If you’re thinking, my neighbour has termites should I be worried, the short answer is yes – but not necessarily panic-level worried. Termites do not respect fence lines, and if one property has an active infestation, nearby homes can also be at risk. The good news is that early action makes a big difference, especially when you know what to look for and how to respond.

Why your neighbour’s termite problem matters

Termites are always searching for food, moisture and suitable nesting conditions. In many cases, they travel underground and stay hidden for long periods. That means your neighbour’s visible termite issue may be only one part of a bigger local problem.

If termites are active next door, it can point to favourable conditions across the area rather than a problem isolated to one house. Shared soil, similar building ages, garden beds against walls, leaking taps, timber retaining walls and damp subfloors can all increase the chance of movement between properties. This is especially true in built-up suburban areas where homes sit close together.

That said, your level of risk depends on more than distance alone. The type of termite, the size and location of the colony, construction style, moisture issues and whether your home has existing protection all affect the real threat.

How termites spread from one property to another

When people imagine termites spreading, they often picture them crawling directly from one house into the next. Sometimes the reality is less obvious. Subterranean termites, the most destructive type for homes, usually move through soil and build mud shelter tubes to stay protected while travelling.

A colony may be located in a tree stump, garden bed, retaining wall or underground well away from the house itself. Worker termites then branch out in search of timber. So if your neighbour has termites in a fence, pergola or wall frame, it does not always mean the nest is inside their home. It may be somewhere both properties can be affected by.

This is one reason termite activity nearby should never be brushed off as someone else’s problem.

My neighbour has termites – should I be worried if I can’t see any at my place?

Yes. Termites are often found after they have already caused damage, not when they first arrive. By the time you can see hollowed timber, bubbling paint, sagging architraves or mud tubes, they may have been active for months.

No visible signs does not mean no activity. Termites prefer dark, humid, hidden areas such as wall cavities, subfloors, roof voids and areas behind built-in cabinetry. A home can have a serious termite issue while looking completely normal from the outside.

This is where a professional termite inspection becomes valuable. It helps identify not just active termites, but also conditions that make an attack more likely. For families, pet owners and landlords, that peace of mind matters just as much as finding damage.

Signs your property could already be at risk

If your neighbour has reported termites, it is worth checking your own property for warning signs. Some clues are obvious, while others are easy to dismiss as normal wear and tear.

Watch for hollow-sounding timber, tight-fitting doors or windows, rippled paint, soft skirting boards, mud shelter tubes on walls or piers, and unexplained cracks in timber trims. Outdoors, inspect fences, old sleepers, tree stumps, timber edging, pergolas and stored firewood. Also pay attention to moisture. Leaking gutters, poor drainage and air-conditioning runoff can make an area far more attractive to termites.

Even if you spot none of these issues, the sensible move is still to arrange an inspection if there is confirmed termite activity close by.

What increases or lowers your risk

Not every neighbouring termite case means your house is under immediate attack. Some properties are much more vulnerable than others.

Your risk is generally higher if your home has a lot of timber in contact with soil, poor ventilation under the house, drainage issues, older construction, concealed entry points or no recent termite inspection history. Gardens built up against weep holes and slab edges can also hide termite entry.

Risk may be lower if your home has a current termite management system, well-maintained drainage, good subfloor airflow and regular inspections. Even then, lower risk does not mean zero risk. Termite barriers and treatments reduce the chance of attack, but they still need monitoring.

What to do right now

The best response is practical and timely. Start by confirming what your neighbour is dealing with if they have shared that information. Was it active termites, old damage, or a preventative treatment? That context helps, but it should not replace your own inspection.

Next, resist the urge to spray around suspect areas with supermarket insecticides. DIY chemicals can disturb termites and cause them to move deeper into the structure or spread into new areas, making detection harder.

Book a professional termite inspection as soon as you can, especially if your property is attached, close-set or has a history of moisture issues. A proper inspection looks beyond surface damage and checks the places termites actually use.

It is also smart to reduce risk factors straight away. Remove timber scraps from under the house, keep garden beds clear of weep holes, fix leaks, improve drainage and avoid storing timber against external walls. These steps do not replace treatment, but they can make your property less inviting.

Can fences, gardens and trees carry termites between homes?

Absolutely. A shared timber fence is a common concern, and for good reason. Fences, retaining walls, sleepers, decking and landscape timbers can all act as food sources and pathways. Trees and old stumps are another overlooked issue, especially if there is decaying wood below ground.

In many Sydney suburbs, homes also have dense gardens, mature trees and outdoor timber features that create ideal hidden zones for termite foraging. You may not see termites inside the house straight away because they often establish themselves in external timber first.

That is why a termite inspection should include the broader property, not just internal rooms.

Should you tell your strata or property manager?

If you live in a strata property, townhouse complex or duplex, yes. Shared walls, common gardens and connected structures can increase the chance of spread. Strata managers and property managers need to know quickly so they can arrange inspections and meet their maintenance responsibilities.

If you are renting, let the property manager know in writing if there is confirmed termite activity next door or if you have noticed signs on the property. Tenants are not expected to diagnose termite issues, but reporting concerns early is the responsible step.

For landlords, acting quickly helps protect the building and can prevent much higher repair costs later.

Why early inspections save money and stress

Termites are not just a pest problem. They are a structural risk. Repairs can become expensive because damage often affects hidden framing, skirtings, architraves, flooring and internal linings before anyone realises what is happening.

An inspection is usually far less costly than delayed repairs. It also gives you a clear picture of whether you need treatment, ongoing monitoring, or simply a few preventative changes around the property. For many households, that clarity is the biggest relief.

A good pest professional should explain what they found in plain language, outline any treatment options clearly, and recommend family-safe solutions where appropriate. That matters if you have children, pets or concerns about unnecessary chemical exposure.

When the risk is urgent

There are times when the situation should be treated as urgent rather than routine. If you can see live termites, mud tubes, fresh damage, swarming insects indoors or sudden changes in timber features, do not wait. Fast assessment can limit further damage.

Urgency is also higher if your home shares a wall with the affected property, if there has been previous termite history, or if moisture issues have been ongoing. In those cases, same-week action is a wise move.

For homeowners on the Northern Beaches and nearby Sydney suburbs, local knowledge can make a real difference because termite pressure, construction styles and environmental conditions vary from area to area. Companies such as Clean & Green Pest Control focus on practical, family-safe termite advice that protects both the property and the people living in it.

The bottom line if your neighbour has termites

So, my neighbour has termites should I be worried? Yes – worried enough to act, not worried enough to assume the worst. A neighbouring infestation is a clear signal to check your own home, reduce risk factors and get professional advice before damage becomes visible.

Termites are quiet, persistent and expensive when missed. The most sensible response is early inspection, honest information and a plan that protects your home without adding unnecessary stress to your household.
