Will Bifen IT kill flies?

We live next to a farm and our outside porch and siding gets infested twice a year with flies. We need an effective low/no odor and non-staining solution & hope this will be it!


Yes, Bifen It would be a great choice to treat flies. It dries clear and is odorless. You can apply the mixed solution to lawns, trees, shrubs, indoors. It has a long lasting residual. You may want to retreat during the fly season once every 30 days. Otherwise Bifen has a 3 month residual.
