I have a 50ft Pecan tree that is very dead. The larger limbs are actually breaking off. It looks like the tree died from a beatle infestation, however they appear to be long gone. The wood is extremely dry and seems perfect for using in the smoker. My concern is that the tree died of an infestation is it okay to use in the smoker or is it better to play it safe and not bother? We are having a tree company come out to take the tree down before someone or something gets hurt, I would just like to use it if I can. Thanks for any advice you may have.
