I've sorta been disappointed in the results of Round Up 365. I want something that kills and plant life for eternity. I'm not concerned
about anything but flat out killing everything that is living a few areas of my driveway, side of my garage and flower gardens. I am familiar how Round Up works. Somebody told me Killzall 365 was good stuff.
Do you want something that turns your place into a toxic hazmat indefinitely? or just specific plant? I think pouring enough of anything will kill everything for good forever (bleach, vinegar, engine oil, boiling water, etc). I'd be careful if you ever want to sell your house or let your children inherit it though.
