    Takes a while but very effective

    By Jason on 05/17/2024

    The first time I used this I thought it was not working. After a week, the weeds and grass looked healthier than ever. Did I accidentally spray fertilizer? However, after about 2 weeks everything I sprayed was dead, very dead. So, just be patient and it should kill anything green you sprayed.

    It took several days to work, but all the weeds and grass growing up through my gravel driveway are dead as a hammer now

    Title is fine

    By Cecelia on 06/28/2024

    It did not do as stated I mixed according to instructions with no results. I added more product to the mix and the results were very disappointing

    Absolutely in awe as to how well this worked. Within two days all weeds were gone. What an amazing find. So glad this just popped as I was looking for another product.

    Killzall

    By Susan on 08/23/2024

    Works great.. I do all the edges of my lawn so I don’t have to trim and get right up next to the fence or stone.

    Patience Pays Off

    By Aaron on 08/01/2025

    It took a little longer than I expected (a few days) to start showing an impact, but eventually within a week or so the Kilzall killed off most of the target plants that I'd sprayed. I didn't have 100% kill, but pretty good considering that I sprayed in non-ideal circumstances (mature crabgrass plants and very hot weather). I was pleased with the overall results.
