Hey Jason! I had a problem last summer with whiteflies attacking all the plants in my sunroom. They were particularly fond of my plumeria and my tropical impatiens. I ended up using one of their favorite impatiens as "bait"-- I treated it with systemic bug killer, which didn't hurt the plant but killed the little buggers. Worked very effectively. Eventually all the whiteflies made their way to the "bait" plant and the infestation went away. (I had already tried spraying a soap mixture, doing natural alternatives, etc. The systemic thing did the trick).

I was doing some research and I found that nasturtiums are supposed to be irresistible to the little buggers. So this year, I'm putting nasturtiums in my sunroom and treating them with the systemic bug killer. I'm betting that the nasturtiums will be easier for the bugs to munch than the thicker tropical plants, and by treating them with the systemic killer, it will get rid of the problem.

I wish I had tried this last year so I could tell you how it worked, but, like I said, I had great success with treating one of my impatiens. The whiteflies didn't last long after that. Hopefully I'll be ahead of the game this year and they'll go after the nasturtiums and not bother my impatiens either! Nasturtiums as a "living fly strip?" I guess we'll see!

Good luck!
