Ball pythons burrow for a handful of reasons, and most of them are completely normal. These snakes are naturally secretive animals that spend much of their time in rodent burrows and underground hideouts in the wild. In captivity, digging into substrate is usually your snake’s way of seeking security, regulating its body temperature, or responding to humidity levels. Occasionally, though, burrowing signals a problem worth fixing.
They’re Looking for a Better Hide
The most common reason a ball python burrows is that it doesn’t feel secure enough in its enclosure. Ball pythons are prey animals, and their instinct is to find a tight, enclosed space where they can’t be seen or approached from multiple directions. If your hides are too large, too open, or poorly positioned, your snake will try to create its own shelter by pushing under the substrate.
A proper hide should be low and wide, with only a single opening. Your snake should be able to coil up inside and touch the walls on most sides. Hatchlings do well with hides around 5 by 5 inches, while adults need something closer to 12 by 12 inches. A simple plastic shoe box with a hole cut in one side works perfectly. You need at least two hides: one on the warm side and one on the cool side. Without both, your snake is forced to choose between feeling safe and regulating its temperature, and it will often try to solve that problem by burrowing.
Temperature or Humidity Is Off
Burrowing is one of the ways ball pythons thermoregulate. If the surface temperature on the warm side is too hot, your snake may dig down to find a cooler layer of substrate. If the ambient temperature is too cool overall, it may burrow to insulate itself and conserve heat. Check your warm side surface temperature (it should sit around 88 to 92°F) and your cool side (around 76 to 80°F). A reliable digital thermometer with a probe, not the stick-on strip kind, gives you an accurate reading at substrate level where your snake actually lives.
Low humidity also drives burrowing. Ball pythons need 60 to 80% humidity, and deeper substrate layers hold moisture better than the surface. A snake that repeatedly pushes under its bedding may be trying to find a more humid microclimate, especially if it’s approaching a shed. If your snake is burrowing and you also notice cloudy eyes or dull skin, a humidity problem is the likely culprit.
Substrate That Encourages Digging
Some substrates practically invite burrowing, and that’s not a bad thing. Sphagnum moss, coconut fiber, and cypress mulch are all soft, loose materials that ball pythons naturally dig through. A DIY tropical mix of 40% organic topsoil, 40% coconut fiber, and 20% play sand holds humidity well and gives your snake something to explore. If your ball python is burrowing in a substrate like this but otherwise eating, shedding, and behaving normally, it’s likely just engaging in natural behavior.
Certain substrates, however, create problems. Aspen shavings don’t hold moisture and get moldy quickly in the humidity range ball pythons need. Pine and cedar shavings release oils that can cause neurological damage. Carefresh bedding is dusty and dries out too fast. If your snake is burrowing in one of these substrates, switching to a better option will improve its environment and may change the behavior.
Stress From the Enclosure Setup
There’s a persistent myth that ball pythons prefer small, cramped enclosures and that large tanks stress them out. This isn’t true. A small enclosure leads to poor muscle tone, obesity, and a lack of mental stimulation. What does stress ball pythons is an enclosure that feels exposed, one with too much open space and not enough cover. The fix isn’t a smaller tank. It’s more clutter: branches, cork bark, fake or live plants, leaf litter on the surface. A well-furnished 4-by-2-foot enclosure gives an adult ball python room to move while still feeling hidden.
New environments also trigger burrowing. If you recently brought your snake home, moved it to a new enclosure, or rearranged the setup, expect some digging and hiding for the first week or two. Give your snake time to settle before handling it.
Breeding Behavior in Females
If you have a female ball python, burrowing can be a sign of reproductive behavior. Gravid females often push all the bedding out from underneath them while coiled on the warm spot, creating a cleared “nest” area. This looks different from normal burrowing because the snake isn’t hiding under the substrate. She’s actively rearranging it.
Females that are ready to breed but haven’t mated may also display restless behavior: cruising the enclosure, wrapping around the water bowl, seeking the cool side more than usual, and going off food. These signs together point toward hormonal cycling rather than a husbandry issue.
Mites or Other Irritation
Burrowing alone isn’t a strong indicator of mites, but combined with other symptoms it’s worth investigating. Snake mites are tiny black dots visible around the eyes, ear pits, and vent area. Other signs include excessive rubbing against surfaces, prolonged soaking in the water bowl, lethargy, loss of appetite, and an ash-like dust on the scales (which is actually mite droppings). After handling, check your hands for small moving black specks. If you see any of these alongside the burrowing, a mite infestation is likely and needs treatment promptly.
How to Tell If It’s Normal
A ball python that burrows occasionally but still eats on schedule, sheds cleanly in one piece, and maintains a healthy body weight is almost certainly fine. The behavior becomes a concern when it’s paired with other changes: refusing meals for more than a few weeks (outside of normal winter fasting), incomplete sheds, visible weight loss, mouth gaping, or the mite symptoms described above.
Start by checking your temperatures and humidity with reliable digital instruments. Make sure both hides are appropriately sized and positioned. Add more visual barriers and surface cover if the enclosure looks sparse. These adjustments resolve the vast majority of excessive burrowing. If the behavior continues after your husbandry is dialed in, and especially if your snake stops eating or shows signs of illness, a reptile veterinarian can rule out underlying health issues.
