About Mice in South Africa
The House Mouse (Mus musculus domesticus) is the most common mouse species infesting South African homes, followed by the Pygmy Mouse (Mus minutoides) in rural and peri-urban areas. Mice are far smaller than rats — they can squeeze through a gap as small as 6mm — and are highly adaptable, feeding on almost anything available.
Mice prefer the warmth and shelter of walls, roof voids, kitchen cupboards, and storage areas. They are primarily active at night and forage within a small radius of 3–9 metres from their nest. Unlike rats, mice are curious and will investigate new objects quickly — which actually makes trap placement more effective when done correctly.
A single female house mouse can produce up to 8 litters of 5–6 pups per year. In a warm South African home, breeding is nearly year-round, meaning that what starts as one or two mice can become a serious infestation of hundreds within a few months.
🇿🇦 South African Facts
- Mice are responsible for destroying an estimated 10–15% of global food supplies annually.
- House Mouse infestations peak in South Africa during winter months (May–August) as mice seek warmth indoors.
- Mice produce up to 70 droppings per day — posing a significant contamination risk in food storage areas.
- Mouse urine contains allergens that can trigger asthma in children.
Warning Signs of a Mice Infestation
Spotting a mice infestation early can save you time and money. Watch for these tell-tale signs:
Small droppings (3–6mm, rod-shaped) in cupboards, along walls, or in food storage areas.
Gnaw marks on food packaging, cables, and soft furnishings.
Scratching sounds from walls, roof voids, or under floorboards at night.
Nests made from shredded paper, fabric, or insulation material found in quiet corners.
A musky, ammonia-like smell in confined spaces from mouse urine.
Small footprints visible in dusty areas or flour left on counters as a test.
Health & Property Risks
Spread of Salmonellosis and Leptospirosis through droppings and urine contaminating food surfaces.
Electrical fires from gnawing through wire insulation in walls and roof voids.
Contamination of food stores in homes, restaurants, and warehouses.
Triggering of asthma and allergic reactions from mouse fur and urine proteins.
Damage to insulation, clothing, documents, and personal belongings stored in roof spaces.
Our Mice Treatment Approach
At Eco-Fumigation, we follow a proven, multi-step process to fully eliminate mice and prevent their return.
Inspection & Species Identification
We identify the species, locate nesting sites, and map active runs and entry points throughout the property.
Snap Trapping
Strategic placement of high-quality snap traps along active mouse runs — the most immediate and effective initial control measure.
Rodenticide Bait Stations
Tamper-resistant bait boxes placed in inaccessible locations provide continuous knock-down over 1–3 weeks.
Proofing & Exclusion
All entry points — gaps around pipes, under doors, in brickwork — sealed with appropriate materials to prevent re-entry.
Sanitation Guidance
Our technician advises on storage, hygiene, and structural improvements to reduce future infestation risk.
