I do not use it full strength either. It would just be a waste if 20% does the job! I am going to put some into my gallon hose sprayer next weekend when I am off and spray everything real good even the soil and then do lime the next morning and hose it down that evening. I will let you know how it goes, but I still keep the bottle by the door in garage in case I see one crawling around. Remember...''never let a slug get away!" LOL.
