weird bug in with petco crickets

[xVashtaNeradax]

I went to feed N'kulu some crickets I bought for him yesterday and when I tapped them out a long wriggle "worm bug" fell out with them. It looks very similar to a "calci-worm" except it is longer, thinner, and black instead of white. I would post a picture but it is currently covered in herptivite and I dunno if it would be id-able. I'm gonna try and clean it off and take some pix after class...does any one have any idea what it might be? Can I feed it, or should I kill it?

It DEFINITELY came with the crickets from petco, it was NOT in the keeper before this...

A very common pest found in cricket farms is the black "Wooley worm" (or Black Larva Beetle). The Wooley Worms feed off the crickets.

Don't they feed off the cricket poop? I didn't realize they ate the crickets.
