I live in NE Texas and the flies were terrible last year...........til I discovered the XP 820 fly tags. The flies just disappeared! :banana: :banana: Using them again this year, will switch next year.
These tags have absolutely changed my life, I was constantly spraying and dealing with rubs, none of which worked. I put two tags on the back of each cow's ear, one per calf.
Oh, and if one or two cows don't come in, no problem, the other tags cover them, no flies on them either.
These tags are just amazing. Another good thing about them, not a single one of the first-time applications got infected, usually I have a few, but not with these for some reason.
