Funnel ants are ground-dwelling insects named after the funnel-shaped entrances they construct above their nests. These mounds often appear in clusters after rainfall, typically in sandy or well-drained soils. While funnel ants rarely enter homes, their nesting behaviour can become a serious problem for lawns, golf courses, parks, and paddocks.
They’re particularly active after wet weather, when the moist soil makes it easier for them to excavate. Unfortunately, their tunnels can compromise soil structure, which is especially problematic in areas with foot or vehicle traffic, such as driveways, footpaths, and even under concrete slabs.
Are Funnel Ants Dangerous?
While funnel ants are not aggressive toward humans and don’t typically bite unless provoked, they do pose risks:
-
Lawn Damage: Their nesting activity can ruin the aesthetic and structural integrity of your turf.
-
Trip Hazards: The soft, unstable ground around their nests can collapse underfoot.
-
Property Risk: Their underground tunnelling can undermine concrete slabs, paving, and driveways over time.
Signs of a Funnel Ant Infestation
-
Numerous small, conical mounds of loose soil scattered across your lawn, especially after rain.
-
Soft, unstable patches of ground around the mounds.
-
A sudden increase in ant activity outdoors, especially on dry, sunny days following wet weather.
