I’ve had the worms in the bag of Purina food! I store my food in a plastic container with a lid and I was surprised to randomly find a moth fly out every so often when I opened it to feed my dog. It wasn’t until I got to the bottom of the bag that I finally noticed the small wriggly waxworms crawling about.
So the waxworms turn into Flour or Meal Moths and they generally find their way into food during packaging and storage. It can happen with an brand of food. Each female moth can lay up to 400 eggs. And when the conditions are right, your food is infested with worms. And they eat the food over the course of 2-3 months the chow down on the kibble until they cocoon for 2 weeks and emerge as moths. And the cycle continues.
It’s not a ‘dog food’ issue. Almost every grain silo worldwide has insect issues, including Meal moths. Most are treated with food grade Diatomaceous Earth or something equivalent. It’s not that the food is spoiled. It’s that some insect got dumped into the bag along with the kibble, settled down and decided to have a family.
It only take one female to ruin a bag of food. The worms are harmless, but I wouldn’t make my dog eat them.
Petco did refund me the bag of food.
