Here at ApcUK Services we have produced a short rodent control checklist and proofing guide to help keep rodents out of north London properties.
When looking for rodent entry points make sure you:
Airbricks and grates can break and make easy entry points
Gaps at the bottom of a garage door also offer easy access
Holes left by redundant pipe work
Gaps around pipe work
Missing vent pipe covers
Rotten soffit or facia
Missing roof or ridge tiles
Mortar missing from the verge
Rodent proofing guide
When proofing for mice, any hole or gap larger than 6mm needs to be proofed, so whether excluding rats, mice or squirrels, we would recommend filling all holes lager than 6mm to prevent future infestations.
The method that works on most building materials would be to use expanding foam and wire wool for holes up to 50mm. For holes over 50mm wire mesh can be used to temporarily exclude rodents from the building. However, longer term a more permanent repair should be sourced.
Of course we can’t cover every area of proofing and possible entry points in our short guide but we’d be more than happy to talk to you. Just contact us if you’d like any further information.
