Grub Guard kills aphids, bugs, caterpillars and many other pests … and it’s the only product on the market that kills lawn grub larva. That means you can use it post attack from a host of pests and prior to an attack from grubs. Plus, Grub Guard is safer to use than any other pest control product. It contains the active ingredient Esfenvelerate, a broad-spectrum insecticide that’s toxic to most insects. Grub Guard 2L trigger-spray bottle treats up to 150m².
