mites of some sort-can anyone identify?

[gwchickenbutt]

Hi,
Today I noticed that these small piles of what look like very fine saw dust were actually moving.. ewww. See video:


Can anyone identify? I think it may be grain mites but I'd love a definitive ID. The mites are very small and tanish. They were near the bag of pellet layer feed. I've gone crazy with D.E. in the room where we keep the feed-and also gave the area a good cleaning to try to get rid of them. Any other suggestions?
Thanks!

If they are in your feed, you should toss it, and spray for bugs. I don't really know what it is, but see if they're in the bag.
