What Customers Are Saying

The Bayer Extreme Crabgrass Killer appears to be an effective product for controlling crabgrass and other weeds in lawns. It effectively kills crabgrass and weeds like Japanese stiltgrass, with most customers seeing results within 1-2 weeks of application. The product is easy to apply with a ready-to-spray hose attachment. While some customers saw immediate results, others noted it takes time for the crabgrass to fully die off, and reapplication may be needed for mature or heavy infestations. The product does not harm the surrounding grass and is safe to use around the home. Overall, the product seems to be a reliable and effective solution for controlling crabgrass, as long as the instructions are followed closely.

Great

[This review was collected as part of a promotion.] Smell horrible but does the job perfectly. I feel like this item works better than big brand at home improvement stores. Dry and die quickly. Doesn’t need much for it to makes the difference

Works

[This review was collected as part of a promotion.] Used this and it works to kill crab grass but you need to apply it several times. It’s easy to use, just attach the water hose and it’s ready to go. The only think I didn’t like was the smell.

Makes yard work so much less stressful!

[This review was collected as part of a promotion.] The Bayer Extreme Crabgrass Killer Ready to Spray is super easy to use and really effective! 🌱 I noticed a big difference in just a few days—crabgrass started dying off without harming the rest of my lawn. Makes yard work so much less stressful!

Glad I didn’t waste anymore of my money.

I’m glad I didn’t purchase any more of this product as I am very disappointed in the results. I purchased this and waited a few days until weather conditions were optimal. Followed the instructions explicitly and waited. Applied to our front yard and waited for results. It’s been 15 days and we have yet see any difference in the yard compared to areas which were not treated.

I was looking forward to using this product but found it to be a useless waste of time. It did not even turn the crabgrass blades a little yellow, let alone kill it.

Kills crabgrass and weeds

[This review was collected as part of a promotion.] I tried this product for my honest review. I tried it recently on my lawn as we’ve been getting lots of weeds and crab grass. We’ve been trying everything to get rid of it, but nothing really seems to be working so thankfully when I got this, I tried it on everything. It was very easy to use and I saw the results within a few days. I’m very happy with this product.

Effective on weeds

[This review was collected as part of a promotion.] UPDATED: this product did not work on our yard at all, we saw immediate crabgrass and weed growth. We would not purchase. So far, the rating for this product is based on ease of use and packaging. We put this all over our yard this past week and it was extremely easy to use / safe to use. There was no extra potent scent or anything of that nature. I will say that based on the size of our yard, we did end up using the entire bottle in one roun...

Great weed killer

[This review was collected as part of a promotion.] I think this product works and will be more dedicated about its use this year. My neighbor was disciplined about its application now he has a stellar looking lawn. I've used this product a few times in the past and the weeds went away temporarily. But they came back and I didn't reapply. My lawn is weed ridden. My neighbor, on the other hand, put down multiple applications of this product and now has his weeds under control. I have been very sp...

Effective Crabgrass Control

[This review was collected as part of a promotion.] I received a bottle of Extreme Crabgrass Killer-32 oz. Ready-To-Spray in exchange for my honest review. I felt the spray worked fairly well on my small lawn. I don’t have an invasion of crabgrass, so I only sprayed a few spots. The product does have a light scent. It’s not terrible. One bottle is enough for a 5,000 square foot yard. That amount would last me for a while. You attach it to a hose and spray…no mixing. Overall, I’d recommend the p...

Ok

[This review was collected as part of a promotion.] I received this item for free in exchange for my honest review. Overall, all this product worked OK. Our poor yard has been taken over by crabgrass after not being well-maintained last year and we applied two or three applications of this. It took care of some of the crab grass, but some of it honestly was completely resistant. We had to pull a bit of it up even though we’ve used this a few times and waited over two weeks. You also need to b...

Hoping it gets rid of crabgrass

[This review was collected as part of a promotion.] This product is specifically for use on cool season grasses, including fescue, Kentucky bluegrass and perennial ryegrass. Do not use it on centipede or Bermudagrass unless you're trying to kill it. Also, don't apply it when temperatures get above 90°. To use, you just need to connect the water hose to the bottle and spray all over the yard. It's easy to use, but make sure you keep pets and children off your yard after you spray it.

[This review was collected as part of a promotion.] The bioadvanced extreme crabgrass killer is the only thing that works on our grass in our region. I have tried all different brands and even professional landscaping companies to get rid of the patches of crab grass we have, but the only thing that has worked and worked fast is this.

[This review was collected as part of a promotion.] As it is winter where I am at when I receive this. And there is no to very little crab grass alive right now. However, last summer I did purchase a product very similar to this one and It did work so I am optimistic for this to work. As I have a ton of crab grass that has been annoying to deal with.
