Same here...when I put mine on in February, one of the hives really went to town on it fast, after I replaced it the second time, real pollen was coming in and I noticed the patty pieces were being chunked out the front door. I think they have their uses though. Im going to give a package that Im getting in April one to see how they take to it (or not). My feeling is that once they have active foragers, that they will ignore it though.
