Vicky, I think the gnat-like bugs that fly up may be whiteflies. I don't know if you can get a photo of them or not, because they do tend to fly up at the least disturbance. That makes them difficult to control with insecticidal sprays. They are sucking insects, so products that leave a residue on the leaves won't control them, either. Contact insecticides, such as as soap solutions and neem oil sprays, work best if applied when the insects are in the nymphal stages. You may want to try those. At least they would limit the infestation and the damage to your plants.
I have no idea what the neon green thing might be, though. Could you post a photo of that for us? It would be very helpful. If you need instructions for posting images, just click on the link below.
