I use warm water. The bubbles will splash all over your plant. And I find that the water gets freezing from the dry ice if you don't use warmer water.
The easiest way is to just ensure the splashing and container don't touch the plants.
But sometimes that isn't possible.

I've successfully used it on mealies, spider mites, scale, fungus gnats, and very bad aphid infestations.
