The Ortho Home Defense Insect Killer is a large 1.33-gallon spray designed for both indoor and outdoor use, especially around home entry points like doors, windows, patios, and foundations. Its active ingredient is bifenthrin at 0.05%, a common and effective chemical for killing ants, cockroaches, spiders, and many other pests. It offers long-lasting protection for up to 12 months on indoor non-porous surfaces, helping prevent repeat infestations without frequent reapplication.

The Comfort Wand applicator is battery-powered, making spraying easier and more continuous, which can save time compared to manual pumps. The spray creates a barrier that kills a variety of insects, providing versatility for homeowners dealing with multiple pest types. Products with bifenthrin generally have a mild chemical smell that dissipates after application, so ventilating treated areas is advisable.

As with any insecticide, care should be taken to avoid direct contact with skin or inhalation, and the product should be kept away from children and pets. The residual effect is most effective on hard, non-porous surfaces. This product is suitable for homeowners seeking a broad-spectrum, long-lasting pest spray with ready-to-use convenience and easy application.

One of its biggest advantages is its long residual protection—up to 365 days on nonporous indoor surfaces—helping keep your home pest-free for a full year after application.

The spray comes with an extended reach comfort wand, making it easier to apply without bending, which is handy for spraying around baseboards, under furniture, or in hard-to-reach corners. It can be safely used in kitchens, bathrooms, basements, and around doors and windows, and even outdoors around your home's foundation. Some users may notice a chemical odor during and shortly after use, which could be unpleasant if you’re sensitive to smells. As with all chemical insecticides, it should be applied carefully according to instructions to ensure safety around children and pets.

This spray is well suited for homeowners looking for a strong, all-in-one indoor ant and insect solution with long-lasting effects, especially if you want something easy to apply across multiple problem areas.
