10 Best Crabgrass Killers 2025 in the United States

BASF Drive XLR8 Crabgrass Herbicide is a liquid herbicide aimed at eliminating crabgrass and other weeds. The active ingredient in this product is a potent herbicide, which ensures effective weed control. This product comes in a 64-ounce container, which provides broad coverage for large lawn areas. The application method is straightforward, typically requiring a sprayer for even distribution across the lawn. However, it's worth noting that using a sprayer might require some additional tools if you don't already have one.

As a non-selective herbicide, it targets a wide range of weeds, which can be beneficial if your lawn is heavily infested, but you'll also need to be careful to avoid desirable plants. In terms of lawn compatibility, it works well on established lawns but may not be suitable for newly seeded areas. The environmental impact is a consideration, as chemical herbicides can influence surrounding plant life and water sources if not used responsibly.

Despite these concerns, its ease of use and effectiveness make it a good option for those dealing with persistent weed problems, especially crabgrass. Sold on Amazon, it's easily accessible for purchase.

The Ortho WeedClear Lawn Weed Killer Concentrate is a liquid herbicide designed to tackle crabgrass, dandelions, clover, and other common lawn weeds. It works quickly, showing results after just one application by killing weeds down to their roots, which helps prevent them from growing back. This product is safe for use on many popular lawn grasses such as Bermudagrass, Kentucky Bluegrass, and Zoysiagrass, making it a versatile choice for various lawn types. Since it is a concentrate, it needs to be diluted properly before applying, which might require some care to ensure correct mixing. The manufacturer advises following the label instructions closely to avoid damaging your lawn.

It covers a large area (up to 5,000 square feet), which is convenient for medium to large lawns. The product has a solid reputation with a good customer rating of 4.1 out of 5. However, as with many chemical weed killers, there might be concerns about environmental impact and safety, so cautious use and adherence to instructions are important. For someone looking for a fast and reliable solution to common lawn weeds including crabgrass, this product does a good job but requires careful handling and proper application.

Scotts Halts Crabgrass & Grassy Weed Preventer is a pre-emergent weed killer designed to prevent crabgrass and other grassy weeds from germinating in your lawn. One of the standout features is its broad spectrum of effectiveness, targeting various weeds such as foxtail, spurge, and barnyardgrass, which makes it a reliable choice for homeowners looking to maintain a healthy lawn. It is suitable for all grass types, adding to its versatility, although it should not be used on Dichondra or Bentgrass. With a coverage of up to 10,000 square feet, this 20.12 lb bag offers good value for larger lawns.

A notable strength is its ease of application; you can apply it in early spring or fall, and it remains effective even after rain or frost, which can be a significant advantage for those who may not have ideal weather conditions.

On the flip side, while the product is effective, it is essential to apply it at the right time for maximum benefits, which may require some attention to local weather conditions and timing. Additionally, being a pre-emergent killer means it won't address existing weeds, so if you have crabgrass already growing, you'll need a different solution for that. The environmental impact is another consideration; some users prefer organic options, and while this product is effective, it does use chemical ingredients. Thus, it may not align with all users' preferences for eco-friendly lawn care.
