Echo and Update...
Every time I see this post come up I shudder! I'm so afraid I'm gonna jinx myself.
Over NINE months now since the one single treatment and still NO bugs!
Btw, I'm in WA. Been seeing several posts in various places about the "Super Mites". The description of them is exactly what I had. Can kill a bird in just a few days. Don't migrate off the bird. Don't always congregate around the vent only but on the tail, back of the neck, right above shanks, etc. Resistant to Permethrins and Pyrethrins.
The only thing I would add that I might not have before is that is imperative to treat ALL your birds at the same time. It's a pain to spend several hours treating a couple hundred birds at one time but it beat the heck out of spending 3 years trying to get rid of them.
God Bless,
