Termites aren’t like other pests that invade your home. You don’t see the evidence of their presence or can you listen to the noises they make while going about your daily lives. Instead, termites silently feed on the timber structure of your home and can go unnoticed for months or even years.
At Specialist Termite Control, we understand how quickly termites can multiply if left untreated. We also know how much destruction they can do to your property in a short space of time.
Exactly how fast termites can eat through a home is a commonly searched term. The truth is that most people searching this aren’t looking to learn out of curiosity. If you’re reading this you may already be worried you have termites, or are taking steps to learn how to get rid of termites.
The best thing you can do if you’re worried termites are in your home is to call in the professionals. Scheduling a termite inspection will confirm whether termites are detectable or not. The earlier you can detect them, the better chance you have of nipping the problem in the bud.
By the time you know termites are there, you might have a full-blown problem on your hands. What could have been solved quickly may have evolved into structural termite damage that can cost you thousands of dollars to repair.
On this page, we’ll cover how much wood termites will eat in a year, factors that affect how fast they eat, and how to detect the early warning signs.

How Much Wood Can Termites Eat in a Day, Month, and Year?
Most homeowners have a notion that termite damage will take years to become severe. In fact, termites are hard at work all year round — and the speed at which they can destroy your home can vary based on the size of the colony, climate, and what attracts the termites to your house initially. Wood that is in contact with soil, excessive moisture, exposed untreated timber, and concealed entry points can increase the speed at which termites establish themselves and begin causing damage.
It may help to look at termite damage over a timeline to see how quickly a minor issue can become major structural damage.
Termites Eating Wood Per Day
Individually, termites do not eat large quantities of food, but they don’t have to. A termite colony can house hundreds of thousands to millions of termites all consuming food around the clock. One colony with approximately 250,000 termites can devour up to half a kilogram of wood each day. Although half a kilogram doesn’t seem like a lot, this erosion is happening 24 hours a day, typically within walls, flooring or support beams out of sight.
Since they consume wood from the inside out, the outer surface may appear completely unaffected while the inner wood is being eaten away. This means half a kilogram of damage may occur each day without anyone even realising it.
Monthly Termite Damage Explained
Within a month, this regular feeding begins to multiply. Small pockets of damage can become larger areas of softened wood. In a matter of weeks, termites can burrow further into structural wood, reach into other areas of the home and increase consumption as numbers in the colony increase.
At this point you might start to see your first hints of termite damage. Doors and windows that seem tight, or walls that seem slightly buckled. Environmental factors will also come into play around this time. If there is high moisture content in your home or vulnerable access points, spread can occur at a quicker rate. These factors knowingly encourage termite activity by sustaining their livelihood.
Yearly Termite Damage: The Bigger Picture
Left unchecked for 12 months termites can do some serious damage. They can eat through hundreds of kilograms of wood each year including structural support beams, floorboards and framework. Visible signs of damage can range from fractured or buckled wood work or even whole areas where the wood has been hollowed out.
Even worse is that termite colonies continue to grow as time goes by. With more termites comes more damage. A small local problem can soon become major structural damage that is costly to repair.
Why Do Termites Eat Wood?
Why do termites eat wood? Termites eat wood because they have to. Their entire diet consists of wood and other cellulose-based materials. Cellulose is the natural fibre found in wood and other plant life that allows termites to survive. Since most animals can’t break down the cellulose found in wood, termites are the perfect predator to keep wood structures in check.
Termites have adapted to be able to digest wood. They have microbes in their gut that allow them to break down wood fibres and use them as energy. Other items that contain cellulose such as cardboard, paper and even some fabrics become food for termites as well.
They not only eat the wood, they build their colony in it. Wood supplies them with a food source and when in contact with dirt or moisture, a place to call home. Damp wood, wood close to the ground, and improperly ventilated wooden areas are at risk of termite infestation. If there is a plentiful supply of cellulose, termites will eat through it and establish a long-term residence.
Do All Termites Eat Wood at the Same Rate?
Different species of termites won’t damage your home at the same rate. Feeding rates will vary depending on the species involved, colony size and even their life cycle stage. Subterranean termites are considered the worst when it comes to damage in Australian homes due to their ability to amass large colonies which stay permanently connected to a moisture source (the ground).
The most aggressive species, such as the coptotermes acinaciformis termite, build colonies containing hundreds of thousands or even millions of worker termites. So with hundreds or thousands of termites feeding simultaneously, the rate of wood consumption can become exponential, resulting in serious structural termite damage over a short amount of time.
Dampwood termites are attracted to wood with high moisture content such as rotten wood, tree stumps and water-damaged timber. While species like the naustitermes exitosus termite aren’t usually found in well-maintained houses, they can be just as culpable for ongoing timber loss. Their feeding rate will be slower than others, however it is heavily dependent on environmental conditions.
As we touched on earlier, colony size has a big impact on the rate of consumption. Smaller colonies will cause minimal damage and often go unnoticed. As colonies reach maturity and produce large numbers of worker termites (only worker termites will feed), the rate of destruction will take off.
What Does Termite Damage Actually Look Like?
One unfortunate thing about termites is that you may not always know you have damage. Termites consume wood from the inside out, and damage caused by termites may look fairly innocuous (in the beginning).
Wood can look intact but when you knock on it, it sounds hollow or like paper. In fact, this might be one of the first indications you have — listening for what termite damage sounds like is just as important as looking for it. Over time, as termites continue to eat away at the inside of wooden structures, it weakens the wood to the point that the outer surface can collapse with even a little pressure.
Paint will blister or bubble up. Many people think this is the result of water damage when in fact it can be caused by termites eating away wood that’s just beneath the surface of the paint. Door frames, skirting boards, and window sills may appear warped or not quite straight.
You may see mud tubes. These are thin tunnels made of dirt and are typically located along foundations, walls, and subfloor areas. They allow termites to travel safely and keep them humid. Inside your home you will see rippling or cracking in wood that has been damaged by termites. If you break the damaged wood it will look like a maze.
How Quickly Can Termites Damage a House?
Speed of destruction can vary based on where termite activity is around your house. Places with constant moisture near accessible timber are at highest risk. Common areas include subfloors, wall cavities, roof voids and foundations. Termites feeding in these concealed areas can go unnoticed for years.
Typically, damage will start off small and within a localised area. After six-12 months the growing colony can expand through multiple feeding sites going through structural timber as they go. Years of this can weaken beams, cause floors to sag and result in unsafe living conditions.
Termites are only a threat because of their persistence. They never stop eating and large colonies mean faster damage. If left untreated small colonies can cause extensive damage that is much more expensive to repair.
Signs Termites Are Already Eating Wood in Your Home
Spotting the early warning signs of termites can be the difference between a small problem and thousands of dollars of structural damage. Since termites consume wood from the inside out, these signs can be easy to miss. However, there are several things homeowners should keep an eye out for.
If you notice any of the above, your home may have active termites eating away at wood in your home:
| Sign | What It Looks Like | What It Could Mean |
| Hollow-Sounding Wood | Timber sounds empty when tapped or feels thin/fragile. | Internal termite damage where they’ve eaten the wood from the inside out. |
| Mud Tubes On Walls or Foundations | Thin, dirt-like tunnels along walls, brickwork, or subfloor areas. | Active termite pathways used for moisture and protection. |
| Tight-Fitting Doors or Windows | Suddenly harder to open or close. | Moisture buildup from termite activity is warping the wood. |
| Blistering or Bubbling Paint | Paint appears uneven, cracked or slightly raised. | Damage beneath the surface, and is often mistaken for water issues. |
| Discarded Wings | Small, translucent wings near windows, doors or floors. | Termite swarmers have entered your home,and are probably in other areas. |
| Frass (Termite Droppings) | Tiny, wood-coloured pellets resembling sawdust. | Evidence of termites actively feeding inside timber. |
| Clicking Sounds In Walls | Faint tapping or rustling noises. | Soldier termites reacting to disturbance or workers chewing wood. |
| Cracked or Damaged Timber | Visible cracks, sagging or weakened wood structures. | Advanced termite damage is compromising structural integrity. |
How to Stop Termites Before Serious Damage Occurs
The key to avoiding costly repairs is acting early. While termites are highly persistent, there are a few practical steps you can take to strengthen your home’s termite protection and reduce the risk of an infestation taking hold.
Reduce moisture in and around your home by fixing leaking pipes and ensuring good drainage and ventilation of below the subfloors. Dry timber is less attractive to termites so ensuring these areas of your home are well ventilated will help to deter them. Limiting wood-to-soil contact will also help; giving termites fewer ways to enter your home undetected.
While these steps can help reduce risk, termites are incredibly difficult to fully prevent without professional support, which is why ongoing termite monitoring and expert guidance play such an important role.
Professional Termite Inspections: Why Early Action Matters
The earlier you deal with termites, the better. Tens of thousands of dollars can be saved by nipping the problem in the bud. And since most termite damage occurs behind walls and under floors, a professional inspection is the best way to determine if you have activity on your property.
Many people ask us, how often should I get a termite inspection done? Unless your property is at high-risk, we advise annual inspections. Regular check-ups are the easiest way to spot activity early on, before colonies have the chance to build up and expand.
Inspections from Specialist Termite Control will always focus on more than just trying to find evidence of termites. Once we know the potential risk factors, entry points and access to your property we can look for the conducive conditions and how to reduce them. From there it’s easy to select the appropriate treatment options.
We can help you with everything from termite baiting systems that attack the colony from within to chemical treatments that protect the soil around your home.
