I rescued several old doors (100+ years old?) from a farm house that has been abandoned for over 50 years. I want to use them to add an antique flair to my house, but they definitely have holes from some kind of small wood boring beetle. I have read that the best way to treat the problem is to heat them to 130 degrees F but I'm not sure how to go about doing that. Any suggestions? How worried do I need to be about this? I don't mind that these old doors have holes in them because I like the character, but I certainly don't want to bring an infestation into my house.
