The best results I've had with scaly leg mite is with Scarlet Oil...it's actually an equine product, in an dark blue aerosol can. Very easy to apply and if you're treating more than one bird, the fact that it's tinted pink helps keep track of who you've medicated and who still needs treatment. We spray every day for a week then no treatment for a week to 10 days, then retreat for another 7 days. Works like a charm!
