7 Signs of Termites in Drywall with Pictures & DIY Treatment-2022

Many people who have drywalls in their homes have to face termites at times.

Drywalls include two substances that attract termites, the first is cellulose and the second is clay.

Drywalls contain up to 10% cellulose and the rest are other substances.

In addition to cellulose, clay is also found in drywalls. And in many pieces of research, it has been found that clay also helps in the survival of termites.

Termites can be very destructive if they are not controlled at an early stage.

That’s why today we will tell you about the early and late signs of termites in drywall, if you recognize these signs and stop them at an early stage, then you will be able to easily protect your drywalls from termite’s destruction.

Along with the signs of termites in drywalls, we will also tell you how you can effectively treat termites on drywall through some DIY methods.

So without delay let’s start. Read this article carefully so that you do not miss any important points.

Signs of Termites in Drywall With Pictures (Early Signs & Late Signs):

Early signs of termites on drywall include:

  1. Bulging on the surface of the drywall
  2. Discoloring paint
  3. Hollow wall sound and
  4. Wet stains on the drywall.

Late signs or major infestation signs of termites on drywalls include:

  1. Appearance of mud tubes on drywalls
  2. Termites flying through the drywall
  3. Sawdust or frass near the drywall etc.

Let us now know about these signs in detail.

Bulging on The Surface of Drywall:

The place where termites are inside the drywall, retain moisture in that place with their excreta. And because of this moisture, you often see bulging on your drywall surface.

These type of signs is caused by the Drywood termites, which suck the cellulose from your drywalls inside and hollow them out.

Discoloring Paint:

This is also an important early sign of termites in drywall. When termites build up too much moisture inside the drywalls from their excrement, the paint of the drywall starts to discolor.

The discoloration of paint from drywall can also be caused by water leakage. Therefore, you should also check that there is no leakage around your drywall.

Hollow Sound in Drywall:

This sign also indicates that there is a termite infestation in your drywall. Whenever you knock or tap on your drywall surface, you hear a hollow sound.

When termites eat the cellulose paper of drywall, a gap is created between the surface of the drywall and the solid material. And when you knock on that specific gap area you hear a hollow sound.

Many times people ignore this type of sign And over time, termites can completely hollow out your drywalls. By the time you realize it, it is too late.

So if you hear this kind of hollow sound on your drywalls, then you should get it checked by an exterminator.

Wet Stains on Drywall:

Such wet stains on the drywall also indicate the presence of termites.

The place behind drywall surface where termites gather in large quantities. You can get to see such wet stains at that place.

When termites are in large numbers behind drywall, they retain moisture from their feces to survive in that location.

Due to the hollowing of the place where the cellulose of the drywall is eaten by termites, this moisture starts appearing on the surface of the drywall.

If you look carefully, you will see the shape of a mapped tunnel in these wet stains.

These four were some of the signs that point to an early infestation of termites in drywall. Now we will talk about some of the major signs which point towards a widespread termite infestation.

Mud Tubes on Drywall:

Mud tubes tunnel-shaped tubes produced by termites to help them carry food from their food source to their colony.

Not only this, but these mud tubes also prevent the outside air from coming in so that the moisture does not dry up and the termites can survive.

The appearance of mud tubes on drywall is not a good sign; it may indicate an infestation of subterranean termites. Which if not treated on time can cause a lot of damage.

Flying Termites Coming Out of the Drywall:

If you see tiny holes in your drywall with flying termites coming out, that’s also not a good sign.

This sign indicates that now the infestation of termites in your house is going to increase further.

When the number of these termites increases significantly behind their colony in drywall and there is no more food and space left, they come out through tiny holes to find a new colony and food.

When they come out they breed and during that process, their wings are developed.

As soon as you see these tiny holes in your drywall, you should be alert and treat them immediately.

Sawdust or Frass Near Drywall:

When termite feces accumulate in large quantities in the termite colony present in the drywall, then these termites throw their feces towards the outside through tiny exit holes. The excreta of these termites look just like sawdust. Sometimes their broken wings are also visible along with their feces.

The appearance of termite feces in this way also indicates that their infestation is about to increase or has already spread a lot, now you should treat it immediately.

Now we have learned what are the signs of termites on drywall. Now we will know how to treat termites in drywall effectively without hiring any professional.

How to Treat Termites in Drywall:

Most people try to defeat these termites with natural methods such as vinegar, baking soda, bleach, etc.

But let me tell you that these natural methods are not effective at all on drywalls, ceilings, or termites hiding under the ground.

Because natural methods do not reach hidden termites, they can only kill termites at the contact level. In such a situation, we need something that can reach these hidden termites and kill them effectively.

So let’s go through some of the methods that experts recommend to get rid of termites in drywall, walls, or ceilings.

Spectracide Terminate Killing Foam2:

There are very few termiticides that can help you get rid of termites on drywall. Out of all the termiticides we experimented with, this termiticide gave the best results.

The best feature of this termiticide is that it expands completely inside the drywall and successfully kills the hidden termites.

We have also tried using Termidor Foam on drywalls, but Termidor foam expands well on brick walls but does not expand well inside drywalls. Therefore, if you want to get rid of termite infestation on drywall, then this is a very good termiticide.

A lot of people have given it a lot of positive reviews on Amazon too. And this foam works very effectively not only on termites but also on Carpenter Bees.

Note: Read all the instructions and precautions on the label before using it.

TERRO T1901-6 Termite Killer:

It is also a very effective termiticide for getting rid of termites on drywall. Its two-way spray nozzle penetrates into the crevices very well and attacks the hidden termites.

The second thing that I found good about it is that it is a non-staining formula and it does not have any odor at all.

You can use both of these not only indoors but also outdoors.

We have experimented with many termiticides but both of them have very good results and they do not cost much either. Both of these are the best treatment if you want to get rid of termites on your drywall.

After knowing how to get rid of termites on drywall, let’s move on to some of the questions that people get asked the most.


Do natural methods work on termite infestation in drywall?

Natural methods such as vinegar, baking soda, salt, etc. only affect visible termites, they cannot reach the termites hidden deep inside the drywall.

How to get rid of termites in drywall with a low budget?

Spectracide Terminate Killing Foam2 and TERRO T1901-6. These are two such termiticides that work especially well on drywall. Once sprayed, they expand deep inside the drywall and effectively kill hidden termites.

Why do termites attack drywall?

Termites attack drywall because they contain up to 10% cellulose and clay. Both of these substances attract termites. Second, even when there is moisture in the drywall, termites are attracted to the drywall.

How to protect drywalls from termites?

It has been observed that where there is more moisture, termites often thrive there. In such a situation, you should keep in mind that moisture does not come from anywhere on your drywalls, and as far as possible remove the old wallpaper from the drywalls. Because they also attract termites.

Can termites spread throughout the house from the drywall?

Yes, if termites have started coming out of the drywall and looking for a new colony for themselves, then they can make your home furniture their prey. You should treat them as soon as possible.

How much does it cost to treat termites on drywall?

If you hire a professional, then it costs a lot, but if you know the right termiticides that work on drywalls, then you can treat them yourself for very little money.


Whenever we treat any pest, we need to be aware of the signs of that pest, otherwise, our time, efforts, and money are wasted.

We hope that you will now be able to easily identify the signs of termites in drywall. We have shared here with you not only the Early Signs but also the Major Signs. If you can control the termite in drywall at an early stage, then they are not able to do much damage.

Both the termiticides mentioned above are quite effective for getting rid of termites on drywall. We also experimented with other termiticides but these two gave the best results. The most important thing about these two is that they kill the termites hiding completely inside the drywall and also prevent them from coming back.
