Wood For Vivariums
When thinking about wood for vivariums, can you use wood that you find outside for your bearded dragon or must you buy it from a store?
What Wood Is safe and What Is Not
In this post we investigate which woods are safe to use inside your reptile’s vivarium. We don’t intend to determine which woods you might make a vivarium out of and it should be noted that treated wood (or more precisely, lumber) is a totally different risk profile.
Which Why and How? – Wood for Vivariums
Are you are looking to add something different to your vivarium decor and don’t want the bog standard shop bought offerings?
Have you ever walked through a park or forest and seen a lovely branch or piece a of driftwood washed up on the beach and thought “is this a safe wood for lizards”?
Do you want to save yourself some money? Don’t mind spending some time foraging for that unusual wood feature or for an interesting climbing branch to make your lizards enclosure unique? But then you’re wondering if it’s a safe wood for vivariums.
This post will talk you though what types of wood to avoid and what wood is safe to use in a vivarium. We also go through how to prepare the wood so it is parasite and bacteria free.
Which wood should not be used In a Vivarium?
There are several types of wood that you should avoid using as decor in you beardies vivarium / tank.
Woods to avoid are:
- Coniferous or evergreen wood. (eg. Pine, Cedar, Douglas Fir, Camphor wood).
- Wood with thorns (eg. hawthorn, honey locust, Acacia trees).
- Wood that has been chemically treated.
Why are some woods not safe for your Lizard?
Some trees especially coniferous trees produce a thick sticky resin that oozes from the tree, it is thought to be a protective mechanism against damage, disease or infestation.
These trees also releases aromatic phenols, which are a volatile organic compound and are mildly acidic. It has been reported that short term high level exposure to these aromatic phenols have been known to cause respiratory irritation, skin lesions and burns. Exposure has also been known to cause muscle twitching and tremors which can easily be mistaken for MBD. In extreme cases exposure can cause seizures.
To put this in context low levels of synthesised phenols are used in our every day cleaning products including disinfectants and mouthwash.
Reports abound on the internet relating to sudden onset of dog seizures as a result of exposure to phenols from Eucalyptus oils and other essential oils around the home. Dogs have far more fresh air exposure than is likely inside your vivarium, even with excellent ventilation.
Cedar is the most toxic wood for your lizard and should be avoided at all costs. Pine, fir and eucalyptus do not have the same potency as cedar but all should be avoided and known safe options used instead.
Camphorwood also referred to as camphor tree or camphor laurel is also an evergreen which produces an oil that is extremely potent. And must be avoided.
It is also worth mentioning that cedar, pine, eucalyptus and camphor are becoming very popular as essential oils. The use of these oils around reptiles (and other pets) can have a detrimental effect on their health. Recent studies have shown that exposure to these oils can induce seizures and when the oils were removed the seizures stopped.
Any wood that has thorns should also be avoided. They have the potential to cause necessary injury to your lizard.
Chemically treated wood should also not be used in your lizard’s enclosure, simply because they have previously been treated with chemicals that may not be safe for reptiles.
Which wood is safe for use in a vivarium?
There are a wide array of wood that are safe to use in your vivarium. Below are just some examples this is not an exhaustive list.
- Tulip tree / Magnolia tree
- Crepe Myrtle
- Apple tree
- Dogwood (Cornus floridana)
Is there a difference between Bogwood and Driftwood?
The simple answer is YES…
Bog wood derives from hard wood trees that have spent hundreds to thousands of years submerged in either lakes, rivers , swamps or bogs. They are dark in colour due to the years of natural staining by organic matter. Bog wood is heavier and denser than driftwood.
Driftwood is essentially any tree, branch or piece of wood that has been drifted out to sea and washed upon a beach. It is usually light in its colour due to sun bleaching and natural weathering.
Why Is Driftwood and Bogwood safe?
Driftwood and bogwood will still need to be cleaned and sterilized before being used as decoration in a vivarium in order to make it safe. But, does it matter what type of wood it is? The answer is no – and this is because driftwood and bogwood have been separated from the living portion of the tree for so long that any phenols are long since evaporated or washed off.
It can be almost impossible to tell what type of wood (by eye at least) bogwood or driftwood is in any case. It may be from a Cedar or an Oak – you probably won’t know. But if it’s been in the bog or the ocean for a long time those nasty chemicals will be long gone and the wood safe for your bearded dragon.
Once the phenols and thorns are no longer a concern, the only issue left is parasites, bacteria or fungi. So, it is for this reason that we need to clean and sterilize bogwood or driftwood before using it.
How to Prepare Branches and Wood for Use In a Vivarium
Once you have sourced a branch or piece of wood that you want to used in your lizards vivarium, it will need to be made safe before use.
- Ensure the wood has no sharp edges (these can be sanded smooth) or holes where your reptile could get stuck. Avoid wood that it has started to rot.
- Remove any loose bits including bark and leaves. A wire or hard brush works well for this.
- Wash / soak the wood in 20% bleach solution this will help to remove any moss, lichen, fungus and bacteria that may be on the wood. Rinse thoroughly.
- You will then need to bake the wood in the oven for at least 30 minutes at 130 degrees or 260 Fahrenheit. This process will kill of any parasites and remaining bacteria. Allow to cool before handling.
- If your oven is not big enough for your chosen piece of wood, another option is to deep freeze the wood. Chest freezers are ideal for large branches. The down side to freezing is the process takes longer. Ideally you will want to leave the wood in deep freeze for at least a week if not longer to ensure it kills off all nasties. The wood will need to thaw and dry before use.
- Your piece of wood is now safe and ready to use as decor in your vivarium or tank.
Finding your own Basking rock
A good basking rock is often expensive to buy and will be the same as as many others. Why not make your beardies vivarium even more unique by adding a basking rock you have sourced your self!
The same principles apply to to rocks as they do for wood:
- Size is important – make sure it is not too large / high for the enclosure.
- No sharp edges – If your chosen rock has sharp or rough edges you will need to smooth them down with a file or rasp. This will avoid unnecessary injury to your beardie.
- It will need to be meticulously cleaned – Remove all dirt including any moss, fungus and lichen. Wash with a 20% bleach solution and rinse thoroughly.
- Sterilise your rock – It is not advisable to put rocks in the oven at high temperatures, there have been incidences of some types of rock exploding due to air pockets expanding within them. Instead soak the rock for a few hours in a diluted bleach solution and rinse thoroughly. This process will kill of any remaining parasites and remaining bacteria. You can also spray with reptile friendly antibacterial spray and leave to air dry.
- Placement of the basking rock – Take care when placing the basking rock in the enclosure, the rock must be sturdy and stable you don’t want the rock to fall over and injure your bearded dragon.
