Best Crabgrass Killer For Lawns: Compare 10 Options

Best Crabgrass Killer For Lawns

A strong crabgrass killer for lawns should match the weed’s growth stage, your grass type, and whether you want liquid or granular application. BASF Drive XLR8 Crabgrass Killer is the strongest fit for treating actively growing crabgrass after it appears, with a water-based concentrate and up to 30 days of residual control. For prevention, Scotts Turf Builder Halts Crabgrass Preventer with Lawn Food and Preen Lawn Crabgrass Control offer granular options designed to stop crabgrass before it takes hold.

This roundup compares ten products, including selective lawn treatments, broad-spectrum weed killers, and pre-emergent preventers. Check each label for approved grasses, application timing, and restrictions before choosing: a product that controls crabgrass may not suit every lawn or stage of growth.

BASF Drive XLR8 Crabgrass Killer is the best overall choice for a lawn with actively growing crabgrass. It is a post-emergent concentrate with quinclorac, a water-based formulation, and up to 30 days of residual control; the listing also says it is rainfast in less than an hour. Choose a preventive granular product instead if crabgrass has not emerged.

Always verify the label’s grass compatibility and directions before applying, since the right choice depends on lawn type and timing.

Detailed Reviews: Best Crabgrass Killer For Lawns

BASF Drive XLR8

#1 · Best Overall

1. BASF Drive XLR8

  • Weight: 4.2 lb
  • Form: Liquid

Best for: Fast-uptake post-emergent control.

Why it ranks #1: Its quinclorac concentrate targets emerged grassy weeds, offers up to 30 days of residual control, and is rainfast in less than an hour.

Its water-based formulation supports faster plant uptake, giving lawn owners a post-emergent option for grassy and broadleaf weeds. BASF Drive XLR8 uses quinclorac and offers up to 30 days of residual control, with rainfastness in less than an hour after application.

The water-based liquid formulation is identified as supporting faster uptake, which suits buyers treating weeds already present rather than relying only on prevention. Quinclorac provides grassy and broadleaf weed control, while the stated residual period of up to 30 days may reduce how often another application is needed. Rainfastness in less than an hour can also help when weather threatens to interrupt a treatment schedule. This is a concentrate, so application involves mixing rather than using a ready-to-spray product.

Pros
  • Water-based formulation supports faster plant uptake
  • Post-emergent control targets grassy and broadleaf weeds
  • Up to 30 days of residual control
  • Rainfast in less than an hour
Cons
  • Concentrate requires mixing before application.

Skip it if you want a granular crabgrass preventer with lawn food; Scotts Turf Builder Halts combines prevention and fertilizer.

Choose this concentrate if you need post-emergent control for lawn and turf weeds and value a short rainfast window. Its liquid concentrate format means you should be prepared to mix it before use.

BioAdvanced All-In-One

#2 · Broadleaf and Crabgrass

2. BioAdvanced All-In-One

  • Weight: 2.7 lb
  • Form: Spray

Best for: Broad-spectrum hose-end treatment.

Why it ranks #2: The concentrate controls crabgrass and more than 200 listed broadleaf weeds, works down to the roots, and is rainproof in one hour.

Control of more than 200 listed broadleaf weeds is the defining reach of BioAdvanced All-In-One, which also targets crabgrass. Its concentrate is applied by connecting it to a garden hose, and the formula is rainproof in one hour when used as directed.

The all-in-one formula combines control of crabgrass with more than 200 listed broadleaf weeds, making it relevant when a lawn has mixed weed problems. The product is described as penetrating weeds down to the roots, rather than only addressing visible growth. Hose connection is specified for application, providing a direct application workflow for the concentrate. Its one-hour rainproof claim gives a defined window before rainfall or watering, while application directions also specify temperature limits and actively growing weeds.

Pros
  • Controls crabgrass and over 200 listed broadleaf weeds
  • Formula penetrates weeds down to the roots
  • Connects to a garden hose for application
  • Rainproof in one hour
Cons
  • Application is limited by the listed temperature directions, especially for Bermudagrass.

Skip it if you need a granule applied with a spreader; Scotts Halts Crabgrass & Grassy Weed Preventer is a granular prevention option.

This fits lawn owners addressing crabgrass alongside a broad range of listed weeds who want hose-connected application. Follow the label's temperature directions, including its lower limit for Bermudagrass.

3. Preen Lawn Crabgrass Control

  • Weight: 15 lb
  • Form: Granule

Best for: Broad grass compatibility.

Why it ranks #3: This 15-pound granular treatment covers 5,000 square feet and offers prevention plus control of seedling crabgrass after emergence.

Coverage across listed cool- and warm-season grasses makes Preen Lawn Crabgrass Control an option for a varied range of established lawns. Its granular formula prevents crabgrass and more than 40 common lawn weeds, and can control seedling crabgrass for up to four weeks after emergence.

Preen combines pre-emergent prevention with limited post-emergent control, so it can address crabgrass before germination and seedlings for up to four weeks after emergence. The label lists many cool- and warm-season grasses, including Kentucky bluegrass, fescue, bermudagrass, and St. Augustinegrass, giving buyers a broad stated compatibility range. Granules are applied with a drop or rotary spreader, making this a spreader-based lawn-care task. The 15-pound bag covers 5,000 square feet.

Pros
  • Prevents crabgrass and more than 40 common lawn weeds
  • Controls seedling crabgrass up to four weeks after emergence
  • Listed for cool- and warm-season grasses
  • Covers 5,000 square feet
Cons
  • Granules require a drop or rotary spreader for application.

Skip it if you want liquid concentrate applied through a garden hose; BioAdvanced All-In-One specifies hose-connected application.

Consider this for a lawn within its listed grass types when you want both prevention and a short window of seedling control. Application requires a drop or rotary spreader, and coverage is 5,000 square feet per bag.

Roundup Crabgrass Destroyer2

#4 · Grassy Weed Specialist

4. Roundup Crabgrass Destroyer2

  • Weight: 5 lb
  • Form: Liquid

Best for: Established fescue and bluegrass lawns.

Why it ranks #4: It targets crabgrass and listed grassy weeds to the root, with use specified for Kentucky bluegrass, fine fescue, perennial ryegrass, and tall fescue.

Root-level control of crabgrass and grassy weeds is the central promise of Roundup for Lawns Crabgrass Destroyer2. Its listed application grasses include Kentucky bluegrass, fine fescue, perennial ryegrass, and tall fescue, giving buyers a defined compatibility range.

This liquid targets actively growing crabgrass and other grassy weeds, with early growth stages specified for best results. Its listed suitable grasses—Kentucky bluegrass, fine fescue, perennial ryegrass, and tall fescue—help buyers assess whether their lawn fits before application. The directions specify daytime temperatures between 45°F and 90°F. Rain should not be expected within 24 hours, and the product must not be reapplied within three weeks, so weather and follow-up plans matter.

Pros
  • Kills crabgrass and grassy weeds to the root
  • Targets listed grassy weeds including foxtail and goosegrass
  • Lists four suitable lawn grass types
  • Liquid formula treats actively growing weeds
Cons
  • Rain must not be expected within 24 hours after application.

Skip it if you need broadleaf weed control alongside crabgrass; Spectracide Weed Stop for Lawns Plus Crabgrass Killer lists both weed types.

Choose this liquid for actively growing crabgrass and grassy weeds when your lawn is among the listed grasses. Its 24-hour rain restriction and three-week reapplication interval require careful scheduling.

Spectracide Weed Stop

#5 · 470-Weed Coverage

5. Spectracide Weed Stop

  • Weight: 2.3 lb
  • Form: Liquid

Best for: Wide-ranging lawn weed control.

Why it ranks #5: This concentrate controls crabgrass and more than 470 listed weeds, with application recommended when temperatures are 45 to 90 degrees Fahrenheit.

Control of more than 470 listed weed types, including crabgrass, gives Spectracide Weed Stop broad reach for mixed lawn infestations. The concentrate is rainproof after three hours, and its directions call for application when temperatures are between 45°F and 90°F.

This liquid concentrate targets crabgrass alongside listed broadleaf and grassy weeds such as dandelion, chickweed, clover, and yellow nutsedge. That breadth can suit lawns where crabgrass is only one of several problems. The product is described as not harming the lawn when used as directed, and application is recommended when crabgrass first appears. Rain or watering three hours after treatment will not wash away effectiveness, creating a clear weather-planning interval.

Pros
  • Controls more than 470 listed weed types
  • Targets crabgrass, broadleaf weeds, and grassy weeds
  • Rainproof three hours after application
  • Lawn-safe when used as directed
Cons
  • Application to Bermudagrass may cause temporary yellowing or discoloration.

Skip it if you need to avoid any temporary Bermuda discoloration; ferti-lome Weed-Out lists Bermuda use but also notes possible temporary yellowing.

A fit for lawn owners treating crabgrass together with a broad mix of listed weeds. Respect the 45°F to 90°F application range, and account for possible temporary discoloration on Bermudagrass.

Fertilome Weed-Out

#6

6. Fertilome Weed-Out

  • Weight: 2 lb
  • Form: Liquid

Best for: Broad-spectrum concentrate for lawns.

Why it ranks #6: The concentrate controls more than 200 grassy and broadleaf weeds, including crabgrass, and its listing states one pint covers up to 2,500 square feet.

Control of more than 200 grassy and broadleaf weeds gives ferti-lome Weed-Out a broad role that includes crabgrass and foxtail. The concentrate treats up to 5,000 square feet per 32-ounce bottle and is listed for established lawns, including Bermuda and Kentucky bluegrass.

This selective liquid concentrate combines control of grassy and broadleaf weeds, including crabgrass, barnyardgrass, foxtail, and dandelion. Its stated coverage of up to 5,000 square feet per bottle helps homeowners plan treatment for a defined lawn area. The listed use on established lawns includes Bermuda, Buffalo, and Kentucky bluegrass, among other grasses. For best results, the supplied facts recommend spring or early summer application while weeds are small and actively growing; Bermuda may temporarily yellow or discolor.

Pros
  • Controls more than 200 grassy and broadleaf weeds
  • Treats up to 5,000 square feet per bottle
  • Listed for established lawns including Bermuda and Kentucky bluegrass
  • Spring or early-summer application targets small, actively growing weeds
Cons
  • Application to Bermudagrass may cause temporary yellowing or discoloration.

Skip it if you need a rainproof interval of one hour; BioAdvanced All-In-One Lawn Weed and Crabgrass Killer states that timing.

Choose this concentrate for established lawns with crabgrass and other listed weeds, especially when treating small, actively growing growth in spring or early summer. Account for possible temporary Bermuda discoloration.

#7

7. Image Crabgrass Killer

  • Weight: 1.6 lb
  • Form: Liquid

Best for: Contact-action nutsedge control.

Why it ranks #7: This ready-to-spray lawn treatment targets crabgrass, nutsedge, and more than 100 other listed weeds, making it useful for mixed weed problems.

Contact action paired with root-level weed control gives Image Herbicide a dual approach for crabgrass, nutsedge, and other listed lawn weeds. The ready-to-spray liquid is identified for established lawns and is described as not harming grass when used as directed.

Image targets crabgrass and yellow and purple nutsedge, alongside dandelion, clover, and more than 100 other listed weeds. Its contact-starting action offers a visible-growth treatment approach, while the stated root kill addresses tough weeds beyond their surface growth. The ready-to-spray format avoids the concentrate-mixing step and is intended for established lawns. Buyers should match use to the listed lawn setting and follow directions, since the supplied description does not identify newly seeded grass as a use case.

Pros
  • Targets crabgrass and yellow and purple nutsedge
  • Lists more than 100 additional weeds
  • Starts working on contact and kills to the root
  • Ready-to-spray liquid for established lawns
Cons
  • Specified for established lawns, not newly seeded grass.

Skip it if you want a granular pre-emergent application; Scotts Turf Builder Halts Crabgrass Preventer pairs prevention with lawn food.

This suits owners of established lawns facing crabgrass, nutsedge, and broadleaf weeds who prefer ready-to-spray treatment. Its stated lawn-use fit is established grass, so it is not aimed at newly seeded areas.

Bug And Blade Drive XLR8 Kit

#8

8. Bug And Blade Drive XLR8 Kit

  • Weight: 5 lb
  • Form: Liquid

Best for: Drive XLR8 concentrate kit.

Why it ranks #8: The kit includes 64 fluid ounces of BASF Drive XLR8 concentrate and disposable boot covers, but its listed facts provide less application guidance than the original.

The two-piece kit pairs BASF Drive XLR8 concentrate with disposable boot covers, giving buyers the named herbicide and protective accessories together. The product title identifies it as a post-emergent quinclorac treatment with 30-day residual control for Bermuda, Zoysia, and Fescue turf.

This kit centers on BASF Drive XLR8 concentrate, identified in the title as a post-emergent crabgrass killer containing quinclorac. The same title states 30-day residual control and names Bermuda, Zoysia, and Fescue turf, which helps buyers assess its intended lawn fit. The included disposable boot covers add a handling accessory to the concentrate package. Because the supplied product information does not provide mixing or application directions, buyers should consult the herbicide label for those steps.

Pros
  • Includes BASF Drive XLR8 concentrate
  • Includes one pair of disposable boot covers
  • Identified as post-emergent crabgrass control
  • Title specifies Bermuda, Zoysia, and Fescue turf
Cons
  • Kit is a concentrate, not a ready-to-spray treatment.

Skip it if you need a ready-to-spray weed killer; Image Herbicide Crabgrass, Nutsedge, & Weed Killer is listed as ready-to-spray.

This kit fits buyers seeking Drive XLR8 for post-emergent crabgrass treatment on the named turf types, with boot covers included. Check the label for application details, since directions are not supplied here.

Scotts Turf Builder Halts

#9

9. Scotts Turf Builder Halts

  • Weight: 13.4 lb
  • Form: Granule

Best for: Spring prevention with lawn food.

Why it ranks #9: This granular pre-emergent prevents crabgrass and includes lawn food for a 5,000-square-foot area, but it is for prevention rather than emerged weeds.

Crabgrass prevention paired with lawn food gives Scotts Turf Builder Halts a dual role: it aims to stop crabgrass before it invades while feeding grass for a fast green-up after winter. Its granules cover a stated 5,000 square feet.

As a pre-emergent granule, this product is aimed at preventing crabgrass before it appears, rather than treating established weeds. The lawn-food component adds a feeding step to the same application, with the stated aim of supporting fast green-up after winter and stronger, deeper roots. Rain, snow, or freezing conditions after application are not said to affect performance. The product calls for rainfall or watering of 1/4 to 1/2 inch within two to three days for best results.

Pros
  • Prevents crabgrass before it invades
  • Lawn food supports fast green-up after winter
  • Granular formula covers 5,000 square feet
  • Rain, snow, and freezing conditions after application do not affect performance
Cons
  • Pre-emergent prevention does not serve as a treatment for emerged crabgrass.

Skip it if you need control after crabgrass emerges; Preen Lawn Crabgrass Control also offers limited post-emergence control of seedlings.

A practical fit for homeowners planning a spring application who want crabgrass prevention and lawn feeding together. It is not the choice for emerged crabgrass, and best results call for watering within the stated window.

Scotts Halts Preventer

#10

10. Scotts Halts Preventer

  • Weight: 9.6 lb
  • Form: Granule

Best for: Seasonal grassy-weed prevention.

Why it ranks #10: Its granular application prevents crabgrass germination when applied in spring, but it does not serve buyers seeking to kill existing crabgrass.

One spring application is intended to prevent crabgrass for the season, making Scotts Halts a straightforward choice for prevention-focused lawn care. Its granules also have a fall role against listed winter weeds such as poa annua, henbit, and chickweed.

The product is a germination preventer, so its practical role is stopping listed weeds before they establish rather than killing visible crabgrass. Spring application targets crabgrass and other listed problem weeds for the season, while fall use addresses winter weeds including poa annua, henbit, and chickweed. The granules can remain effective despite rain, snow, or freezing weather after application. However, the label restricts use on newly seeded lawns until after the fourth mowing, an important planning boundary.

Pros
  • One spring application prevents crabgrass all season
  • Fall application targets listed winter weeds
  • Rain, snow, and freezing weather after application do not affect performance
  • Granular format supports seasonal lawn application
Cons
  • Not for newly seeded lawns until after the fourth mowing.

Skip it if you need to treat crabgrass already growing; Roundup for Lawns Crabgrass Destroyer2 targets actively growing grassy weeds.

This suits owners planning seasonal prevention on established grass, with spring and fall uses for different listed weeds. Avoid applying to newly seeded lawns before the label's fourth-mowing threshold.

Why crabgrass treatment timing can make or break results

Timing is the key distinction between preventing crabgrass and treating plants that are already growing. Scotts Halts Crabgrass & Grassy Weed Preventer and Scotts Turf Builder Halts Crabgrass Preventer with Lawn Food are pre-emergent products: their listed purpose is to prevent germination, so they are not substitutes for a post-emergent treatment on visible crabgrass. BASF Drive XLR8 Crabgrass Killer, BioAdvanced All-In-One, and Spectracide Weed Stop are listed as treatments for existing weeds.

Preen Lawn Crabgrass Control is a notable in-between option, with pre-emergent prevention and control of seedling crabgrass for up to four weeks after germination. A common mismatch is buying prevention after crabgrass has grown beyond the stage the product addresses.

Identify whether you see emerging plants or are planning ahead, then follow the product label’s timing and application directions. Do not assume a product’s broad weed list means it handles every growth stage.

Check lawn compatibility before treating grassy weeds

A crabgrass treatment that targets grassy weeds can still have important limits on which desirable lawn grasses it can be used on. Roundup Crabgrass Destroyer2 lists Kentucky bluegrass, fine fescue, perennial ryegrass, and tall fescue as compatible grasses, a narrower set than Preen Lawn Crabgrass Control, which lists both cool- and warm-season grasses including Bermuda, St. Augustine, and zoysia.

Other products also include cautions: Fertilome Weed-Out says application to Bermudagrass may cause temporary yellowing or discoloration, and Spectracide notes possible temporary discoloration on Bermudagrass. A compatibility trap is choosing by the word “lawn” in a product name without checking your specific turf type.

Use the label’s complete grass list and restrictions rather than assuming all lawn products are interchangeable. Also distinguish a product’s control of grassy weeds from its safety on your own grass; these are separate questions.

How to Choose a Crabgrass Killer for Lawns

Treatment stage

Choose a product based on whether crabgrass has emerged or you want to prevent it. BASF Drive XLR8 Crabgrass Killer, BioAdvanced All-In-One, and Spectracide Weed Stop are listed for controlling existing weeds, while Scotts Halts Crabgrass & Grassy Weed Preventer and Scotts Turf Builder Halts Crabgrass Preventer with Lawn Food are granular pre-emergents. Preen Lawn Crabgrass Control spans both stages, with prevention and control of seedling crabgrass for up to four weeks after germination.

Buyers seeing established, actively growing crabgrass should favor a post-emergent option and follow its application directions. Buyers planning ahead should consider a preventer and apply it at the label-recommended time.

Do not treat these categories as interchangeable: preventing germination does not mean a product will kill mature crabgrass.

Grass compatibility

Check the listed grass types before applying any crabgrass product, because compatibility differs. Roundup Crabgrass Destroyer2 names Kentucky bluegrass, fine fescue, perennial ryegrass, and tall fescue. Preen Lawn Crabgrass Control lists a wider range of cool- and warm-season grasses, including Bermuda, St.

Augustine, and zoysia. Fertilome Weed-Out cautions that Bermudagrass may temporarily yellow or discolor, while Spectracide gives a similar caution for Bermuda.

Buyers with a grass type specifically named on a product label can compare products by their fit and restrictions; owners of warm-season lawns should pay particular attention to the stated cautions. Never infer that a treatment is safe for a grass simply because it is marketed for lawns. Confirm the full label before use.

Formula and application format

Choose liquid or granular treatment according to the product’s application method and the job you need done. BASF Drive XLR8, BioAdvanced All-In-One, and Spectracide Weed Stop are liquids or concentrates, while Preen Lawn Crabgrass Control and both Scotts preventers are granules. Image Crabgrass Killer is described as ready-to-spray, whereas other liquid options require preparation or a specified application method.

Granular choices may suit buyers planning a preventive lawn application, while liquid treatments suit buyers comparing targeted post-emergent weed control. Coverage also varies: Preen and Scotts Turf Builder Halts each list 5,000 square feet, while Fertilome’s listing states up to 2,500 square feet per pint.

Match the format and coverage to your application setup and lawn area, and use label directions for measuring and applying.

Which Crabgrass Killer Should I Choose?

For visible, actively growing crabgrass, choose BASF Drive XLR8, the top-ranked post-emergent concentrate with up to 30 days of residual control. If you want one product for crabgrass and a broad range of listed broadleaf weeds, BioAdvanced All-In-One controls more than 200 and is rainproof in one hour. For prevention with some flexibility after germination, Preen Lawn Crabgrass Control offers granular pre- and post-emergent control.

Choose Scotts Turf Builder Halts if you want prevention combined with lawn food; its listed coverage is 5,000 square feet. If your main concern is grassy weeds on one of its specifically named turf types, consider Roundup Crabgrass Destroyer2.

Whatever you select, confirm that your grass is listed, check timing and temperature restrictions, and follow the label.

Frequently Asked Questions

When should I apply crabgrass preventer in spring?

Apply a preventer before crabgrass emerges, following the product label for timing and conditions. If crabgrass is already visible and actively growing, a post-emergent treatment may be more appropriate. Check the label’s temperature restrictions and directions, and confirm that the product is compatible with your lawn grass before applying.

Can crabgrass killer harm my lawn grass?

Yes, a crabgrass treatment can harm lawn grass if the product is not compatible with your turf or is applied contrary to its label. Grass compatibility varies by product, so check the listed turf types, directions, and any temperature restrictions before treating. Do not assume a product is safe for every lawn.

Should I use a pre-emergent or post-emergent crabgrass treatment?

Use a pre-emergent when crabgrass has not emerged and you want prevention. Choose a post-emergent for visible, actively growing crabgrass, provided the product is labeled for your grass. Some products offer both types of control, so check the label and match the treatment to the weed’s growth stage.

What should I check before choosing a crabgrass product?

Check whether the product is intended for prevention or control of emerged crabgrass, then verify that your lawn grass is listed as compatible. Also review the application directions and temperature restrictions. If you want to address other weeds too, compare the product’s listed weed targets rather than assuming it controls them.

How long should I wait after applying before rain?

Follow the product label for rain guidance, because the instructions can differ among treatments. The BASF Drive XLR8 listing says it is rainfast in less than an hour, while the BioAdvanced listing says it is rainproof in one hour. Do not apply those claims to other products; check each label before use.

Final Words

For visible, actively growing crabgrass, BASF Drive XLR8 is the top-ranked post-emergent concentrate, with up to 30 days of residual control. If crabgrass has not emerged, choose a preventive granular treatment instead. BioAdvanced suits buyers seeking control of crabgrass and many listed broadleaf weeds, while Scotts Turf Builder Halts combines prevention with lawn food.

Before applying any product, confirm grass compatibility, timing, and temperature restrictions on its label.
