Had the same thing happen with a squirrel a couple years back—little guy chewed right through the vent screen. I get what you mean about those baffles, though. They look flimsy but somehow they do the job. Did you notice any difference in your energy bills after clearing out the nest? I’m still not convinced mine are working as well as they should, but at least the attic doesn’t feel like a sauna anymore. Ever try those rigid foam baffles, or just stick with the cheap ones?
I’ve only used the cheap baffles so far, mostly because I can’t justify the extra cost for rigid foam until I see a real difference. My energy bills dropped a bit after clearing out the mess, but honestly, not as much as I hoped. Still, at least the attic isn’t baking anymore. I always wonder if the pricier baffles are really worth it or just marketing.

Honestly, I’ve seen both sides. The cheap baffles do the job for basic airflow, but when I started seeing mold spots in a couple attics—despite “enough” ventilation—it was almost always where the thin baffles sagged or got blocked by insulation. Rigid foam types hold their shape and don’t crush as easily, especially if you’ve got blown-in insulation. It’s not just marketing, but yeah, the price stings up front. If you’re planning to stay put a while, I’d lean toward the upgrade. Otherwise, just keep an eye out for moisture issues.
I get what you’re saying about the rigid foam baffles, but honestly, I’ve had the cheap cardboard ones in my attic for almost 10 years now and haven’t seen any mold or moisture problems. Maybe it depends on how careful you are with the install? I just made sure they were tucked in tight and checked them after blowing in more insulation. Not saying the pricier ones are a scam, but if you’re on a budget and willing to do a little extra work, the basic ones can hold up fine.
That’s actually pretty reassuring to hear about the cardboard baffles holding up that long. I always assumed they’d get soggy or start to sag after a few years, but maybe it really does come down to how careful you are with the install and keeping an eye on things. I’ve mostly used the foam ones because I was worried about moisture (our winters get pretty gnarly with ice dams), but I guess if you’ve got good airflow and you’re not seeing any mold, that’s what matters.
Curious—do you have ridge vents or just soffit vents up there? I’ve been thinking about swapping out my old box vents for a continuous ridge vent, but I’m not sure if it’ll make a huge difference or just be a hassle. My attic’s not huge, so maybe it’s overkill. Anyone else notice a big change after upgrading their ventilation setup?
