The Real Kill product.  Surely there is a mainland equivalent to this.  Its about 8 bucks at the grocery store.

   

I might add that anytime I see any powder pop up on my shelves or desk I zap the area with this stuff and never see it again.

There's a backstory to my powder post shelving. I worked in a cabinet shop for about 2 years recently. Boss had bought a load of 3/4 veneered cabinet plywood from a vendor on the main island that was unknowingly infected with powder post. He sent out a lot of cabinets using that stuff, probably 40-50 sheets worth, and made a lot of people unhappy that he could not cure/replace the work. When I started working there were still a few sheets of that ply hanging around. He was all too happy to make me a deal too good to pass up to carry it home. So I did a lot of shelving work with it. I knew what I was getting in to and I think finally, years later, I have found the magic cure.
