Have you tried sealing the edges with silicone after packing the mesh? I’m curious if that would help with critters squeezing through gaps as things settle.
Funny you mention silicone—I actually tried it once, thinking I was a genius. It *did* help keep the mesh in place, but I underestimated how much dust and gunk collects behind the fridge. The silicone turned into a magnet for every stray crumb and fuzz bunny in the county. Not a dealbreaker, but it looked pretty gross when I had to move things for a repair.
As for critters, I think it depends on what you’re dealing with. Mice are like tiny Houdinis... if there’s even a sliver of space, they’ll find it. The combo of mesh + adhesive or silicone is better than mesh alone, though. I’ve also heard some folks swear by using steel wool instead of copper mesh, but that stuff rusts if there’s any moisture.
Anyone else had luck with something less messy than silicone? Or maybe I just need to clean behind my fridge more often...
That’s actually kind of reassuring to hear I’m not the only one who’s had silicone turn into a dust trap. I always wonder if I’m just being too picky, but it really does get gross fast, especially in those hidden spots. I’ve tried that expanding foam stuff once, but it looked even worse when I had to patch it later. You’re right about mice, too—they’ll squeeze through anything. Maybe a combo of mesh and something easy to clean is the sweet spot? Or maybe I just need to get over the mess behind appliances...
Plumbing Tips That Change With The Seasons
Dust and gunk behind appliances is just one of those things that’s always going to be a pain, especially with silicone. You’re not being too picky at all—silicone does seem to attract every bit of dust and pet hair in the house, especially if it’s not perfectly smoothed out. I’ve seen plenty of jobs where the caulk line just turns into a magnet for grime after a few months. It’s even worse if you use the wrong type and it never fully cures.
Expanding foam is a mixed bag, honestly. It does a great job sealing up gaps from a pest-control perspective, but patching it later or trying to make it look neat is a headache. I’ve had to chip out old foam that was chewed by mice (they’ll go right through it sometimes), and it left an even bigger mess.
Mesh plus something washable is actually a solid approach, especially in spots where you need airflow but want to keep critters out. Stainless steel mesh is my go-to for under-sink cabinets or behind stoves—just cut it to size and staple or screw it in place, then run a thin bead of paintable caulk (not silicone) around the edges. That way, you can wipe it down if it gets dusty, and if you ever need to pull it off, you’re not stuck scraping off stubborn residue.
If you’re dealing with seasonal changes—like pipes sweating in summer or drafts in winter—it helps to check those hidden spaces every couple months. Sometimes I’ll find that what worked in January is suddenly letting in ants or cold air by July. One trick: use removable weatherstripping or foam tape for gaps that might need cleaning or adjusting as the seasons shift. It’s not as permanent as caulk or foam, but way easier to swap out when things get gross.
Honestly, nobody likes pulling out appliances just to clean behind them, but keeping those areas accessible makes life easier long-term. If you can’t stand the mess, maybe try sliding trays or mats behind your fridge or stove—they catch the worst of the dust and crumbs and make cleanup less of a chore.
Anyway, don’t beat yourself up over being picky. Most people just ignore what they can’t see... but you’re probably saving yourself headaches down the line by staying on top of it.
Sliding trays behind appliances are a game changer—totally agree there. I used to dread the annual “move the fridge and see what horrors lurk beneath” routine, but now it’s just a quick slide-out, wipe, and done. For the silicone, I’ve honestly started using painter’s tape to get a crisp line, then smoothing it with a wet finger (or, let’s be real, a spoon handle when I’m feeling fancy). It still grabs dust, but at least it looks intentional.
One thing I’ve found with sweating pipes in the summer: pipe insulation sleeves are cheap and make a big difference. I just measure, cut, and pop them on—no glue, no drama. They’re easy to pull off if you need to check for leaks, too. In the winter, I stick those draft stoppers (the kind that look like a snake) along the bottom of doors near plumbing runs. Not pretty, but they help.
And yeah, expanding foam is a double-edged sword. I swear, once you use it, you’ll be finding little yellow crumbs for months. Mesh and caulk is way less drama in the long run.

Draft stoppers are underrated, honestly. I’ve tried the “foam pipe wrap plus heat tape” combo for exposed pipes in my crawlspace, but it’s a pain to monitor. Have you ever had issues with condensation inside the insulation sleeves during humid spells? That’s tripped me up before—sometimes it just traps moisture instead of stopping it.
