I've thought about building a nice treehouse retreat on my property. It'd be a sweet way to avoid increasing property taxes but still have a guest room, or a library. But I live where there are bark scorpions, meaning at night they're crawling all up and down those trees. Would have to be hella sealed.

Terrifying prospect

Maybe a sheet metal "band" around the trunk, several feet off the ground, would be enough to stop the scorpion from being able to make it to the treehouse. If the surface is smooth, the scorpion's tarsal shouldn't be able to find purchase.

Like a 12 to 18-inch wide band of smooth stainless steel or aluminum wrapped around the trunk.

Scrape x-inch bark off > apply metal mesh > 100% silicone sealant > butyl tape > wrapped aluminum > lock in with stainless steel hose clamps. Could even get a design lasered into the metal which might be cool.

Kind of like this from Reddit, but with those add'l steps: https://archive.is/yHYdj

The tree needs the bark to live. Peeling a ring of bark off around the tree is a well known to kill it.

Check your local permitting - there are often many “structures” that don’t trigger audits or permits but are still usable - outdoor kitchens, tents, etc. a treehouse may just be one option.
