Gentrol IGR? comes in 3 different formats: the aerosol can, the concentrate and the point source discs. The concentrate can be tank mixed and applied with your roach spray. The discs will last for 3 months, 1 disc covers 75 sq ft. and the aerosol form of Gentrol is convenient for treating flies around drains and sinks in homes, roaches in hollow table legs and voids in commercial kitchens etc. Gentrol should never be used to eliminate a roach population by itself (in any format). Gentrol will not kill roaches....it only prevents them from reproducing. You should use roach baits? and roach sprays? in conjunction with the Gentrol when treating for roaches.
