Does My Corn Snake Need a Heat Lamp on Its Cage?


Do you own a pet corn snake? If so, you might be wondering whether it needs a heat lamp in its cage or not. Taking care of your snake’s habitat is crucial for its long-term well-being, and providing the right temperature is one of the most important aspects.

So, let’s address the question: Does your corn snake require a heat lamp?

The short answer is yes. Similar to other reptiles, corn snakes need supplemental heat when kept in captivity. There are various ways to provide this heat, such as using specialized heat lamps, mats, or tapes. However, the primary focus should be on creating the correct temperature range within the snake’s enclosure.

Now, let’s dive deeper into this topic!

Adding a Heat Lamp to Your Corn Snake Habitat

To answer the initial question, your corn snake definitely requires some form of supplemental heat in its cage. The objective is to establish a temperature range or “gradient” within the enclosure, and a heat lamp can help achieve this.

First, it’s important to understand that snakes, including corn snakes, are ectothermic creatures. Unlike humans, they cannot generate internal heat and depend on their surroundings to maintain suitable body temperatures.

In the wild, corn snakes can bask in the sun or warm themselves on rocks. However, in captivity, they lack access to natural sunlight and warm surfaces. This is where you come in as their caretaker.

To ensure your snake’s well-being, you must create an ideal temperature range within its cage. A heat lamp is a simple and effective method to achieve this. Place the lamp on one side of the cage and adjust the power to achieve the desired temperature.

So, what is the ideal temperature range for your corn snake? While experts may have varying opinions, most agree that a temperature range of approximately 70°F to 88°F (21 – 31 degrees Celsius) is suitable for corn snakes. The cooler side of the cage should not fall below 70°F, while the warmer or basking side should not exceed 88°F.

Personally, I recommend aiming for a temperature range of 72°F to 86°F (22°C to 30°C) for corn snakes. This seems to work well in practice.

By placing a heat lamp or mat on one side of the cage, you allow your corn snake to move between warmer and cooler areas to thermoregulate, just as it would in the wild. This mimics the natural behavior of snakes seeking shade or warmth as needed.

Observing your snake’s behavior is crucial in determining whether you need to adjust the temperature range. For instance, if your snake consistently stays on the cooler side, the warmer side may be too hot. In such cases, use a rheostat to lower the heat lamp’s output.

Conversely, if your snake rarely ventures to the cooler side, you might need to increase the ambient or background temperature. Finding the right balance may require some trial and error, but by following the general temperature guidelines, you will meet your corn snake’s heating needs.

The Difference Between UV and Heat Lamps

Understanding the distinction between heating and UV lightbulbs is also essential when caring for reptiles.

Incandescent and infrared heat lamps are designed solely to provide warmth to the snake’s enclosure and do not emit UVB rays. On the other hand, UV-spectrum light bulbs emit both UVA and UVB rays, while some multipurpose bulbs emit both heat and UVB rays.

Although corn snakes can survive without UVB lighting, they still benefit from its presence. UVB lighting enhances the aesthetic appeal of the habitat, brings out the snake’s vibrant colors, and helps establish a day and night cycle, which is essential for their overall health.

Several studies have shown the potential benefits of UVB lighting for captive snakes. Since snakes receive UVB exposure from the sun in their natural habitat, replicating this in captivity is worthwhile.

Other Ways to Warm the Cage

To summarize, a heat lamp is one of several methods you can use to provide supplemental heat for your corn snake. However, other options are available as well, such as heat mats or flexwatt tape placed under the cage. These methods allow heat to be applied from below, creating a temperature gradient within the enclosure.

When using heat mats or tape, exercise caution to prevent overheating, which can damage plastic or glass. Using a rheostat to control the output of these devices is recommended.

Alternatively, you can opt for a heat lamp if your corn snake’s cage has a screen lid. Simply place the incandescent or infrared bulb within a suitable dome or hood on one side of the enclosure. To monitor the temperature inside the cage, you can use an adhesive stick-on thermometer strip or a temperature gun for more accuracy.
