The only products registered by the EPA for fly control on cattle are all Permethrin based or Pyrethrin based. This is because these product tend to give a fast kill yet also go away fairly rapidly.
The quick answer is no, there is nothing registered by the EPA for use on cattle that will last longer.
A better product than than Atroban is Vector Ban Plus. It contains Permethrin (10%) plus PBO (10%) which makes the Permethrin almost twice as potent.
Interestingly, Fipronyl (Termidor) is used for flea and tick control on dogs and cats. It is not labeled for use on cattle for flies. Do the research.
Imidachloprid is also used on dogs and cats for fleas and ticks. It is sold for termite and pest control as Premise. Maxforce Fly Spot Bait contains Imidachloprid, yet is only sold as a bait, can be mixed with water and sprayed, but is not labeled for animals. I think it would work great on cattle for fly control, but it not labeled for such use.
What amazes me is that these 2 products are sold around the world for flea and tick control, and in some countries as fly control. Permethrin on the other hand, is widely known to kill cats, birds and bees, yet is one of the only products registered for use on cattle for fly control. Go figure.
