Come monsoon season in the NM desert, the fly populations tend to explode, but decreasing a suddenly-burgeoning fly population is controlled by using a multi-step method: 1.Thick layer of Sweet PDZ (“Stall Dry”) under roosting area, chickens will track a small amount to floor, into pine shavings.
2. Application of a fly bait prior/during ”explosion period”. PT Alpine sprayed on wall surfaces couple feet up from floor (and on vertical shady surfaces/crannies where flies might rest or hang out). Apply no more than every couple of weeks.
3. Fly sticky tape mounted horizontally in areas where flies may land/“roost”. They are drawn to their dead brethren stuck on the tape. Revenge makes good tape.
I wont use any form of the drowning traps, waaaay to stinky for us!!
