Mites threatening roach colony

Hi I thought I would solicit some opinions and help regarding keeping mites from harming my roach colonies.

My B bolivensis colony was recently overrun and nearly destroyed by mites. I'm pretty sure it started with a dead roach that I neglected to remove. I kept the roaches on a moist substrate (part of an experiment with worms), at normal room temperatures. One day I noticed a dead roach and it had mites on it. I buried it hoping the worms would eat it. Later I saw a lot of mites on the oatmeal in their food dish. Some time later I checked back and there were mites literally everywhere in there. All the oatmeal had been powdered and there were mites on every surface, including all over all the roaches. The roaches were trying to scrape the mites off and many of them were moving very slowly, laying on the ground etc. Anyway I freaked and moved all the roaches to a new enclosure that was bone dry. There was a water dish but that was it. Most of the roaches died some time later with just a few survivors. I haven't noticed any mites in the new enclosure but it was a very traumatizing experience.

Strangely my lateralis colony right next to it was unaffected by mites, although it was in the same conditions. However, it had a red lamp on it for warmth which I'm sure dried things out somewhat.

I was just doing maintenance on my laterals and I noticed some mites beginning to congregate in various parts of the enclosure, especially in the food dish. I haven't noticed any on the roaches, but I'm scared. My lateralis colony is important to me from a feeding perspective. I really don't want mites to kill them off.

I don't know what all the types of mites are, and which are dangerous to roaches. It's really hard to distinguish them because they are so tiny. I'm pretty sure they are off-white and very, very small.

Anyway, how does one control mites? The most obvious answer is to keep the enclosure dry, but when I did that I got no reproduction from the lateralis. On this moist substrate they are reproducing like mad, whereas when I had them on no substrate and when I had them on dry substrate I had no reproduction whatsoever.

Can you enlighten me on the different types of mites and how, if at all, they can be controlled? Are there any insects I could add to the colony that might eat the mites or something?

yes, go buy some H. miles. their apredatory mite that will eat all of the other mites then die off.

So if they die off, then you need to buy more predatory mites the next time mites appear? Can you keep like a colony of predatory mites or something? Or will the predatory mites stick around in small amounts and establish a little ecosystem with the bad mites?

It seems to me that whenever predatory mites have been mentioned there was an issue of where to get them. I'll have to look around and see where they come from.

Any other suggestions that might be helpful for controlling these nasty little guys?

you can get 10,000 here or 22.00 usd plus shipping. www.evergreengrowers.com also im not to sure about colonizing them but i know that H. miles will eat grain mite and other as well. if you have substrate with your roach colony they will lay eggs and hatch babies in about 2 weeks.

What happens to the predatory mites after the job is done?
I been thinking about getting some as I think one of my slings has mites(still not 100%), and it would be nice to get a handle on it before it gets outta control . . .

Edit- searched my own answer- They eat each other then die!

Now, i'm having the same problem actually and was looking into predatory mites such as H. Miles. I was pretty sure that predatory mites were very specific on which mites they would eat. I asked my professor, he said the same thing. Is there a common species of parasitic mite that H. Miles is good for? Im wondering if I could have a different species of mite and H. miles won't work. I'm going to collect some mites though and take them to a lab to put them under a camera microscope. I'll try to post soon.

Has anybody had luck with H. Miles from personal experience?

well as far as i know they will eat almost any common mite that would infest either a roach colony or t room.
