what should i use for a chemical to kill mites in coop

[blueseal]

noticed lastnight that i have redmites in cracks and crevices and on chickens and nest boxes. i treated the coop and chickens with manna poultry protector spray. all i had was a 16 oz bottle. used that up and still have more mites crawling.

Clean out the litter, treat everything including the birds with Sevin 5% garden dust, repeat in 10 days. You may have to wet it and spray or paint it into cracks and crevices, or also purchase some in liquid form. Red mites are particularly difficult to get rid of, or so I have read.
