A very mild soapy water spray a couple of times per week should take care of your mites. About 1/2 tsp. to a liter size spray bottle - but maybe not on your orchids. They don't like the salts in the soap. Misting tropicals that are indoors in winter isn't a bad idea anyway. Help keep their humidity up. If the mites are on your orchids you may have to go get some Neem oil concentrate. You can use it on everything else, too, but it's a lot more expensive than soap.
Trader Joe's sometimes have some really great orchids, and they're always reasonable. Love that store!
