The Ortho Home Defense Max Indoor Insect Barrier Ready-To-Use battery-powered sprayer puts fast-acting pest control in your hands.

With a broad compatibility against common household invaders, this product helps you address evidence of activity or act as a proactive barrier. You’ll notice a practical balance between coverage and convenience in real-life use, whether you’re targeting a visible ant trail or preventing future intrusions in high-traffic areas.

What it Treats and Protects

• Kills and controls ants, cockroaches, spiders, fleas, ticks, scorpions, beetles, earwigs, silverfish, centipedes, millipedes, and periodical cicadas, among other listed insects.
• Long-lasting protection up to 365 days on nonporous indoor surfaces, helping create a more consistent barrier against indoor invaders.

Where and How to Use

• Indoor use: ideal for kitchens, bathrooms, basements, and around doors and windows. Outdoors, apply around foundations to build a perimeter barrier.
• Sprayer technique: hold the one-handed sprayer about 12 inches from the surface and apply in a 4-inch band for indoors (12-inch band outdoors). Spray until the surface is slightly wet, not soaked.

Why This Might Work for You

• Convenience: a ready-to-use, battery-powered sprayer that eliminates pumping or bending during application.
• Indoor usability: fast-drying formula with no fumes and no staining helps minimize disruption to daily routines.
• Flexible timing: use as a preventative barrier or in response to insect activity for ongoing home protection.

People and pets may enter treated areas once the spray has dried, according to label directions. Always follow the stated guidelines for safe and effective use, and reapply outdoor treatments every 3 months for best results.
