I was at Wal-Mart the other day and seen Ortho had a new 'eco' friendly insecticidal soap, it was $5 so I thought what the heck. It worked on the aphids on my Calla Lily, something the homemade concoction was having trouble doing. I have not tried it on my chids yet, no problems with them...yet. But it did no harm to the Calla Lily and he is a sensitive little feller. (and more needy than my chids!) I also found Wal-Mart has SuperThrive for $7 a bottle (grabbed one of those too!) Good luck with getting rid of those mites. Eek.
