Product Q&A

Answer:

Allow Gentrol Aerosol IGR to sit in the drain overnight before using.  For drains, apply product into and around the downspout and catch basin area. Coat these areas thoroughly as fly larva develop in the scum buildup on the sides of drain pipes. Repeat applications at 2 to 4 week intervals depending upon the severity of infestation
