I grew tomatoes from seed and they looked green and beautiful indoors. As soon as I set them outside they became covered with white flies and black flies. It also looks as though slugs are chomping on them at night. I would like to control pests by organic means only, no spraying or chemicals. Any suggestions? I have put out beer for slugs in the past and that seemed to work well.

The beer traps for slugs works well, so why not set some up again. The whiteflies will be difficult to eradicate, but you might be able to control the population by making sticky yellow traps and placing them at foliage level among your plants. Take bright yellow cardboard or index cards and smear them with petroleum jelly. Place them close to your plants and the whiteflies will be attracted by the yellow color, and get stuck when they land on the surface. Replace the traps as necessary. You might also try directing a strong stream of water at the undersides and stems of your plants where whiteflies lay eggs, to dislodge the next generation.
