Carpenter Ants in Perth: How to Spot and Remove Them Safely
Carpenter ants are big, black ants that make their nests in wood. They don’t eat timber like termites do, but they make tunnels by hollowing it. This weakens structures and furniture. In Australia, particularly in hot Perth suburbs, carpenter ants can easily become household pests. Understanding their signs can help you stop damage from becoming too severe while also being proactive in its prevention.
How to Identify Carpenter Ants
Carpenter ants are some of the biggest ants. They range in length from 6–12mm, are moulded in a dark black or very dark red and make a slight rustling noise while inside walls. Signs of infestation include:
Sawdust-like shavings near woodwork
Small holes in timber surfaces
Rustling noises inside the walls
They are attracted by wet or rotting wood that is commonly found in:
Roof voids and wall cavities
Decking and fences
Window frames and skirting boards
Tree stumps near homes
Why Carpenter Ants Are a Concern
Left untreated, they can hollow out beams, floors, and furniture. This weakens the structure and reduces property value. In Perth’s humid seasons, they expand colonies faster, especially in older wooden homes.
Find the nest track worker ants back to the entry points.
Lower the humidity by repairing leaks and increasing ventilation.
Treat with ant bait or dust products labelled for carpenter ants.
Replace damaged wood after treatment.
Seal up cracks and give wood a fresh paint job.
When to Call Experts
Carpenter ants may construct secondary nests in a secluded location. They are persistent and destructive. Early detection, moisture control, and professional help are key to long-term protection.
