About Moles in South Africa
South Africa's most commonly encountered problem mole species are the Cape Golden Mole (Chrysochloris asiatica) in the Western Cape, and the Highveld Mole (Cryptomys hottentotus) found across Gauteng, Mpumalanga, and the Free State. Despite their similar name, these are very different animals — the Golden Mole is a true insectivore that feeds on earthworms and beetle larvae, while the Highveld Mole (a mole rat) is a rodent that feeds on underground plant roots, tubers, and bulbs.
Both create extensive tunnel and burrow systems that devastate lawns, flower beds, vegetable gardens, golf courses, and sports fields. Mole hills — mounds of soil pushed up from excavations — can number in the dozens across a garden following a single night's activity. The tunnel systems undermine root systems, cause irrigation pipe damage, and create dangerous trip hazards on sports turf.
Moles are protected under South African nature conservation legislation in most provinces and must be managed humanely — trapping and relocation is the preferred and often legally required approach.
🇿🇦 South African Facts
- The Cape Golden Mole is listed as Vulnerable on the South African Red Data List — making lethal control legally complex.
- A single Highveld Mole can produce over 30 mole hills per night when establishing a new tunnel system.
- Mole rats (Highveld Moles) live in colonies of up to 14 individuals — making population control challenging.
- Mole tunnel systems in South African gardens can extend 50–200 metres in length.
- Mole activity peaks in autumn and spring when moist soil conditions make tunnelling easier.
Warning Signs of a Moles Infestation
Spotting a moles infestation early can save you time and money. Watch for these tell-tale signs:
Mole hills — cone-shaped or flattened mounds of loose soil pushed up in lawns and garden beds.
Soft, spongy ground when walking — indicating tunnel networks just below the surface.
Uplifted lawn turf along tunnel ridges, creating raised, uneven lines across the lawn.
Missing bulbs, tubers, and plant roots — characteristic of Highveld Mole (mole rat) feeding.
Surface tunnels visible as raised ridges across the lawn after rain.
Health & Property Risks
Lawn and turf destruction — mole activity undermines root systems causing yellowing and dieback.
Loss of bulbs, tubers, vegetable roots, and ornamental plants from root feeding.
Damage to underground irrigation pipes from tunnelling activity.
Trip hazards from mole hills and tunnel collapses on sports fields and pathways.
Significant financial losses to golf courses, bowling clubs, and sports grounds.
Our Moles Treatment Approach
At Eco-Fumigation, we follow a proven, multi-step process to fully eliminate moles and prevent their return.
Mole Activity Assessment
We identify the species, map active tunnel systems, and assess the extent of infestation before selecting the most appropriate control strategy.
Humane Trapping & Relocation
Live traps are placed in active tunnels — moles are trapped humanely and relocated to suitable natural habitat well away from the property. Preferred method for protected species.
Tunnel Fumigation
Aluminium phosphide fumigant tablets are placed in active tunnel systems — releasing phosphine gas that controls moles within the tunnel network.
Repellent Application
Castor-oil based repellent granules or vibrating sonic stakes are placed to deter moles from treated areas — most effective as a preventive or supplementary measure.
Habitat & Prey Modification
Where earthworm populations are exceptionally high (the primary food source), soil treatment to reduce earthworm density can deter moles without directly targeting them.
