About this product

Ortho Home Defense Insect Killer Granules treat the yard itself, not just the house — spreading across lawns, flower beds and the foundation line to intercept bugs outdoors. The granules start working within minutes and keep protecting for up to three months per application. A 10 lb. bag covers a decent stretch of yard, up to 10,000 square feet, and pairs well with a standard spreader.
