By the end of this post, you’ll know how to tell if you have termites in walls like a pro. The following seven signs indicate that termites have invaded your home.
You will end up spending a lot of money on both termite treatment and damage repair if you don’t pay attention to these signs.
It’s for that reason that this post is both a life-saver and a money-saver for you.
What are the 7 termite signs in walls?
If you thought that wood was the only material that could be damaged by termites, think again. Termites can destroy entire walls, clothing, and even books if they infest your home deeply and widely.
Is it possible to tell if your walls are infested with termites? Termites cause damage to walls if they are detected at the earliest possible stage.
Termites inside walls can be detected by seven subtle signs –
1 – Tiny pinholes on walls
Pinholes can appear on both a standard wall and even on drywall. Pinholes are eviction points for frass and dead termites.
Through these pinholes, termites eject the dirt that they make while drilling inside the walls.
2 – Tube-like tunnels or marks on the drywall
Termites love drywall, so it’s a real treat if it’s present in your home.
Drywall is made from paperboard that contains cellulose. Termites feed on cellulose as their main source of nutrition.
Fibers, wood, and paper are composed of cellulose. Termites eat these materials. Tunnels like these on drywall may indicate that termites are chewing and tunneling through it.
These faint lines become more prominent when the infestation becomes severe. The drywall will show you the entire route of the tunnels.
There are times when you can see termite mud tubes rising from the ground on the walls, especially on the exterior walls.
3 – Tap on the wall and you hear an empty hollow sound
When you observe the first two signs, tap on the wall. When you hear a hollow sound, it confirms the presence of termites in the walls.
As a result, the walls are being eaten away from the inside by termites. As a result, your home is becoming more and more infested.
4 – The paint on the walls is flaking off
Termite-infested walls appear to have water seeping inside them. There is a sudden appearance of water soaking into the wall.
The surface of the wall starts to be covered with bubbles. The paint begins to peel off from different areas of the wall.
How does that happen?
The moisture reaches the surface of the wall when the wall becomes hollow. Moisture evaporates when heat is applied. Evaporated water seeks to escape.
Thus, the lumps on the wall are caused by that. Eventually, the paint peels off the wall. It also dulls the wall’s luster and makes it appear damp.
5 – Cracks in the wall’s baseboards
Do you think termites would have spared the baseboards if they had gotten up to the wall?
Termites attacking homes underground are called subterranean or ground termites they must have crawled up the wall from the bottom when they are inside the walls.
They must have crawled up the wall from the bottom when they are inside the walls. The baseboards are usually the first to suffer from termite damage.
On the baseboard, cracks will appear. If you tap gently on the baseboard, the baseboard can even break.
You will definitely hear a hollow sound if the baseboard isn’t sealed properly. When you have a wooden floor, the combination is disastrous.
A termite infestation begins at the baseboards and spreads upwards. A wooden floor that has been damaged by termites will buckle when you walk on it.
Carpet or rugs that show signs of termite damage are often the first indication that a wooden floor is infested.
6 – Frames of doors and windows lose grip on walls
The wall around the door and the window frame anchors become weak due to termites inside. This causes the doors and windows to wobble. Their original positions are displaced.
As a result, the doors and windows are difficult to close and open. As well, you would notice a slight tilt, either to the left or to the right, on the doors and windows.
But that’s not all.
Doors and window frames can also be infested by termites coming from the walls. It will also become hollow from the inside after they eat it.
7 – Termite Dust At The Walls’ Base
Dust can be found at the base of the walls. Termite feces and wall dirt are both present in the dust. The termites expel these particles from the pinholes.
As well as termite dust, this dust is known as wood dust. This dust is also commonly found beneath wooden furniture and structures.
Termite dust looks very different from fine sawdust from wood. Termite feces are included in termite dust.
Therefore, you’ll see tiny black pepper-like particles in the dust. If you do that, you’ll get the look of dirty sand with little black pebbles.
They can also be early signs of termites in the walls. Being at the early stages of the infestation, you won’t notice these signs unless you specifically look for them.
4 Signs Of Drywood Termites In Wooden Walls
Termites can cause damage to a standard brick wall when they get inside subterranean.
Termites in the US that cause the most damage are the subterranean termites and their cousins, the Formosan termites.
Damages worth billions of dollars are caused by them. Primarily, these termites attack wooden materials and walls from underground.
But there’s another kind of termite that flies into your house. It’s known as a dry wood termite. Infestations in the upper part of your home are more likely to occur as the insects fly in.
So they primarily target things like beams, joists, timbers in the roof, and ceilings inside your home, such as wooden beams and joists.
They are hard to detect because of this. Damage caused by them is also hard to detect. In contrast to subterranean termites, drywood termites do not require moisture to survive.
The colonies of their nests are smaller than those of subterranean termites. It might be too late by the time you notice the damage or realize their presence.
A wooden wall or structure may exhibit the following four signs of drywood termite damage –
- Under the wood, there is frass.
- Tapping on the wood or structure produces a hollow sound
- Tunnels visible on the surface of the wood
- The floor is covered with termite wings
When you can clearly see tunnels on the surface of wood, the infestation has worsened.
It could also indicate that drywood termites have hollowed out the wood from the inside and are now at the surface.
As a result, the wood becomes so brittle that a light punch will break it. The broken wings on the floor are from swarmers of drywood termites.
Swarmers like these are alates. Alates are reproductive termites who leave their old nests or colonies to search for a new home.
When they get inside a home, they mate, lose their wings, and start a new colony by drilling inside the wooden structure.
