Ortho Home Defense Max Indoor Insect Barrier Refill offers a ready-to-use solution to help you create a protective bug barrier inside your home. This 1 gallon refill is designed to attach to your existing Comfort Wand, enabling quick prep with minimal fuss and no fumes. The formula dries fast and leaves no noticeable stains, so you can proceed with confidence as you address insect activity or set up a preventive barrier.

What makes this refill stand out

• Fast-drying, stain-free formulation that minimizes interruption to daily living
• Kills and prevents a wide range of common household invaders, including ants, roaches, spiders, fleas, and ticks
• Indoor protection can last up to 365 days on nonporous surfaces, helping you maintain a long-lasting barrier

Designed for DIY homeowners

To use, attach the Extended Reach Comfort Wand from your current bottle to the refill. For indoor applications, hold the sprayer about 12 inches from the surface and apply a thin band until the area is just damp. For outdoors, widen the band to about 12 inches around foundations to help deter intruders from entering. After application, allow the treated areas to dry before people or pets re-enter.

• Indoor use: maintain a comfortable distance to ensure an even, light coating around entryways, kitchens, bathrooms, and basements
• Outdoor perimeter: target foundations and adjacent ground to form a defensive barrier against intrusions

This refill supports a practical home protection routine, with the option to respond quickly to new activity or to establish ongoing prevention during bug season. Outcomes can vary by environment and the insects present, but the refill is designed to offer a convenient, ready-to-use solution for many households.

Usage scenarios and coverage ideas

Use indoors in kitchens, bathrooms, basements, and around doors and windows; outdoors, apply around foundations to create a perimeter. The spray is intended as a preventive barrier or as a response to visible insect activity, providing DIY homeowners with a flexible option to maintain a bug-aware home environment.
