I'm building my coop out of old fence. So, I think I will have a higher mite infestation risk. I've heard a new way to kill bedbugs is heat. 120-130 degrees for 3 hrs will kill all adults, nymphs and eggs. I also heard taking a hair dyer and blowing it in cracks will make them come out. So, I'm thinking this may work in the coop also. During the spring clean-out, I will likely take a blow dryer to the walls and floor to make sure nothing comes out. I also think covering the coop with a tarp and putting a space heater in for 3 hours and getting the temp up to 120-130 degrees for a couple hours would be good for the sanitation of the coop (As long as I don't catch it on fire!). Has anyone done this or have any thoughts on the subject?
