10 Best Crabgrass Killers 2025 in the United States

The Ortho GroundClear Weed and Grass Killer is a versatile product designed to tackle various types of weeds and grasses, including dandelions, chickweed, moss, and crabgrass. One of its key strengths is its fast-acting formula, which shows visible results in just 15 minutes and becomes rainproof within 2 hours. This makes it a convenient choice for quick weed control in areas like patios, walkways, and driveways, as well as landscape beds. However, it's important to note that this product is not suitable for use on lawns or desirable grasses, which could limit its application if you need to protect your lawn while killing weeds.

Ease of use is another positive aspect, particularly if you have the Comfort Wand from the original container, allowing for precise targeting of weeds. The 1-gallon refill is substantial, covering a significant area and making it economical for extended use. However, always ensure that weeds are small, actively growing, and not wet to achieve the best results.

In terms of environmental impact, the product is OMRI (Organic Materials Review Institute) listed, suggesting it meets organic standards, which can be a reassuring factor if you're concerned about using chemicals in your garden. A drawback to consider is that the product's effectiveness hinges on proper application conditions, such as dry weather and active weed growth, which may require you to plan your usage accordingly. Additionally, the product's restriction to non-lawn areas means it might not be the best choice for those looking to address crabgrass specifically in their lawns. If you need a powerful and fast-acting solution for controlling weeds and grasses in specific areas around your home and are mindful of application guidelines, this product could be a strong contender.

The Roundup Dual Action Weed & Grass Killer Plus 4 Month Preventer with Sure Shot Wand is a versatile product designed to both eliminate existing weeds and prevent new ones for up to four months. This dual action is effective for areas like driveways, sidewalks, patios, and around well-established plants. The Sure Shot Wand provides precision in application, making it user-friendly and reducing the risk of harming nearby plants.

It works quickly, showing visible results in as fast as six hours and is rainproof within 30 minutes, adding to its convenience. However, its compatibility with lawns might be limited as it is primarily intended for hardscapes and landscaped areas. Additionally, it's important to consider the environmental impact, as herbicides can affect the surrounding ecosystem.

Users looking for a fast-acting and long-lasting weed solution will find this product valuable, but they should use it cautiously around desired plants and in alignment with local environmental guidelines.

The Spectracide Weed and Grass Killer Concentrate is designed for use on patios, walkways, and driveways, rather than lawns. This makes it ideal for users looking to clear weeds and grasses from hardscaped areas. Its fast-acting formula shows visible results within 3 hours, and its rainfast feature ensures effectiveness even after rainfall or watering 15 minutes post-application.

The concentrate form requires mixing and application with a tank sprayer, which may require additional effort and equipment, but allows for thorough coverage of target vegetation. This product is non-selective and broad spectrum, meaning it will kill a variety of weeds and grasses, not just crabgrass. However, it may not be suitable for use on lawns due to its non-selective nature, which could harm desirable grass and plants.

The ease of use is moderate given the need for a sprayer, but the visible results and effectiveness make it a strong option for those who need quick and reliable weed control on non-lawn surfaces. In terms of environmental impact, it is important to consider potential runoff and its effects on nearby plants and water sources.
