Thanks so much for the feedback. I've been looking into building a solar kiln, unfortunately I haven't had the time to do so quite yet. Everything looked pretty clean coming in. I have some maple in a different location that unfortunately became infested with powder post beetles and I can see the holes with frass. There are definitely no termites or carpenter ants etc.. Insect wise I'm assuming this is what you were referring to... is there anything else I should be aware of? I am located in CT.
