrantophis madagascariensis, is a larger snake. Adult females sometimes reach ten feet long.
Habitat and Distribution of the Dumerilโs Boa
These reptiles come from southwestern Madagascar. They inhabit drier regions, where thereโs minimal rainfall.
Still, their habitat isnโt desert-like, something important to keep in mind when setting up their enclosure.
This snake is a ground dweller, and itโs active at night. They prefer the dry forest floor where leaf litter accumulates.
Where Can I get a Dumerilโs Boa?
Theyโre readily available online through breeders, though you can sometimes find them for sale at reptile expos. Only captive-bred Dumerilโs boas are available for sale.
We recommend getting your pet snake from a reputable breeder, as youโll be more likely to get a healthy reptile.
Is the Dumerilโs Boa a Threatened Species?
CITES classifies Acrantophis dumerili as an Appendix I species, meaning that itโs at risk of extinction.
IUCN lists these snakes as being vulnerable due to habitat destruction, war, and other forms of human encroachment.
How Long do Dumerilโs Boas Live?
The lifespan for Dumerilโs boas ranges from 10 to 20 years. Captive specimens may live for more than 20 years.
Dumerilโs Boa Enclosure Size
As Dumerilโs boas are ground-dwelling, you should focus on the length of the enclosure. But of course, the enclosure height is still important to consider.
This snake will climb given the opportunity; plus, climbing is a form of enrichment.
- For baby Dumerilโs boas (two feet or less in length), an enclosure measuring 2โฒ (L) x 1.5โฒ (W) x 1.5โฒ (H) is adequate.
- For young Dumerilโs boas and sub-adults (between two and five feet in length), the enclosure should measure 4โฒ (L) x 2โฒ (W) x 2โฒ (H).
- The housing for adult snakes (six to eight feet in length) should measure 6โฒ (L) x 2โฒ (W) x 2โฒ (H).
- You should house Dumerilโs boas larger than eight feet in an enclosure thatโs 8โฒ (L) x 2โฒ (W) x 2โฒ (H).
The opening to the enclosure should be in the front as opposed to the top. In the wild, predators of snakes often strike from above.
Having the opening of the enclosure in front will make your snake feel more secure, and it will be easier for you when youโre maintaining the enclosure.
Furnishing a Dumerilโs Boa Enclosure
By adding certain elements to the boaโs enclosure, you can make it feel secure.
The following segments cover elements that you should include in your pet snakeโs enclosure:
Water Dish
Equip the enclosure with a water dish thatโs large enough for your Dumerilโs boa to submerge itself completely.
Change the water whenever itโs dirty and at least twice a week regardless of the waterโs appearance.
Hides
Dumerilโs boas are shy snakes, so providing hide boxes for your pet is important.
The hides need to be big enough for your snake to coil up completely inside them. They shouldnโt be any larger than that.
To feel secure, your snake needs to be able to feel the walls of the hides touching its scales.
For smaller snakes, this is easy. Many pet stores sell artificial caves, hollow logs, or other ornaments that make good hides.
For large snakes, you may have to make a hide yourself. Hides for larger snakes can range from 18 x 18 inches to 18 x 24 inches.
You can use an upside-down storage tub or kitty litter tray and cut an entry hole on the side. Provide two to three hides in the enclosure.
Place one hide box on each end of the exhibit so that your snake will have a place to hide on either end of the thermal gradient.
Humid Hides
You can choose to use the hide box on the cooler end of the enclosure, or to provide a third hide as a humid box.
Whichever you choose, line one of the hides with damp sphagnum moss to create a humid retreat. Spray the sphagnum moss as needed to keep it moist.
The moss will provide a high-humidity area during shedding time to help your Dumerilโs boa shed successfully.
Branches
While Dumerilโs boas spend most of their time on the ground, giving them an opportunity to climb will serve as a form of enrichment for them.
As part of your Dumerilโs boa care, install branches that are large enough to support your snakeโs weight.
Itโs also important to secure the branches so that they donโt topple while your snake is climbing on them.
For plastic or glass enclosures, you can use wire to secure the branches. If the enclosure is made of wood, you can use screws to secure the branches.
If you use screws, make sure not to leave any exposed that could injure your snake.
Enclosure Construction
Whether youโre purchasing an enclosure or building it yourself, itโs important to consider the materials used to construct the enclosure. Letโs take a look at common enclosure materials:
Glass
The disadvantages of glass enclosures are:
- Theyโre less durable.
- Theyโre more expensive.
- They make it more difficult to maintain consistent temperatures and humidity levels.
The advantage of using glass enclosures is that glass is great for dissipating heat.
Yes, the disadvantage of using glass (maintaining consistent temperatures and humidity levels) is an advantage when keeping Dumerilโs boas!
As a building material, glass is great when it comes to dissipating heat. This quality helps maintain temperature gradients (see the Temperature section).
Glass enclosures are also easy to clean.
Pro Tip: If you select a glass enclosure, tape construction paper to cover all sides of the enclosure, except the front.
By covering up the sides of the tank, your snake will feel more secure and wonโt feel like itโs in an open and exposed area.
PVC and HDPE
Enclosures made of PVC (polyvinyl chloride) and HDPE (high-density polyethylene) are popular with reptile keepers because:
- Theyโre durable.
- They retain heat and humidity.
- Theyโre lightweight and easy to clean.
- Theyโre opaque, which gives reptiles a sense of security.
Wood and Melamine
Hobbyists who build their own enclosures often use wood. It has the advantage of being easy to obtain, lightweight, and inexpensive.
Wood and melamine (a kind of plastic) donโt hold up well to humidity.
Wood can also rot and become moldy, so you should treat it with a non-toxic waterproofing sealer.
Donโt use sealants that contain volatile organic compounds (VOCs). VOCs can be harmful to humans, and reptiles are especially sensitive to them.
Recommended sealants include:
- Epoxy
- Kennel Seal
- Pond Armor
Dumerilโs Boa Care
The care of Dumerilโs boas isnโt difficult. However, some of the care requirements for this snake differ from other boas. The following are the care requirements for this reptile.
Substrate
In Madagascar, the natural habitat of Acrantophis dumerili is the dry leaf litter of the dry forest floor. The leaf litter gives them a place to burrow.
When choosing a substrate for your snake, itโs important to remember that they like to burrow.
The substrate for your pet snake should be at least four to six inches deep.
Besides allowing your snake to burrow, the proper substrate will also help regulate the enclosureโs humidity.
The most recommended substrates for Dumerilโs boas are:
- Exo Terra Desert Sand, Red: Costs around $15/10lbs.
- Zoo Med Reptisand, Natural Red: Costs around $15/10lbs.
- Lugarti Natural Reptile Bedding: It will cost you about $11 for a 10-quart bag.
- The BioDude Terra Sahara: Around $50 for 36 quarts. While expensive, it will last a long time.
- A 60% topsoil, 40% play sand blend. Itโs easy to make, and the topsoil and play sand are also cheap and widely available.
- Jurassic Reptile Substrate: While expensive ($20 for 4 quarts), this substrate closely resembles the Dumerilโs boaโs natural habitat.
Pro Tip: Regardless of the substrate that you use, add leaf litter to it. Your Dumerilโs boa will love it!
Other acceptable substrates include:
- Reptichip
- Aspen chips
- Cypress mulch (donโt use the blend)
Your most basic substrate options would be:
- Newspaper
- Paper towels
- Butcher paper
The most basic substrates are best for snakes that are in quarantine.
These substrates make it easy to detect any mites, and theyโre easy to clean. However, they offer no enrichment for your Dumerilโs boa.
Donโt use cedar or pine shavings for reptiles. Cedar or pine shavings contain oils and fumes that can cause burns and neurological damage to your pet.
Lighting
Even though these snakes are nocturnal, we recommend providing UVB lighting as part of a Dumerilโs boa care.
UVB lighting has been shown to provide long-term benefits to the health of a Dumerilโs boa.
For Dumerilโs boas, itโs best to use low-intensity fluorescent lighting. Recommended bulbs include:
- Zoo Med ReptiSun 5.0 T5HO
- Arcadia Forest 6%
Itโs important to replace the bulbs every 12 months as they diminish in their output with time, even if theyโre working.
When using UVB lighting, itโs important that the bulb is the proper distance from your Dumerilโs boa to ensure that it doesnโt get underexposed or overexposed to the UVB lighting.
You can estimate the distance by using the following guidelines:
- If the UVB bulb doesnโt have a protective screen, it should be 12-15 inches above the basking area.
- If a protective screen or mesh surrounds the UVB bulb, the bulb should be 9-12 inches above the snakeโs basking area.
Pro Tip: When you buy them, UVB bulbs are sometimes covered with a plastic or glass protective sleeve. Be sure to remove the sleeve, or the bulb wonโt be able to emit UVB rays.
We recommend offering your Dumerilโs boa a day and night cycle. An automatic timer will make this much easier for you.
You can adjust the lighting to the seasonal cycles by setting the timer. The following guidelines mimic a Dumerilโs boaโs natural seasonal exposure to light in the wild:
- During Spring, offer 12 hours of light per day.
- In Summer, offer 13 hours of light.
- During Fall, offer 12 hours of light.
- For Winter, offer 11 hours of light.
Dumerilโs Boa Temperature Requirements
Warm-blooded animals can make adjustments to their body temperature internally. They donโt depend on the temperature of their surroundings to achieve their optimal temperature.
Dumerilโs boas, like other reptiles, are unable to regulate their body temperature internally.
They depend on their surrounding temperature to achieve their optimal temperature.
Part of a Dumerilโs boa care includes setting up the enclosure so that thereโs a cool side and a warm side; thus, creating a thermal gradient for your reptile:
- Keep the warm side between 86-88ยฐF (30-31ยฐC).
- The cool side of the enclosure can be from 70-75ยฐF (21-24ยฐ).
Dumerilโs Boas love to bask, and appreciate a basking lamp. - At night, the temperature for Dumerilโs boas can drop to 68-75ยฐF (21-24ยฐC).
You may be able to reach the nighttime temperature simply by turning off the heat source of your Dumerilโs boas.
If the nights are too cool, you can provide your Dumerilโs boas with a heat panel.
Humidity
The southeast coast of Madagascar only receives an annual rainfall of 250 mm.
The habitat of Acrantophis dumerili is dry. However, that doesnโt mean that humidity isnโt important to these snakes.
You should keep the humidity levels for these snakes between 40-60%.
Depending on the humidity level of your area, you might be able to achieve the recommended range by hand misting the animalโs home.
A large water dish can also help to attain the correct humidity level. You can also get an automatic mister.
Heating a Dumerilโs Boa Enclosure
There are many useful devices for heating a Dumerilโs boa enclosure. Letโs take a closer look at some of the best options:
Halogen Flood Heat Lamp
In nature, the land is heated by the sun, not from below ground. Yet, keepers often use heating pads to warm the enclosure.
This makes no sense, especially if youโre dealing with burrowing reptiles. Burrowing reptiles go underground to escape the heat.
For this reason, halogen flood heat lamps are the best option for heating the enclosures of Dumerilโs boas.
Depending on the temperature of your room and the height of the enclosure, the wattage of the bulb will probably range between 75 and 100.
You can also consider using a dimmer switch to lower the temperature if the enclosure gets too hot.
Radiant Heat Panel and Ceramic Heaters
You can use these heat sources for Dumerilโs boas at night. However, you shouldnโt use them for daytime heating.
Ceramic heaters emit ambient heat, which is the weakest kind of infrared heat. However, it will replicate the heat that wild Dumerilโs boas experience at night.
If the enclosure is large, radiant heat panels would be more effective than ceramic heaters for keeping the temperature up at night.
Heat Mats
Keepers commonly use heat mats with terrestrial snakes; however, you should use them with a thermostat.
Use them to heat hide boxes or other hiding areas, as theyโre not powerful enough to heat the air.
Never use heat rocks with reptiles as they may burn animals that come into contact with them.
Always cover a halogen bulb with a wire mesh to prevent your snake from coming in contact with it.
Feeding Dumerilโs Boas
Dumerilโs boas will eat mice and rats. However, you can also feed them:
- Quail
- Chicks
- Gerbils
- Hamsters
- Guinea pigs
As with other animals, itโs better to feed your snake a variety of prey items. Doing so will give your snake a broader range of nutrition.
You should only feed dead feeders to Dumerilโs boas. Live prey, especially rats and mice, may injure or even kill snakes.
Sometimes, Dumerilโs boas wonโt eat dead feeders. If this happens, never put live feeders in the snakeโs cage and walk away.
Watch the feeder carefully to make sure the prey doesnโt harm your snake. If your snake doesnโt eat it, take the prey out of the cage!
What Size Prey Should You Feed Dumerilโs Boas?
The prey item should be no larger than the widest part of your snakeโs body.
Itโs better to err on the side of caution and provide slightly smaller prey than to give your boa food thatโs too big.
How Much Should You Feed Dumerilโs Boas?
The best way to work out how much to feed your snake is by weight.
Weigh the food items and then refer to the following guidelines for how much to feed your snake per meal:
- Feed baby Dumerilโs boas ( under 22โณ long) 20-30 grams.
- Give juvenile Dumerilโs boas (2-3โฒ long) prey weighing 30-40 grams.
- Older juvenile Dumerilโs boas (3-4โฒ long) can consume 40-70 grams.
- Small adult and subadult Dumerilโs boas (4-6โฒ long) can have 70-130 grams.
- Give large adult Dumerilโs boas (7โฒ and longer) 130-250 grams.
How Often Should You Feed Your Dumerilโs Boa?
- You should feed baby and juvenile Dumerilโs boas (less than 3โฒ in length) every 7-10 days.
- Subadult Dumerilโs boas (longer than 3โฒ in length) can eat every 14-20 days.
- Feed adult Dumerilโs boas (Over 3โฒ feet in length or no longer growing) every 21-28 days.
Is it Normal for Dumerilโs Boas to Stop Eating Sometimes?
Yes it is. As with all snakes, Dumerilโs Boas will stop eating before shedding.
The change of seasons can also affect your snakeโs appetite. Adult Dumerilโs boas often stop eating during winter.
However, baby snakes will continue to eat during winter if kept warm.
As long as your snakeโs overall condition looks good and it has a good body weight, there should be no need for concern. Continue to offer your snake food every two weeks.
Pro Tip: The Dumerilโs boa is nocturnal, which is when it does most of its hunting. If you have a picky snake thatโs not eating, try feeding it at night.
What Do I Do with a Dumerilโs Boa That Will Only Eat Live Feeders?
As stated earlier, you shouldnโt offer live prey to snakes as live prey may injure or even kill snakes.
But, what do you do if your snake refuses to make the transition from live food to dead feeders? Try this trick:
First, get your snake hungry by skipping a feeding.
Next, itโs important to remember that some snake species, like boas, detect their warm-blooded prey through the use of special sensory organs.
It may not be enough to thaw your frozen feeders; try warming them up. You can do this by putting the thawed feeder in a plastic zip-lock bag and letting it float in warm water.
You can also try putting the thawed feeder under a heat lamp or warming it up with a hairdryer.
When the feeder is warm, present it to your snake. You can also use tongs to present the feeder to your snake.
Handling a Dumerilโs Boa
Dumerilโs boas have a great temperament and rarely bite.
However, we recommend observing the following guidelines for the safety of your snake and yourself:
Use Snake Hooks
Snake hooks are useful for handling your snake, especially when you first get to know your boa.
Use the snake hook when you need to remove the snake from its home. To do this, open the snakeโs cage and give it a gentle nudge to get its attention.
You can tell that your snakeโs attention is on you when its tongue starts to flicker.
When you have your snakeโs attention, you can use the hook to remove it from its home. You can use your hands to handle the snake when it has been safely removed.
Dumerilโs boas are bulky snakes, so itโs important to support the snakeโs body. Never hold your snake by the end of its tail or by its neck. Doing this can lead to spinal injury.
Keep a close eye on your snake while handling it and become familiar with its body language.
If your Dumerilโs boa rapidly flicks its tongue from a coiled position, it may be preparing for a strike.
If you observe this behavior, distract the snake to get its attention away from you.
Donโt Rush the Introduction
Take it slow when getting acquainted with your snake. Itโs important to give your snake time to get used to you.
Donโt handle your Dumerilโs boa for the first few days so that it can get used to its new home.
When you first start handling your snake, do so only for three to five minutes every other day for a week. You can gradually increase the time as your snake gets to know you.
Regardless of how well your snake responds to you, donโt handle it for more than 20-30 minutes at a time.
Donโt handle your snake for 24-48 hours after feeding it. Doing so may lead to it regurgitating its food.
