Best Spray To Kill Dandelions for Lawns and Spot Treatment

#1 · Best Overall

1. Ortho WeedClear Weed Killer

• Weight: 9.4 lb
• Form: Spray

Best for: Precise lawn spot-treatment users.

Why it ranks #1: Its lawn-friendly formula targets over 250 listed weeds, including dandelions, and the one-gallon bottle includes a continuous-spray Comfort Wand for precise application.

The continuous-spray Comfort Wand applies Ortho WeedClear without pumping, enabling controlled targeting of listed weeds across the lawn. Its lawn-friendly formula contains three ingredients aimed at common weeds, including dandelions, while the label’s directions define the conditions for protecting grass during treatment.

The Comfort Wand’s continuous spray and precise control make it easier to direct application where weeds are growing without stopping to pump. The formula is listed for more than 250 common broadleaf weeds, including dandelions, clover, poison ivy, chickweed, and dollarweed, giving lawn owners a broad target list. It is intended for lawns and will not harm grass when used as directed. Allow the spray to dry before people or pets enter the treated area.

Skip it if you need to treat patios or gravel; Roundup Weed & Grass Killer4 lists those areas for use.

A practical fit for lawn owners who want wand-directed spot treatment of dandelions and other listed broadleaf weeds. Follow the label for grass safety, avoid application before expected rain, and wait for the spray to dry before people or pets return.

#2 · Fast Visible Results

2. Spectracide Weed Stop For Lawns

• Weight: 2.4 lb
• Form: Liquid

Best for: Fast visible lawn weed control.

Why it ranks #2: This lawn-use spray lists 460+ weeds, including dandelions, and claims visible results in three hours; it is intended for several named lawn grasses.

Visible results in three hours give Spectracide Weed Stop a clear timing advantage for lawn owners who want an early indication that treatment is working. Its ready-to-spray concentrate targets listed weeds, including dandelions, and is labeled for several common lawn grass types.

The contact-kill formula also kills weed roots, so its stated action extends beyond visible foliage. Its label lists more than 460 weeds and identifies bluegrass, fescue, zoysia, Bermuda, and perennial ryegrass as treatment locations, helping buyers check lawn compatibility. The ready-to-spray 32-ounce product removes the need to mix a separate concentrate. Apply only within the stated 45–90°F daytime range, and wait three to four weeks after application before reseeding.

Skip it if you want to treat flower beds or walkways; Roundup Weed & Grass Killer4 lists landscape and hardscape areas for use.

Choose this for a lawn owner who values a stated three-hour visible-results window and needs a product labeled for several grass types. Check the specific grass and temperature directions, and plan around its reseeding interval.

#3 · Root-Targeting Lawn Spray

3. Ortho WeedClear Ready-to-Use

• Form: Liquid

Best for: Ready-to-use lawn spot treatment.

Why it ranks #3: The ready-to-use formula targets dandelions and other listed weeds down to the root, with a Comfort Wand and a claim of results from one application.

The ready-to-use Comfort Wand pairs direct application with a formula that kills listed lawn weeds down to the root. For dandelion and crabgrass spot treatment, it avoids a separate mixing step while identifying lawn grasses that can be treated when directions are followed.

Ortho lists dandelion, clover, chickweed, creeping charlie, and crabgrass among its targets, with more than 200 major broadleaf and grass weeds covered. The formula is stated to kill listed weeds to the root and deliver results with one application, which suits buyers seeking a targeted lawn treatment. The use information names northern lawn grasses including Bermudagrass and Buffalograss. As with any selective lawn treatment, follow label directions to avoid harming grass or contacting desirable plants.

Skip it if you want a small trigger bottle for occasional individual weeds; Scotts TouchUp Weed Control is a 24-ounce ready-to-use spot spray.

Consider it for lawn owners who want ready-to-use wand application against listed weeds such as dandelions and crabgrass. Its stated grass-use information is specific, so check the product label for your lawn type before treatment.

#4 · Compact Spot Treatment

4. Ortho Weed B Gon

• Weight: 1.5 lb
• Form: Spray

Best for: Compact trigger lawn spot treatment.

Why it ranks #4: This 24-ounce ready-to-use spray targets dandelions, clover and other broadleaf weeds in lawns, making it suited to treating individual weeds.

The 24-ounce ready-to-use trigger format lets Ortho Weed B Gon target lawn dandelions without a mixing or hose-connection step. It is stated to kill more than 250 listed weeds to the root while not harming the lawn when used as directed.

This spray is aimed at lawn weeds including dandelions and clover, with results stated in hours and root-kill action. The ready-to-use trigger format supports individual spot treatment, making it a practical choice when weeds are scattered rather than spread across a large area. The product’s lawn-safety claim depends on following directions; its safety information also says not to use on or near desirable plants and to keep people and pets away during use.

Skip it if you need to treat a larger lawn area through a hose-end applicator; Scotts Liquid Turf Builder with Plus 2 Weed Control uses that format.

A good match for targeted lawn treatment of scattered dandelions and other listed broadleaf weeds using a compact trigger bottle. Keep the spray away from desirable plants and follow directions to protect lawn grass and people.

#5

5. Scotts TouchUp Weed Control

• Weight: 1.8 lb
• Form: Spray

Best for: Individual lawn weed spot spraying.

Why it ranks #5: The 24-ounce ready-to-use spray specifically lists dandelion, clover and crabgrass, and is described as a lawn-safe option for spot treatment.

A ready-to-use 24-ounce spray bottle makes Scotts TouchUp a direct option for treating individual dandelions without preparing a lawn-wide application. Its listed targets include dandelion, clover, and crabgrass, and the product is described as not harming lawns when used as directed.

The spot-treatment focus suits isolated lawn weeds: aim at the center and lightly cover the target, holding the nozzle two feet or less away to limit drift. Because it is ready to use, the bottle can be taken directly to the weed rather than connected to a hose or mixed. The stated targets are dandelion, clover, and crabgrass. Keep it away from desirable plants, and note that the listing says it is not sold in Hawaii.

Skip it if you need to address more than a few individual weeds across a lawn; Ortho WeedClear Weed Killer for Lawns with Comfort Wand lists over 250 broadleaf weeds.

A straightforward fit for homeowners handling occasional dandelions, clover, or crabgrass in a lawn. Its spot-treatment format is less suited to broad coverage, and the listing excludes Hawaii; follow the close-range application directions.

#6 · Weed Control Plus Feed

6. Scotts Liquid Turf Builder Plus 2

• Weight: 8 oz
• Form: Spray

Best for: Lawn weed control with feeding.

Why it ranks #6: This hose-end spray combines listed broadleaf weed control with a quick nitrogen boost, fitting buyers who want weed treatment and lawn feeding together.

A quick nitrogen boost distinguishes Scotts Liquid Turf Builder with Plus 2 Weed Control from a weed-only spray, letting one hose-end application combine lawn feeding and listed weed control. Its 25-0-2 NPK specification makes the fertilizer component explicit for buyers planning lawn care.

The hose-end applicator attaches to a garden hose, so buyers can spray the lawn without separately applying a granular fertilizer product. Scotts states that the formula supplies nitrogen while targeting listed broadleaf weeds, including buckhorn and chickweed. Applying when weeds are actively growing supports the stated use directions. After application, do not water the treated area for 48 hours; weeds may begin curling within days, and hard-to-control weeds may require another application in three to four weeks.

Skip it if you want a non-selective spray for weeds on a driveway; Spectracide Weed & Grass Killer with AccuShot Power Sprayer lists driveways for use.

A sensible choice for lawn owners who want weed treatment and a nitrogen application in one hose-end workflow. It is not the pick for hardscape weed control, and the 48-hour no-watering instruction needs to fit your lawn-care schedule.

#7

7. Sunday Dandelion Doom

• Weight: 2.1 lb
• Form: Liquid

Best for: Concentrate-and-wand lawn kit.

Why it ranks #7: Its product name and listing identify it as a lawn weed killer concentrate, supplied with two bottles and a wand sprayer; the provided details are limited.

Two concentrate bottles paired with a wand sprayer give Sunday Dandelion Doom a refill-oriented kit format for lawn weed treatment. The product is identified as a lawn weed killer concentrate, offering buyers a dedicated dandelion-focused option rather than a general weed-and-grass product.

The included components are two concentrate bottles, one pouch, and one sprayer, so the kit provides its own application hardware alongside the formula. The product information directs application when weeds are actively growing, a useful timing cue for planning lawn treatment. People and pets may re-enter once the spray has dried, while outdoor-only use and avoiding eye and skin contact are specified. The supplied details do not identify a weed count or grass compatibility list, so check the label for those specifics.

Skip it if you need a product with a stated weed list and grass types; Spectracide Weed Stop For Lawns Concentrate Ready-To-Spray provides both details.

This kit may suit lawn owners seeking a concentrate-and-wand package for dandelion control, especially when application hardware is useful. Check its label for target weeds, lawn compatibility, and mixing directions before treating.

#8

8. Spruce Weed & Grass Killer

• Weight: 5.4 lb
• Form: Multiple

Best for: Quick-results broad-spectrum spot spraying.

Why it ranks #8: This non-selective formula lists dandelions and claims visible results in one hour, but it is not the lawn-selective choice for preserving grass.

Visible results in one hour give Spruce Weed & Grass Killer3 a fast stated feedback window for treating dandelions and other weeds. The ready-to-use kit includes a power wand and two AA batteries, supporting spray application without preparing a separate mixture.

Spruce describes a non-selective formula that dehydrates weeds to kill roots, with dead weeds stated in one day. Its target list spans broadleaf and grassy weeds, including dandelions, large crabgrass, white clover, dollarweed, and morning glory vines. One bottle can treat up to 400 weeds, which gives buyers a stated coverage measure. Use it at first growth on a calm, dry day above 60°F, with no rain forecast for 24 hours; avoid desirable plants.

Skip it if you need to kill dandelions without harming lawn grass; Ortho WeedClear Weed Killer for Lawns with Comfort Wand is labeled lawn-friendly.

Best suited to buyers treating weeds where surrounding vegetation can also be killed, who value a power wand and quick visible results. Because the formula is non-selective, keep it off grass and desirable plants you intend to preserve.

#9

9. Roundup Weed & Grass Killer4

• Weight: 8 oz
• Form: Spray

Best for: Landscape-edge weed treatment.

Why it ranks #9: It lists dandelion among weeds killed to the root and includes a Pump 'N Go sprayer, but it also kills grass and is not lawn-selective.

Rainproofing in as fast as 30 minutes makes Roundup Weed & Grass Killer4 useful when a short weather window matters. Its Pump ’N Go 2 sprayer accompanies a non-lawn weed-and-grass treatment for dandelions and other listed weeds around landscape beds, patios, and driveways.

This product kills weeds and grasses to the root, including dandelions, crabgrass, poison ivy, and clover, making it suitable for listed areas where grass preservation is not the goal. The use list includes flower beds, perennial landscape plants, trees, shrubs, patios, walkways, driveways, and gravel. Rainproofing in 30 minutes can reduce weather-related disruption, while planting may be possible one to 30 days after application according to the booklet. Wait until spray dries before re-entry.

Skip it if you need to preserve lawn grass while treating dandelions; Ortho WeedClear Weed Killer for Lawns with Comfort Wand is labeled lawn-friendly.

A fit for buyers clearing dandelions and other listed growth around hardscape or landscape areas, rather than selectively treating a lawn. Check the planting interval in the booklet and keep people and pets away until the spray dries.

#10

10. Spectracide Weed & Grass Killer

• Weight: 12.3 lb
• Form: Spray

Best for: Extended-wand hardscape spraying.

Why it ranks #10: This non-selective spray includes an extendable AccuShot wand and claims results in three hours, but its listed uses are not lawn-selective dandelion control.

The AccuShot continuous power sprayer has an extendable wand, enabling directed application across listed weed-prone areas without relying on a short-reach spray head. Spectracide targets weeds and grasses to the root and states visible results in as little as three hours.

Its use list covers driveways, walkways, fences, trees, flower beds, shrubs, and other listed areas, making it a fit for clearing growth beyond a lawn. The extendable wand supports aiming, while the continuous power sprayer helps maintain application over those areas. Rain or watering 15 minutes after application will not wash away effectiveness, and the product states that new flowers, trees, and shrubs can be replanted the same weekend. Protect desirable plants during spraying.

Skip it if you need a selective lawn spray for dandelions; Spectracide Weed Stop For Lawns Concentrate Ready-To-Spray is labeled for lawns.

A practical option for clearing listed weeds and grasses around walkways, fences, beds, and trees with an extendable wand. It is non-selective, so avoid spraying lawn grass or other plants you intend to keep.
