I recently installed a maple wood floor in a bedroom of my house. Before sanding and sealing I noticed the evidence of powderpost beetles, small holes and small piles of powdery sawdust. I obtained some Boracare and applied it to the floor per instructions. After completely drying, I sanded and sealed the floor. Within a few days, more holes and sawdust appeared. My question is; did the treatment of Boracare not work, or was it not thorough enough, or am I witnessing the end of the beetle life cycle that will now be stopped because of the Boracare? Do I have to sand and retreat the floor again?
Thank you for your help.
