I have also found microworms in my grindal worm cultures.  Don't worry about it
- the grindal worm culture just needs to be kept warmer.  When my cultures are
kept in the upper 70's - mid 80's, the grindal worm population is booming, but
when the cultures cool down to the lower 70's, the microworms (which compete
with the grindal worms for food) are able to out-reporoduce the grindal worms.
I have had the temps warm back up into the 80's for a few days, and the grindal
worms were once again dominant in the culture.

Actually, I was thinking that this might be a better way of culturing
microworms, as I can control the amount of food in the culture and avoid the
problem of the odor of old microworm cultures.
