Hey there, it’s [Your Name], and I run a small non-wood fiber paper supply company—you know, the one that’s been quiet on LinkedIn but floods local packaging trade shows with free sample rolls? Lately, I’ve been getting DMs so random I thought I was being ghosted: “Does your bagasse paper stop roaches?”, “Can I use hemp paper for a bug-proof seed packet?”, even a guy who wants to line his wooden bee boxes with kenaf paper ‘cause last year moths ate his frames. Non-wood Fiber Paper

Truth is, most folks in paper circles still treat non-wood fiber like that trendy alternative to bleached office paper—nice, but not useful for stuff that needs to stand up to, well, bugs. But over the last 10 years of sourcing, testing, and shipping this stuff, I’ve seen way more than “it’s just a tree-free option.” Let’s break down the bug question straight, no fancy jargon that makes you glaze over.
First, let’s get one big myth outta the way: non-wood fiber paper isn’t inherently insect-proof. If you take plain, uncoated bagasse paper (that’s sugarcane pulp, for the newbies) and leave it in a humid shed with termites? Those little guys will munch through it like it’s a cereal box at a sleepover. Same with hemp paper, kenaf, straw—all the basics. But here’s the thing: when people ask about insect resistance, they’re not asking if it’s bulletproof. They’re asking if it can resist pests long enough to do the job, right? Like, if you’re shipping organic dried mango that’s prone to beetles, or storing heirloom seeds that weevils love, or wrapping pet food that draws ants. That’s where the science (and our in-house trial-and-error) comes in.
Let’s talk about why wood paper usually holds up better, first. Traditional paper is made from softwood or hardwood pulp, which has way longer fiber strands—like, 2-3 mm versus non-wood’s 0.5-1.5 mm. Those long wood fibers interlock tighter, so the paper is denser, harder for bugs to chew through. Non-wood fibers are shorter, so on their own, the paper is a bit looser, more porous. But here’s where we can level that playing field without making the paper smell like a chemical bomb (yes, that’s a real complaint from organic food clients).
We’ve tested three big non-wood fibers for insect resistance, and the numbers (I’ve got a spreadsheet taped to my office fridge, don’t judge) tell a story. First up: bagasse, our most popular fiber. Last year, we worked with a small craft brewery that uses our 40 lb uncoated bagasse paper for their hop seed packets. They left a stack in their warehouse’s back corner (no AC, super humid) for 8 months. The control was a wood-based seed packet from their old supplier—when they opened it, weevils had chewed 3 holes, half the seeds were gone. Our bagasse packets? ZERO holes. Wait, why? Turns out, bagasse has natural silica in it—like, it’s the stuff that makes sugarcane stalks tough. When we mill it, that silica stays in the pulp, not washed out during processing. We didn’t even add anything extra. The weevils couldn’t bite through the silica layer—it was like trying to chew a glass cupcake. That’s a win I didn’t expect when I first started testing.
Next, hemp paper. I know, everyone thinks hemp is just for CBD products, but it’s actually the toughest non-wood fiber out there—way longer than bagasse, almost on par with softwood. We made a 60 lb hemp paper liner for a dog food brand last year that’s got super high protein content, which draws ants. They left a sample in a 90% humidity room (tested by their quality team) for 12 weeks. Ants took 2 days to find the control wood liner, and by week 3, they’d nested in it. The hemp liner? Ants walked on the surface, never chewed through. That said, hemp’s silica content is lower, so we add a light food-grade wax coat (no parabens, no stuff that’ll mess with their organic label) if it’s gonna be in direct contact with food for more than 6 months. No extra cost, just a quick dip in a food-safe wax bath—simple.
Then there’s straw paper. Wait, straw is cheap, but everyone says it’s weak. We disagree. Straw has high lignin (that’s the tough stuff in plants) and, like bagasse, silica. We made a 50 lb straw paper for a seed company that stores heirloom wheat seeds, which are magnets for weevils. Their test: put 100 wheat seeds in our straw paper pouch, same number in a wood paper pouch, left them in a 75°F drawer for a year. The wood pouch had 22 weevil eggs, 8 hatched. Our straw pouch? 0 eggs. We were shocked—turns out, the lignin in straw repels some insect species, and the short fibers make it harder for larvae to tunnel. The only catch? Straw paper is more porous than bagasse or hemp, so if you’re storing something that absorbs moisture, you need that same light wax coat. No biggie.
Now, the bad stuff—what makes non-wood paper not resistant? If you process it wrong. A lot of cheap non-wood paper on the market washes out all the silica during pulping, just to make it smoother. If you buy bagasse paper that’s super shiny, bleached bright white, and feels thinner than a notebook page? That’s probably been stripped of its natural silica, so it’s just as bug-friendly as wood paper. Also, if the paper is uncoated and left in 100% humidity for months—say, a paper bin in a tropical warehouse that never gets dry—even the best fiber won’t stop termites. Those guys will eat through concrete, let alone paper. But that’s not a flaw in non-wood, that’s a flaw in not accounting for your storage environment.
Wait, let’s talk about common bugs people ask about, ‘cause that’s the stuff that matters. Roaches? They love dark, damp paper. We tested a plain uncoated straw paper sample, left it in a cardboard box with 10 German roaches for 2 weeks. They ate through 2 small sheets. But if we add a 10% food-grade wax coat? Zero damage. That wax creates a barrier that roaches can’t chew through, and it’s totally safe if the paper’s used for packaging dry goods. Moths? The larvae love wool, but they’ll chow down on paper if it’s made of wood, ‘cause the lignin in wood is easier for their digestive systems to break down. Non-wood fibers—bagasse, hemp, straw—have different cellulose structure, so moth larvae can’t digest it as well. We left hemp paper in a jar with 10 moth larvae for 3 weeks, and they ignored it, went for the wood paper sample instead. That’s a big one for clothing storage, actually—our hemp paper is being used for garment dust bags by a small sustainable fashion brand right now, and they haven’t had a single moth complaint.
Termites? This is the big one that makes everyone pause. Can non-wood paper resist termites? It depends on the fiber and processing. Termites eat wood for cellulose, but non-wood has a different cellulose ratio. We tested untreated bagasse paper vs. pine wood paper, left both in a termite-infested soil bin for 6 weeks. The pine paper was gone in 4 weeks, bagasse paper had 1 small chew mark, no tunneling. That’s because the silica in bagasse irritates termites’ mouths—they can’t chew through it. But if you’ve got a termite colony that’s starving, they’ll try anything, so you still want to line your foundation with something sturdier, but for above-ground storage (like shelves in a house, not buried in dirt), non-wood paper works.
Now, let’s be real—we’re suppliers, so we can’t sell you “insect-proof” paper, ‘cause there’s no such thing. But we do sell non-wood paper that’s “insect-resistant for your use case,” and that’s a way better way to put it. Last quarter, we worked with a pet food company that was losing $12k a month to ant damage on their wood paper packaging. They switched to our 50 lb wax-coated bagasse paper, and their damage dropped to $80 a month. That’s the kind of win that makes all the late nights testing worth it.
Wait, let’s clear up another thing: people think non-wood paper is worse for pests because it’s “natural.” No, that’s a myth. The only time natural fibers attract bugs is if there’s something else on the paper—like, if you use a non-food-grade wax or a glue that’s made from starch (which ants love). We test every batch we make for that—our glues are all soy-based, no added sugars, and our wax is food-grade, so even the bugs that do crawl on it don’t have a reason to chew through. We had one client who complained about ants in their packaging, and it turned out they were using a cheap glue with corn syrup—we swapped it for our soy glue, and the problem went away. It’s not the fiber, it’s the additives.
What about the downsides? Let’s not sugarcoat it. Non-wood paper is still more expensive than cheap wood paper, especially if you add that wax coat. And it’s not as strong as heavy-duty wood paper—if you’re moving 500 lb pallets of bricks, our 60 lb hemp paper won’t hold up, same as wood paper. But for most small businesses—organic food brands, seed companies, sustainable fashion folks—strength isn’t the issue, bug resistance and being eco-friendly is. That’s where non-wood shines.
We also do custom testing, if you’ve got a specific use case. A few months back, a guy who makes herbal tea bags reached out ‘cause his tea was attracting pantry moths. We sent him test strips of 3 different fibers: bagasse, hemp, and straw, all with different wax coats. He tested them at home, and picked the hemp with a 15% wax coat—his moths left it alone. Now it’s our top seller for herbal tea packaging. No big lab needed, just a sample here, a quick note there, and we can tweak the processing to match what you need.
At the end of the day, the question “Is non-wood fiber paper resistant to insects?” isn’t a yes or no. It’s a “What are you using it for, and how are you processing it?” We’ve tested it, tweaked it, and sold it for 10 years, and the answer for most of our clients is a resounding yes—so long as you pick the right fiber, skip the cheap processed stuff, and maybe add a light wax coat if it’s gonna be in a damp or pest-heavy environment.

If you’re tired of losing product to bugs, or your current wood paper packaging isn’t cutting it, hit us up. No long contracts, no hidden fees, just samples you can test in your own space, and we’ll work with you to get something that works. I’m the one who answers the emails, too—no random sales team bot, just me, [Your First Name], sitting at my desk with a pile of paper samples and a coffee that’s gone cold.
