That's pretty neat. I use boric acid for restoring rotted wood in my old 1800's house. It's been well known for a long time to stop insects. You can actually buy rods of the stuff to insert into rotting (or in danger of rotting) wooden beams (such as a beam in the foundation of an old house that gets too wet). When the wood gets wet the beam spreads and stops any further mold rot or insects (roaches, ants) from harming it. It's amazing stuff really. For other rotting pieces of wood you can create better mixtures with other easily available ingredients and sort of "paint" with the stuff.
