Hi, I bought some slabs that were kiln dried but not perfectly. When I removed the bark there were quite many dried "caterpillars" that are white when alive. I have cleaned the surface of the edge and it seems safe but I'm worried because there are some insect holes going deeper into the wood and the center of the wood is probably not properly dried. I remember reading here that I can inject something into the holes to make sure that if something is inside it will die. Is there some substance that is available to buy in regular shops? I'm not in USA and I'm afraid that professional products wont be available.
