I'm not @Dagmarvelous but are you sure you have mites? I thought I did but it turned out to be a laundry soap I bought. I washed my bed and sprayed the mattress thinking I had something that was biting me as had a lot of what looked like mosquito bites all over. I went out and bought some free and clear laundry soap and no more issues. I not suggesting that that is you problem. It also happened to a friend of mine. He even bought a new mattress and threw the other one out and then changed his laundry soap. Good luck...
