[COLOR=800000]I've never heard that. Why would that be?[/COLOR]
I've never had to treat for lice or mites but have 2 containers of 5% Sevin dust I bought at Lowe's when they were on sale to have on hand just in case I did.
I do use it to dust nooks and crannies when I completely clean out a coop.
Carbaryl, just like all the insecticides in that family, do not have the persistence of chlorinated pesticides. Although toxic to insects, carbaryl is detoxified and eliminated rapidly in vertebrates. It is neither concentrated in fat nor secreted in milk, so is favored for food crops, at least in the US. It is the active ingredient in Carylderm shampoo used to combat head lice until infestation is eliminated.
So of humans can use it for shampoo, why wouldn't one be able to dust their chickens and continue to eat eggs?
I weigh them at roughly those days, give or take. If they're on target at day 7, I'm not too concerned. If not, I weigh more often. The exact day doesn't really matter if using a graph so you can just plot the weight on whatever day you weigh to know if they're losing the correct moisture.
