Preventing termites when using reclaimed wood or pallets

Mostly it's important to get the wood 8-12 inches above grade on a material that termites can't/wont eat. That way you can inspect the pile regularly and break down the tunnels they build to access your wood.

You could construct a platform out of palettes and top it with sheet of tin. The termites will eat the pallets of course but the sheet of metal will prevent them from getting into the wood pile.

You could just make sure to get regular termite inspections. I have used pallets before and haven't had a problem. I don't know if termites are more prevalent in certain areas than they are in others, though. Definitely be careful because termites are awful to take care of if you get them.

I have a lot of projects (inside the home)i would like to do with pallets. Have read many articles about choosing a pallet but never once did I find any thing about termites. How to treat the pallet so they can come in the home and not have to worry about termites/bugs like when companies that furniture and homes. Any suggestions or advice regarding this would be of great help

I am sealing my pallet containers with a termite prevention, and then painting them, so that termites, ants, and bees won't drill into the sides. If you want to keep the 'pallet look', find a termite prevention sealant like bora care, then stain, similarly to how you might treat a deck or other outside item built with untreated plywood.
