This method WORKS if done properly ...
Warm the thawed mouse /rat with a hairdryer until warm and dangle in front of their face using tongs - keep repeating the warming and offering process until it's taken , may take 6 or 7 attempts initially .
A couple of mine will only strike feed from within their hides so I do as dangle the rodent in front of the hide's entrance - usually works but if it fails simply reheat the rodent with a hairdryer and immediately offer again whilst it's still warm , continue until it's grabbed ...
I always wait until evenings to feed as they're nocturnal of course .

Incidentally , if it shows no interest at all not even a tongue flicker maybe it's best to leave for a week .
