Termite Swarming Season: Why Spring Is the Best Time for a Termite Inspection in Melbourne

As the weather warms up, termites become more active, and spring is when many Melbourne homeowners first notice the signs. If you’ve spotted small winged insects around your lights, or piles of tiny discarded wings on a windowsill, it’s a good time to book a termite inspection in Melbourne.

Here’s why termites swarm at this time of year, what to look for around your home, and why a check now is far cheaper than dealing with damage later.

Why termites swarm in spring

Termite colonies grow quietly for years. Once a colony is mature, it produces winged reproductive termites, known as alates. When conditions are right, these alates leave the nest in large numbers to find a mate and start new colonies.

Those conditions are usually warm, humid and still, which is why flights tend to happen on muggy evenings, often around spring and summer storms. In Melbourne, activity can continue from spring right through the warmer months.

Most alates don’t survive, but the swarm itself tells you something important: there’s a mature colony somewhere nearby. That might be in a tree, a stump, a fence post, or your home.

Warning signs you can check for yourself

Termites avoid light and open air, so they’re rarely seen. Instead, look for the clues they leave behind:

• Discarded wings: small, similar-sized wings near windowsills, doors or light fittings.
• Mud tubes: pencil-width mud trails running up foundations, piers, brickwork or walls.
• Hollow-sounding timber: skirting boards, door frames or architraves that sound hollow when tapped.
• Bubbling or cracked paint: paint that looks blistered or wavy on timber surfaces.
• Sticking doors and windows: timber that has shifted or swelled due to termite activity and moisture.
• Mud in cracks or joins: packed mud where timber meets masonry.

If you find termites, don’t disturb them or spray them. Breaking open mud tubes or using a household spray can cause the colony to move elsewhere in your home, making it harder to find and treat.

Who’s most at risk in Melbourne?

Any home can be affected, but risk tends to be higher where there’s timber, moisture and nearby bushland. Homes in leafy suburbs like Eltham, Warrandyte, Ringwood and Frankston, and across the Mornington Peninsula, often have gum trees, old stumps or timber landscaping close to the house.

Other common risk factors include:

• Leaking taps, pipes or air conditioner drains that keep soil damp against the house.
• Garden beds, mulch or soil built up against external walls or covering weep holes.
• Timber fences, retaining walls or sleepers touching the house.
• Poor subfloor ventilation, which traps moisture.

What a termite inspection in Melbourne involves

A professional termite inspection is a thorough, non-invasive check of your property. Under Australian Standard AS 3660.2, inspections are recommended at least once a year, and more often in high-risk areas. A technician will typically:

• Inspect accessible areas inside the home, including skirting boards, door frames, window frames and wet areas.
• Check the subfloor and roof void, where access allows.
• Look over the exterior, fences, trees, stumps and garden features.
• Use tools such as moisture meters and, where appropriate, thermal imaging to detect hidden activity.
• Identify conditions that make your home more attractive to termites.
• Provide a written report with findings and recommendations.

What to do if you find termites

• Leave the area undisturbed, including any mud tubes or damaged timber.
• Don’t spray insecticide or try to remove the termites yourself.
• Take photos if you can do so without disturbing them.
• Book a professional inspection as soon as possible so the colony can be identified and treated properly.

Why inspecting now costs less than termite treatment later

Termites can cause significant structural damage before there are any obvious signs. By the time a floor feels spongy or a door frame gives way, repairs can be extensive.

Termite damage is also often not covered by standard home insurance policies, so it’s worth checking your own policy. An inspection costs a fraction of major repairs, and if activity is found early, termite treatment is usually simpler. Depending on what’s found, treatment options can include chemical soil barriers or termite baiting and monitoring systems, and your technician will explain which suits your property.

Simple steps to reduce your risk

• Fix leaking taps, pipes and drains around the house.
• Keep garden beds and mulch away from external walls and weep holes.
• Remove old timber, stumps and firewood stacked against the house.
• Keep subfloor vents clear so the area can dry out.
• Book a professional inspection at least once a year.
