I will try that recipe and see what it'll do.
If they don't fly, it's most likely springtail. they can be white or black. fast moving small little bugs.
I had so many of them on old bark media on one of the phalaenopsis last year. They were found on the bottom of the pot, but lots and lots of them would climb on th edge of the pot when I watered the plant. Once I repotted the plant into fresh media, I saw much less of them although they persisted. I think some of them hitchhiked on the root or something.
They don't do harm, but they look gross!
Let's get rid of those little suckers!
