sticky cardboard, frenzied screams

I've become the resident rat-catcher. It's not something I'm particularly proud of but it is necessary. My chosen method of murdering these creatures is: sticky glue + several squares of cardboard left overnight on the kitchen floor.

The instructions on the sticky glue tell me:

The sticking of rats takes only a short while, the caught rat will give a frenzy scream, drawing other curious rats into the trap.

Once caught, the rats hair, which is sticking on the sticking plank should be burned....

I'm sure burning is hygienic but I can't bring myself to cremate the living, wriggling things. So I put another piece of cardboard on top of them, hold my breath and smack them with a hammer. Enough said. It's all gross.
