This is copied from the RCW that applies to baiting and hound hunting:
(d) As used in this subsection, "bait" means a substance placed, exposed, deposited, distributed, scattered, or otherwise used for the purpose of attracting black bears to an area where one or more persons hunt or intend to hunt them.
Having read that, I would think that a well-established orchard would be like any other food source, for example a berry patch. I could see where a dumped pile of apples would be considered contrary to the law though. With that in mind, I would not hesitate to tip one of those flat-footed critters over if I caught it in my orchard.
But, it sounds like you have some concerns over possible issues with a neighbor or two, so in that case, I would be inclined to contact the game dept and ask, then go from there. I would inquire by email, so then I have a time & dated record of my inquiry and any response...just in case.
