He sprayed it. How long should it take until it all grows back.
Killzall Weed and Grass Killer is a non selective herbicide, meaning it will kill whatever it comes in contact with weeds, grass, vines, etc. Applying it undiluted would be an off label use and could be very harmful to the areas its applied in that manner. Always follow the labeled instructions. If applied undiluted the residual in the soil is going to be longer than if applied correctly. It will remain in the soil for at least a month or so if applied undiluted. If this was done in your yard you will need to reseed to have anything grow back.
