My question isn’t regarding log cabins per se but maybe you know anyway.Just bought a cabin in Big Bear CA.I notice saw dust on a counter top,I clean it, it’s back shortly. I’ve read about a powderpost beetle, wonder if it could be that. But I haven’t seen any holes nor beetles.If not, any other suggestions?The ceilings are made of untreated wood & beams, not logs. Recently remodeled 3 yrs ago. If is the beetles, would they be gone by now. Typically not wet/rainy. Low humidity, can get sn
