Rodents entry via air brick and how to block?

damouse · 16 Nov 2019

Hi all

Heard some scratching under the floorboards last night and I fear we may have unwelcome guests. Hoping it's mice but you never know it could be those 'other' guys

I've had a quick look outside the house this morning and noticed that a few of our plastic vents seem to have holes in that I don't recall seeing before. They don't look chewed by an animal - more like a clean break and I can't see any broken plastic bits around on the ground.

What do you think? likely point of entry right? ...

What are the best ways to block entry but allow airflow? I have 5 similar vents to deal with.

Fine wire mesh?

Cheers guys ... I image that meshing would need to sit on the outside though somehow. Might not look so great.

I saw some specific rodent proof vents on Amazon - 16 quid a pop seems steep though for a frame and a mesh in the shape of an air brick.

Thinking this might be an alternative - see attached image and could even spray it dark grey to blend in with the existing brick work.

What do you think?

You could spray the mesh.

If really OCD, break out the airbricks, mesh new ones at the rear and refit?

Cancel that, I've learned to read!

I like it , would keep things looking neat

Mice can get through holes the size of a pencil it's difficult to keep them out ,we have a problem with them at work every year when it starts getting colder

If you haven't got a trap door to under your suspended you could drill a hole in your floor and use an inspection camera to take a peek or stick the camera through the vent to confirm

Failing that chat someone up with a thermal imaging camera!

Get on ebay. Loads of metalwork companies sell off the offcuts of perforated stainless steel mesh etc for a few quid. Cut to size or maybe lucky enough to get actual size.

Use these thru the mesh and vent to hold in place.
