I think anything with spinosad should work. I've heard people on Reddit will say spinosad doesn't work on spider mites, but it's gotten rid of them just fine everytime for me. (And Captain Jack's specifically lists spider mites as one of the pests it kills.)

This is the concentrate I bought off Amazon (though it looks like it is a few bucks more expensive than the premix, and it's only 16 oz., but basically a lifetime supply either way): https://smile.amazon.com/dp/B001VJBYMC

If you wanna start with a standard premixed bottle, that's on Amazon too, as well as in any of the big box stores. (If your stores are like mine, they have a few classic pest products like Raid, fly paper, etc. over by the plants, but the main pesticide section in the actual aisles is where you'd find Captain Jack's.)
