Today, I found a dead mouse in my kitchen (or galley, I suppose, it being a houseboat). This is way better than it sounds.
I've had mouse sounds keeping me awake at night for a week, and had to clear mouse droppings off the window sills. Didn't really want to kill them; it's not the mouse's fault it's a pest; so I bought a sonar repeller. I saw a mouse casually stroll past it as it was supposedly making sounds that mice can't tolerate. I bought a humane trap - caught two in one night, and deposited them within the suggested 100 yard perimeter where they won't die of starvation and exposure. But all the time there were mouse sounds keeping me awake.
So I thought fuck it, I hate doing it, but they'll breed and breed if I don't kill them. So I bought traps and was setting them when I spotted the abovementioned corpse. There was a foil pack of disprin nearby - I suspect it poisoned itself.
Now there are no mouse sounds. It seems there was only one, and it just came back when I got rid of it. And now it's dead, and my hands are clean. And I've learned something - sonar repellers aren't worth a shite, and there's no real humane way of using a humane trap.
