Corn snakes are one of the most popular captive reptiles, owned by thousands of enthusiasts around the world. As a corn snake owner, it's your responsibility to keep your snake comfortable, which means proper housing, temperatures, and diet. Achieving the right temperatures in the enclosure is essential to your snake’s overall health and a heating pad is one of the top choices for reptile owners, helping to radiate heat into the enclosure, creating a hot spot that enables your snake to regulate its temperature with ease.

Corn Snake Temperature Requirements

Corn snakes are cold-blooded and therefore they rely on their environment to provide the heat their bodies need to metabolize. You should provide three temperatures in the enclosure working from one side to the other, this enables your snake to move between areas comfortably.

  • Basking Surface - 90°F (32°C)
  • Ambient / Air Temperature - 78-82°F (25-27°C)
  • Cool side - 75°F (23-24°C)

Nighttime temperatures can drop to 68°F (20°C) at night. Depending on your climate, you may not need to provide heat at night. If you do, ensure you use your heat mat with thermostat, providing a comfortable night time temperature for your reptile pet.

Best Heat Source for Corn Snakes - Heating Pads vs Heat Lamps

There are two common heating sources used by corn snake owners:

  • Heating Pad (or heat mat or under tank heater)
  • Heating Lamp

Heating Pads

Pros

  • Great for corn snakes that seek ground heat
  • Can be used in a variety of setups
  • Gives heat to the belly to assist with metabolism

Cons

  • Can cause burns if not used with a thermostat
  • Can stop working without you noticing, which is why you must use a thermometer to monitor your temperature regularly
  • Can crack glass tanks if not installed properly

Never use a heating pad without a good thermostat, such as the BN-LINK Digital Heat Mat Thermostat Controller. This offers effortless heating with a three-button interface to help you choose your temperature settings with confidence. It offers digital display, Fahrenheit and Celsius and easy power indicator lights. It has a very rugged construction with a six-feet temperature probe and is safe and reliable. This thermostat controls temperatures ranging from 40-108°F, the temperature display range is 32 -140°F.

Heat Lamps

Pros

  • Affordable
  • Available in most pet shops
  • Wide variety of wattage strengths available

Cons

  • Dry the air, removing any humidity in the enclosure
  • Must use with a thermostat to make it safe to use
  • Doesn't reach inside hides
  • Replace often
  • Night temperatures drop considerably when turned off

Considerations When Buying a Corn Snake Heating Pad

The size of the pad is important. Remember you want it to cover one third of the floor on the underside of your enclosure to achieve a thermal gradient. 

You may be wondering what wattage your heat mat should be. The wattage depends on the heating pad size.

General rule of thumb:

Tank Size

Heat Pad Size

Heat Pad Wattage

10 gallon

4 x 5 inch (10 x 13 cm)

4 W

10 - 20 gallon

6 x 8 inch (15 x 20 cm)

8 W

30 - 40 gallon

8 x 12 inch (20 x 30 cm)

16 W

50 - 60 gallon

8 x 18 inch (20 x 45 cm)

24 W

Corn Snake Heating Pad Setup

Glass Enclosures

  • Place the heat mat under the side of the enclosure where you want to create your basking surface.
  • Plug heat mat into thermostat and stick probe on the floor, to the center of the heat mat area. Make sure the probe can not be moved by your snake.
  • Set thermostat with minimum and maximum temperatures to ensure the safety and health of your snake.
  • Place the probe of your thermometer on the heat mat for easy monitoring.

NOTE: You can consider placing the thermostat probe between the base of the tank and the heat mat, on the outside. This is often used by breeders that use small plastic tubs to breed their corn snakes

Wooden Enclosures

  • Place the heat mat inside the wood enclosure on the side you want to create your basking surface. This is because the wood stops the radiation of heat.
  • Once you have plugged in your thermostat, lay a layer of shelf liner and then your substrate, reducing the risk of your snake coming in direct contact with the heat pad.
  • Set your thermostat temperatures and set your thermometer, with the probe glued to the center of the pad to provide accurate temperatures for easy monitoring.

NOTE: For both glass and wooden setup, only put a thin layer of substrate over the heat mat, as the substrate can prevent the radiation of heat.

How to Use a Heating Pad Safely

The first and foremost thing you need to know when it comes to heat pad safety is to always use a thermostat. This cannot be stressed enough. Without a thermostat, the heat pad cannot regulate properly, this means it can overheat and injure your pet.

Ensure you place the probe on top of the heat mat to measure the temperature. There is no point in putting the probe away from the mat. You want to get an accurate reading. Use a thermostat and then a thermometer to ensure that you can accurately monitor temperature at all times.

Regularly monitor temperatures within the terrarium using your thermometer to ensure your heat mat is working properly and safely.

Glass Tank

Place the heat pad on the outside of glass terrariums to reduce any direct contact. Placing the heating pad on the outside of a glass terrarium helps with heat radiation, helping you create a comfortable basking surface for your corn snake.

Wooden Tank

In addition to this, if you have a wood vivarium, you are going to need to place your heating pad on the inside of the terrarium, which is why you want to make it safe for your corn snake and reduce the risk of it coming into direct contact with the pad. Use a layer of shelf liner to create a barrier and reduce the risk of your pet coming into contact with the pad and getting burned.

It's also never recommended that you put substrate directly onto the heat pad. It is not safe and its' high risk. Therefore, even when you have your heat pad on the outside of the terrarium, using some shelf liner and then your substrate can prove useful.

Raised Bottom

raised bottom vs no raised bottom

To reduce the risk of fire and overheating, you want to ensure you leave a gap between the heat mat and the surface to allow for adequate airflow. If your enclosure isn't already raised, then use small rubber feet to lift it a couple of centimeters. The same applies if your enclosure doesn't have a gap in the base for the heat pad cord. Make a hole to reduce the risk of the tank pushing down and squeezing the cord, which increases the risk of fire in the home.

Conclusion

The heat pad is definitely the most popular heating source for corn snakes. It offers a basking surface where your snake can regulate its temperature and soak up the belly heat it needs to ensure good overall health. Remember to always use a thermostat to manage the heat pad temperatures, along with a digital thermometer and temperature gun for accurate monitoring to ensure your corn snake remains happy and healthy.
