Ammonia ( the household liquid) is diluted ammonium hydroxide that when left to dry out lets loose ammonium molecules that are very volatile. Ammonium has bleached and killed my young tomatoes. It was produced unwantingly in a compost heap that was not securely sealed with soil and leaked into the general atmosphere of the greenhouse, thus affecting many plants. We learn't the hard way not to take any risk with ammonium. Meanwhile slugs kept on feeding on various plants next by. We still prefer to use commercial baits when it comes to maintain our ongoing commercial vegetable operation. Risk analysis is part of normal cost benefit logic.
