My wife trapped the mouse in the bathroom. Well, we think it’s trapped at least. After a quick Google search, it seems that they can squeeze through spots as thin as 6mm. The gap under our door is definitely smaller than that, so small we can’t squeeze a towel under the door. So, we hope it’s trapped.
I guess we’ll call Rid-a-Critter or someone similar in the morning. I know traps alone won’t fix the problem. We’ll have to find some holes and fill them. The problem is - how can you find every hole that’s 6mm or more? That’ll be impossible.
