wrote in UO6Mh.14001$el3.5242@trndny01: FWIW, I find that so-called "insecticidal soaps" offer no advantage over ordinary household liquid dishwashing detergents, and the same might be said for horticultural oils compared to vegetable cooking oils. My preferred spray for spot treatments is a tablespoon each of cooking oil and liquid dishwashing soap (I use a brand made from 100% vegetable and fruit oils) in a quart of water. Would the addition of 50% alcohol to that mixture be expected to increase its effectiveness? |
