Grain mite hypopus nymphs? Oh, great!

Hey, folks. Guess what's new?

After our initial excitement from finding a local lizard and reptile store that sells feeder insects, today we found out that the store has grain mites.
The bane of my existence.

It isn't the worst infestation I've ever seen. That was our own bread drawer.
However, it happens that it is enough for them to hitchhike on everything we purchased there. There are even grain mites on the food dish, which is new and unused.

Stupid mites. Or are they anticipating the use of the dish in advance? How smart are they? :anxious:
Anyway, so now we have more stupid mites after getting rid of the first infestation.

After doing some research, I recently found out about an interesting aspect of their metamorphosis. The hypopus.
If I didn't dislike grain mites so much, this would fascinate me. This is a form of phoresis, in which the mites do not feed at all.
Instead, they attach themselves to animals such as insects and rodents and disperse, like some kind of seed.
I've known about grain mite phoresy for almost as long as I've known about the mites themselves, but I didn't realize that there was a specific stage of metamorphosis for this.

Unfortunately, we got crickets, dubia roaches, and superworms from there, and I suspect that some hypopi (apparently the plural) are probably on our feeders.

Anyway, from what I've heard, this "seed" stage, which is actually a nymph, is incredibly difficult to eliminate.
I'm sure that they would die inside of our lizard's digestive tract. But I was actually hoping to raise these feeders instead of feeding them off.
I previously posted a thread about breeding feeders.

Would there be any way to combat these hypopi?
Apparently, they are insanely tough and resilient due to their hardened carapaces, and are not sensitive to drying out as the adults are. I'd also imagine that they attach pretty firmly onto their hosts. So rinsing the feeders in water is not an option?

Anyway, I've heard of these "hypopi" being discussed on this forum, and I was wondering if anyone has any tips on setting them up to fail.
They cannot reproduce, since they are nymphs. Maybe they will die off without finding any food or moisture?
How long can these hypopi cling to their hosts and go without food, anyways? Is this a state of dormancy?

Any input would be appreciated. I have not even heard of these "hypopi" until now.
Thanks! God bless!

A purge and reset would be the path of least resistance. Not sure how much free time you got on your hands to combat them but I imagine it would be an arduous and time intensive endeavor, plus there's no gurantee you get them all...

Burn it to the ground I say. Scorch the earth.

You can play around with them if you wish. The longer you wait to get rid of all of them--the higher the potential they spread into your animal's enclosures.

Two rules. Hermetically sealed food source containers or keep in the fridge and they stop breeding below 50 F.
Here in Thailand. nothing quite like the huge straw, chaff and trash sifter blower on every rice harvester to assure 100% grain mite distribution across the entire country.
Every household in the country has at least a couple dozen seal-able plastic containers on hand. Since I hate single use plastic I pack rat a couple hundred before the boss gets pissed off and unloads them all on the nearest recycling center. Wash, rinse repeat.

Well, grain mites aren't usually dangerous to reptiles, so we can still feed them off. Unlike tarantulas which only feed on the innards, reptiles eat insects whole, so they'll eat the hypopi and all. And bearded dragons, which is what our predator is, don't get grain mites as bad since their enclosures are dry and barren rather than rich in organic matter.

I feel sorry for those who deal with grain mites in humid, moist habitats, especially bioactive, since they would probably wipe out their springtails with the mites while combating the nearly microscopic monsters. They really aren't so bad in the enclosures, since they only feed on decaying food and fungi. But they spread, and do they ever...

If they were bigger, I would cultivate them as feeders. If they didn't climb glass and plastic, I'd cultivate them as cleaners...

That got me wondering. Would slings and early instar go after them? Especially salticids. The mites are quite active which gives salticids a leg up on spotting them and we have all seen adults jump gnats barely larger than mites.
