Ok, after doing some quick research, here is what I got:
1) Link to Petco's care sheets. NO WHERE in the BP care sheet does it say feed crickets. There are, however, some other inaccuracies in their sheets.

2) Their care sheet for Garter snakes DOES recommend feeding crickets, so possibly a little employee confusion...
