What Are The Signs of Termites?

Termites may be small, but they’re one of the most destructive pests you can encounter in your home. I’ve seen firsthand how a quiet termite infestation can go unnoticed for months, slowly causing significant damage to a property’s structure. That’s why recognising the early signs of termites is so important. The worst part? When many homeowners realise they have a problem, the damage can run into thousands of dollars in repairs.

This blog is here to help you spot the warning signs early. Whether in Melbourne’s leafy suburbs or the Mornington Peninsula, understanding how to detect termites can save you a lot of stress and money. 

8 Common Signs Of Termite Infestation

1. Mud Tubes (Shelter Tubes): The First Clear Indicator

The first signs I always recommend people look for are mud or shelter tubes. If you’ve ever heard someone mention them in passing, you might not think they’re that big of a deal. But tell me from experience — if you find them, it’s time to get serious. These tubes are one of the most obvious signs that termites are active in your home. They’re typically made up of dirt, saliva, and debris, and they act as a safe pathway for subterranean termites as they travel between their nests and food sources.

I’ve found mud tubes running up the side of concrete foundations and even along interior walls hidden behind skirting boards. I remember one client’s home in Seaford where we found a series of these tubes weaving through the garage and into the roof beams. What seemed like a minor issue on the surface turned out to be a major infestation waiting to cause serious damage.

Where to look: Check along exterior walls, foundations, and wooden structures. They often go unnoticed in cracks and behind furniture, so don’t overlook the spaces you don’t normally inspect. If you spot mud tubes, it’s almost certain you have termites at work.

2. How To Detect Termite-Inflicted Wood Damage

You’re particularly vulnerable if you’ve got timber structures, especially those in contact with the soil (think wooden decks or supports). Termites love wood, but they don’t eat it like we would a snack. They’re experts at eating wood from the inside out. You might notice some of the wood feeling soft or spongy when you press on it, or even worse, it might sound hollow when you knock on it.

I’ve been called to homes in areas like Cranbourne where clients noticed the floorboards squeaking and buckling underfoot. After a quick inspection, we found extensive damage beneath the surface. It’s one of those signs that’s easy to miss until it’s too late.

Where to look: Focus on areas where timber meets soil, such as around decks, wooden fences, and joists. You’ll often find termites love rotting or untreated wood. In some cases, termite damage might look like water damage, so it’s easy to miss. If you notice soft wood, tiny holes, or splintering timber, it’s a red flag.

3. Flying Termites And Their Wings

Seeing flying termites, or “swarmers,” is never a good sign. These guys are the reproductive termites; when you spot them, your infestation has matured. I’ve had clients in areas like Richmond, where they noticed a sudden influx of flying termites near their lights during the warmer months, and that’s when things started to get serious. After they swarm, these termites shed their wings, which is often another indicator.

Where to look: Look for the discarded wings — often in piles near windowsills, doors, or anywhere they may have flown in. Flying termites are attracted to light so you might spot them around outdoor lights or even indoor lamps.

4. Termite Droppings (Frass): The Silent Warning

Now, many people don’t realise that termite droppings, also known as frass, are a serious clue. You might think it’s just dust or debris, but if you find small piles that look like sawdust, coffee grounds, or even pepper, you could be dealing with drywood termites. These little pests live inside the wood, and as they eat, they push out their waste.

I once worked with a client in St Kilda who found tiny pellets around a wooden window frame. After a quick inspection, we determined they had a drywood termite infestation. These pests tend to be a little sneakier, but their droppings are a surefire sign.

Where to look: Look around infested wood, near tiny holes in the wood, or on window sills. If you notice small piles, examine the woodwork closely, especially if the wood feels soft or crumbly.

5. Struggling Doors And Windows: Unexpected Clues

Have you ever walked into a room and found that your door or window suddenly feels a little “stuck”? It might not just be the humidity, as is often the case in Melbourne’s fluctuating weather. This could be a subtle but crucial sign of termite activity. Termites don’t just eat the wood — they can warp it too.

I’ve had customers in places like Chelsea and Elwood tell me about doors that suddenly wouldn’t close properly. They thought it was a simple alignment issue or the result of a damp season. However, after a more thorough inspection, we found the real culprit: termites had been feeding on the door frames and weakening the structure.

As termites munch away, they weaken and warp the wood around the door and window frames. This moisture damage can make the wood swell, making it difficult to open or close windows and doors.

Where to look: Check areas around door frames, window sills, and anywhere timber meets the structure. If these areas are hard to open or feel different to the touch, it’s time to call in an expert.

6. Bubbling Paint And Peeling Wallpaper: A Sign Of Termite Activity

Peeling paint or wallpaper can be more than just an aesthetic issue. In my line of work, this is often a sign of moisture caused by termites tunnelling beneath the surface. When termites feed on the wood, they create moisture, which can eventually cause the paint to bubble or peel.

The paint will appear uneven, sometimes bubbling or flaking off. Small holes may also be in the paint, indicating where termites have chewed through the surface.

I once worked with a homeowner in Oakleigh who called us after noticing their kitchen paint started peeling around the window trim. They thought it was simply age-related paint damage, but after our inspection, it turned out that termites had been working silently behind the scenes for months. The paint was just the outward sign of a much bigger problem.

Where to look: Check the paint and wallpaper around doors, windows, and wooden trim. Bubbling or cracked paint could mean termites are tunnelling beneath, making it a prime spot to inspect.

7. Distinctive Sounds: Quiet Clicking Or Munching

Have you ever been in a quiet room and heard a faint clicking from your walls? It sounds a little eerie, but that could be termites at work. I’ve been to many homes in Melbourne where clients mention hearing strange sounds late at night — soft clicks or faint rustling — and while it seems like it could be something else, it’s often a tell-tale sign of termite activity.

Soldier termites, the colony’s protectors, will bang their heads against wood or shake their bodies as a warning signal to the rest. On the other hand, worker termites make a subtle munching sound as they feed on the wood. These sounds are usually faint but can be heard if you listen closely, especially in quiet areas like attics or basements.

Where to look: Focus on areas where termites are likely active, like walls, attic spaces, and behind wooden panelling. If you hear a tapping or faint crunching sound, don’t ignore it — it might just be termites letting you know they’re there.

8. Visible Termites: The Unmistakable Warning

While termites are mostly secretive and elusive, occasionally, you’ll see them. And trust me, if you spot them, it’s time to take immediate action. These tiny, soft-bodied pests can range in size from 1/4 to 3/8 inches and are typically pale in colour.

I’ve had clients in areas like Fitzroy and Port Melbourne spot termites crawling along walls or even flying around in their homes. It’s uncommon, but when it happens, it’s often a sign that the infestation has advanced.

Seeing termites inside your home is an unmistakable warning sign that they’ve been active for a while. These pests often enter through cracks in the foundation or walls, and once they’re inside, they can quickly establish a colony and wreak havoc on your property.

Where to look: Focus on areas where wood is in contact with the soil, like foundation walls, crawl spaces, and attics. If you spot live termites in these areas, you’re likely dealing with an advanced infestation that requires immediate attention from a professional.

What To Do If You Spot Signs Of Termites

How To Prepare For Professional Termite Inspection

Don’t wait around if you notice any of the signs listed above. The best thing you can do is call in a local pest control expert. A professional termite inspection involves a thorough check of your property, from the foundation to the roof, and they have the tools to find the infestations you might miss. In my experience, people who act quickly can often prevent the damage from escalating.

What to expect during an inspection:

Step	What Happens
Initial Assessment	The professional will start by assessing the visible signs of termite activity around your home, including mud tubes, damaged wood, or frass (droppings).
Hidden Inspection	They’ll then check less visible areas, such as behind walls, in crawl spaces, and under floors. They’ll use tools like moisture meters, thermal cameras, and sometimes sound sensors to detect hidden termite activity.
Detailed Report	After the inspection, the technician will provide a detailed report, highlighting the areas of concern and the severity of the infestation.
Treatment Recommendation	Based on the findings, they’ll suggest the best action, including baiting systems, liquid treatment, or fumigation.

 

Preparing your home:

Action	Why It’s Important
Clear access points	Ensure easy access to areas where termites are likely to hide (e.g., under furniture, near baseboards, and crawl spaces). The pest control expert needs to reach these spots for a thorough inspection.
Remove obstructions	Remove any clutter around the exterior of your home to make it easier for the technician to check areas like the foundation and walls.
Prepare for treatment	If the technician recommends a treatment plan, you may need to clear the area of furniture or cover it to prevent contamination. This ensures the treatment is applied effectively and safely.

Professional Treatments: The Best Approach To Eliminate Termites

Once the infestation is confirmed, professionals can recommend the best treatment options, which might include baiting systems, liquid treatments, or fumigation, depending on the severity of the problem. I’ve had the opportunity to see firsthand how these treatments work to eliminate termites and prevent future infestations.

Why professional treatment is essential:

Treatment Option	Description
Liquid Termite Treatment	This involves applying a liquid termiticide around the perimeter of your home, which creates a barrier to kill termites as they cross it. It’s highly effective in preventing termites from entering the property.
Termite Baiting Systems	Bait stations are installed around the home and monitored regularly. These contain food that attracts termites. Once they feed on the bait, they carry it back to the colony, killing other termites.
Fumigation	Fumigation is used in severe infestations where termites have infiltrated multiple areas. It involves sealing the structure and releasing gas to eliminate the termites. Although it’s a more invasive process, it is often the only solution for heavy infestations.

Steps for treatment:

Step	What Happens
Initial Consultation	The pest control service will provide a consultation and assess the level of infestation.
Treatment Plan	Based on their assessment, they’ll recommend the most suitable treatment method: liquid treatments, baiting, or fumigation.
Follow-Up	After the initial treatment, they’ll schedule follow-up visits to ensure the treatment was effective and the termites are completely eradicated. Regular inspections may be recommended.

Preventing Termite Infestations: Tips For Homeowners

Moisture Control: The First Line Of Defence

One of the best ways to prevent a termite infestation is to control the moisture levels around your home. Termites, particularly subterranean termites, thrive in damp environments. In Melbourne’s climate, where we can experience heavy rainfall and humidity, moisture control is vital in keeping termites at bay.

How to do it: Regularly inspect your home for plumbing leaks, clear gutters, and ensure proper drainage. If areas like a crawl space or basement are damp, consider installing a vapour barrier to reduce moisture levels.

Keeping Wood Away From The Ground

Termites thrive in areas where wood comes into direct contact with soil, so it’s crucial to ensure that wooden structures are elevated and properly sealed. I’ve seen many homes in suburban Melbourne with wooden posts directly into the ground, providing easy access for termites.

How to do it: Install barriers like metal flashing or concrete bases beneath wooden posts. Elevating outdoor timber structures can also prevent direct contact with the soil.

The Importance Of Annual Termite Inspections

Even if you’ve taken all the necessary steps to prevent termites, it’s still important to have your home professionally inspected annually. Termites can sneak into the most unexpected places, and a trained professional can spot the early signs you might miss.

Termite infestations are often silent, but the damage they cause can be loud and costly. Early detection is the key to saving both your property and your wallet. From mud tubes to damaged wood, flying termites, and frass, recognising the signs of a termite problem early can prevent severe structural damage. 

Whether you’re a homeowner or renting, staying vigilant and arranging regular professional inspections is crucial. If you spot any signs, don’t hesitate to call in a pest control expert to assess the situation. It’s always better to catch termites early than face expensive repairs later.
