We have had better success with the brush type door sweeps. Rodents seem to not
chew on these types as opposed to the rubber/latex ones and they hold up to the
elements way longer. It is believed that they do not like to chew the brush
ones because it has something to do with irritating their teeth or mouths. JTV

We anticipate installing sweeps in the very near future and these have been
recommended. I’d be interested if anyone has insights or experience with them.

We have interior doors that appear to be hollow and filled with Styrofoam
beadboard. For a time we had mice getting into these and shredding the
Styrofoam, presumably to make nests. I’m glad to say that since we managed to
exclude mice from the building, this problem has gone away. No-pne wanted to
dismount the (large) doors to put metal plates on the bottom…..
Best,

Dan,
For hollow doors that are on the interior of a building that is under
temperature control, then there would seem little value to weep holes. In those
cases, the holes can be blocked. A small square of aluminum flashing, held in
place with an appropriate adhesive (I like silicone) works wonders. If you’re
able to get your fingers under the door easily, then the repair is simple.
Sometimes, the doors need to be removed from their hinges. That’s best left to
locksmiths or other door repair folks.
If the door is in an area that suffers from temperature and humidity
fluctuations (as with an exterior door), then consider a metal mesh. I’d select
something that is not oxidizing. Stainless steel hardware cloth works well.
Xcluder fabric will breath and allow water to pass, but it would be difficult
to secure it in place.
I recommend that all doors be inspected and modified prior to installation. It
is far more costly and difficult to mitigate after the doors have become mouse
condos.
In any case, be sure that any modifications do not compromise the fire rating
of the door. If in doubt, ask someone skilled in that arena.

Richard,
Thanks! In cases where they are weep holes, would you recommend the metal mesh
to allow moisture to escape? I’m wondering if there are issues of weep holes
are completely sealed.

Dan,
Those holes are sometimes weep holes, but other times they’re formed into the
door bottom to help with handling during manufacturing. Mice readily find these
portals to an attractive and comfortable abode.
I posted some images and suggestions here:

Regarding Jef’s comment below, I believe the structural holes in the bottom of
metal doors are weep holes, put there to allow moisture to escape. I can see
where they could provide harborage for pests, but I wonder if it would be
better to screen them than to cover them; a question to ask the door
manufacturer, I think.

Subject: Re: [PestList] Door Sweep Recommendations
I find single-blade doorsweeps almost useless, but that's mainly because my
museum is actually a zoo, and mice are a constant gnawing presence. Xcluder
sweeps are the best single blade doorsweeps against mice, which quickly chew
through vinyl or bristles in a very short time. I had another problem, which is
hollow metal doors with structural holes on the bottom surface (where you can't
see) which mice and insects love to use as harborage. I ended up switching to
the first style of doorsweep you showed (an inexpensive similar product made by
Frost King) to cover these holes.

Greetings PestList,
The Museum at FIT is looking to upgrade our door sweeps and would greatly
appreciate any input or recommendations.
We currently have this style:
[cid:[email protected]]
However, due to the frequently uneven floors, gaps are apparent beneath the
sweep.
We're looking at this style:
[cid:[email protected]]
We hope that the face-mount style will provide flexibility for uneven floors
that the under-mount style did not.
Does anyone have preferred brands or words-of-wisdom for the replacement
process? Any input is greatly appreciated.
Thanks in advance,
