Do California Kingsnakes Need UVB Light?

Do California kingsnakes need UVB light?

When bringing home your first pet snakes, there is a myriad important thing to know in order to keep your snake healthy. California Kingsnakes, for example, are cold-blooded and need temperate options to control their internal body temperature. But do California kingsnakes need UVB lights as well?

California King Snakes do not require a UVB light in their containment spaces, however, new research suggests UVB light (when provided at the correct temperatures and allotted amount of time) may provide some health benefits for snakes. These benefits include: boosted immune system, healthier skin, and improved vision (specifically when it comes to color.)

Additionally, snakes require adequate light and temperature lamps to regulate their environment so that it is always between a maximum of 85 degrees F (on the warmer side) and a minimum of 72 degrees F (on the cooler side). You can provide your snake with a UVB light, but be sure it is high quality and one you can regulate so that you don’t overheat your pet snake.

How California Kingsnakes Get UVB Light In the Wild

The reason most snake forums, blogs, and books suggest it is unnecessary to provide your pet snake with a UV lamp is that, largely, most pet snakes are nocturnal. Meaning, they would not often be out in the sun during the day, as they do most of their wandering in the moonlight hours.

However, some snakes may benefit from the exposure to some occasional UVB light, as the intake of Vitamin D3 helps snakes to better absorb calcium, which they need to be healthy. Some would argue that calcium is ingested in their food, and therefore rendering the vitamin D3 unnecessary.

As a California kingsnake owner, the goal should always be to replicate a wild snake’s environment as much as possible, while doing so safely. And luckily, research from the Journal of Zoo and Aquarium Research has suggested it is safe, and likely beneficial, for pet snakes to receive small amounts of UV light depending on the breed. California Kingsnakes, which are cold-blooded, should receive a very small amount, a UVI: gradient scale of 0-.07.

Why UVB Light and Temperature Are Important for California Kingsnakes

Like in the wild, snakes enjoy different temperatures, which is why it is recommended you provide two different sides to your snake’s enclosure: a cooler side and a warmer side. Many snakes, especially cold-blooded snakes like that of the California kingsnakes, can regulate their own internal body temperature by moving to the warmer or cooler side as needed.

You never want to keep your snakes in a cage that is one single temperature, and to maintain their optimum health you want to be sure the temperature light you provide is high-quality, and accurate so you aren’t accidentally roasting or freezing your snake friend.

In the same way that humans can get sick from being exposed to improper temperatures, snakes can experience a variety of different maladies if their environment is not conducive to their bodies and needs. Some of the more common issues that arise from not providing proper temperatures are respiratory infections (like pneumonia or colds), infectious diseases, or parasites.

Must-Have Temperature & Light Regulating Items for California Kingsnake Enclosures

Now that you know how crucial it is to provide two different temperatures (warmer and cooler) on different sides of your snake’s enclosure, it is time to get familiar with the different gadgets and gizmos that can help regulate said temperatures in an accurate and easy to use ways.

When you do this, it will effectively filter out up to 50% of the UVB wavelengths, which I the ideal amount.

This light is both UVB (10%) and UVA (30%). These low levels of UV, further dissipated by the screen, will be the right amount to help prevent your snake from illness and increase their immune system, activity level, appetite, etc. The fluorescence also helps to illuminate the terrarium and thereby aids in creating a natural day/night photoperiod.

As previously mentioned, it should always be a primary goal to make an environment as real and as lifelike as possible for your enclosed pet reptile.

Providing options for your pet California kingsnake is critical to their overall health and wellbeing. They might not need UVB lights but most people would say that they are still beneficial.
