Something you could do to help with the temp change is put it all inside of a plastic bag, shake off the dirt, bring it back inside. Put another plastic bag over the leaves (and warm air) and go back out and use warm water in a bucket to give the roots a quick rinse then RUN back inside before you freeze your tuchas off!
But me, I'd wait for spring, lol.
And actually, if the plant looks good, why worry? Those bugs won't leave a nice, damp environment, I'd bet.
