I'm certain I asked the same question years ago, (sorry) ..but that was for venting around the WBS.

In need of a internal diam 100 x100 mm exterior vent that is vermin proof, so metal with mesh behind it.

The old one for the then tumble drier has suffered brittleness & has been chewed by vermin (5 mice alerted me to this in our conservatory after harvest).

Actual vent isn't needed since we got the new ASHP tumble drier but does provide some cooling / cold that balances out seasonally.

Haven't seen any metal blocking plates, nor sturdy meshed metal covers (that are vermin proof), but these must exist.

Anyone point me in the right direction?  checked screwfix, nothing. ironmongers direct, plenty of metal that looks like a mouse could compress its skeleton between.

B&Q, MachineMart, even local iron mongers (or the modern equivalent), car body repair shop for the mesh.  Even beekeeping suppliers.  But if you want a made to measure, ‘just-stick/screw-to-the-wall jobbie’ I can’t help.

I had to stop the birds nesting in the workshop extractor vent that had curled up like a BR cheese sandwich.
Drink beer first. Then tin-snips, pliers, bicycle spokes for pivot spindles, 1/2 hour of faffing, and hey presto, job done:

Thanks, things have got better since I last looked...

Found this at toolstation (sadly though you CAN poke a bic biro through it, but it's S/steel & tougher than plastic so can be modified.

https://www.toolstation.com/stainless-steel-bull-nose-vent-grill/p49037?bvstate=pg:2/ct:r  ..cheap

& have just ordered this (they sell it in multiple sizes for not much more, ..shipped from china) ..bah! the mesh looks smaller diameter gaps...we will see £8.49 -thru £10.49 for a 20 cm diameter).
will plug the hole & fit it in the autumnal rain!

Just as an update (for anyone trawling solutions years down the line).

After catching a plethora of mice I'm rethinking areas I couldn't previously access & stuffing them with a packing layer of screwfix wire wool . followed up by mesh (I am opting for high purity copper as the outer layer, ..my reason for this is that its better to lose some cheap material at the top of a hole cut in plasterboard by the original builders to put the sewage down pipe & vent through which is a access run for any vermin than the expensive stuff (copper) I hope to float on top.

At the bottom in the kitchen (nigh on unnacessible) the plasterboard was cut short leaving access at the bottom, again stuffing with a technical tool known as "a stick" then overlain by the copper mesh to make an impregnable seal at the bottom.

Found this Warrington based firm to be cheaper than they are selling on big river & flea-bay!  https://www.themeshcompany.com ..many mesh varieties for your pleasure!.

Is it recommended to coat the wire wool in WD40 or similar to add a protective layer do you think? ..& ditto the s/steel vent when it arrives?
