I fogged some of my vivariums around the same time frame so I'll go over my results here also just to keep them all in the same place.
I have/had a few fruit fly like bugs, some garden worms (still don't know where they are coming from), and some small centipeds. The fogging killed most but not all of the centipeds, fruit fly's, but didn't really bother the worms. I had some spiders living in the hydroton also, they are all dead . They were eating the other bugs and never moved up into the rest of the tank. The perfect house guests until I killed them.
I too would say my plants experienced a very rapid growth spurt, and none of them seem to have any ill effects from the fogging. I'm currently working on a trial system to "play around" with adding CO2 into a vivarium due to the results from the dry ice experience, it was that dramitic.
I might see 1 bug for every 20 I used to see, I have not done a 2nd fogging yet.
