Best Substrate For Iguanas

Are you looking to set up your iguanas tank or pen, and you want to give it the best flooring possible?

Do you get lost looking at all the bedding options for reptiles?

When I first looked into my iguana habitat, I didn’t know what to look for in bedding.

And there were so many options out there, I felt frustrated.

After experimenting and researching, we here at Oddly Cute Pets came up with this list of the best substrates for iguanas.

The best substrate for iguanas needs to help retain heat, make clean up easier, be completely safe, and be available in larger purchase quantities. Our picks include the following:

Zoo Med Eco Earth Loose Coconut Fiber Substrate, 8 Quarts
  • Ideal for naturalistic terrarium type set-ups incorporating reptiles, amphibians or invertebrates.
  • Use it damp for tropical species as it naturally absorbs and breaks down odor and waste products.
  • All natural green "product"

What To Look For In The Best Iguana Bedding

In this section, we’ll help you realize what to look for in iguana substrate.

Use this section to educate yourself before digging into three reviews below.


There are two main types of substrate or bedding for all reptiles and pets.

These are divided into true substrate or flooring.

Use them in combination with each other or alone, but you need to know which kind you’re looking for.

A true substrate is made out of a natural material of some kind, such as coconut fiber, alfalfa, or cypress mulch.

These are natural materials found in the wild.

Often true substrate looks more natural and helps raise the humidity of the space.

True substrate also provides something for the iguana to dig in.

On the downside, the true substrate will be messier overall, and you’ll need to replace it regularly.

Flooring, on the other hand, is cleanable and usually lasts years.

The price may be higher (not always), but you may not need to buy more as often.

However, flooring materials such as plastic and vinyl don’t look as natural and won’t give the reptile anything to dig into.

Use a combination of the two if you so desire to get the best of both worlds.


This may seem obvious, but all substrates must be 100% safe and chemical-free.

When mulches or flooring get wet, there’s a chance any chemicals will bleed out into the ground and make the iguana sick.

Always buy mulch or other substrates from pet stores when using natural materials.

For flooring or “fake” bedding, pick things with no chemicals, lead, or other such things.

This is, of course, if you go shopping off our list.

The products we picked are all safe for iguanas and don’t have any chemical concerns.


Durability is a big concern.

Iguanas have a lot of flooring to cover (72 square feet (6.69 m²) as adults), and it will hurt your pocketbook to need to replace the bedding constantly.

Even true substrate can last months with minor replacement and daily spot cleaning.

You need to consider and decide how often you want to mess with the bedding.

For those on a strapped schedule, you may prefer to use artificial flooring, which just washes clean.

For those with time and dedication to making a natural pen, the effort of keeping up with true substrate will be fine.

Bacteria Resistant

While the humidity isn’t high in an iguana pen, there will still be moisture.

All substrate needs to have some level of bacteria-resistance to prevent mold and other nastiness from dropping.

Typically, true substrate materials will trap and prevent bacteria from spreading.

Fake flooring options wash clean but can attract mold quicker.

Either option works, but you need to consider this as you buy.

Helps With Cleanup

One of the main benefits of substrate is how it helps you clean up after the iguana’s droppings.

These lizards get big, and so do their droppings.

All the options on our list will help to a degree, but you need to think about how high of a priority this feature is for you.

Most natural substrates will clump up around the dropping, making it easier to scoop out.

Not all natural substrates perform equally in this regard.

Fake flooring options don’t trap droppings, but they are still easy to scoop and clean off.

The Eco Earth coconut fiber-based substrate is a good, medium-priced option for most iguana owners.

Zoo Med is a trusted company in reptile products, so you know the product will be of good quality.

It’s based on coconut fibers shred up.

Coconut is one of the safest materials for substrate out there.

It does a decent job of clumping up around droppings making clean up a little easier for you, the owner.

Coconut has self-sanitizing properties as well.

It will trap and even remove some bacteria from droppings.

Coconut is a good substrate to use when the iguanas are little and in their large pen.

It’s all-natural and “green.”

There are no chemicals used in making it, and the product is safe in the environment as well.

The Eco Earth is available in a condensed one pack of 8 quarts (7.57 l) of material.

Add some water and spread it out, and this pack will cover a lot more space.

It’s also available in a 3-pack of 8 quarts (7.57 l) of loose material (no need to add water) and a single 24 quart (ca. 23 l) loose pack.

This will cover a decent amount of space, but you’ll need to buy multiple packs as well, depending on the exact size of your iguana pen.

Pros For This Product:

  • Very natural look
  • Self-cleaning and easy cleanup of droppings
  • Affordable and good value
  • Large bags and multiple sizes

Cons For This Product:

  • May attract mites and bugs over time

Zoo Med Forest Floor Bedding

Zoo Med Forest Floor Bedding, 24 Quarts
  • 100% natural cypress mulch
  • All natural " Green" Product
  • Recommended terrarium substrate for many species of snakes, lizards, land turtles, tortoises, frogs, toads, salamanders, tarantulas
We earn a commission if you click this link and make a purchase at no additional cost to you.

Zoo Med’s Forest Floor option is another medium-priced bedding for those who would rather go for a more natural look and material.

This bedding is made from a natural cypress mulch.

Cypress mulch is more like what the iguana would find in the wild.

Cypress mulch does a good job of clumping around droppings, but it doesn’t have as much resistance to bacteria.

It’s important you still spot clean and remove droppings every day.

This product is available in 4 quarts (3.79 l), 8 quarts (7.57 l), and 8-liter bags.

Cypress mulch additionally does a nice job of retaining moisture.

If you keep your pen outside in a dry or arid environment, it’s difficult to keep the humidity up to the 50% relative humidity it needs to be.

With cypress mulch, it’s a little easier.

Also, cypress mulch is a naturally fun material for the iguana to dig into a little.

It also makes for a good cooling material to bury itself in when it gets hot.

Pros For This Product:

  • Good value for the amount
  • Absorbs moisture and clumps for easy cleanup
  • Natural and safe
  • Iguanas like to dig in it

Cons For This Product:

  • Material may be rough and “sharp.”

Oxbow Animal Health Eco-Straw

We earn a commission if you click this link and make a purchase at no additional cost to you.

This substrate is an affordable option perfect for young iguanas and full-grown ones alike.

It’s available in 20-pound bags and comes in small pellets.

This is one of the best substrates for any herbivore reptile, such as iguanas.

If accidentally ingested (as young iguanas sometimes do), it’s perfectly safe.

When it comes into contact with water, clumps right up, this makes for super simple clean-up, but it does make it a little of a pain if the water is spilled or you need to spray down the tank/pen.

It will also prevent mold and bacteria.

Overall, this is a popular option with iguana breeders.

Pros For This Product:

  • Large bags
  • Affordable pricing
  • Safe for accidental ingestion
  • Clumps up for easy cleaning

Cons For This Product:

  • Strong smell
  • Doesn’t look like a natural environment

Commonly Asked Questions

When talking about substrates, people often ask us these questions.

Here are brief answers to these questions. 

What does an iguana need in its cage? – An iguana will need heating lights, UVB lights, water dish, food dish, substrate, and furniture in its cage.

For more details, check out our iguana guide.

What plants can an iguana have in its cage? – Any plant non-toxic or poisonous is fine to keep in an iguana cage.

Small plants and taller tree-like plants will make a good addition.

Plants increase the humidity of the cage, which is hard to keep up in large pens as iguanas need.

They also increase the oxygenation and air cleanliness of the cage.

This is good for avoiding respiratory infections and mold.

A brief list of good plants includes:

  • Pothos
  • Ficus
  • Spider Plants
  • Bromeliads
  • Snake Plants
  • Orchids
  • Peperomia
  • African Violets

Do iguanas like to be petted? – Yes, to a certain extent.

Daily interaction and handling are important for building a bond with your pet and helping it feel comfortable with you and its surroundings.

Too much handling could irritate the iguana’s skin and stress it out.

We recommend daily handling of no more than 10-15 minutes each interaction.

Take your cues from the iguana’s behavior.

When it starts getting irritated, stop petting it.

And always wash your hands before and after handling.

How do I make my iguana tank humid? – Keeping an iguana tank humid enough is tricky business.

The space needed is so large the air is largely as humid as the room or outside weather around it.

However, there are some things to do to make the space more humid:

  • Use substrate
  • Keep a full water dish in the pen at all times
  • Keep live plants in the pen
  • Lightly spray down the pen 1-2 times per day (just watch for mold)
  • Use a humidifier

What do you keep an iguana in? – Many owners think a large tank will do for the iguanas’ whole life.

While this is possible, this shortens your pet’s life dramatically.

Iguanas need a lot of space to move and run around in.

Don’t forget; they get up to 5′ – 6′ feet (1.83 m) in length.

For babies and young iguanas under 18″ inches (45.72 cm), use a 20 gallon (75.71 l) tank.

As they get bigger, you need to build a pen, cage, or tank with at least 12′ feet (3.66 m) in length, 6′ feet (1.83 m) in width, and 6′ feet (1.83 m) in height.

If the cage is outside, make sure the walls go down 2′ feet (0.61 m) in the ground, if possible.

Iguanas can dig.

Chain Link fencing or glass walls are common for materials.
