I’ll add a few more considerations to this discussion.

Gaps beneath the doors should be minimized. Door sweeps are a good option, but 
only if the floor or threshold beneath the door is level. The Xcluder sweeps, 
if sized just right and installed properly, are quite effective, and should be 
expected to outlive many of the cheaper plain vinyl or rubber sweeps. Drop-down 
bayonet kinds of sweeps (such as those manufactured by Pemko) can similarly be 
effective, but one should be cautious to minimize the amount of the rubber 
strip showing at the bottom, lest mice will nibble through it in short order. 
Another option to reduce the gap is to install a new wood or metal threshold 
beneath the door. This is particularly appropriate where the floor has become 
worn from decades of foot traffic.

The astragal gap between double doors should be minimized as well. This may be 
accomplished by installing shims behind the hinges or by retrofitting the doors 
with an astragal closure, such as that made by Xcluder.

The various kinds of brush sweeps can afford some amount of protection against 
insect and rodents, but a determined mouse or rat can often push through the 
bristles.

Gaps in door frames and other sites can and should certainly be sealed. Plain 
steel wool is probably not a good option, as it will soon oxidize and 
deteriorate. Stainless steel or copper wool / mesh would be far better choices. 
I’d advise staying away from filling gaps with expanding foam, unless the voids 
are first filled with something far more substantial.

Thanks all for the responses, some very useful tips which I’ll cost up now. 
Please see below a little summary of the suggestions:


·         Metal-coat the threshold and the outer bottom lip of the door to 
prevent gnawing (e.g., aluminium/brass threshold cover plates).

·         Fit brush style door sweeps, e.g. Xcluder pest control door sweep

·         Fill any gaps/holes with steel/brass wool.

Actually brass wool works better- doesn't rust.  It's available from suppliers 
like Grainger and McMaster-Carr in cases.

Use steel wool.  Fill in the suspected gaps with the wool.  We have been using 
for all our doors and other gaps and holes in the wall.  It does work.

Dear colleagues,

We have a low level problem with mouse ingress through four doors on one side 
of the building and I am wondering whether you may have any experience with 
retrospective mouse proofing of external doors.

The doors in question are solid wood with wooden thresholds; there is a gap 
under all of the doors which is not big but I suspect just large enough for the 
mice to squeeze through. They are closed most of the time but lead to our 
lecture theatre and when they are open are frequented by hundreds of feet. I am 
therefore looking for a solution that is secure and sturdy at the same time. 
And cost-efficient, of course.

Gratefully yours
Christian
