Yes, blow-drying helps prescent the room. Of course, I have BPs now that are up front and watching within seconds of me turning it on, even without a rat in the room!
I know some people don't like the smell of blow-dried rodent, but I never thaw mine in water. I can't stand the thought/sight of rat soup! Not to mention keeping water hot enough to thaw/warm 30 rats at a time.
