The thread has been tagged already by TV.

I had these mites in grain spawn one time. I looked around in my room and there were mites all over a bail of straw I had stored in leaf bag. Man, they were everywhere! I wiped every single thing down in that room with bleach water and bombed it. If i'm not mistaken, I still had problems even after that. I can't remember.

They kind of look like aphids.

I was really surprised they had gotten' into my grain jars. I almost croaked when I saw them all over the black leaf bag.

Since you all liked the picks so much I found two more that came out alright. I'm using an 8 mega pixel set on macro from about a cm or so away, so you can get an idea of how small these critters are.

It's really interesting that you mention the straw in a garbage bag. That's how I'd been keeping my straw bale outside (standing upright to repel rain covered in a black plastic bag). Didn't think to check for massive fungus mite infestations before use! :eek: The batch with the bad infection was from straw treated with steam (wallpaper steamer method) and I'm almost certain it did not get pasteurized well enough. A second batch from the same straw (more thorough steaming) is fruiting pretty nicely. The batches co-mingled in the same FC for a bit so I'm keeping my eye (and magnifying glass handy)...

Enjoy the pics!

Not sure since they blend in colorwise. I did notice them crawling all over on and in the coir casing in the first tray I threw out, if thats any help. Just looked them up in TMC... Per Stamets "Mites are known to eat mushrooms and their mycelia. Additionally they devalue the crop and crawl onto pickers, causing temporary discomfort. Their presence is an indication of unsatisfactory substrate preparation and insufficient pasteurization times and/or temperatures."

I cleaned out my FC as a precaution, but I think they came in with the under-pasteurized straw I was using rather than migrating in by some other means.
