Thank you for this informative article. As you mention, nicotine, as found in tobacco, can and has been used as a pesticide - it is a neurotoxin to insects and humans. Nicotine solutions have been marketed for commercial use, so it's easy to see how someone might seek to elute it from cigarette tobacco and/or cigarette butts as a homemade concoction. Problem is, nicotine is easily absorbed through the skin, as well as via inhalation (in smoke or as an aerosol). So, as in this case, homemade does not equal safe. As a clinical toxicologist who has managed patients poisoned with nicotine solutions, this practice is potentially life-threatening and should be avoided.

I have been taking my bath water which contains soap and shampoo/conditioners and pouring it on the grass in an attempt to save my small lawn. It looks like it is not helping-grass is dying. Curious to get comments from others.

The insecticidal soap I make on my own for my roses has been phenomenal! It kills the aphids, the roses look great and are blooming like crazy. I think you have to be careful with articles like this - lots of good points but there's more to the story.

Very interesting. Too many people just want chemicals to solve their gardening issues. Everyone needs to share this kind of info.

More to the story: Anecdotal information, from one source, concerning one application, with no control, with no description of ingredients or proportions, should not trump science.
