How to close this gap

[Father Ted]

This gap seems to be letting mice into the cupboard.

What is thy best way to seal it and prevent them from getting back in again?

Quickest way is expanding foam. Rub some vaseline on the pipe so the foam does not bond to it in case you need to remove it in the future. Trim the expanded foam flush with the wall to get an even face.

Will the mice eat through the foam?

You could stuff the hole with wire mesh first and then spray EF in the hole. Or break up a tile and mix the pieces with cement as a filler.

pebbles stones metal mesh even screws or nails wedged in the space surrounded by foam/no nails even silicon to hold the padding secure so a nibble will leave 90% off support in place but keep your eye on the pipe as this may turn to there point off focus as the softest where a normal bit off tin can be introduced in the area as a cuff or sheild to detract attention

Yes, they will. Cement is a better idea. But if you must use foam, put some steel wool (or a brillo pad) in as well.

BA makes a good point about the plastic pipe maybe being vulnerable. I think the mice got in because it was easy; they will only make an effort if they find a food source. You could also add some rodent killer granules into the mix as belt and braces.

I use soft packing foam (like the stuff in sofa seats etc) around pipes usually as it's less messy then expanding foam, cheap (free often) and can easily be removed. If it's just to stop draughts etc it works very well. If Mice are an issue then as others have said pack some wire mesh, steel wool or similar in there first then add the foam.

Would this stuff be a better option?

No. Sledgehammer and nut comes to mind.Either mix a bit of sand and cement or do as Rorschach says.

[Father Ted]

I've got sand and cement. No foam. Would I need unibond or anything to prep the wall for the cement?

[dewaltdisney]

Wet the hole well, and put wire wool in the mix. The wetting stops the wall sucking the water out of the mix too quickly.
