Ah, but we were talking earlier about dishwashing liquid sprays so I thought you might have meant that, Sabrina. I believe some people use baby shampoo in home-made remedies for plants also. I'm not generally a fan of using something not formulated specifically for plants because there is more risk of plant damage and also I suspect collecting together all the ingredients may work out more costly than just buying something like commercial insecticidal soap (which is also organic, where that's a concern, whereas concoctions made from household ingredients generally are not).
