Humidity is the amount of water vapor in the air. High humidity can cause respiratory infections and fungal infections in reptiles. Too low humidity can result in dehydration.

Keep humidity at 50-70%. To do this:

  1. Mist your pet’s cage daily with dechlorinated tap water or well water, and replace the paper towels or newspaper daily.
  2. Use a reptile fogger to increase humidity in your home. Just mist the cage lightly with dechlorinated water before turning on the fogger and turn off any fans while you are using it to avoid moving dry air around.
  3. Soak your pet in lukewarm water for 15 minutes daily. Reptiles can absorb some of their hydration this way without drinking at all. Anytime you handle your reptile, do this as well so you don’t stress them out.
  4. Get a hygrometer to measure the humidity in your home, and keep it near your pet’s cage.
  5. Buy an automatic mister for your pet’s terrarium. These are especially useful during times when you will be away from home or at night when you won’t be misting the terrarium yourself.
  6. Use a dehumidifier or air conditioner to maintain humidity, or put your reptile’s cage in front of a humidifier. But make sure that your pet’s cage is not getting wet and rotten from water droplets falling on it.
  7. Feed your reptile only once daily, at night after the lights are off. This will help keep their metabolism low and conserve water in their bodies, which will result in fewer respiratory infections.
  8. Use heat lamps instead of heating pads or rocks to provide your pet with warmth. reptiles metabolize better when they are slightly cooler than you are.
  9. Use a smaller water bowl in the terrarium, and refill it only when it is almost completely dry. This will help you monitor how often your reptile is drinking.
  10. Use a hydrometer or refractometer to measure your pet’s specific gravity (s.g.), which should be between 1.008 and 1.014 at 70 degrees F. A higher s.g. means your pet is dehydrated, and a lower s.g. means they are drinking too much water and their body fluids could become diluted to the point of organ failure.
  11. Give your reptile calcium powder or multivitamins daily for overall good health, unless they have special dietary needs that require a different supplement.
  12. Maintain a temperature gradient by having a warm side and a cool side in the terrarium, with a basking spot available at one end that is between 95-105 degrees F. This will help your pet regulate their body temperature so they won’t have to use as much energy for digestion, which conserves water.

What Does Humidity Do for Reptiles?

Now that you know how to keep humidity in a reptile tank, what does it do for reptiles?

Their skin is made up of scales that are similar to shingles on a roof or bladeless razor blades. They are flat and lay down smooth.

If you have ever worn vinyl before, then you know what happens when the air is dry. When it is dry, the blades/shingles/scales stand up and make your skin feel rough.

When a snake sheds its skin, these scales are in this “stressed” position. They can not lay down until wetted with water. Exposure to light will cause them to dehydrate.

When humidity is too low, the skins can not lay down properly and this leaves microscopic spaces in between the scales, which are perfect places for bacteria or fungus to grow. This can affect your snake’s health by causing respiratory infections.

How Do I Increase Humidity in My Snake Tank?

You may have heard the term ‘humidity’ being mentioned in some snake forums or perhaps you are confused whether you should increase or decrease it for your snake species to be healthy.

I actually faced the same dilemma years ago, so let me tell you what I found out about humidity and snakes.

There are various ways to increase humidity.

However, the most common way is to spray water on the sides of your tanks so they will evaporate and provide moisture into the air. A hygrometer measures this evaporation by calculating how much water is in the air at any given time.

Now that I have told you about humidity, let me give some general recommendations for different snake species.

1. Ball Pythons

Ball pythons (Python regius) do not need high humidity at all. In fact, it is best kept between 40-70%.

However, there are some who recommend increasing the humidity to 60% when your ball python has shed.

This is because they like their cages dry and most people use paper towel substrate. The substrate absorbs liquid very well, so it is important to keep your cage dry or you will get a bacterial infection otherwise.

2. Burmese Pythons

Burmese pythons do best at 75% humidity and lower after feeding (from 70-75%).

The air can be quite humid with this species (80-100% humidity). If you notice that your burm has a respiratory infection, decrease the humidity to 60% and increase it again so your snake can clear its lungs.

3. Corn Snakes

Corn snakes (Elaphe guttata) do best at 50-60%.

However, if your corn snake does shed, you may want to decrease the humidity to 40% for about 24 hours.

This species will readily drink from a water bowl or even a wet paper towel.

Ball pythons and Burmese pythons do not drink from standing water, so you don’t have to worry about a water dish. If your snake does not seem interested in the standing water, you can soak it in a bucket of lukewarm water for 20 minutes.

4. Kingsnakes (Lampropeltis) and Milk Snakes (Lampropeltis Triangulum)

Kingsnakes (Lampropeltis) and milk snakes (Lampropeltis triangulum) do well at 60-75%.

The humidity can be quite high with this species. I often get over 90% humidity in their tanks. Do not worry about the substrate getting wet either. It is fine.

The substrate should be damp, but please do not soak it.

5. Reticulated Pythons

Reticulated pythons (Python reticulatus) need a humidity of 60-70% and need a water bowl. You may have to increase the humidity to 80% if your snake is going through a shed.

Desert species such as sand boas, dwarf boas (Boa), and king snakes do not need high humidity like other popular species. It is best to keep it between 40-60%.

Snakes are fascinating creatures. They are beautiful and I hope this has helped you understand them a little better.

How to Keep the Frog Tank Humid?

Frogs are amphibians, which have moist skin or mucous membranes.

Thus, it is important that you learn how to make your frog tank humid.

A common mistake made by frog owners is to believe that the frog’s habitat should be dry and not humid.

This is wrong because frogs are rather comfortable in humid conditions. Remember that you can use these simple tips to keep the frog tank humid.

1. Use a Water Dish With Fresh, Clean Water

Frogs need to have access to fresh, clean water at all times. Leaving your pet frogs without water for more than two days will be clearly dangerous for their health. So it is important that you always keep the water dish filled with fresh, clean water.

2. Clean Your Frog’s Tank Regularly

Frogs are easy to maintain because they are used to living in moist habitats all the time.

While it may be incredibly easy for you to clean their tanks, it is important that you do so by removing all old water and replacing it with a fresh, clean one.

3. Use a Humidifier for the Cold Days

Your frog’s habitat needs to have high humidity during the winter season or at other times when air conditioning is on.

You can place your tank near a heater or use a humidifier inside the room to make sure that your pet frogs are comfortable.

4. Place a Cover on Top of Your Tank

You can put a lid or a cover on the top of your frog tank to prevent it from getting too much light and heat.

Your pet frogs will be more comfortable if you do so.

You should make sure that you leave some openings for air circulation, though. Otherwise, they could get suffocated.

5. Place Rock or Wood Over the Substrate

You can also adjust humidity with how you lay out your frog’s tank.

Make sure that you put rocks and wood here and there in the tank to keep it humid.

You should not use sand because it is too dry for your pet frogs. Remember that live plants will help supply humidity for your pet frogs as well.

6. Increase Humidity by Misting and Spraying

You can also adjust the humidity of the frog tank depending on how you spray and mist your pet frogs with clean water throughout the day or whenever necessary.

Remember that while this is not a good way to maintain the right amount of humidity in your frog’s tank, it is a good way to adjust it.

7. Never Use Chemicals

Never place chemical-based items in your frog tank because they would make the environment toxic for your pet frogs.

Remember that the focus of keeping your frog’s tank humid is to keep the peat moss moist but not wet all the time.

Just remember how to keep the frog tank humid and that you need to keep the substrate moist, not wet all the time.

How To Keep Humidity In Reptile Tank

What Are Humidifiers for Reptiles?

Some reptiles can be a bit more difficult to maintain. They need the right temperature, humidity, and lighting.

This is especially true for turtles, geckos, or iguanas that live outside in the wild.

There are many ways to provide your reptile with the proper environment but one of them is using a humidifier for reptiles. Reptile humidifiers are devices that supply the right amount of humidity to your pet’s habitat.

They are usually combined with heating pads or lamps in order to provide additional heat for the animal.

A reptile humidifier comes in many forms, from a misting bottle to an actual device that works like a regular household humidifier. The latter is able to heat up, too, which is another important factor for reptiles that live outside in the wild.

You can also get reptile lamps that will provide warmth and humidity for your pet’s home all at once.

What Is the Difference Between Humidifiers and Vaporizers?

There are two types of humidifiers for reptiles: humidifiers and vaporizers.

A humidifier supplies additional humidity to the air while a vaporizer produces steam that is able to add humidity to your pet’s habitat.

How Do Humidifiers for Reptiles Work?

Reptile humidifiers usually require regular maintenance in order to work properly and provide the right amount of humidity.

The device has to be filled with water or turned on for a few hours in order to get the job done. There is also a timer that automatically turns it off after a certain number of hours, depending on your needs.

Humidifiers for reptiles come with either filters or wicks that absorb the water and release it into the air.

They have to be replaced from time to time in order for the humidifier to work properly. The device will stop releasing humidity when a filter or a wick has dried up and needs replacement.

Most reptile humidifiers require electricity but there are some that run on batteries, which is especially helpful if you’re going away for a week or two.

Reptile humidifiers are made to be used with certain types of reptiles, but you should always check that yours is compatible before making your purchase.

What Are Other Uses of Humidifiers for Reptiles?

There are many ways to use a reptile humidifier in order to provide the proper environment for your pet.

You can put it under a lamp or under the basking spot of your pet.

It can provide enough humidity for you to be able to spray directly into its terrarium, or it can serve as part of a bigger system that includes heat lamps and other devices designed for reptiles.
