An Engineer in Wonderland – Building a more interesting mouse trap

There was a drawback to thoroughly removing the nasty old glass insulation from my loft and replacing it with nice safe polyester fluff.

Rodents have moved in.

It may just be a coincidence, but when I took out the mineral wool there were only a couple of birds nests in the loft and not a sign of a mouse.

Now I hear little feet scurrying around at night, and things are starting to get chewed.

I am normally of the live-and-let-live persuasion, but not when the interloper might eat the insulation off my cables and burn the house down.

So the critter or critters must go.

At this point I can hear voices shouting ‘poison the buggers’ and, believe me, I have contemplated the little boxes that cost only £5 and kill up to 50 mice.

But I squeamishly feel that my furry invaders should have at least some chance of survival.

So I have borrowed a ‘humane’ mouse trap and put it down this morning.

And await results.

In the mean time I asked Mr Google where I could buy some more, and he delivered several marvellous websites devoted to inventing humane mousetraps.

Why didn’t I think of inventing my own?

I blame lack of imagination, and ignorance of mouse dynamics.

Highlights amongst the mouse catching sites were:

This one which has several great ideas from a brain storming session, and the crew involved has even tested and timed two of them using pet mice.

Watching the videos caused a revelation, I had no idea mice were so inquisitive and would be caught so quickly. 

I was assuming a multi-day wait.

This one looks fairly tricky to set, but can be extended to rats if necessary.

– Hmmm, hope it isn’t rats in the loft.

And the one I like most so far, and may be trying tonight, needs only a toilet roll centre and some bait.

How elegant

  1. A very good point Paul. I remember going away for a long weekend and my flatmates, who had insisted on the “humane” traps in the first place, had neglected top check the traps. Unfortunately, for one mouse.

  2. A brief note from personal experience: The important thing about humane mousetraps is remembering where you put them. If the first time you remember them is when the (now deceased) mouse begins to smell a bit, you really can’t continue to call them “humane”…

  3. Thanks for that, I had no idea.
    For legal reasons therefor, I will not be describing the results of my attempt at rodent recycling!

  4. The Wildlife and Countryside Act 1981 says that it is illegal to release vermin into the wild, so once you have caught your mouse, you still have to kill it.
