HELP!!! Bitsy will NOT stop chewing on wood! I think she thinks it is a new food group

My kitchen chairs, the headboard on the bed, the coffee tables......if it's wood she is chewing, chewing, chewing!!! She is ruining things. I scold her and move her away from what she is chewing on, but as soon as I turn my back...you guessed it!
munch munch munch. What can I do????
