Create an indoor bug barrier against common household insects with Ortho Home Defense Max Indoor Insect Barrier. This pest control product kills ants, cockroaches, spiders, fleas, ticks, scorpions, beetles, earwigs, silverfish, centipedes, millipedes, periodical cicadas, and other insects as listed (see product label for full list). The fast-drying formula has no fumes and leaves no stains, so you can use with confidence indoors. It spreads easily into cracks, crevices, under appliances, and into hard to reach places where insects hide - in kitchens, bathrooms, and basements, and around doors and windows. Easily apply with the ready-to-use spray bottle. Use Ortho Home Defense Max anytime you see evidence of insect activity or need to put down a preventative barrier to keep bugs out. Apply a 4-inch wide band to surfaces indoors where insects are a recurring problem or a 12-inch wide band around the exterior perimeter of your home. Spray Ortho Home Defense Max Indoor Insect Barrier until surfaces are slightly wet without soaking.
