Our 3 Favorite Snake Humidifiers (And Why They’re the Best!)

You need a snake habitat humidifier to keep your pet in optimal condition. Without one, it will become sick and eventually die. But with so many to choose from, it’s difficult picking the best.

Which are the top snake humidifiers? The Exo Terra Monsoon humidifier is effective and has good reviews. It sits outside the tank and pumps a fine mist inside through a hose. It’s a programmable humidifier, so it’s automatic. You will need a hygrometer, which are sold by Exo Terra and Inkbird. You could also use a handheld spray bottle.

Reptiles have specific temperature and humidity needs. These are based on what they would experience in their natural environment. To meet these requirements, you need a humidifier. If you don’t get one, your snake could become sick or aggressive.

Humidifier for Shedding in Snakes

One of the main reasons you need a humidifier is for shedding. When snakes shed, they like to shed all their skin in one go. They create a small hole near their nose and roll their skin back, revealing the new skin underneath.

They can’t do this if you keep the humidity too low. If the snake is too dry, their skin will come off in chunks. They will be forced to continually rub themselves against the glass or enrichment of their enclosure, and will become stressed.

Shedding problems cause more serious issues than stress, though. If the snake retains its eye caps, they will be unable to see. If they retain the skin on their tail, it can cut off circulation and cause the tissue to die. This can cause sepsis and death. A humidifier prevents this situation from arising.

Humidifier for Snake Eggs

If you plan on breeding snakes, a humidifier is necessary.

According to the Journal of Comparative Physiology B, unattended eggs become unviable because of humidity fluctuation. Snake eggs generally need between 90-100% humidity to hatch successfully. Less and some of the eggs won’t develop, and won’t hatch.

This is usually achieved in an egg box, inside an incubator. However, some snakes like to sit on their eggs, and some breeders like to let them. If that’s the case, you’ll need a humidifier to keep the humidity up.

Is Too Much Humidity Bad for Snakes?

Keeping the humidity too high can cause the build-up of bacteria. Because snake enclosures are warm, this encourages bacteria. Adding lots of moisture only encourages the bacteria to grow more.

In turn, this causes health issues for your snake. When the substrate becomes first damp, and then wet, it becomes uncomfortable for the snake to sit on. Their scales on their underside become soft. When bacteria enter the wound, it turns septic and can kill them.

Bacteria from excess humidity can also enter the snake’s respiratory system, and cause a respiratory infection.

So, keeping the humidity too high or too low makes your snake sick. But which humidifier should you get to correct that?

What’s the Best Snake Humidifier?

All humidifiers do the same thing: they release moisture periodically. As simple as that sounds, some do it better than others.

So, for example, the mist from one might be finer than from another. Some are automated, while some are manual. Others are more expensive because of their real or perceived quality.

Exo Terra Monsoon Solo High-Pressure Misting System

Exo Terra Monsoon Solo High Pressure Misting SystemExo Terra manufactures everything from misting systems to water bowls and enrichment. Their products are usually high quality and dependable.

The Exo Terra Misting System is programmable, which means you can tell it what to do, and leave it. It generates mist at scheduled intervals. You can change both the duration and the frequency of misting to control the humidity level.

When you first look at the humidifier, it seems complicated. It has two separate dials, each of which has lots of small lights to indicate its level. There are also lights to indicate whether it’s on or off, and whether the cycle is currently running. But once you’re used to it, it makes sense.

This system means you can set the humidifier to release a certain amount of moisture. If you do your research, and use a gauge to check how humid the enclosure is, you can set it and leave it.

This system benefits from being manufactured by Exo Terra, which is a trusted name. It sits outside the enclosure and releases fog into it through a hose. It can contain 0.4 gallons of water, and is a 5.5” by 5.5” by 6.5” cube. It only weighs 3lbs or so, but is heavier when full.

If you’re bothered about appearance, it isn’t exactly exciting. The motor casing on top of the tank is plain black. The water tank is a brown-gray color. You could decorate it in any way you like.

Advantages Disadvantages
Can be set and left, so no effort required once it’s set up correctly. Doesn’t sit inside the enclosure itself. As such, if the hose is faulty, then the whole system won’t work.
Releases very fine mist, which is perfect for a humidifier. Some reviews report that the motor inside can die, so keep an eye on it to ensure it works.
The programmable controls are more detailed than those of other foggers, which are basic dials.
A leak won’t necessarily damage the motor, because the motor is above the tank, which is sensible.

Evergreen Pet Supplies Reptile Humidifier/Fogger Large Tank

Evergreen Pet Supplies Reptile HumidifierLike the Exo Terra humidifier, Evergreen’s model sits outside the tank and feeds the fog inside through a hose. It consists of a motor with a dial, a large tank full of water, and a hose with suction cups.

The dial on this humidifier is more straightforward. If the Exo Terra looked complicated to you (and it is quite complicated), the Evergreen humidifier is for you. The dial goes from low to high.

Reviews for this product are slightly inferior to those for the Exo Terra, but are generally good. However, this product is sold at a much lower price, so this may be a trade-off you’re willing to make.

In terms of appearance, the Exo Terra is more of a cube. The Evergreen humidifier is more rounded, which you might prefer.

Advantages Disadvantages
Can be set and left, so no effort required once it’s set up correctly. Doesn’t sit inside the enclosure itself. If the hose is faulty, then the whole system won’t work.
Releases very fine mist, which is perfect for a humidifier. It has worse reviews than the Exo Terra model, so may not be as reliable.
Simple controls, perfect if you don’t like complicated machines. The water tank sits above the motor. In the event of a leak, the water would leak downwards and damage it.
Significantly cheaper than the Exo Terra Monsoon.

Conceptual Creations Mist’r Lizard Junior

Conceptual Creations Mist’r Lizard JuniorThe more you monitor your snake collection, the better. Automation is good in a way—an automated machine won’t ever forget to spray in the same way that a person can. But there’s a danger of too much automation, where you infrequently check on your pet, and health issues can develop.

If you’re an organized person and you like doing things yourself, you could use a spray bottle. But there’s a big difference between a basic spray bottle and a proper one. This one from
Conceptual Creations isn’t specifically manufactured for snakes, but it works well.

The bottle itself is only small at 3” by 11”, but it doesn’t need to be any bigger. It has a specially constructed, high-quality brass nozzle which doesn’t create droplets. It creates a nice, fine mist. The nozzle can be adjusted.

This is precisely what you need to raise humidity quickly. Big water droplets take time to evaporate and release moisture into the air. These droplets are so fine that it takes no time at all.

One thing to be aware of is that you shouldn’t spray your snake directly. As the mist evaporates quickly, it creates a cooling effect. Air temperature can drop between 10 and 30 degrees when you spray in an enclosed area. So, ensure that your snake has an effective heating system, too.

Advantages Disadvantages
Cheap, but does the job effectively. May have a chemical or plastic smell when it first arrives. Can be washed out to get rid of the smell.
No chance of it ever breaking if used carefully and correctly. Can’t be automated. You have to spray the enclosure yourself. You might forget.

Snake Enclosure Humidity Controllers

As well as a humidifier, you’ll need a humidity gauge. These can tell you how humid the enclosure is without you having to guess.

While people are good at gauging temperature, we aren’t so good at assessing humidity. And considering that none of these humidifiers automatically check the humidity for you, you need a purpose-built gauge.

Exo Terra Digital Hygrometer

Exo Terra Digital HygrometerThere are many available, but arguably the best is this Exo Terra digital hygrometer (hygrometer means humidity gauge). It comes with a screen, and attached to it is a tiny gauge with a suction cup. This suction cup sticks to the wall of the enclosure.

The screen tells you the humidity in percentage in big, block numbers—easy to understand. Now you can see whether it’s too humid or not humid enough.

If you have a programmable humidifier, you can adjust the program so that the humidity stays perfectly within range at all times.

However, it’s up to you to control the humidity, as this gauge doesn’t do it for you. It only tells you what the humidity is. It doesn’t adjust it for you.

Advantages Disadvantages
Cheap enough that it won’t break the bank. Basic as it only gauges humidity, while other sensors check temperature too.
Reviews indicate that it does the job well enough. Simple design that you might find boring.
Big, easy to read numbers.
Small enough that it can be used with any tank.

Inkbird AC 110V Pre-Wired Outlet Humidity Controller IHC-200

Inkbird AC 110V Pre-Wired Outlet Humidity Controller IHC-200This humidity controller from Inkbird does many things. It’s the most useful thing on our list, as it allows you to calibrate the humidity of your snake’s enclosure exactly. And, for the price, it’s definitely worth your consideration.

It works as a hygrometer. Like the Exo Terra example, a small sensor sits in your snake’s enclosure. The screen will tell you precisely what humidity the enclosure is at. According to the product’s specifications, it’s accurate to within 3% or so, which is close enough.

This humidity controller comes with two outlets for you to plug a humidifier or dehumidifier in. You then specify the humidity range your snake needs: say, between 50 and 60%. When it detects the humidity is too low, it turns on the humidifier.

To be clear, this controller doesn’t come with a humidifier or dehumidifier. You need to purchase these separately. But once set up correctly, you can be sure that the humidity will remain correct.

Advantages Disadvantages
Has an alarm that goes off if the humidity gets too high or too low. Doesn’t come with a humidifier, so buying one plus a humidifier is expensive.
Automatically corrects the humidity to keep it within the levels you’ve set.

Alternatives to Snake Enclosure Humidifiers

The options above aren’t perfect. If you are going to spray the enclosure manually, you could forget, or spray unevenly. And automatic misters can be expensive.

If you can’t buy one of the options above for any reason, consider offering a large water bowl. These naturally give off moisture throughout the day through evaporation.

They serve other purposes, too. If the snake needs to bathe to loosen their skin before shedding, they can. They may also drink occasionally from the bowl (although they would prefer running water).

If you do want to offer your snake a water bowl, pick one that meets the following specifications:

  • The snake can get in and out of it on their own.
  • The snake can’t tip the bowl over accidentally (i.e., it should be sturdy).
  • The bowl should contain enough water for your snake to submerge itself, but no more.
  • The bowl should be a material that’s easy to clean, like metal.

You might find that a water bowl releases enough moisture that you don’t need a mister. This may be the case with corn snakes, which don’t need a lot of humidity anyway.

How to Use a Snake Humidifier

Snake humidifiers are easy to use. Set them up in the corner of the enclosure, somewhere that the snake won’t be sitting. You want the fog/mist to move gradually across the enclosure, which allows your snake to hide if they don’t want to cool down.

Then, program the humidifier so that it releases the optimal amount of moisture. Keep an eye on it to ensure it doesn’t creep too high or too low.

What Is the Right Humidity Level for Snakes?

The exact humidity level required for snakes varies by species. That’s because snakes are a highly successful species, and live in many habitats across the world. Some live in dry grasslands and deserts, so don’t need any humidity.

Others live in rainforests. It’s these snakes that require the highest humidity level. Burmese pythons and carpet pythons require humidity of 60-65% because that’s what they find in their habitat.

Ball pythons require lower humidity. They live in warm areas close to the equator, in grasslands and savannas. This area is less humid than the rainforest, so ball pythons only need 55-60% humidity.

Corn snakes need a different level of humidity again. They live in grasslands in cooler parts of the world, which are less humid. They only need 40-50% humidity.

There is no one level of humidity required for snakes. The exact level depends on the snake species.
