I also bought a oaxacan lion at Crizmac. Same thing happened to mine. I
put it in the freezer for 2 weeks (overly cautious, I suppose) and it did
the trick...no more sawdust piles.
>Oh, be careful! I'd gotten a sculpture from Mexico and had the same experience. I called my pest control company and they told me there's a special type of wood borer in Mexico that once inside your house can cause irreparable damage to wood floors and furniture. They advised that I put the sculpture in a double plastic bag and throw it away, as they knew no effective form of killing the little devils. Maybe I got rid of a perfectly fine piece of art, but I still have my furniture intact.
