About this product

This is the mix-it-yourself option for anyone treating both the inside of a home and its perimeter. Ortho Home Defense Concentrate dilutes with water for use in a tank sprayer, covering kitchens, bathrooms, garages, patios and foundation lines. It's built for recurring pest problems rather than a one-time spray, with protection against ants, roaches and spiders lasting up to 12 months indoors on nonporous surfaces.
