I use to use it once in awhile for mites still works for me but i dont treat them as often anymore because its time consuming and within months due to being by an old barn with rodents they get infested again so now they can dust themselves or deal with it.
I didnt see ivermectin on the list so im good I dont buy the other stuff id sooner cull a bird that need that before paying allot for something that might not even work
