Before you panic, let's get the basics right. Yes, termites eat plasterboard. Not the plaster itself, but the cardboard that surrounds it. And this nuance changes everything when it comes to understanding the problem, detecting it and, above all, treating it.<\/p>\n<h3 id=\"ce-qu-il-faut-retenir\">Things to remember<\/h3>\n<ul>\n<li>\n<p>This article goes beyond simple confirmation of presence to explore the biological relationship between termites and BA13 cellulose.<\/p>\n<\/li>\n<li>\n<p>Based on entomological data, we offer a precise diagnostic guide to distinguish termite damage from other pests, affirming the authority of Pest Patrol<\/p>\n<\/li>\n<li>\n<p>Why do termites attack plasterboard and BA13?<\/p>\n<\/li>\n<li>\n<p>How can you identify the signs of infestation in your partitions?<\/p>\n<\/li>\n<\/ul>\n<p>What most articles don't tell you is that plasterboard is actually an open-air buffet for termites. BA13, the board found in 90% of French homes built or renovated since the 70s, contains exactly what these insects are looking for: cellulose. Let's take a look at why they attack, how to spot an infestation before it becomes catastrophic, and what solutions actually work.<\/p>\n<p>At Pest Patrol, we take a no-nonsense approach to the subject. No unnecessary jargon, no vague answers. Just what you need to know to protect your home.<\/p>\n<h2 id=\"pourquoi-les-termites-s-attaquent-ils-au-placoplatre-et-au-ba13\">Why do termites attack plasterboard and BA13?<\/h2>\n<p>To understand the problem, we need to go back to a simple biological fact: termites don't eat wood by chance. What they are looking for is cellulose. Cellulose is an organic polymer found in all plant fibers. Wood contains it, paper contains it, cardboard contains it. And guess what? Plasterboard is stuffed full of it.<\/p>\n<p><img decoding=\"async\" class=\"max-w-full h-auto rounded-md\" src=\"https:\/\/nghaeknymynesecnqcmd.supabase.co\/storage\/v1\/object\/public\/article-images\/article-1780380282298-termites-et-placo-platre-signes-dangers-et-solutions-durables.png\" alt=\"Termites and plasterboard: Signs, dangers and sustainable solutions\"><\/p>\n<p>Standard BA13 plasterboard consists of a core of gypsum (calcium sulfate) sandwiched between two sheets of recycled cardboard. Termites don't touch gypsum. They're not interested in it, they can't digest it. Cardboard, on the other hand, is a perfect meal. Entomological studies, notably those carried out by the CTBA (Centre Technique du Bois et de l'Ameublement, now FCBA), have shown that subterranean termites of the genus <em>Reticulitermes<\/em>, the most widespread in mainland France, actively consume all cellulose-containing materials, including plasterboard paper linings.<\/p>\n<p>In practical terms, termites arrive through the floor. They work their way up the foundation, through the lining, and into your partitions. Once on the plasterboard, they nibble away at the cardboard, often from the inside, without you seeing a thing for months. That's what makes the infestation so vicious: the surface may look untouched, while the back of the panel is completely eaten away.<\/p>\n<p>One thing many people don't know: termites don't just feed on solid wood. They attack everything in your home that contains cellulose. Books stored against walls, cardboard frames, cellulose insulation and, of course, plasterboard. A colony of <em>Reticulitermes flavipes<\/em> (the most common species in France, according to the FCBA) can number several hundred thousand individuals. Each worker consumes a few milligrams of cellulose a day, but multiply that by 300,000 individuals and you get structural damage in just a few months.<\/p>\n<p>Another aggravating factor is humidity. Subterranean termites need high levels of humidity to survive. A poorly ventilated wall, an undetected water leak behind a partition, a damp crawl space: these are all conditions that favor their progress. Plaster absorbs moisture, maintaining a favorable environment right next to their food source. They don't even have to return to the floor as often.<\/p>\n<p>So yes, termites do damage plaster walls. Not by eating the plaster, but by methodically destroying the cardboard that gives the board its rigidity. A BA13 plasterboard whose cardboard has been consumed loses all mechanical strength. It warps, cracks and eventually collapses if no one intervenes.<\/p>\n<h2 id=\"comment-identifier-les-signes-d-une-infestation-dans-vos-cloisons\">How can you identify the signs of infestation in your partitions?<\/h2>\n<p>A homeowner once showed me photos of his wall and said, \u00abI thought it was mold.\u00bb In reality, what he saw were earthen cords, the little tunnels of dried mud that termites build to move around sheltered from light and dry air. This is one of the first visible signs of termite infestation, and probably the most reliable.<\/p>\n<p>Termite cords look like fine lines of earth or mud, a few millimeters wide, running along walls, baseboards or corners. They are made up of soil, saliva and excrement. If you find them on your drywall, there's an active colony. Not \u00abwas active\u00bb. Is active. Termites don't build cords for fun: they're their highway between soil and food.<\/p>\n<p>Termite holes in plasterboard are often tiny, on the order of one or two millimeters in diameter. They don't resemble the holes left by termite beetles, which are more regular and rounder. Termite holes are irregular, sometimes with a light deposit of earth at their base. Beware, these xylophagous plaster insects work from the inside out: when you see holes on the surface, the damage behind is already well advanced.<\/p>\n<p>Another sign to watch out for: tap gently on your partitions. A hollow sound where it shouldn't be is suspicious. Termite galleries in the wall create voids behind the paper, and the board sounds different. Some professionals use acoustic detectors to detect termite activity through the walls.<\/p>\n<p>Paint that blisters for no apparent reason is also a clue. Termites consume the cardboard under the paint, leaving it unsupported and bubbling. I've seen cases where the owner has punctured a blister thinking it was water damage, only to discover a network of galleries right behind it. Not very reassuring, but at least the diagnosis had been made.<\/p>\n<p>What insect eats drywall, apart from termites? This question is often asked. Termites and beetles attack wood, not plasterboard. Cockroaches may nibble wallpaper, but they don't dig galleries in BA13. If you find structured galleries in your partitions, with traces of soil, it's termites. Point.<\/p>\n<p>One last detail that may help: winged termites. In spring, between April and June in Belgium, reproductive termites fly off to found new colonies. If you find small translucent wings on your windowsills or at the foot of your walls, this is a serious alarm signal. These wings fall off after swarming and remain on the ground. Don't confuse them with those of flying ants, which have wings of unequal size (termites have four wings of equal length).<\/p>\n<h2 id=\"quels-traitements-choisir-pour-eliminer-les-termites-de-vos-murs\">What treatments should you choose to eliminate termites from your walls?<\/h2>\n<p>Let's face it: if you've confirmed a termite infestation in your partitions, you're not going to solve it with a commercial insecticide spray. These products kill the individuals on the surface, but never the colony. And it's the colony that needs to be eliminated, otherwise the termite damage in your home will continue.<\/p>\n<p>Today, the treatment of subterranean termites is based on two main approaches: termite traps (or baiting stations) and chemical barriers. Both work, but not in the same way and not in the same situations.<\/p>\n<p><strong>Termite traps<\/strong> is the method most widely used in France over the last twenty years. The principle is elegant: stations are placed in the ground around the house, containing a cellulose-based bait impregnated with a growth regulator (such as hexaflumuron or diflubenzuron). Workers find the bait, take it back to the colony, and share it by trophallaxis (mouth-to-mouth food exchange). Within a few weeks to a few months, the product prevents the termites from moulting, eventually decimating the entire colony. The FCBA recommends this approach for confirmed infestations, as it targets the source of the problem and not just the symptoms. Follow-up usually lasts two to five years, with regular checks.<\/p>\n<p><strong>The chemical barrier<\/strong> involves injecting a termiticide product (often fipronil or bifenthrin) into the soil, around and under foundations. This creates a toxic zone that the termites can't cross without dying. It's effective for protecting a building, but doesn't necessarily destroy the colony if it's at a distance. The chemical barrier is often used as a complement to traps, or when access to the ground around the house is limited.<\/p>\n<p>For partitions already affected, damaged plasterboard often has to be removed. A BA13 plasterboard whose cardboard has been eaten away is no longer tenable. It can't be \u00abrepaired\u00bb. Remove it, treat the area (including the framing wood, if it's a wood stud partition), and install new plasterboard. Some professionals recommend using fiberglass-faced plasterboard rather than cardboard in high-risk areas. Termites don't consume fiberglass. It's a modest extra cost for real peace of mind.<\/p>\n<p>What's the budget? Treatment with termite traps costs between 1,500 and 4,000 euros, depending on the surface to be protected, including annual follow-up. A chemical barrier costs around 2,000 to 5,000 euros. It's not cheap, but compare that to the cost of replacing all your partitions and potentially your roof timbers. The cost-benefit ratio is indisputable.<\/p>\n<p>What about prevention? Eliminate sources of humidity (leaks, capillary rise, insufficient ventilation). Avoid storing wood or cardboard against exterior walls. Have your home inspected every two or three years if you're in a high-risk zone. A termite diagnosis costs between 100 and 200 euros. It's the best investment you can make.<\/p>\n<h2 id=\"conclusion\">Conclusion<\/h2>\n<p>Termites don't eat plaster, but they do devour the cardboard that holds your BA13 boards together. The result is the same: weakened partitions, costly repairs, and stress that nobody deserves. The signs are there if you know where to look: cords of dirt, tiny holes, blistering paint, hollow sounds when you tap on the wall.<\/p>\n<p>If you have the slightest doubt, don't waste time looking for miracle solutions on the Internet. Call in a certified professional for a diagnosis. The earlier an infestation is detected, the less time and money it will take to treat it.
