Do Ball Pythons Need UVB?

Ball Pythons, scientifically known as Pythus Regius, are friendly companions known for their docile nature and coiled posture. Originating from West and Central Africa, these snakes are usually nocturnal hunters — munching on a diet rich in small mammals and birds. However, there are a lot of questions regarding the lighting requirements of these pets. Do ball pythons need UVB lighting for optimal growth? Will adding a UVB bulb make your snake healthier? 

Well, don’t worry. In this guide, we’ll walk you through the UVB lighting needs of ball pythons, along with their activity periods and more. Consequently, before you find ball pythons for sale, you’ll have an in-depth understanding of the right environment for your reptile friend. So, read on for the answers. 

Is UVB Needed for Bone Development?

The answer to “Do ball pythons need UVB?” isn’t as simple as it seems. So, before discussing the specific requirements, let’s look at the role of ultraviolet B lighting in reptiles in general. 

UVB (Ultraviolet B light) helps in the bone development of reptiles in several ways. While humans may get their UVB supplement from sunlight, reptiles housed indoors need an artificial source. This helps them produce vitamin D3, which aids in calcium absorption and bone formation. Without a sufficient UVB light source, reptiles may suffer bone softening and deformation, leading to metabolic bone diseases. 

Access to UVB light is especially important for diurnal species, who are active during the day, in order to regulate their vitamin D3 levels. 

These include:

  • Bearded dragons
  • Collared lizards
  • Carpet pythons
  • Box turtles, and more. 

UVB Requirements & Growth: Snakes vs Lizards

While both snakes and lizards are reptiles, the species have different UVB light needs. Out of the two, snakes comparatively require less UVB. They usually obtain their vitamin D3 supplement from their food, especially if they snack on whole prey (rodents and birds). However, some diurnal snake species may still appreciate UVB light exposure. 

On the other hand, lizards generally need more exposure to UVB light. Plus, some species, like bearded dragons and iguanas, bask in the sun to absorb UVB rays, which are used later to produce vitamin D3. So, if you decide to bring one such species home, remember to provide the right UVB light exposure, or your lovely pet may develop a metabolic bone disease. 

Ball Pythons: Natural Habitat & UVB Radiation

Growing to a maximum length of 72 inches, ball python snakes live in shrublands, open forests, and densely wooded areas. In the wild, these species spend most of their time seeking shelter under the ground. This means that you’ll generally see them leaving their burrows during dawn or dusk — hunting for prey. As a result, ball pythons portray a nocturnal behavior and aren’t heavily reliant on sunlight for their growth and development. 

The Scoop: Do Ball Pythons Need UVB

If you’re looking for the answer to “Do ball pythons need UVB lighting for survival?”, start by considering the species’s most active hours. As you’d expect, diurnal species, or those active during the day, are likely to rely on sunlight for their growth and nourishment. However, ball pythons aren’t quite the same. These friendly snakes are known for their nocturnal (night) and crepuscular (dusk and dawn) active hours, indicating that sunlight isn’t necessary for survival. 

Plus, unlike diurnal species that usually bask in the sun, ball pythons obtain warmth from ambient temperatures or residual ground heat. To put it briefly, sunlight exposure and basking are not a natural habitat for ball pythons. Hence, the species doesn’t necessitate ultraviolet B lighting for survival. 

However, if you’re wondering, “Do ball pythons need UVB for enhanced health?” the answer may be “yes.” Although not necessary for survival, exposure to UVA/UVB light may help boost the immune system of your slithery friend. In general, all reptiles, including ball pythons, may appreciate a bit of UVB supplementation here and there. 


Ball pythons, known to be a friendly and long-lived companion in the homes of many, come with specific care requirements. When it comes to their lighting and ultraviolet B requirements, these species have a nocturnal nature, meaning that they don’t rely on sunlight exposure. It means that even if your ball python receives little sunlight in its terrarium, it’ll still grow healthily. So, if you’re still wondering, ‘Do ball pythons need UVB?’ know that UVB exposure is not necessary for optimum health and growth.

However, just as good never hurts, setting a UVB supplement in your pet’s enclosure may have additional benefits. The python may have an improved circadian rhythm and a boosted immune system — contributing to a better lifestyle and surroundings. So, investing in a UVB light bulb might be wise before you search for your ball python pet!
