How to Sterilize Wood for Reptiles

How to Sterilize Wood for Reptiles? I am guessing you are here because you recently had the experience below:

Every pet owner has had this experience:

Hey, I am going to stop by the pet store to pick up a climbing branch for my animal…

$35.00 for a stick?! HUH? 

Don’t you hate that? I know I do.



If you follow my blog or my YouTube videos you know that I am all about including natural features in your reptile’s enclosure to enrich their environment! Adding real branches to the enclosure is a great way to achieve that… but who wants to spend a bunch of money on something you can get outside for free!

Collect your Wood!

First you need to find some wood! Here are somethings to keep in mind:

  • Stay with hardwood trees (Oak, Ash, Maple, etc.), softwood trees contain sap that can be toxic to your animal. Likewise, stay away from any hardwood trees that seem to be very “sappy” for whatever reason.
  • Find an area that that is unlikely to have pesticides or chemicals sprayed. I.e. stay away from areas close to farmers fields (pesticides) or areas that may have been fogged for mosquitoes.
  • I look for trees that have recently fallen down. You don’t want something that has been decaying for a long period of time. I guess live trees would work fine as well.

Clean Up the Branches

Once you have found a suitable branch you need to “clean it up”. In other words, use a hand saw and sandpaper to smooth out any areas that could cause an injury for your animal.

Tools: Sandpaper and saw

I generally use a hand saw to remove any sharp leftovers from smaller branches.

Remove any loose bark. Then,  smooth out the entire branch, once with course sand paper and once with fine sandpaper.

It is perfectly okay to leave some rough edges here and there as some animals will use it to scratch and/or shed themselves against, but you should remove anything that feels sharp to your touch.

How to Sterilize Wood for Reptiles: Method #1

If your branch is small enough to fit inside your oven, than you can follow the directions for Method #1 (and consider yourself lucky)!

  1. Set your oven to 250°F
  2. Set yourself a 10 minute timer (reoccurring)
  3. Place your branch in the oven and bake for 2 hours
  4. Check it every 10 minutes to ensure there is no charring

The heat of the oven will slowly kill any bacteria and microbes found deep inside the tissue of the wood. Using a higher temperature DOES NOT make this process any faster and increases your chance of starting a fire! I promise… 2 hours is not that long, especially considering how long Method #2 takes!

Once 2 hours has surpassed, pull the branch out of the oven, wait for it to cool off and you are done!

How to Sterilize Wood for Reptiles: Method #2

If your branch is too large to fit inside your oven then you are stuck with Method #2! This method is equally effective, but takes much, much longer!

  1. Find a barrel, bin or tub large enough to contain your branch.
  2. Fill the tub with water, roughly keeping track of the volume of water you are using. I use a pail to fill my tub to keep track, i.e. 10 pails full of water is around 30 gallons total.

  3. Add bleach, using a ratio of 1/3 – 1/2 Cups of bleach for every gallon of water. Make sure you use regular bleach, do not use any products that have additives for laundry use, etc.

  4. Let the branch soak for a full 24 hours. If you have a portion of your branch that is above the surface of the water (like mine in the photo), change the orientation of the branch after 12 hours so the exposed portion is now submerged.

  5. After 24 hours, drain the tub of the bleach solution. You will notice the color of your branch will be lighter, the bleach pulls the tanins and pigments out of the wood. You now need to flush the wood to remove the bleach. Soak the wood for at least 48 hours in fresh water, change the water every 2-8 hours.

  6. After the wood has been flushed of the bleach you now need to let it dry. Wood will take anywhere from 3-5 days to dry depending on the size and the climate you live in. You MUST wait for the wood to dry out completely before adding it to your reptiles enclosure for one of two reasons: 1) If you add it to a humid environment it will never dry and likely grow mold or 2) if you add it to an arid environment it will spike the humidity of your enclosure for several days.

Adding natural wood to your enclosure can really enhance your animal’s environment and I highly recommend you do it!
