I found this post searching for solutions to the same problem. Because it is sort of a Sunday night emergency I took the advice of joedirt420 above and spritzed my plants with a solution of Pine Sol and water. I used 3/4 of an oz in a gallon of water.
It seemed okay. I don't think it will kill the plants, but I do think there is some question if it will kill all of the horrible freaking creatures. I'm going to repeat daily (probably) for a week or so.
I did all of the leaf bottoms and stems, most of the tops. I also spritzed the top layer of the dirt, and the buckets and water trays, and the floor and a good deal of the walls.
I had a friend that used a sulpher burner when he had the problem. No discussion. He did the burn, twice I think, each time he had the problem, and it seemed to work.
Here is what I found online regarding the sulpher burn device:
