Sevin spray and garden poultry dust

[the girls club]

I plan on using the Sevin spray on the walls and cielings of my coop. I have many nooks and crannies in my coop. Insulation is behind my wood walls and their are cracks that you can see the insulation between the wood. So I figure the mites have a good hiding place. The poultry dust will be used on my cement floor. Where the wood meets the floor. My nest are black plastic and it says to not apply the dust to the nest litter. So would it be safe to spray the sevin their.
I plan on washing my chickens or do or should I just use the poultry dust. Any advice would help me greatly as this is the first time I ever treated my chickens. They do need treated

The Garden and POULTRY DUST is a 2 pound shaker can. How much should I use on each chicken? Or another question would be .How many shaker cans should I buy to cover 5 chickens. I will retreat in 10 days
