hey herbs

They're back! After a two year hiatus... they're back. I am already so happy to have plants on my balcony again. If I had known they would bring me such joy, I would have the-planted them two years ago when I pulled them up. I had a case of the white flies and they were terrible.
Any advice on an organic (or non-toxic...or not as toxic) way of getting rid of white flies?

Went to the nursery to get plants and potting soil, ran errands, edited a ton of photos... It was a great Friday.
