Well, what I used to have on the house plants were not aphids nor white flies, but very tiny brown flies which apparently liked to nest in the soil. Have had 100% success with adding a squirt of liquid soap to each gallon container of water which I always prepare ahead of need and allow to stand so it will be room temperature. This must make the soil unappealing for nesting. Penny, NY ___________________________________________________________________ Get the Internet just the way you want it.
