Yes- that is the 5% dust.
Just be aware that since 2009 it is no longer labeled for poultry anymore, and so is not approved for chickens. We are supposed to be using Permethrin Dust now, or other approved chemicals.
Sevin works great and some mites are resistant to permethrin but it is not approved. There is an egg withdrawal period for sevin dust as well but not for permethrin as far as I know (toss eggs).
Don't ever put any insecticide in the nest boxes. DO change out the bedding and nest box material with every dusting though, and dust the coop well or spray it with liquid permethrin dilution.
If you put insecticide in the dust bathing areas, be aware that this stuff kills honeybees.
I hope this helps!
