There was an article in Practical Poultry about three years ago. A new design of perch to limit red mite movement. It was a standard perch but was mounted using metal rods and inverted cups to stop red mite climbing up. Based on my experience it will have limited effect. Red mite will drop down from above and then be trapped on the perch, which we discovered when I creosoted the mounting ends of a perch and then put a roosting chicken as bait. No way was she carrying over 10,000 ! That's how many were on the perch in the morning looking for a way off. But fresh creosote only stops them for a week or so. Once it is dry they will cross it.
Suspending a perch rigidly on wires though sounds as though it will have the same effect permanently. All you have to do is spray the perches every morning to kill them off. Eventually there will be none left I suppose.
