How to get rid of mites in a Oryctes rhinoceros rearing containment?

I'm having hard time maintaining my Orctyes rhinoceros (Scarabidae) rearing project. The eggs of the O. rhinoceros kept hatching but later on they start to die off due to mite infestation. I read that the mites can be associated with fungus. But after I isolated the cadaver there was no sign of fungus on it after couple days. What can I do to successfully control the mite infestation. I'm maintaining the area by mopping the floor and I wash down the O.beetle adults with 10% bleach and brushed them with a tooth brush to get into small crevices. I also installed a shoe cleaning station at the entrance to help minimize contamination and soils, water and and all materials used were sterilized before use. I'm thinking about using a UV light sterilizer but I'm afraid it might also kill to O. rhinoceros larvae and eggs. The spiracles on the larva started to turn white. Looks like some kind of mold.

Mite proliferation.
There was a video, a computer simulation, of a mite swarming. Typically the mites stay near their hatching area which has a food source. If the population overwhelms the food source they start ranging around. The computer simulation was taken for a mite infested abandoned birds nest. Taking samples of where the mites expanded their area the simulation represented than as red dots in a 3D view. A mass of tens of thousands of dots spreading out like a carpet 12 to 15 feet across. During the day they find any dark place they can find then start foraging. It only rakes a few of the foraging mites to create another similar colony.
The mites in the study, Pyemotes, predatory, literally covered most of a small tree, feeding on the sap from the leaves and waiting for bird hosts to migrate onto. Fresh blood from a new host amped up the reproduction perpetuating the cycle while spreading the mites over a wider area.
First noticed and described in Kansas, Pyemotes herfsi, from Europe, has now spread to Nebraska, Oklahoma, Missouri, Tennessee, Texas, and Illinois.

No doubt many other predatory mites emulate this behavior. So cleaning out a terrarium probably won't work. Every little cranny and crevice within feet of the containment has to be cleaned with some substance that will kill the mites. Very wet water will drown them if exposed long enough. 1 to 3 hours. Alcohol in the water might accelerate the kill. Permethrin is the weapon of choice but extreme care must be taken to avoid other invertebrates from eating the substance.

Grain mites at least are attracted to moisture and explode in numbers rapidly

Do not use UV over live animals you want to keep healthy

Suggest placing sliced edible mushroom into the enclosure, they may attract to this.
After a while remove mushroom and repeat as needed.
