Combine ingredients in a spray bottle; squirt on slugs.

Reader Mary Jo Forbus of Arlington, Wa wrote: "A few squirts are all it takes; they die right before your eyes, a very gratifying sight! The mixture is harmless to soil and plants. I keep my spray bottle nearby when gardening and check the garden twice a day, once early in the morning and again late in the evening."
