A gentleman gave me an outer cover and a deep that had nasty frames and a mouse nest that was inside. They box and lid had been sitting outside for 9 years. We dumped it out and I brought it home. After scraping the insides out and repainting it looks good. Except the inside looks old. After the paint set I brought it inside to finish curing. Just now walked in the room to see a wax moth larva crawling on the outside of the box. All that is in the spare room are newly made deeps, bottom boards, etc. Nothing from last year. Do they burrow in the wood? There are small holes in the inside. I thought they just made cocoons. What should I do?
