Sevin dust?

Not sure why you would need both... super bad infestation?

But yes, you can use both at the same time.

I would go with permethrin 10 concentrate that is mixed with water 37 ml per gallon. It is inexpensive—$7 a pint at TSC, and it makes many gallons for use in a spay bottle for treating chickens, or in a garden sprayer when treating a coop, roosts, and nests. Sevin or carbaryl is no longer approved for poultry and has been losing it’s effectiveness.

I was just told that Sevin Dust has a "Lifetime Egg Withdrawal." I've been using it in my coop & have sprinkled it on a couple of our hens -- so now their eggs aren't safe to eat? I was told to use it because others said their vets suggested it ??!! I am buying the Permetrin soon though, instead of using the Sevin Dust. I use DE in their outdoors dust bath area too.

I have used Sevin in the past, and ate the eggs, and I am still alive. If that worries you, wait a couple of weeks to use the eggs. Here are a couple of older studies, one where they used liquid Sevin (carbaryl) to dip chickens, and found a small up to 56 days:

Here is another which says it is very decreased after 7 days of treatment:
