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 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. --dan Dan Wixted Pesticide Management Education Program (PMEP) Cornell University Ph (607) 255-7525 525 Tower Road FAX (607) 255-3075 CALS Surge Facility psep.cce.cornell.edu<https://urldefense.proofpoint.com/v2/url?u=http-3A__psep.cce.cornell.edu_&d=DwMFaQ&c=WO-RGvefibhHBZq3fL85hQ&r=GO7C3XN3WgFy2IP-bFBbnUs_CYntqj57Dprtl40-_KE&m=r_OjRSq8Cll4O87BbKcYGnzCDp1vN29ukRxr9fTno0Q&s=ALcLscSSdNi717uKI4jAd2KNTPNh2kO75LSCX0MWM-Q&e=> Ithaca, NY 14853 dj...@cornell.edu<mailto:dj...@cornell.edu> From: pestlist@googlegroups.com <pestlist@googlegroups.com> On Behalf Of Jef Taylor Sent: Friday, January 29, 2021 12:34 PM To: pestlist@googlegroups.com 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.

We currently have this style: [cid:image001.jpg@01D6F647.B6146870] However, due to the frequently uneven floors, gaps are apparent beneath the sweep. We're looking at this style: [cid:image002.jpg@01D6F647.B6146870] 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.
