BioAdvanced Extreme Crabgrass Killer is a specialized crabgrass solution that kills down to the root. The exclusive formula kills even large, hairy and smooth crabgrass. In addition to fighting off crabgrass, it kills grassy weeds including foxtail, sandbur, bermudagrass, and more. For best results, apply at the first sign of weeds and when temperatures are below 90 degrees. It can be used on Northern turfs such as Fescue, Perennial Ryegrass, and Kentucky Bluegrass. It is NOT intended for use on St. Augustine, Floratum, Bermudagrass, Bentgrass, Zoysiagrass, Centipede or Bahia lawns. The product is rainproof in just one hour after application, meaning no rain or water will impact the effectiveness of the formula. BioAdvanced Extreme Crabgrass Killer measures 32-ounces and treats up to 5,000 square feet.

For additional information on this product, please see the Product Documents section for all downloadable user manuals, installation guides, brochures and warranty statements.

Great

a month ago
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

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!

7 months ago
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.

7 months ago
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.
