Signs of Termite Damage to Hardwood Floors
Termites have always been leading an extremely secret way of life thus representing a hidden danger for a man and his dwelling.
Termites are very difficult to identify: for years they can live and “work” in hard-to-get spaces of a house destroying it at ease.
The best possible food for termites is wood, thou they are willing to gorge with cloths, cardboard and paper. It is easy to understand, that wooden houses or houses with wooden floors and ceilings will be in high-risk group.
Can Termites Live Under the Floors? What Damage They Can Bring?
Old houses that have their floors lying on bare ground (sometimes with sawdust or dry moss between ground and ground joists for warmth keeping) are in real danger, because such veiled places with the soil contacting with wooden structures are perfect for termites’ relocation.
When termites have such an easy transfer from ground to floor, soon they will occupy the entire house.
Just in few years, termites are able to destroy wooden floor, though, destruction can progress throughout an entire house: it doesn’t necessarily mean, that, if termites eat a floor, they do not eat another wooden structures of a house: their colonies are able to spread further and further.
The pieces of damage, that can possibly be done to wooden floors are the following:
- rotten and decomposed grounds joists;
- rotten pillars that connect soil with ground joists (namely, support them);
- decomposed floor boards, that can collapse any time.
As a result, wood floor damaged by termites can sink and break that is very dangerous for those, who live inside a house.
Also, when pillars and joists are faulty (in neglected cases) the entire house can begin to slowly sink: because the floor boards are rotten, the walls are also coming down curving, that will trouble the whole system of roof timber that can cause the possible partial or complete fall of roof.
But it is the most dramatic scenario in very uncared cases and can occur when the houses are already uninhabited for many years, but it describes the major principle of house decomposition beginning with the floor caused by termites.

Signs of Floor Decomposition Caused by Termites. Where to Find Clues?
When you are making your regular inspection of house structures for termites’ activity, it will be a good idea to look under the floor if possible or if you have a basement that provides you an access to floor structures.
The mold. Mold can only appear in damp und stuffy places, where the water collects or where there is faulty ventilation system. Termites also like such places.
It is possibly to say, that termites and mold in some cases represent a distinct connection. Mold is stinking and can be gray, yellow, green, white or black.
The mold is the sign that the wooden structure has already began to decompose and you should carefully inspect it for termites’ activity.
The mud tunnels. Termites construct mud tunnels to transfer throughout the house to search for necessary food and moisture.
Also, these tunnels serve as shelter and help them to maintain their vital functions.
Mud tubes can extend from the soil to the very floor on walls or be horizontal. They are of the pencil width and dark-brown.
Termites feces. It can be found either under the floor or on the floor, frequently in the corners or behind plinths.
It means, that termites live and destroy your floor, and their frass is the consequence of their living activity that is released during mud tunnels construction. Frass is like the sawdust but brown in color.
Hollow-like empty wood or wood with small holes in it. Sometimes, destroyed wood can sound empty and dull, though it looks normal.
You can easily check it with the help of a screwdriver: just softly nock the wood and hear the outcome. There are neglected cases, when after the screwdriver inspection, the decomposed wood starts to crumble and break.
It means, that the ground joist, for example, is completely rotten and needs to be replaced.
Such decomposition and fragility could be caused by mold or termites.
If there are termites, you will see holes in the food, or the wood will seem layered with brown frass.
Warning: of course, if you have found such a rotten joist or floor board, you can try to sand it to “living tissue” and cover with special chemical against termites. But pay a close attention, whether the joist is load-bearing or not: in most cases it should be replaced anyway because it is very difficult to stop decomposition (termites or mold spores have already gone further in deeper wood fibers).
Damaged floor will be shaky and unstable: floor board will curve after a single step and easily crumbling like chips; plinths will come off the walls, some floor areas will be with frass looking untidy.
Also, some special anti-insect and anti-mold protective remedies are able to sufficiently slow down the process of decomposition.
What are the Signs of Severe Damage?
The floor is badly damaged when its wooden joists are partially or completely decomposed by termites. Such wood will sound hollow and easily crumble, becoming very fragile.
Such structures should be replaced, because they can cause a damage to the integrity of the whole house.
When there are wooden plinths that also start to be eaten by termites, the process of decomposition can spread to adjoining row of beams (if the house is also wooden) that could be very dangerous to the whole house.
In neglected cases, the whole wooden structures of a floor become faulty and dangerous to tread upon. Such floor should be rebuilt.

Termites is a real hidden pest that is very difficult to detect at an early age.
Termites begin their “journey” to our dwellings where soil is connected with the house – namely, from the floor.
Only regular inspections of a house along with preventive measures (covering floor with special lacquer, soil treatment near the house) can protect you against severe damage that could be very costly and painstaking to eliminate.
