Wonders if the blow torch method is how 'burn the whole coop when you have mites' method(Oh, I meant to do that) actually started?
But I've never had roost mites(knock wood).
Would saturate all cracks and crevices with permethrin spray if I did.
I never use any liquids to clean coop, tho I do use water to clean outside of a few windows that are tipped open to the outside all summer once I close them in fall.
This is how I 'clean':
-I use poop boards under roosts with thin(<1/2") layer of sand/PDZ mix, sifted daily(takes 5-10mins) into bucket going to friends compost.
-Scrape big or wet poops off roost and ramps as needed.
-Pine shavings on coop floor, add some occasionally, totally changed out twice a year, old shavings added to run.
-Runs have semi-deep litter, never clean anything out, just add smaller dry materials as needed.
-Nests are bedded with straw, add some occasionally, change out if needed(broken egg).
There is no odor, unless a fresh cecal has been dropped and when I open the bucket to add more poop.
That's how I 'clean', have not found any reason to clean 'deeper' in 5 years.
