Does altoCIRRUS leave residual in cracks and crevices when used by itself?
altoCIRRUS Fogging Concentrate provides great flushing action, but no residual is left behind. You may want to consider Shockwave. This new fogging concentrate delivers the highest-level immediate control with the added benefit of an insect growth regulator (IGR). Shockwave will flush insects out of their hiding places, provide fast knockdown, and lasting residual activity.
