Origin and Habitat of the Dumerils boa 

This species of snakes belong to southwest Madagascar, that is in the Indian ocean.

Southwest Madagascar is relatively arid, with settlements, dry woods, and recently imported tree species aplenty in certain regions. The Dumeril’s boa inhabits these regions and isn’t scared of other ground-dwelling animals or human conflict there.

The color of the dumerils boa is brown, white, and black, in some cases you might even find red, green, and each color combinations over its body. A fun fact about this creature is that it camouflages in the forest.


The size of this snake varies between 4-8 feet, and this snake can weigh about 20 pounds which is 9 kgs! The females are larger in terms of weight and size both, the female dumerils boa has a thick body while the male has a narrower thin tail this is because they require the extra bulk to be able to carry and birth between 6 and 28 live offspring, who are typically between 12 and 18 inches long, during incubation.

The Lifespan of Dumerils boa

In order to fully mature Dumerils boa takes approximately 3 to 5 years, it is a slow-growing snake. The average lifespan of this snake is 20 years or more depending on how well they are taken care of. If they are provided with the necessities and additional care and pampering they can survive for more than 20 years easily.

The Behavior of Dumerils boa.

The camouflaging nature of this snake makes preying easier for them, this snake does not climb places it creeps on the floor. The nature of this snake when it comes to preying is that it will hide in bushes and wait for its prey to pass by and then hunt on it.

Ground boas from Dumeril are nocturnal predators. They will essentially remain still while waiting for an unprepared prey animal to pass for extended periods of time. When the victim is within striking distance, the boa lunges for it, grips it, and chokes it to death.

The Dumerils boa is very friendly, in fact, it is the friendliest snake that you can find out there. It is not territorial, but if you provoke it a lot and give it a sense of you being its prey it will bite you, in order to keep them calm at all times and keep yourself safe, wash your hands well before handling them.

Conversational Status 

Least concern according to the International Union for Conservation of Nature (IUCN) Red List. CITES Appendix I listed, which places severe restrictions on its exporting from Madagascar.

Their population is in decline as a result of habitat degradation for agricultural purposes or to provide pasture for cattle; they are also murdered out of superstition and fear. Markets in Madagascar and other nations both sell their skins.

 They are further exported and marketed as pets. Diet consists of small creatures including frogs, lizards, and birds.

Housing Dumerils boa

While housing Dumerils boa, take special care of the enclosure, substrate, and temperature. These three things are the main factors to take care of, other than this decorations, lighting, etc come secondary.

The health of your snake depends on its environment, these snakes can often feel homesick, to treat this you should replicate their natural habitat, which is a dry forest.

To replicate dry forests, you should use leaves that have fallen from the tree and add broken tree branches, if you can, add some low-lying vegetables too, this really helps mimic the natural environment of the snake.

Another thing that this snake loves to do is hide, provide a box or some sort of rock or nest-shaped bush so the snake can hide when it wants to do so.

Firstly, you must decide what sort of enclosure you want, whether you can be an aquarium, vivarium, or terrarium.

A terrarium is usually the most prescribed option from reptile breeders, a glass terrarium of ten gallons is good for your reptile. The terrarium should be 3 feet tall, five feet long, and at least 2 feet in width.

It’s better to get a large terrarium from the beginning rather than changing them as the snake grows. A big terrarium will prove to be beneficial by providing your snake with enough space to move around in. 

Make sure your enclosure has a proper system for ventilation as you do not want to suffocate your snake, your terrarium should have small holes to let air in, but also make sure the terrarium has a secure lid to prevent your snake from escaping.

Substrate and Decoration

Bedding, the material you use to cover your reptile’s floor, is referred to as “substrate” in some contexts.

 Making the appropriate decisions for Dumeril’s boa substrate may assist with controlling humidity and promoting health. 

The incorrect substrate may sometimes be lethal to your snake and be unclean.

Choosing a substrate for this snake is by far the easiest job to do, you can add a paper towel, brown butcher paper, a Newspaper, and dried leaves as well.

One substrate to avoid at all costs is cedar and pine shavings, the reason behind this is that this sort of substrate contains oil, this oil can damage the skin barrier of your snake, and this can lead to severe neurological issues.

Dumerils boa is ground dwellers, they like to dig into the soil and then move around, this helps with keeping the snake calm, and retaining good mental and physical health of the snake, It reduces the chances of illnesses and also makes your snake feel secure, in order to mimic this you should add at least 4 to 6 inches of substrate.

If you want to make a substrate mix on your own, you can definitely do so by adding topsoil that is 60% organic and 40% play sand. You can get both ingredients for a reasonable price at your neighborhood hardware shop. 

For decoration, you won’t need to send a lot, the most you will have to do is to add a fake tree and a hiding spot, a hiding spot is good to let your snake have some personal time away from humans eyes, and a tree will help your snake climb whenever it feels like doing so.

When providing a hiding box, avoid using cardboard boxes, that is because they aren’t that durable and will break sooner than expected, instead, you can use a plastic tub, cut an opening in it, and flip it upside down, this will create a small den for your snake.

 Although Dumeril’s boas are categorized as mostly terrestrial snakes, they have been seen climbing up tree branches and have been photographed doing so.

 Installing branches in the cage is an excellent method to improve its appearance and give your pet more exercise.

 Although individuals seldom weigh more than 20 to 25 lbs, you will still need to secure any branches that are present to prevent damage from breaking, falling, or exposing screws while in use.

 Cut branches to size and fasten them firmly in place while making your adult Dumeril’s boa habitat if you decide to do so.


According to recent research, UVB is good for the long-term physical and mental well-being of snakes. Utilize a low-intensity fluorescent tube (not a coil) such as the Zoo Med ReptiSun 5.0 T5 HO or the Arcadia Forest 6 percent if you want to use UVB as your main source of light.

 Even though they appear to be functioning, these bulbs should be replaced every 12 months, since, they lose some of their UVB output over time.

Your snake’s basking surface has to be positioned at the proper distance from the source of UVB light since its intensity reduces as you go away from it. Your snake might become “sunburned” if it is too close. Your snake might not truly benefit from having the lamp if it’s too far away.

These snakes sleep during the day and remain active during the night meaning that they are  Crepuscular. so a UVB light is mandatory, they are mainly active around sunsets.

In the terrarium housing your Dumeril’s boa, you should utilize heat lamps or fluorescent lighting during the day. 

Although Dumeril’s boas don’t have any particular lighting needs, you should give them a 12-hour cycle of natural illumination. To control your snake’s light cycle and avoid upsetting its habit, you may attach a timer.

Temperature and Humidity

These snakes belong from dry hot areas, which means that they can live in warm enclosures and require an enclosure mimicking this itself.

On both the chilly end and the heated end of the cage, at least two thermometers should be mounted in the terrarium or aquarium and one inch above the floor. A third thermometer should 

be placed above the resting or basking area as well. When shedding, humidity levels should be kept in the upper range of 40 to 60 percent.

A heat gradient is necessary for Dumeril’s boas to be able to control their own body temperature. Large enclosures are able to provide this temperature differential than tiny terrariums or tubs.

30–31°C for the bathing area: 86–88°F

Cooling zone: 21–4 °C (70–75 °F)

If allowed to do so, nighttime temperatures can safely drop to 68–75°F (21–24°C), which is healthier for the snake’s long-term health.

 Usually, doing this is as simple as turning off the heat source at night. It is advised to employ a mild source of nocturnal heat, such as a ceramic heat emitter or radiant heat panel, detailed below if the snake’s cage is situated in an especially chilly room.


The enclosure of this snake is a little messy, so you will have to maintain it every once in a while, daily spot cleaning is not required as this snake doesn’t eat on daily basis.

You should clean the terrarium or whatever enclosure you have chosen once every month, you can use vinegar and water as it is a natural acid, If you are using bleach to clean the enclosure then do not put your pet snake in until the smell of bleach completely goes away, if you put your snake back before that it can cause the death of your snake.

Let the terrarium out in the sun to dry off, this kills any bacteria that you may have missed out on.

After cleaning the enclosure add new substrate and clean any decorations like the hide box and fake plants with water too.

Do spot clean after feeding your snake every week.

Clean the water bowl daily and add filtered water to avoid any sickness.

Diet of Dumerils boa.


Dumerils boas are carnivores their diet as a pet consists of eating, mice, hamsters, rabbits and chicks, and guinea pigs.

Boas from Dumeril are opportunistic feeders. They will consume practically everything in the wild, including live reptile food like animals, birds, and even lizards.

Dumeril’s boas will flourish in captivity on readily accessible rodents, rabbits, or birds. The majority of Dumeril’s boas will consume frozen or thawed prey.

Snakes do not need to be fed every day, the Dumerils boa needs to be fed after every two weeks, but this completely depends on the age of your snake. 

Young juveniles eat after every 14 to 2 days on the other hand an adult Dumerils boa eats after 25 to 28 days.

A hatchling should be fed every week.

Dumeril’s boas often consume food that is as broad as the snake’s widest region of its body. Smaller prey will satisfy the snake’s need, whereas larger prey may be regurgitated, which might make the snake uncomfortable and disturbed.

Although feeding every four weeks may sound cruel, Dumeril’s boas are renowned for having very sluggish metabolisms, therefore it is ideal for Dumeril’s.

In actuality, boas are prone to obesity. Try delivering smaller prey or feeding your snake less frequently if you find that it seems to be gaining weight on this system you can also take it to a vet to get proper advice, on whether it is obese or falling ill.

Modern understanding of snake psychology contends that our perception of “aggression” is incorrect; instead, snakes that have learned to associate the opening of the enclosure with food (as a result of infrequent handling) will lunge for the first object they see, assuming that it is food — with no malice intended toward the keeper’s hand.


Given that certain Dumeril’s boas are quite timid eaters, you might need to cover their enclosure or wait until the snake has done eating before leaving the room.

Always provide a dish of fresh water for your Dumeril’s boa (use filtered tap water or bottled spring water). Make careful to give Dumeril’s boas enough water because they gobble up big amounts of it at once.

The bowl of water should be large enough for the entire snake to soak in.


Usually, the snake tends to become weak, due to the lack of a nutritionist diet, in order to coop up with this deficiency, you should buy the prey of your pet Dumerils boa from a good pet store that is well aware of the diet requirement of snakes.

If your snake shows signs of lethargy and is becoming weaker you can give it vitamin D and calcium supplements, you can sprinkle powder form of these supplements over the food.

Replace your supplements after every 6 months.

Dumerils boas Breeding

In Madagascar, Dumeril’s ground boas are thought to mature sexually at around 18 months of age. 

The male and females of this species seem to reproduce most effectively when they are at least 4 and ideally 5 years old. Your female is doing well; at this age, a well-fed female would be around 5 to 6 feet long. She should be in top breeding shape after another year, in my opinion.

 The boa starts breeding during the month of March and continues till May.

The female will develop an egg bulge in her lower belly shortly after a successful mating. If a Dumeril’s ground boa female wants to remain healthy and give birth to a healthy young, she must continue to bask, ideally with overhead heat rather than a heating pad, do not handle your snake during this period time as she may become tired and restless.

During October start to lower the temperature of your enclosure, and keep it warm in February 

About five to seven months after mating, Dumeril’s ground boas give birth to six to twelve (sometimes as many as fifteen) 16 to 19-inch long babies. Immediately after molting, the newborns often begin eating and eating mice and rat pups. The infants are more stunning than the parents, they look adorable when born. Yes, Dumerils boa gives birth to young live snakes rather than laying eggs, this is rare in snakes as most snakes give birth to eggs.

Remove the males from the enclosure when you see the female snake’s skin shed, the male tends to attack females when they shed.
