I have a problem with mites on my Heterometrus petersii

Do you have a chance of posting a picture of these mites and scorpion?

Parasitic mites do not move at all. And they are hardly seen by naked eye.

For reference:

More on the subject will follow soon. We are currently preparing some informative stuff to be published at the forum regarding "good" vs. "bad" mites.

I'm grateful for your advices..  
Unfortunately I do not have proper camera so I can't take pictures, as I can see, picture of mites correspond to mites on my H. petersii, but I can see moving mites as well..Again I'll put coco peat in the oven, I hope that it will reduce the number of mites..

Mites are everywhere.  Most likely these mites came in on the food.  Unclean enclosures (uneaten dead food for the most part) encourages mite reproduction.  Sounds like you have a very clean substrate now so they should not continue to reproduce as fast. 

I have read that some keepers have had success with predatory mites.  They are supposed to devour the parasitic mites and are harmless to pet arachnids.  Once the parasitic mites disappear, simply drying out the enclosure removes the predators as they die quickly from the lack of water.   May be easier than a complete enclosure microwave nuking?  Downside is that they are pricey.

You can find them out on Amazon and some other organic gardening sites.  Good luck either way!

Not everything that is small and white are mites actually.
Forest setups very often get "creatures" that we mistakenly think that are mites. Some call them springtails but I'm not 100% sure if this is the correct "ID". These usually are tiny and what, like mites and more quite fast on the substrate and over the scorpion. They are also harmless.

Predatory mites often appear by themselves to eat any left over feeder parts. They also move but are slightly bigger in size.

Back to the bad/parasitic mites... the best way to ID them is that they do not move at all. They are like tiny ticks that attach to the "weaker" parts of the scorpion, between tergites and junction of the legs and tail (as seen in the picture). In my experience, they can often be seen in the prosoma as well, in the area between the eyes.

I noticed that when the peat is drained, their number is reduced, but I'm worried about scorpion, I don't want to hurt her because of dehydration...She has a constant fresh water supply in the container which is filled to the top, but I'm still worried.
I would not take the chance with other predatory mites, sometimes it is not wise to play with nature..Again I'll put peat in the oven at a high temperature..

For cases of parasite mites, I agree it might not be wise "to play with nature".

Dehydration is a more critical issue that we must take note of as compared to mites infestation. (As in, mites being the lesser of two evils).

Water bowl is essential, so is an adequately dampened substrate. I would prepare a new enclosure with fresh bedding of substrate and transfer(for experienced keepers) the scorpion over upon a successful molt. With great care and attentiveness during the transit. My 2cents.

Keep us updated on how it goes. Gd luck.

All my animals (102 speciments, 27 species) have adequate dish with water, every second day I take out dish and wash it under running water to remain clean...As soon she moult I'll remove the exoskeleton, I hope that I will remove all mites...

Hello,

Any updates?  Curious to see how your battle is going.

I think I've managed to reduce the number of mites on H. petersii, and i think she will moult, soon..   She is very slow and her tergits are duplicated.....  Some of my tarantulas have molted, I got bit and etc..

Ouch!  Hopefully the bite was from a mite!   .  I still think the predatory mites would be a great test.  But, if you have the tenacity to keep attacking the enclosure, I am sure you will win the war.  What a pain!

I think I've menaged to reduce number of the mites, about 70%..   
It was not to bad bite, just a little pain that's all..
