When all (or nearly all) the flies are inside the jar, I just put it under the tap and run water over it until it fills up through the holes. Then leave it for a few minutes to drown them all, and dump it down the sink.
You can just use some apple cider vinegar with a drop of detergent and skip the labor part (just take the plastic off and dump the mess down the drain). Refill & rekill.
