Why such a weak solution of ammonia to water and WHY spray after dark. We use a much stronger solution and spray whenever we see them. I keep a spray bottle handy when I garden. Of course, I am going for a direct hit. Since I wear gloves while I garden, I just pull them off or throw them out on the lawn and then spray. Works for snails, too.
Never watering at night or evening is not an option here in Oregon. God does it, especially in the spring when slugs are hungriest.
Now I am going to look for the ingredient iron phosphate on my slug bait box that I just purchased. I am also going to check on my kohlrabi starts that I baited with the new box of bait. And I will take my spray bottle along, too. Armed and ready for war I go off to the spring garden.
Thanks for the great article. I really did like it.
Thanks tonileland for your answer. It's actually kinder to use a stronger solution, as they slim away faster. Yuk!! Anyway, hope you return to your native state someday. It is still the best one in my humble opinion, slugs and all. LOL
