HELP! A mouse electrocuted me

[OctogenarianDecathlete]

Well, technically the dishwasher electrocuted me but only because a mouse has chewed through the cable.

I need all tips on how to get rid of it.

Not just any mouse, we have an Ultra Mouse.

We have a young cat. He went through a phase of bringing live mice in.

We bought humane traps and caught and released several.

Except one.

This 🤬 mouse will not be caught or killed. We've tried all kinds of traps, bait and poison.

We're in a 14 year old shoddily built house with holes in the walls that allow the mouse to move between kitchen, bathroom and garage. It's been getting into the kitchen cupboards from behind. It abseils down onto the worktop (we sprinkle bicarbonate and have footprints in the mornings).

We were trying to use humane traps initially but the 🤬 has had enough chances and needs to just go.

Please give me all your tips on traps, bait and poisons.

I'm this close to burning the house down (or at least, the mouse might manage it itself).

Thank you @Crazymadchickenlady .

Whilst it doesn't have a personal vendetta it has caused her to be electrocuted. That can actually kill you.
Should she just cross her fingers that other methods work?
Hope the next bout of chewing doesn't cause a fire?
Hope the next electrocuted doesn't stop her heart, or the heart of a family member?

If a family member dies or her house burns down, she can reassure herself that at least a little mouse didn't suffer eh?

I mean, so long as the fluffy mouse isn't suffering everything else is acceptable 🙄
