mites in coop ?

there are hundreds of 1mm white/light brown mites in the coop, anyone know how to get rid of them?
for the last three weeks ive been spraying the coop with poultry/animal safe disinfectant but the mites are still there!

They need more than disinfectant.  They need proper mite killer.  There are several brands you can buy in the shops or online.  Good luck.

I use poultry shield purely because that is what I was able to get locally.  It cleared it up for me.  I also use johnsons mite spray afterwards as this offers long term protection.

I had an attack of the dreaded red mites, spent about 2 weeks going in on a night and crushing, then leaving clothes to go in washer and showering and they make my skin crawl, after using various treatments this did subside but the treatments I went on with for another 3 weeks which were a combination of hot water and soapy bubbles sprayed around all the areas of the hen house including the ceiling and because the weather was hot it dried quickly (the soap in my mind was they have a waxy scaly back and that is what you need to break down to kill them, so no idea whether it helped kill them or just in my mind..) and then doused with red mite sprays and bought some grey dusting powder online, which for the life of me I cannot recall what it was called, something like diatrom I think and spread that on the floor and into the corners and just kept repeating, maybe for about 5-6 weeks in total - its either put the effort in or buy a new coop

Dismantled our coup a few weeks ago and gave it a good soak and clean. I use a product by Nettex from our bedding supplier, they don't do poultry shield but it still does the job , forget how much it cost.     Have tried disinfectant in the past didn't work.   Pesky little critters , aren't  they!!
