I had a problem a year ago with Wellness Lamb and Barley. The second bag I purchased (on the second day of use) had some winged thing crawling up the inside of the bag. I returned it for a refund and got on online that day to find that folks had been finding (over a 4 month period at that time) various infestations. In some cases not till they got to the middle of the bag - maggots. I believe the infamous Diamond Foods had gotten into Wellness production.
