I received AMDRO PowerFlex Pest & Weed System ,from BzzAgent .I used it in my yard for weeds and it worked great. I used it also for the ants and spiders, what ever other little pest might be lurking around. There is no mixing or mess the system uses cartridges that you screw on the sprayer and you put water in the jug. That is all there is to it. very easy to use.
