Mouse problem

[eltax91]

Hi guys

In need of some help. We have a single story extension to our lounge at home. Built in the 70's with a flat roof.

I'm not sure how, but a mouse has got, or is getting in to the space between the plasterboard and the roof.

I had the council pest control out and they looked all around and could not identify an entry point. The only suggestion was its coming through the cavity wall. He suggested cutting a hole in the ceiling and putting poison in, attached to some steel twine and tape it to the ceiling. Which I did.

I thought this had been sorted, 2 big blocks of poison were nibbled away and we heard nothing for a few weeks. Now it's back with a vengeance. It won't take poison from location 1, so now I have a second hole in the roof.

It seems it's not taking poison from here either. Although I can hear it scratching right next to the damn poison!

This is driving my pregnant wife mental, she's emotional at best at the moment but just looks at the tape covering the hole and sees disease, rational or not she is getting sick of it.

So, any other solutions? Am I going to have to rip the ceiling down? If so, then so be it, but I'd rather not. The only other thought is some kind of gas! Can't get a trap up there due to the insulation and it's either a super mouse immune to poison, or knows what I'm trying to feed it!!

HELP!

You will have to find the hole that they use to enter the building and block it with expanding foam and steel wool, block every hole bigger than a 5p piece.

Even though it will be a complete pain, it is the only option to permanently stop it because the mice will all use the same rat run to enter the building and as they walk they constantly pee so it forms an invisible path for any other mice to follow so killing just one or two wont do much.

I'd rip it down and find out how they are getting in and solve that.

Dead mice in inaccessible places will smell and cause a plague of flies, and nature has an inexhaustible supply of new mice waiting to move in anyway.

As above, you need to work out where they're getting in as many more will follow the same path.

Little sts they are, already killed 5 in the last month as our house is like a sieve when it comes to mice. Slowly blocking up the entry points though.

Look for the usb port.

Try one of those ultrasonic rodent repellents?

You better hope its not one of the so called 'mighty mice' those wee brutes look solid.

Any existing holes are best filled with steel wool.

Amazon sell some good rat and mouse poison, comes in pink stuff that looks like putty, spread it on a biscuit.

Make sure there is no food source that they want in the house, thats why they are coming in.

Do the neighbours have fat balls out for the birds, ask them to stop.

Mice are good climbers, have seen them climb sheer walls, and go down head first

Borrow a cat.

When we were students we borrowed cats for an evening

My grandad who was a farmer always had good results with baking trays joined to the mains somehow

He'd put food in the middle of the tray and they die trying to get it

Obviously this might not be good in a domestic situ

We had a similar problem — mice going up through the cavity to the loft.

When we had the patio take up a couple of years ago, we discovered that when an extension was built, the builder had used a concrete lintel to bridge the gap between the original house & the extension. the mice were gaining entry down a hole by the side of a rainwater downpipe & then up into the cavity. Since we blocked that up, we've had no more nighttime rustlings — fingers crossed that's sorted the problem permanently.
