Can Alpine WSG be used alongside Bifen LP Granules? If I spray the perimeter of my home with Alpine WSG and Nyguard IGR, can or should I use Bifen LP granular in the mulch beds and grass just outside of that perimeter? We are dealing with smoky brown roach nymphs, black ants, and stink bugs among other general pests.


Yes, Bifen LP Granules can be applied in the mulch beds and grass outside the perimeter of the foundation where the application of Alpine WSG and NyGuard IGR stops. These would not interfere with each other as long as the areas are not cross treated.
