Moles
The European mole (Talpa europaea) digs up to 20 m of tunnels per day. It devastates lawns, vegetable gardens and root structures while remaining partially protected under Belgian regulations.

A carnivore (earthworms, grubs), the mole doesn't eat plants but destroys their roots as it digs. Molehills disfigure green spaces and sports grounds. Professional trapping is the most effective method — sonic repellers have very limited effectiveness.
Identify
Signs of infestation
- Mounds of fresh soil (molehills) appearing overnight on a lawn or garden
- Linear ground heaving forming ridges beneath the lawn surface
- Collapsed tunnels creating irregular dips up to 5 cm deep
- Loose black soil pushed to the surface, different from the topsoil layer
Where it's found
The European mole (Talpa europaea) occupies loose, moist soil rich in earthworms: well-kept lawns, vegetable gardens, fields and meadows. It digs two networks: shallow (hunting) and deep (permanent tunnels at 20-40 cm). Solitary and territorial, each individual covers 400 to 1,500 m².
Impact
Associated risks
Lawn and ground damage
Molehills and tunnels make surfaces uneven and hazardous. On sports fields and recreational areas, subsidence is a trip and fall risk.
Agricultural and horticultural damage
Tunnels dry out the roots of surrounding crops. In meadows, molehills contaminating hay with soil increase the risk of bovine listeriosis.
Foundation erosion
A dense tunnel network near light foundations can destabilise edging, low walls and paved paths on loose soil.
Good practice
Prevention
- 01No chemical or vibration repellent is scientifically validated at scale. Only professional trapping delivers lasting results
- 02Keeping vegetation short and well-drained reduces soil attractiveness but isn't enough on its own
- 03In vegetable gardens: mole-proof mesh sunk 30 cm deep around critical areas
Frequently asked questions
What you're asking
Are moles protected in Belgium?
In the Walloon and Brussels Regions, the mole is partially protected and trapping is subject to conditions. In Flanders, the regulations differ. Antinox identifies the applicable legal framework before any intervention.
How do I stop mole damage on my lawn?
Professional trapping is the most effective method. Sonic or vibration repellers have very limited, unproven effectiveness. For professional grounds (golf courses, parks), physical protection solutions can be considered.
How many tunnels does a mole dig?
A solitary mole digs 15 to 20 m of tunnels per day and maintains a territory of 1,000 to 3,000 m². Visible molehills are just the spoil exits — the underground network is far more extensive than what shows at the surface.
