Imidacloprid is a very safe to use low toxic insecticide that was first introduced to the US in 1994, previously patented by Bayer and used in Confidor.

Safe to spray on your lawn and also your garden as there is only a short withholding period (3-7 Days). This is the latest product which Ausgro has released in a range of products designed to give effective plant protection with the least effect on the environment. Complete Lawn Grub & Beetle Killer is widely accepted to be one of the safest new insecticides for both people and the environment. You can now take care of your lawn and the environment.
