Cotton Pickin' Whiteflies! I Surrender!

By Oppositeofnormal @oppositeonormal
So, I recently rekindled my love of gardening and was quickly reminded of one of the main frustrations that go along with it. Pests. Namely, whiteflies. Ugh!
More detailed information on whiteflies.
How does one tell when they have a whitefly infestation. Easily. If you see a small white cloud appear when you are watering or touch a plant, you have them.
I have read numerous articles on how to get rid of these little buggers without pesticides. Many sites have suggested the following methods:
  • Diluted Dawn (the blue one, and it must be the Dawn brand!) in a spray bottle, sprayed on the plant, especially under the leaves, once a day. 
  • Vacuuming them! Yep, you heard me. Get out your Dustbuster and go to town. 
  • Earthworm casings on top of the soil.
  • Garlic crushed and placed on the top soil.
  • Milk, diluted. Supposedly they don't like the taste that it gives the plant.
I have tried every single one of these to no avail. 
I am beginning to realize that it may just be a regional problem. I was at Lowe's geeking out in their garden center, and was lucky enough to run across a Bonnie representative restocking the vegetables and she informed me that where there is cotton, there are whiteflies. Well, considering the vast amount of cotton that is grown within a 25 mile radius of my house, and that my neighborhood sits squarely in between 3 cotton fields about a mile long each, it's safe to say I am screwed. And you know what? My plants are fine.
Whiteflies, you win.
