This article is no longer being updated. Please use the new, comprehensive hermit crab food list!

Here follows a list of woods that can be used safely in a hermit crab environment.
These are non-toxic woods that won’t hurt them if eaten. This list, as all the others, is not in any way complete, and will be expanded as new information is received.
The list of unsafe woods follows the safe list. Fruit bearing trees are generally considered unsafe. (Not necessarily the fruit but wood, bark, leaves, seeds.)
Cholla or Choya wood
Cypress (swamp variety, taxodium species) **not a suitable substrate!
Evergreen of any kind (pine*, cedar, redwood, etc.)
Walnut (added 2/2018 after consulting with invertebrate veterinarians)
As an alternative to the pine half logs you see for sale for reptiles, Petco is now selling fake (as in non wood!) pine half logs. Joy!
*pine is currently being reviewed based on some feedback from experienced keepers. At this time we are keeping it on the unsafe list. If you choose to use it, do so at your own risk.
