We have a mouse infestation. There are droppings. I put a humane mouse trap near the droppings and caught about 10 mice and released them a long way away. Fine. Then the mice learned how to get out of the humane mouse trap. I don't know whether they chatted with each other about how to do this. I caught one of them in the trap, repeatedly hurling itself at the entrance side until it almost managed to get it to open enough for the mouse to slip through. I got that mouse, but others have taken the bait and forced their way out of the trap. So I got two of the killing traps and put them down. This morning the bait had gone from both traps. One trap was open and the other had sprung, but the mouse got away.
Should I move on to poison now? Won't that lead to horrible scenes of dead and dying and decomposing mice all over the house, including under the floorboards and in the ceilings?
