Hello, 

Unfortunately we don't have anyone who specializes in mite who would be able to identify this past order.   They are likely either the tropical rat mite, Ornithonyssus bacoti,  tropical fowl mite, Ornithonyssus bursa, and northern fowl mite, Ornithonyssus sylviarum, which are all common house invading species. 

Since you are finding them in your home I would recommend looking for a host animal such as mice or a bird nest around your home that could be the source of them.  Remove any dead mice or birds that you find. Remove and dispose of empty nests. Do not disturb nests if eggs or young birds of federally protected songbirds are present. If the nesting season is over and only adults remain, you may remove the nest without harming the birds. Pigeons, starlings and house sparrows are not federally protected. You may remove their nests any time. After removing the nest wash the walls with a strong spray of water to dislodge any mites. 

You can apply and an insecticide application around the outside of the home around windows and doors helps keep bird mites out of a home. Effective insecticides include: permethrin, ß-cyfluthrin, or deltamethrin, or you can hire a professional pest management service to treat your home.  If treating yourself always read and follow the label/directions. THE LABEL IS THE LAW. 

Physical removal is the best way to control when mites that are already found in homes.  I would focus on the rooms you are finding them in.   Declutter, cleaning and vacuum daily can reduce the population. Vacuuming however, will not kill the mites, so you either need to freeze or throw away the vacuum cleaner bag to prevent the mites from crawling back out.   Use a wet cloth to wipe them up.  Stick cards and tape may also be useful.  Since they like humid environments running your AC and/or dehumidifier may also help to dry them out.  

With regards to clothing and bedding I would treat them similar to bed bugs.  Wash everything in hot water and dry on high heat and keep them stored in plastic bin with tight lids in a room that you are not finding them in.  

Texas A&M Extension website "insect in the city" has a nice webpage about biting mites that was some more information about controlling them in the home: https://citybugs.tamu.edu/factsheets/biting-stinging/others/ent-3009/
