Spider mites!? Help

[YokaYampi]

Hello,
I have a collection of about 20 orchids and recently noticed a tiny spidery red thing or 3 crawling around an orchid. (Bht only one so far ) I’m planning to do a big repotting this year anyways and I thought it be a good time to treat the orchids for pests… I’m hearing a lot about neem oil, soapy water .. I’m just wondering what kind of insecticide would be safe to use on my phals, oncidium, bulbophyllum, psychosis, and vanilla plantafolia? Im not a huge fan of neem oil treatment so alternatives would be really helpful
Also
( they’re all in a tent, I heard raising humidity helps die off spider mites I’m hoping this holds them off until I can do the repotting in a few days, But how high? )
