They both eat wood. You should get an exterminator and get rid of the item that is being affected even if expensive or the problem will return. There is no way the poison will reach everywhere in a door or piece offirniture you would have to dip it in the poison and wait for it to completely soak into the wood. More practical to get rid of the item.
By the way check books, picture books and other paper and cardboard items. They love the glue and paper material not just wood.
