Rosehound,
I use Eprinox on my birds, once a year. I have for several years, and I haven\'t seen mites or lice anywhere since I started using it. A drop on the tail area does the trick....and, I haven\'t killed anyone yet...eat the eggs all the time. I also use Adam\'s when off to the shows. I think more for my own peace of mind then anything.
You should always exercise caution when using anything not labeled for poultry...as stated, it is a no no....but, try to make me not use neosporin or aspirin on my critters and see how far you get. I don\'t eat my birds, horses, cats, dogs, or guinea pig...so it\'s a no-brainer for me.
