Hi Dell, In the US the concentrated form is "Bayer Advanced Garden Tree and Shrub Insect control" with 1.47% Imidaproclid, which sounds dilute but must be further diluted.. There is also a ready to us spray form with a diluted concentration. The concentrate is better as you can make up soil drenches etc. There is enough there to share with all your neighbors. It is the same chemical as is used in Advantage flea control for cats.
