The 3 Best Crabgrass Killers in 2021
Finding the suitable crabgrass herbicide is crucial if you want to treat your infested lawn.
Below, you’ll find some of the best crabgrass killers on the market today.
1. Tenacity Turf Herbicide – Best Overall
Often referred to as Tenacity, Tenacity Turf Herbicide has been considered one of the best crabgrass killers in the herbicide market for years.
It works both as a pre-emergence and post-emergence herbicide, which essentially means that it’ll take care of crabgrass creeping in your garden regardless of whether it has germinated or not.
Accordingly, if you apply Tenacity on crabgrass seeds, they’ll absorb the chemicals from the herbicide, halting their growth progress.
And a major plus for Tenacity Turf Herbicide is that, alongside being a crabgrass killer, it also deals with other intruding weeds, including dandelions, foxtails, and carpetgrass.
Not to mention, the herbicide is compact, but that means it runs out relatively fast.
- Works both as a pre-emergent and post-emergent
- Can deal with other stubborn weeds
- Easy-to-store, compact container
- Runs out quicker than other herbicides
- Tenacity is a systemic pre-emergence and post-emergence herbicide for the selective contact and residual control of weeds in turfgrasses.
The Tenacity Turf Herbicide is an all-around solid option if you want a herbicide that’ll get rid of your crabgrass, whether it has emerged or not.
The compact container can also be a plus when storing it at home.
2. Scotts Halts Crbgs Preventer – Runner Up
Similar to Tenacity, Scotts Halts Crbgs Preventer is also brought by a famous brand when it comes to killing crabgrass weed in lawns. It’s a durable option for you, and it’ll work seamlessly in sunny, rainy, and snowy conditions.

Factors to Consider When Buying a Crabgrass Killer
Before deciding on which herbicide you want, make sure you understand the nature of the crabgrass situation in your lawn. And we’re here to help you ask all the right questions.
Crabgrass Growth Stage
This is a crucial factor you need to consider before making your purchase. Based on whether the crabgrass seeds are emerging or have already emerged, you need to buy a pre-emergent herbicide or a post-emergent one, respectively.
There are various herbicides in the market, and all of them work for different sizes of lawns and treatment areas. Make sure that you’ve measured the total area of the land requiring treatment, so you can purchase the herbicide that fits your lawn size.
If you don’t want to spend much or want the best value out of your money, then we’d recommend going for a herbicide that is just enough to cover the grass area and is either a pre-emergent or post-emergent.
Ultimately, a proper crabgrass killer is necessary if you want your lawn to look neat and pleasant.
Of course, you can opt for any of our picks, but we can’t help but recommend the best herbicide, which is, in our opinion, Tenacity Turf Herbicide.
Operating as a pre and post-emergent, this crabgrass killer can eradicate even the most stubborn weeds!
