We've used poison forever (well 25 years or so...) and only once ever had a dead mouse in the house. There have no doubt been a few up in the roof, but you only walk past the spot going: What's that smell? for a few days....
Far, far worse was the cat that decided to cark it in our front garden once. It was hidden between bushy clumps of kangaroo paw and I couldn't work out where the stench was coming from until I finally found its rotting remains.
Traps are a no-no for me. I'd have a panic attack if I had to deal with dead bodies. Or live ones. Give me a house full of crickets and spiders any day, thanks.
