The Ortho Home Defense Max Indoor Insect Barrier is a user-friendly insecticide designed for indoor use to kill and prevent a wide range of common household pests including ants, roaches, spiders, fleas, and ticks.

One notable feature is the Extended Reach Comfort Wand, which allows easier application in hard-to-reach spots without bending or hand fatigue.

Its quick drying time and lack of lingering odor improve the indoor experience compared to some other insecticides.
