As for in Canada, I think you can get this. It's 0.35% permethrin. I realize it doesn't say on the label for mites and lice, but will work. Some people swear by DE but it work for me either.My chickens have mites or lice, I cannot tell but they are not looking well. I treated them with DE 4 weeks ago and they look worse. I am in Canada and have no access to any Electoral psp or permethrin. Help!
