Should I add an insect growth regulator(IGR) to Bifen IT to keep roaches and other pests out of my home?
We always recommend using an IGR such as Nyguard or Gentrol to help break the roach infestation cycle. We also recommend using a roach bait gel such as Advion Roach Bait Gel to help get rid of those roaches that harbor in areas where you cannot spray (cabinets, drawers, counters, around sinks).
