    4 of 5 Stars  Killzall
    By Gerald on June 10, 2011

    I have been using this product for a few years. It works slowly (4-6 days) to really see benefit but sprayed area lasts pretty well. The best thing is that you need only use 5 tablespoons to gal of water. Will kill everything.

    5 of 5 Stars  Killzall weed and grass
    By Frank on May 6, 2011

    A little slow in killing but most effective. Took about five days to kill all in the area that was sprayed. I did not see any affects of runoff from rain to surrounding plants or shrubs.

    5 of 5 Stars  Killzall Weed and Grass Killer
    By John on March 7, 2012

    I've been using this product now for several years. If you want to kill something green, this is the product. Just follow the directions and be very careful that you only put it on what you are trying to kill. It has helped me in removing vines/ivy that had been growing for over 15 years; from my home as well as choking 4 of my Oak trees. Since it is not available at any local stores, I was fortunate in finding DoMyOwnPestControl.com. A great company with super prices and fast shipping. And no, I'm not an employee. I do feel that good companies and products should get the cudos they deserve. Both apply here.

  • 5 of 5 Stars  Does What It Says
    August 30, 2013

    Just follow the instructions, and it will kill pretty much anything you spray. I found Ivy a bit resistant, but it still gave it some serious hurt. I had some very nasty prairie type weeds. They are history! Now maybe my grass can take over. You do have to have some patience as this does not work overnight. Up to 7 days before you start seeing results. 2.5 ounces per gallon goes a long way. I only ordered a quart, and still have half a quart left. Overall, very happy. For once I ordered something that did what it said it would do.

    5 of 5 Stars  Killzall Weed and Grass Killer - 41% Glyphosate - 2.5 Gallon
    August 26, 2013

    I have used this product for several years and a recent move brought about fears of not being able to find it. When I found your web page it was a ray of sunshine. This is one of the few products I have found that works EXACTLY as it says it will. I apply it over a large area with a hose-end sprayer and the weeds are gone for several months - not forever but the time period makes it worth the effort.

  • 5 of 5 Stars  Does exactly what it says it does
    August 24, 2013

    Anyone leaving a negative review, was too stupid to follow directions. This is not an Instant Killer. All you have to do is follow directions. This stuff works. Patience is what you need. I had a very tough yard to deal with. I read a lot of reviews---product came through. Patience. patience patience. It killed even my toughest weeds. Prairie wild kind of weeds. Surpassed my expectations. two weeks for total kill, but better than anything else. Hope it is always available. Only ordered a quart--still have half a quart left. Totally erradicated my problems. Now the good grass can take over. yeah, I was skeptical, but trust me, this stuff works.

    5 of 5 Stars  Everything is dead
    August 18, 2013

    When I put down this Killzall it was not supposed to rain at all for the next week. The internet told me so and so did my local weather man. Like usual they were wrong and it proceeded to rain for the next 2 day after I applied this product. In about 7 day from when I first applied the product my weeds are dead, not kinda dead, but dead dead. I was surprised I did not have to go and respray. This product is awesome and I recommend anyone who wants to kill weeds/grass to give this a try.

QDoes Killzall loose any of its potency after it has been in sub-freezing temperatures for the winter?

AIt is not recommended to leave any type of chemical in areas where they could freeze or over heat because of the potential for the chemical to break down. According to the manufacturer, as long as the Killzall Weed and Grass Killer was only exposed to sub freezing temperatures for a short period of time and the product looks exactly the same as before it was exposed, it should be fine.

June 20, 2013 George from Huntersville, Nc asked:

QIf I mix more Killzall than I use, what is best way to store it?
My Stihl backpack sprayer sepcifically says to empty it after spraying, rinse it, and let it dry. I destroyed another, less expensive sprayer by leaving mixed Killzall in it. Would a plastic gas can withstand the prolonged exposure. I can't always predict how much mixed Killzall I'll need, and I don't want to just waste it.

A The recommendation for not leaving mixed solution in your sprayer is not only because it can damage your sprayer, but the solution is not good if left mixed more than 48 hours. Any time you spray you should only be mixing what you will use for that treatment and no more. Anything left over should be disposed of in the proper manner for that product, so if you have to, mix up less than you think you will need to avoid waste.

QWill Killzall offer a full year kill?

A Killzall Weed and Grass Killer contains glyphosate and will only kill the plants you spray it on directly and it does not leave behind a residual to kill future plants. To stop future plants from growing you will need to use a pre-emergent herbicide that is labeled for the target plants or a soil sterilent which makes the uninhabitable for most plants.
