How Often Should Perth Homes Have a Termite Inspection?
On this page 6
Many Perth homeowners assume that once a home has passed a termite inspection, or has a termite barrier in place, it is protected for years. Unfortunately, termites do not work that way. Colonies can find their way into a home in a matter of months, often without leaving any visible sign until the damage is done. Booking a regular Termite Inspection Perth homeowners can rely on is the most effective way to catch activity early and avoid costly repairs. For most homes, that means an inspection at least once every 12 months, and more often if your property is at higher risk. This guide explains why, and answers the questions Perth homeowners ask most about inspection frequency.
Do I Need an Annual Termite Inspection?
Yes. Every Perth home should have a termite inspection at least once a year. The Australian Standard for termite management, AS 3660, recommends regular inspections at least every 12 months, and more frequent inspections in high-risk areas.
Perth is a high-risk city for termites. Subterranean termites thrive in our sandy soils, mature trees and long warm season, and they are found in both established and new suburbs across the metro area. An annual inspection gives you the best chance of catching termites before they cause structural damage.
You should consider inspections every 3 to 6 months if your home:
| Risk factor | Why it increases risk |
|---|---|
| Previous termite activity | Colonies often return to properties they have attacked before |
| Close to bushland, parks or reserves | Termite colonies are common in natural areas and forage widely |
| Large trees, stumps or timber in the garden | These can host nests close to your home |
| Older or heritage construction | Timber floors, raised subfloors and timber framing give termites more to feed on |
| No termite barrier, or an old one | Termites have an easier, hidden path into the home |
| Recent renovations or landscaping | Works can breach existing barriers or create new entry points |
| Leaks, poor drainage or damp areas | Termites are attracted to moisture |
Your inspector can recommend the right schedule after assessing your property.
Can Termites Appear Between Inspections?
Yes. Termites can appear between inspections, which is exactly why regular inspections matter. An inspection gives you an accurate picture of your home on the day it is carried out, but it cannot stop a new colony from arriving later.
A mature subterranean termite colony can contain hundreds of thousands of termites, and workers can forage up to 100 metres or more from the nest looking for food. Each spring and early summer, winged termites leave established colonies to start new ones, so a property that was clear one year can be under attack the next.
The longer the gap between inspections, the more damage termites can do before they are found. Annual or more frequent inspections keep that window as short as possible. Between inspections, keep an eye out for warning signs such as:
- Mud tubes on walls, slabs or foundations
- Discarded wings near windows and doors
- Bubbling paint or timber that sounds hollow when tapped
- Doors and windows that suddenly stick
- Small patches of mud in cracks or joints
If you notice any of these, do not wait for your next scheduled inspection. Leave the area undisturbed and book an inspection straight away.
Are Newer Homes at Risk?
Yes. Newer homes are still at risk of termites, and this is one of the most common misconceptions among Perth homeowners.
Under the National Construction Code, new homes in termite-prone areas, which include much of Perth, must be built with a termite management system. However, this does not make a new home termite proof:
- Barriers are designed to deter hidden entry, not stop termites completely. A termite management system forces termites into the open where they can be detected during an inspection. Without inspections, that protection is far less effective.
- New estates are often built on cleared bushland. Termite colonies can survive in the soil, tree roots and stumps left behind after clearing.
- Landscaping can breach barriers. Garden beds, paving, retaining walls and soil built up against the slab edge are often added after the home is completed and can give termites a hidden way in.
- Modern homes still contain timber. Even steel-framed and double-brick homes have timber roof structures, door frames, skirting boards, cabinetry and flooring that termites can attack.
Many builders’ termite warranties also require regular inspections. If inspections are not carried out, you may not be able to make a claim if termites get in.
Does Having a Termite Barrier Remove the Need for Inspections?
No. A termite barrier does not remove the need for inspections. In fact, most termite management systems are designed to work alongside regular inspections, not replace them.
Here is why inspections are still essential with a barrier in place:
- Barriers deter concealed entry. Physical and chemical barriers are designed to stop termites entering your home unseen. Termites can still build mud tubes over or around a barrier, and an inspection is how that activity is found.
- Chemical barriers break down over time. Soil treatments lose effectiveness over a number of years, depending on the product, soil type and weather. Inspections help identify when a barrier needs topping up or replacing.
- Barriers can be breached. Renovations, extensions, new paving, garden beds, plumbing work and even covered weep holes can create gaps in the treated zone.
- Baiting systems need monitoring. Termite bait stations must be checked regularly to confirm whether termites are feeding and to replenish bait when needed.
- Warranties depend on inspections. Most barrier and baiting system warranties require inspections at set intervals, often every 12 months, to remain valid.
Think of a termite barrier like a security system. It is an important layer of protection, but it still needs to be checked and maintained to do its job.
How to Get the Most From Your Termite Inspections
To make each inspection as effective as possible:
- Keep access clear. Make sure the roof void manhole and subfloor access points are not blocked.
- Keep the slab edge visible. Avoid stacking items, building garden beds or laying soil against the outside walls.
- Fix leaks and drainage issues. Moisture attracts termites and makes it easier for colonies to survive near your home.
- Remove timber from the garden. Old stumps, sleepers, firewood and timber offcuts can attract termites close to the house.
- Keep your reports. Inspection reports provide a valuable termite history for warranty claims and when you sell.
