Yeah, I know. I had the same thought when I saw them originally with some bug damage. I went through the batch very carefully so they should be bug free. Also, it is fairly obvious when they aren't because they leave a little trail of bamboo dust and small pin holes...those one's got tossed into my grape vine and passion fruit terrace. I might straighten the remainder of them. The heat should kill any others off if they are there, I am just cautious to cut the bamboo because it seems like everyone likes different lengths.
