Kevin from United States writes,

Can I use an IGR with Permethrin SFR for longer fly control around cow farms?

I have used mostly Bifen I/T in the past around calf huts and other cattle areas. My residual control has only lasted about one week and am looking for another product to "change it up".


Yes, you can use Permethrin SFR with an IGR such as Nyguard IGR to control many types of flies in a barn.
