Non-detergent soaps for homemade insecticide
I've been researching recipes for homemade insect repellents on this forum, and see that diluted non-detergent soaps are frequently used. I'm just looking for some actual brand-names of such soaps. I've read that Ivory is no longer non-detergent, and that Dr. Bronners, since it is made from vegetable sources isn't as effective as animal-derived fatty acids. So that leaves Fels-Naptha but I'm wondering if there are any others... and what about Murphy's Oil Soap? Is that too strong? What about Woolite?
I'd appreciate any suggestions. Thank you!
