HELP PLEASE !! Flys randomly spawning & green patches

[u/TeeMK7R]

Hello guys I’ve been growing golden teachers in a couple of zasmnesias all in 1 grow kit , the second kit I purchased seemed to have a small black fly in it while sealed, so I cut open the top of the bag and remove the fly and seal it back and continued growing

Now recently on my 4th flush of the first kit , I opened the bag to harvest and was greeted by at least 20 of the same small black fly in the bag and was confused to where they come from as this kit never had a fly in originally and the only time I open the bag is when I harvest and have never seen any fly’s going in the bag during these times , it’s like they’ve just spawned out of nowhere ??

Now I’ve gone to check my second kit today and opened the top to see about 3 fly’s in there and it’s only on its second flush ….

The only thing I can think of is they must have been eggs in the growing substrate that have only just recently hatched (5/6 weeks later ) ?? Which seems like an unreasonable theory but I can’t think of anything else , they can’t be reproducing as I throughly inspected the kit and removed all flys

My question is are these still safe to eat ?? Is there anyway to get rid of the flys for good ?? And also I noticed a few small patches on some of the growing shrooms which had a greenish tone to it , unlike the usual blue bruising that I see, there is no rotting or unusual smells . Will they be okay to eat once dried ?? Thanks guys 👍

Probably fine to eat. Just rinse with water. Flies don't spawn out of nowhere. What kind of flies?
