This grub killer also kills caterpillars (armyworm), chinch bugs, May/June beetles, and more (as listed), and can help control Japanese beetle infestations when applied annually.

    Use the brand Bio Advanced 24 hour grub killer. It’s kind of hard to find.

      Hello! Grubs hatch around June and feed all through the summer before going dormant in the Fall. They then rise up near the surface again around April-May and pupate. Because of this cycle, for the very best results when using GrubEx1 to control most grubs, it needs to be applied in May before the target beetle eggs are laid. In the meantime your best bet is to feed and seed your lawn to build strong roots for Spring growth. For the best recommendation on what products to use to feed and seed your lawn, we can be reached at 800-543-8873. We are available 8am - 8pm EST Monday - Friday, and 8am - 5pm EST on Saturdays. We look forward to assisting you.

        Can this product be used now, late summer to stop the damage to the lawn from chinch bugs?

        For the very best results when using GrubEx1 to control most grubs it needs to be applied in May before the target beetle eggs are laid. This product will only suppress chinch bugs, but not control them. For product recommendations that will control chinch bugs, please reach out to speak with an agent at 888.270.3714.

              Will it work in late August

              Answer This Question

              For the very best results when using Scotts Grubex1 Season Long Grub Killer, it needs to be applied in May before the target beetle eggs are laid. If applied too late, (late summer and fall) the grubs will be too large to be controlled. Larger (mature) grubs are not susceptible to most pesticides.

                    Applied in Spring. Can conditions come back after many HOT days we’ve had?

                    Answer This Question

                    For most listed insect larvae, including grubs, and most areas of the country we recommend a mid-May through June application. The timing of the application is the important part as this product can only be applied once per year.

                      These grubs are killing me. I am not sure if it was just to late to apply but these grubs tore up my yard. I have to give it a two as it seemed to do nothing at all. I am a fan of Scotts products but I honestly cant say this product helped at all.

                      We're sorry to hear that you were disappointed with the Scotts Grubex1 Season Long Grub Killer.

                      For the best results apply prior to Memorial Day to make sure the active is washed into the soil prior to grubs hatching.
                      It can be applied in June or July per label but may not get into the soil to effectively control the early hatched larvae/grubs.

                      We value your feedback and are eager to learn more about your experience so we can improve. Please contact us at 877-220-3089 at your convenience.

                      We look forward to hearing from you and working towards a better experience. Scotts

                          Season-Long Protection You Can Trust
                          Coverage was even across my lawn and gave me confidence that the product was reaching the areas that needed protection. The efficacy has been excellent, with year-after-year results against grubs and other lawn pests. I was pleased that there was very little residue left behind after the following day rain. The application process was simple and easy to manage with my spreader. Absorption into the lawn was quick, and the product settled in well after treatment. Best of all, no lawn damage.

                            [This review was collected as part of a promotion.] This works wonders for the grass and kills all the bad eggs. This and was huge and covered a lot of ground. Affordable and was easy to wrap up if you don’t use it all.

                              It works!
                              It works! Last year my apple tree was COVERED with beetles all summer long and my lawn was destroyed. No matter where I dug on my yard, a few grubs came up. I spread this with grass seed earlier this spring and, while not totally eradicated, I have seen a huge improvement in both my lawn and the amount of beetles. A good reasonably priced solution and I will continue treating my lawn with it!

                                [This review was collected as part of a promotion.] I’m so glad I decided to put this all over my yard maintain it Appearance does not bother me. Not that noticeable texture is great results. I’ve been noticing that it’s been working. You just have to be consistent with it but overall works great, especially for the summer. Keep all the pest

                                    [This review was collected as part of a promotion.] It seems like it will work well. I definitely recommend this Grub killer for anyone with a lawn that suffers from this pesky issue it is easy to spread via spreading device, the package has instructions for spreading and storage so no guesswork there. Waiting for proper results due to the inclement weather in Chicago it is somewhat difficult to gage efficacy throughly just yet however there is slight progress. I will be repurchasing once I have finished the bag.
