For German cockroaches
The most common and effective IGR used for German Roach control is Gentrol IGR, which comes in an aerosol, concentrated liquid, and point-source tablet. You would not use both the aerosol and the point source in the same location, however you would be using the IGR in addition to a residual spray and./or gel baits. Please read our German Roach Guide, for further information.
