Lighting up the backyard fence: solar, wired, or something else?

Is there actually any wiring or fixture that stands up to squirrels long-term? Or is it just about accepting you’ll be out there patching things every spring?

Honestly, I’ve yet to find anything truly “squirrel-proof.” Even metal conduit isn’t a guarantee—they’ll gnaw at the entry points if they’re determined enough. I did try one of those solar setups with a separate panel mounted up on the shed roof, and it’s lasted longer than the fence-mounted ones, probably because it’s out of their usual path. Still, the lights themselves are kind of hit or miss after a couple wet seasons. At this point, I just factor in a little maintenance every spring... seems like part of the deal if you want backyard lights and live anywhere near trees.

I get what you mean about maintenance being part of the deal, but I’ve actually had pretty good luck running low-voltage landscape lighting inside PVC conduit, then caulking the ends tight.

That’s actually a clever workaround with the PVC and caulk. I’ve always been a bit skeptical about how much protection conduit really offers—especially after watching a squirrel gnaw straight through a supposedly “rodent-proof” cable on my porch last year. Maybe it’s just the luck of the draw, or maybe the tight seal really does make a difference. I wonder if the type of PVC matters? Some of the older stuff around my place seems softer, and I wouldn’t put it past the local critters to give it a try if they got bored.

I do think there’s something to be said for making things as unappealing as possible for them. I’ve tried wrapping entry points with metal mesh, but honestly, it’s a pain to install and doesn’t look great on a historic fence. The caulked PVC sounds a lot less intrusive. Still, I can’t help but worry that once one squirrel figures it out, word gets around... They’re smarter than we give them credit for.

I hear you on the squirrel gossip network—they're like little furry engineers with a grudge. I once watched one drag half a bagel up my downspout just to stash it in my gutter, so I have zero faith in “rodent-proof” anything. The older PVC does seem softer, and I swear the critters around here can sniff out the weak spots. I tried painting some conduit with that pepper spray stuff as a test... not sure if it worked or if they just didn’t feel like chewing that day.

- Squirrels are basically the reason I stopped trusting “animal-proof” anything. I swear, if there’s a way in, they’ll find it (and then tell their buddies).
- For backyard fence lighting, I’ve been leaning toward solar mainly because it means fewer wires for the critters to chew on. The tradeoff is you have to deal with inconsistent brightness, especially if your yard gets a lot of shade.
- Wired lights are reliable, but the whole “rodent buffet” thing is real. Even with conduit, I’ve seen teeth marks. I tried running wiring inside metal conduit and wrapping it with reflective tape—looked weird, but seemed to slow them down.
- I’ve heard mixed things about the pepper spray trick. Sometimes I think the squirrels just see it as a challenge.
- If you’re feeling creative, low-voltage LED tape inside clear PVC (with the ends sealed) can work, but again, nothing’s 100% squirrel-proof.
- Honestly, I’m starting to think motion-activated lights with solar backup are the sweet spot—less tempting for squirrels, and you’re not wasting power.

It’s kind of a game of wits at this point... I’m not sure who’s winning.
