Barnet lost leading scorer John O'Flynn to injury in the 62nd minute but, even with him on the pitch, they did not muster a single clear opening.
Hendon said: "I'm disappointed with the result because the first two goals were mistakes by our defence.
"I thought 3-0 flattered Bournemouth especially when we gave them two of the goals.
"There were other aspects which did not please me including a booking for Albert Jarrett for dissent and he will get what is coming to him now."
