Does the hive have a foul odor. That is usually the first sign. Our inspector swears he can walk through an apiary and pick out a possible American foul brood hive just by smell. Sometimes the smell is just dead bees so you cannot go by smell alone.
Since the wax is new, get some empty frames, put 3 rubber bands on each end, cut the comb, place it in the frame and slide the rubber bands over the comb to hold it in place. The bees will attach it to the frame in a day or 2 and cut the rubber bands off and drag them out the front door. This is the same thing you do when you do a cut out from a home or building. Look under Honey Bee Removal and watch the videos of how it is done.
Good luck.
