Indoor insect barrier. Creates a bug barrier against common listed household insects including ants, cockroaches, spiders, fleas, ticks, scorpions, beetles, earwigs, silverfish, centipedes, and millipedes. In addition, the pesticide specifically kills and prevents ants, roaches, and spiders indoors on non-porous surfaces for 365 days. Use anytime as a preventative treatment or after you see evidence of insect activity inside or outside the home. You can apply with confidence indoors (kitchens, bathrooms, doors & windows, basements), as it leaves no stains or fumes and dries up to 30% faster (vs. other Ortho formulas).
