Hunt around and find the "Bayer Advanced Tree and Shrub". Active ingredient on the front of the bottle will say "Imidacloprid - 1.47%"
Use 4.3 ml per 10 lbs of dogs weight from the base of the neck to the tip of the tail once a month when having flea/tick probs. You'll be using and dosing the exact same as you would be using Advantage.
This is what i use and it covers me for almost a year per treatment.
