Shockwave 1 Flushing, Killing & Residual Aerosol contains two adulticides and an insect growth regulator (IGR) to flush cockroaches out of hiding, kill and leave a residual for long-term control. It also contains two synergists that enhances the effectiveness of the other active ingredients and helps combat resistance. This all-in-one aerosol saves you time and money. With multiple modes of action, it eliminates the need for reapplication, simplifies training, and reduces waste. It can be applied in food-handling areas, and even sprays upside down so you can apply in tough-to-reach locations.
