Hello - just started using Preen on our gardens (well established). Some of the bags of Preen (red) have tiny little beige specks. I understand that some Preen has corn gluten - could this be what it is? Might it be a pest? Whatever it is, it isn't moving. So, I'm hoping it's just specks of corn gluten and not dead pests (or at least, dead pests with no viable eggs).

Hoping someone has run across this -

Regards,

Slojo
