Are you having a hard time keeping the humidity up in your crested gecko tank? Well, rest assured, you’re not alone. Even though it is technically springtime, it has still been a little dry here in Kentucky. This is why I thought it would be a perfect time to share my 5 ways on how I increase the humidity in my crested gecko tank.

First, make sure you have a good quality hygrometer so you get the most accurate reading. The one that we use is the Exo Terra Digital Thermometer and Hygrometer.*

Now, let’s talk real quick about what your crested gecko humidity requirements actually should be. During the day, the humidity in a crested gecko enclosure should be around 50%. At night, you should be misting their enclosure until their humidity reaches 100% and then let it dry out to 50% the next day and repeat. Spraying their cage is not only to increase the humidity in their tank, but to also to provide them a water source for drinking.

Okay, now that we have that out of the way – let’s get started!

1. Mist their cage

Wait, didn’t you already talk about misting their enclosure? Yes, I did! But if you are already following the basic requirements of misting and you STILL can’t get your gecko’s humidity levels right, you might need to mist some more. I’m not talking about drenching their tank, but if you notice their humidity is dropping below 50% during the day then giving it a little extra spritz in the morning might be all you need to do. Exo Terra makes a good quality mister that you can find on Amazon.*

2. Add moss

Another great method for increasing the humidity in your crested gecko tank is to add some moss! We use Zoo Med’s Terrarium Moss*and it is awesome! All you have to do is give it a good spray or soak and ring it out before putting it in their cage. Not only does it help the humidity stay up but it also makes their enclosure look more natural and is very aesthetically pleasing. If you notice the moss is starting to look a little dry, give it a quick spray and if it’s starting to turn brown, just replace it.

3. Change the substrate

If you’re still having a hard time getting your crested gecko humidity levels right, you might want to look at the substrate you’re using. But fret not! I can tell you what the best substrate to use in your crested gecko tank and it can be found in my Crested Gecko Enclosure Guide.

4. Put foil on top of their tank

If the humidity is dropping too rapidly and you’re finding you have to mist more than normal, it could be that the humidity is escaping too quickly through the top of their enclosure.

If your crested gecko tank has a screen mesh top (as most of ours do) then this option is a must. An extremely simple method to increase their humidity is to just put a sheet of aluminum foil over half of the screen mesh top and this will keep a lot of the humidity from escaping.

5. Use a reptile fogger

Finally, if you live in a really dry climate I would definitely recommend getting a reptile fogger! The best one we found on the market is the Zoo Med ReptiFogger.* Keep in mind it should be used in conjunction with misting their tank and not as a substitute but it really does make a huge difference in their humidity levels. Don’t get too crazy with it, though! Remember, their tank needs to dry out to around 50% during the day otherwise your gecko can get an upper respiratory infection.

Do you want to make sure your gecko’s humidity levels are staying consistent? Then you should definitely go check out my Reptile Humidity Tracker sheet on Etsy! Also, if you haven’t already I recommend reading my Crested Gecko Shedding FAQ’s: 5 Tips and Tricks to Help Prevent and Treat Stuck Shed.

And there you have it! I really hope this article has helped my fellow crested gecko keepers. As always, please feel free to share on Pinterest and don’t forget to follow me on Instagram for a daily dose of cuteness!
