How to Get Rid of a Horde of Dead Mice

My human mouse traps didn't work, so I called the pest control people. And they identified a whole where they were coming in round the back of the house. They put down loads of poison, like little trays of poison in various different places around the flat. In the meantime, you will hear them for the next seven to 10 days - but they're going to slowly die because they'll keep on killing themselves by eating this bait. Then they'll just die and decompose under your floorboards.
