I know I’ve probably asked this question before but how safe is Permethrin around my chickens? I have a lice infestation, my birds are losing feathers like crazy and some are bald around the neck and on their back (I have no rooster with them). I’ve seen the lice on me when I’m doing things in the pen and they do bite! I have permethrin concentrate and the 0.25% dust. What is the proper way to use them? I have permethrin 10 concentrate and I heard it was 5 ml per quart of water wanted to double check if it’s correct. Should I spray it directly on my birds and spray my whole pen with it? And for the dust I have the same question, do I put the dust directly on the birds and in the bottom of the pen? What about chicks around 2 months old is it safe for them also? I don’t have anywhere to move them when I’m treating the pens so that’s another concern I have, can I treat the pens with them still in there? Their pens are well ventilated and mostly open.
