How to cover wall air vents with mouse mesh or air brick covers
There are instances when proofing a building from the outdoors will prevent a direct route of ingress for mice, and mouse meshing an air brick or fitting an air brick cover can stop mice from easily accessing your building from the garden.
Air brick mesh can be cut to size and attached to the outside of the air vent with fittings or sealant. In effect, preventing more mice from coming in will make the mice treatment more efficient. Nevertheless, mice can also travel freely from home to home by following the pipework running below the floors and within the walls.
How to get rid of mice for the long term
Therefore, carrying out the full mouse proofing of a property at living space level will protect your home from mice. As well, proofing the air vent will protect the building from being infested and the mouse proofing from being damaged at void space level. Hence, you will prevent mice activity and noise underneath the floorboards and within the walls.
Is your air brick vent used by mice to come into your property?
House mice originally come from the outdoors. They look for means to enter buildings by following the outer perimeter. In my experience, they may come in through gaps at masonry level, or take advantage of a gap below a door. But one of the most common ways of ingress is through an air brick vent.
Mouse mesh with air brick covers
Air brick vent covers normally get glued over the brick work and are perfect for modern buildings. However, air vent covers may not fit some older types of air brick vents very well. It’s also difficult to mouse mesh air bricks with a cover when the air vent is actually a grill. To mouse mesh grills, a bespoke solution is required.
Where can I buy mouse mesh?
When I first mouse proofed air bricks, I used supplies and materials from high street hardware shops. There were a number of fancy products that could be reconditioned as mouse proof air brick covers, but the downside was that they were not necessarily designed to withstand the weather.
Fast forward 15 years, and we now have galvanised mesh from a wholesale supplier. But the quantity of required mouse mesh plus the delivery charge makes this option not viable to the wider public.
How small does the air brick mesh need to be to stop mice?
Mice can squeeze in through very small gaps, but holes less than 0.5 cm are generally small enough to keep them out. The air brick mesh can have a finer section, but that often means that the wire diameter is thinner and more likely break. At Inoculand we use 0.5 cm section weaved mesh to mouse mesh air brick vents.
How to cover air brick vents with mouse mesh
The easiest way to attach mesh to air bricks is to drill holes in the surrounding bricks and use plugs, screws and washers to keep it tight. Covering air bricks with mouse mesh requires the use of a hammer drill. Alternatively, it is sometimes possible to jam the mesh in place in order to mouse mesh grills.
Our technicians are fully equipped with tools and materials. When it comes to the mouse mesh, they have large pieces that they can cut to size in order to fully cover the air brick vent.
