Okay thank you very much!!!
I really think the permethrin will help. It should start killing, whatever pest is alive, instantly right?
Does ivermectin injectable really help deter/treat mites and lice?
I haven't used ivermectin. Crazy Maizies post below is accurate for what I have read many times so I would trust it.
Egg withdrawal time I don't recall how long but know you are not supposed to eat their eggs for a while.....I recall it being longer than 2 weeks though.
Ivermectin can be used to treat the chickens, but you have an egg withdrawal period. You still would re-treat in 7-10 days. I'm not sure about how to use the injectable version though. The permethrin mentioned above treats both hens and coop.
