This bug spray for home kills common household insects including ants, cockroaches, spiders, fleas, ticks, scorpions, beetles, earwigs, silverfish, centipedes, millipedes, periodical cicadas and other insects as listed. This fast-drying ready-to-use refill formula has no fumes and leaves no stains, so you can use with confidence indoors. Plus, it dries up to 30% faster than other Ortho formulas. DIY homeowners can use this indoor bug spray whenever they see evidence of insect activity or anytime as a preventative barrier to keep bugs out. To use, attach the Extended Reach Comfort Wand from your previous bottle to the refill. Hold sprayer 12 inches from the surface and apply in a 4-inch band for indoor applications or a 12-inch band for outdoor perimeter applications, spraying until the surface is slightly wet but not soaking. People and pets may enter treated areas once sprays have dried. Trust Ortho with home protection to keep bugs out of your home during bug season.
