Already did the deep clean of my whole house and the room but definitely finishing this run and doing another cleaning. I kinda have alot going on rn so dumping is not an option. And start over from spores? Now you're just being dramatic. I’m still pulling decent yields in totes on the same shelf, look at my potd..
Luckily i have an interim space to move a few clean jars over to and expand.
I don’t think they were chewing through my filters as much as just crawling up the threads of the plastic one piece lids.
For your sake I hope you're right. I know for sure mine were chewing throigh filters as I kept seals on my jars to try to fight them.
Also, their eggs can definitely be in your agar and you'd never be able to tell. In my experience, starting from spores isn't dramatic at all. But again I hope for your sake that you're right and that you caught them early enough

From all my reading they seem like theyre relatively common in food, and on grain, if they were a bad pest I’d expect to see more literature about them, but everything I read makes it seem like management isnt that hard, they don’t fly so that means physical barriers are effective(ie tanglefoot on shelves) and if I keep the floor clean and bleached there wont be any habitat or food to encourage them to traverse, and all cracks have diatomaceus earth which will kill them.
I have dealt with mite infestations in cannabis before and theycarent the end of the world in that either.
To me it seems like they’re just as likely to be on a sporeprint as they are to chew through SFD’s
Would be interested in hearing more info about your infestation and what steps you took before throwing in the towel.

that agaricus.ru site is awesome, thanks for linking it! was reading mushroom flies article and thought of central heat/air and we need tp pick up some more new furnace filters (have been changing out the 90 day honeywell FPR 10's monthly since home reno project finished end of Oct). thought to mention that to you as well, in case you have similar central heating system and haven't changed filter since all this started.
i imagine easy enough for mites/eggs to get sucked into intake and be all up in filter until blown back into house might consider adding filter to intakes in house until they are eliminated, just be mindful of burning out old heater blowers if too much resistance for in and out.

Bumping this to say I haven't seen any issues since my thorough cleaning. I havent had anything fruiting in the room for about 2 weeks, all my new grain has been from agar in jars with silicone seals or plastic wrap and looks good. Gonna do another deep clean and start fruiting again. No more unexplained contams, although I did realize I’ve been prepping my millet way to dry so that was also happening alongside the mites.
I would also like to add that even the totes that clearly had mite trails fruited decently so who knows how common they are, could be sneaking around in alotta grows causing mysterious contams. If you’re using plastic lids, especially unmodded, theyre a leg

Fuck me I spoke too soon. Lost one jar a couple days ago and one bag. The jar was on on the same shelf my initial issues happened on, and the bag was g2g’d from a jar on the same shelf. Either I g2g’d them and mites were on the outside of the master jars and only 1/6 jars and 1/4 bags got mites from the g2 or they snuck in past a new ball leakproof seal or two. Still haven’t seen hem in anything from newer agar though. And even the tote they were obviously present in performed decently.. Still doing mostly successful sterile work and feel pretty good about the silicone seals, so far nothing has gone visibly wrong with any of those and still no signs of them in my agar.

Glue traps and sticky tape barriers are the only things I found that were effective in keeping them out of jars and cultures. If they try to cross over something sticky like that they get stuck.

Yeah, bug bombed and started everything over from cold storage cultures, used silicone seals and leakproof lids on my grain jars for a while and a liberal application of diatomaceous earth in all cracksa and crevices of the house.

AyePlus said: So far it has only happened with the white plastic one piece lids. Pretty sure they went past the filters and walked their way right up the thread. Could have definitely been brought in by gnats, and I also bought a bunch of the yellow sticky traps for them.
Strategies currently being enacted: -All afflicted jars have been dumped and rinsed, cleaned with hot bleach water before coming inside
I suggest using cool bleach water and washing with hot water afterward. Bleach loses it's effectiveness at higher temperatures. With everything else you are doing I doubt it matters much. Just figured I would let you know. Good luck! I never realized that mites were a problem with mushrooms. I think I'm gonna start working some mite prevention in to my cleaning techniques. Cheers.

I've run into the same issues you're seeing. I stupidly thought it was a good idea to grow mealworms in the same place I was growing mushroom cultures and the mites came in with them. They've gotten into everything, grain jars, culture dishes, etc!!
I'm not too sure what to do besides using 10% bleach on all surfaces, cleaning up the room as much as possible and vacuuming daily to remove dander, spreading diatomaceous earth everywhere, removing any source of food, setting bait traps on the floors with dried dog food, using a dehumidifier to drop the humidity in the room to below 50% (apparently they die off below this humidity) and doing all my work and growing confined solely to a high desk now that will be washed with bleach daily and have diatomaceous earth spread around the perimeter.
I hope it works, I've been blaming my sterile technique for a while as to why I was having a ton of failures, I never realised I had sentient little bastards working against me the entire time!

Been there. Feels.

Thymol as well as hops extract kill mites. There are beekeeping pesticide strips that are made of hops extract, hopguard I think it is called. Easy to hang around. A lot of terpenoids and terpenes kill mites. Many of them are also effective fungicides so be careful around live stuff. I haven't noticed thymol affect live cultures in the amounts I have used but cedar oil for example will fuck your cultures up.
They can't survive in liquids. They infest the space station too.
