Obligatory: well that escalated quickly. The beauty of the internet is, even on your bad days/weeks, you can proofread and stop what you've written. I've had a nightmare week that has physically made me ill (can barely eat) and may change my life and plans. Next time chill out and proof.

I know you've seemed to have resolved your issue, I just want to chime in because I've had a mite nightmare a few years ago. You definitely wouldn't just notice one mite. Definitely check under the chin (gently spread the scales) and around the eyes just to make 100% sure. You should be able to see mites there - and it should be easy since your banana is light in colour. There wouldn't just be one - especially as time has gone by.
