of 1 ½ Cups Ammonia - it comes in various strengths.

I only see one strengths at the grocery store. It just says "Great Value" by Walmart.

Hi, Do you spray on the dirt or on the snail itself The ones I have are the small hard-shell kind and they come out at night and hide in the daylight. I only have my plants in large pots but they still find them, Now and then I'll find them eating on the leaves. Will this still work? I'll try anything once. Thanks, Alda

" Overspray any location where you see the usual signs of slug activity (the soil, the pot, the ground). Also spray directly onto the slugs (yes spray the snail or slug) if you are out in the evening checking on your flowers, shrubs, seedlings, and garden produce."

Another thing is plan old sand. Snails and slugs will not cross it. The spray will kill them and the sand will keep them from getting to the plant in the first place. Hope that helps!
