Harris 5 Minute? bed bug foaming aerosol uses patent pending technology to kill bed bugs in just 5 mins after initial contact. In addition to the quick kill, the spray features a residual that lasts 1 month. A few additional benefits include EPA acceptance for application on all parts of the mattress, not just tufts and folds. Harris 5 Minute? bed bug killer is odorless, non-staining and kills pyrethroid-resistant bed bugs and their eggs. With a quick time to kill, 1 month residual kill and EPA accepted application on the entire mattress, this formula makes a great addition to the Harris bed bug product line.
