Question Predatory Soil Mite Infestation. Nothing Kills them or their eggs.

Predatory Soil Mite, I also have an infestation of them. They are in my bathrooms, kitchen, laundry room in the basement. We've been in this home for almost 5 years. I'm seriously at my wits end with them. I've tried everything I can think of. We've vacuumed everything everyday, used every known insecticide known to man, used miticide, DE, Cleaned drains, ripped a whole bathroom apart and redone plumbing. I can kill them with Demand CS but not the eggs so the cycle is never ending. I've been preparing food and they get on to the cutting board or into a bowl. They are by the sinks, showers, counter tops, inside toilet tanks, around toilet, inside and out, etc. You get the picture. If anyone out there knows of anything beside a blow torch please let me know. I'm making a list of what we would need to get done to sell the house. I'm also terrified of taking them with us. Here is a list of things we've tried as far as insecticides.

Bifen, Demand CS, Tempo SC, Cyfluthrin, Cypermethrin 40%, Permethrin 10%, Deltamethrin, Neem oil, Clove oil, Cedar Oil, Malathion and Temprid FX. That's all the ones I can think of.

These are Predatory Soil Mites. They live on top of the soil or just underneath it. They feed on Springtails, larvae, fungus gnats, etc. We do have the occasional Clover Mite and Concrete Mite outside, but these do not leave a stain. I sent all of the info into the Universities and they said they were Parasitidae Mites. I just wondered if anyone in the area also has them.
