Bug infestation......

Thanks for the prompt feedback 'forboystoo'. After reading that first article, I'm much less inclined to bring in pallet wood into my home, regardless of whether it has been heat treated. It's true - you don't know where the pallets have been. And when you take into account the amount of time necessary to collect enough pallets to cover a wall, dismantle all those pallets, clean/sand all the individual boards down - the EverTrue option is a no-brainer! I wasn't familiar with that product, so thank you for mentioning it:)
