Ortho Home Defense Insect Killer for Indoor & Perimeter is a ready-to-use pest control solution that creates a long-lasting bug barrier around your home. This Costco value pack includes two 1-gallon bottles, each equipped with a battery-powered Comfort Wand featuring one-touch continuous spray, so there is no pumping or repeated squeezing required. The active ingredients are Bifenthrin and Zeta-Cypermethrin, a proven insecticide combination trusted by homeowners for over 100 years.

A single application delivers up to 12 months of protection against ants, cockroaches, and spiders on non-porous indoor surfaces. For outdoor perimeter applications, reapply every 3 months. The formula dries clear and is non-staining and odor-free, making it safe to use in kitchens, bathrooms, basements, and around doors and windows, as well as along foundation perimeters, patios, decks, and garages. People and pets may re-enter treated areas once the spray has fully dried.

This product kills a broad spectrum of listed insects including ants, carpenter ants, cockroaches, spiders, fleas, ticks, scorpions, silverfish, earwigs, beetles, centipedes, millipedes, mosquitoes, stink bugs, wasps, hornets, and many more (see product label for complete list). It can be used indoors as a spot treatment along baseboards, cracks, crevices, and behind appliances, and outdoors as a 12-inch perimeter band along the foundation. Do not apply as a broadcast spray indoors, and do not use near electrical equipment, vegetables, or food crops. This product is extremely toxic to fish and aquatic invertebrates; prevent runoff into storm drains, ditches, or surface waters. Wear protective clothing including long sleeves, long pants, and chemical-resistant gloves when applying.
