Copper mesh actually works better than most folks think, especially for those weird little gaps around pipes. I’ve stuffed it in spots where steel wool just rusted out, and it holds up. If you want to keep insulation from becoming mouse condos, I’ve had decent luck with closed-cell pipe wrap—less tasty for critters, doesn’t soak up moisture. It’s not perfect, but cuts down on the yearly scramble. Still gotta patch up new holes every fall though... seems like that’s just part of the routine.
Can’t argue with copper mesh—it’s been a lifesaver for me too, especially in old basements where things never quite line up. I’d just add: after stuffing gaps, I like to seal over with a bit of expanding foam or caulk, gives a double barrier. Closed-cell wrap is solid, but sometimes in really cold spots I’ll still see condensation—worth keeping an eye out for that. Mice seem to find new routes every year no matter what... part of the fun, right?
Copper mesh is great, but I’ve seen folks skip the foam and regret it later—mice are relentless, and they’ll squeeze through a gap you’d swear was too small. I’m with you on condensation too; closed-cell wrap helps, but in older homes, sometimes nothing’s perfect. Had a job last winter where the pipes still sweated, even with double wrap... just one of those things you keep chasing.
Yeah, mice are wild—never underestimate what they’ll squeeze through. I’ve seen them get past copper mesh if there’s even the tiniest gap, so I always double up with foam too. About that condensation, though… have you ever tried using those pipe heating cables? I’ve heard mixed things, but I’m curious if they actually help with sweating pipes or just prevent freezing. Seems like in older basements, you’re always fighting moisture no matter what you do.
I’ve tried heat cables a couple times, and honestly, they’re really just for freeze protection. They don’t do much for condensation or “sweating” pipes. For that, you’re better off with proper pipe insulation—get the thick foam sleeves and make sure all the joints are sealed up tight. In older basements, humidity’s always a battle... sometimes a good dehumidifier is the only thing that keeps it under control. Mice, on the other hand, seem to see any gap as an invitation—totally agree there.
