its disgusting! I just made a similar post about this. I went ahead and called the VP of the philadelphia herp society to get his advice. He suggested animal control and the PAACA (replaced aspca in philly) but I probably wouldnt have any luck. He has tried many times, but they do nothing. He thinks they are paid off.
I have come up with what I feel is a better solution. I have gone ahead and emailed some of the bigger suppliers of the pet stores foods and random other products. Maybe nothing will happen. Maybe the suppliers will ignore my emails. But if even one supplier of lizard food pulls their products from the store, because they dont want to be associated with such cruelty, I will feel like I accomplished something.
