Occasional invaders,
handled before they cluster.
"Occasional invader" is the industry term for the seasonal nuisance species that turn up in large numbers without warning — Asian lady beetles aggregating on sun-facing walls in autumn, tiny red clover mites in spring, and the annual sticky invaders that cling to flyscreens and window frames. None are dangerous, but the numbers can be genuinely overwhelming. TCB treats the exterior ahead of the seasonal influx and seals the gaps that let them inside.
The signs that point to an occasional-invader problem.
Autumn wall aggregations
Asian lady beetles clustering in large numbers on sun-facing exterior walls in autumn, seeking a sheltered spot to overwinter.
Tiny red mites in spring
Clover mites — barely visible, bright red, moving in numbers across window sills, brickwork and paths, particularly after mild wet spring weather.
Clinging to flyscreens
A general band of small nuisance insects clustering on screens, window frames and light-coloured surfaces as the seasons turn.
Staining if crushed
Both ladybugs and clover mites can leave a stain if crushed against fabric or paint — vacuuming rather than crushing avoids this.

Two steps ahead of the seasonal cluster.
Occasional invaders arrive in a predictable seasonal window — the exterior barrier goes down ahead of it, and exclusion work closes off the gaps they'd otherwise use to get inside.
Seasonal exterior treatment
A residual perimeter barrier applied to sun-facing walls and known aggregation points ahead of the typical autumn or spring influx.
Exclusion
Sealing gaps around windows, eaves, vents and siding — the most effective long-term fix, since it stops entry regardless of outdoor numbers.
Indoor removal advice
Guidance on safe vacuum removal for any that make it inside, avoiding the staining that comes from crushing them.
Follow-up
If a fresh wave breaks through inside the guarantee window, we re-treat as part of that guarantee.
Occasional invaders are harmless — the numbers are the whole issue.
Not dangerous to people or pets
Neither Asian lady beetles nor clover mites bite, sting or carry disease — they're a nuisance and an aesthetic issue, not a health risk.
Genuinely seasonal, not constant
Aggregation events cluster tightly around autumn and spring — the rest of the year, these species are barely noticeable around most properties.
Exclusion beats spraying alone
Sealing entry points is more effective long-term than repeated spraying, since it stops the numbers from ever reaching the door.
Sun-facing walls are the hotspot
Both lady beetles and clover mites favour the warmest, most sun-exposed side of a building — that's usually where treatment matters most.
What keeps the seasonal numbers down.
Seal gaps before the season starts
Check weatherstripping, vents and eaves in late summer, ahead of the typical autumn lady beetle influx.
Vacuum, don't crush
Vacuuming indoor stragglers avoids the staining that comes from crushing them against fabric or paint.
Treat sun-facing walls first
If treatment is limited to one side of the building, the warmest, most sun-exposed walls are where the return is highest.
The questions Canberra households ask first.
Are ladybugs and clover mites dangerous?
No. Neither bites, stings or carries disease — they're a nuisance and a cleaning issue in large numbers, not a health risk.
Why do they appear in such large numbers all at once?
Both species aggregate seasonally — Asian lady beetles in autumn seeking overwintering shelter, clover mites in spring after mild wet weather. It's a predictable seasonal event, not a building infestation.
Will exclusion fully stop them?
Sealing gaps significantly reduces indoor numbers and is the most effective long-term fix, though some exterior wall activity is normal during the peak season regardless.
Will they stain my walls or fabric?
Both can leave a stain if crushed — vacuum removal rather than crushing avoids this, especially indoors on curtains or carpet.
How much does occasional-invader treatment cost in Canberra?
Usually priced as a seasonal exterior treatment, individually quoted based on the property. We send a written quote before any work starts.
