Ortho Lawn Weed Killers and Home Defense Insect Killers for Your Yard

Yes, when applied as directed. Ortho WeedClear kills over 200 listed broadleaf and grass weeds, including dandelion, clover, and crabgrass, down to the root, and Weed B Gon handles chickweed, clover, and oxalis. Both are formulated to get results with a single application rather than repeated treatments.

It depends on the weeds you have and your lawn type. WeedClear is broader-spectrum, covering over 200 weeds and safe on Bermudagrass, Buffalograss, Fescues, Kentucky Bluegrass, Ryegrass, and Zoysiagrass. Weed B Gon targets chickweed, clover, oxalis, creeping Charlie, ground ivy, and wild violet specifically. Check the label against the weeds in your yard before deciding.

The product details do not specify a mowing requirement, but weeds generally absorb herbicide better when they have enough leaf surface exposed. Follow the label directions on your specific bottle for timing, since application steps vary between WeedClear and Weed B Gon.

WeedClear is fast-acting and rainproof within 1 hour, with visible results from a single application. Weed B Gon is rainproof in 6 hours. Neither product lists an exact number of days to full results, so expect the weeds to die back to the root over the following days rather than instantly.

WeedClear becomes rainproof in 1 hour, and Weed B Gon is rainproof in 6 hours, meaning rain after that window shouldn't wash away the treatment. Try to apply when no rain is forecast during that initial period so the formula has time to absorb into the weeds.

The product details don't give a direct answer on wet grass application, so it's best to follow the specific label instructions on your bottle. Since these formulas work by absorption into the weed, applying to dry foliage is generally the safer approach when the label doesn't state otherwise.

Always dilute and apply according to the label directions; WeedClear concentrate is meant to be diluted for use with a tank sprayer or the Ortho Dial N Spray, and the ready-to-use versions are pre-measured. Using more than directed won't harm the lawn if you follow the coverage guidance, such as the 5,000 sq. ft. or 6,400 sq. ft. treatment areas listed.

Yes. It kills tough home-invading insects including ants, cockroaches, spiders, fleas, ticks, scorpions, earwigs, and silverfish, and creates a bug barrier offering up to 12 months of protection against ants, roaches, and spiders when applied indoors on non-porous surfaces.

The product is designed for use in kitchens, bathrooms, and around doors and windows, suggesting it's meant for occupied homes. The details don't specify a mask requirement or re-entry time, so check the label on your container for exact safety directions before and after application.

The 1.33 gal. ready-to-use container comes with a battery-powered Comfort Wand sprayer for continuous, easy spraying. Use it indoors around kitchens, bathrooms, doors, and windows, and outdoors along foundations, patios, decks, and garages, applying either as a preventative measure or after you notice insect activity.
