Ortho Home Defense Insect Killer Refill2 – Indoor & Perimeter, 1 gal

Meet the Ortho Home Defense Insect Killer for Indoor & Perimeter Refill2, a ready-to-use spray designed to help manage common home-invading pests with a lightweight, fast-drying formula.

What pests it covers: This broad-spectrum solution targets a wide range of household intruders, including ants, beetles, centipedes, cockroaches, crickets, fleas, flies, millipedes, mosquitoes, moths, spiders, stink bugs, ticks, termites, periodical cicadas, and more as listed. When applied as directed on non-porous indoor surfaces, it can create an indoor barrier that lasts for up to 12 months. The Invisi-Shield Technology formula helps keep fumes low, dries clear, and dries quickly, making it suitable for use in spaces where families gather.

Where to use

Indoors, target kitchens and bathrooms or areas around doors and windows. Outdoors, treat the foundation perimeters, patios, decks, garages, and other areas where insects tend to congregate. For indoor surfaces, apply with a steady hand, holding the sprayer 12 inches from the surface and delivering a 4-inch wide band; outdoors, use a 12-inch wide band around the home perimeter. The area should be dampened, not soaked. After drying, people and pets can re-enter the treated space.

How to apply

• Indoor surfaces: hold the sprayer 12 inches away and apply a 4-inch band until slightly wet.
• Outdoor perimeter: spray along the foundation with a 12-inch wide band around entry points and problem areas.
• Re-entry: wait for the spray to dry before allowing people or pets back into the area.
• Refill compatibility: reuse your Comfort Wand from the original container for continued convenience.
