Small, agile rodent commonly found in Gauteng homes, lofts, and commercial kitchens.
Environmental significance In natural habitats mice are prey for owls, snakes, and small carnivores, and they help disperse seeds. Indoors they have no beneficial role and should be excluded and controlled.
Large burrowing rat common in sewers, bin stores, and ground-floor areas.
Environmental significance Wild rodent populations form part of food webs for raptors and predators, but urban Norway rats thrive on human waste and sewers. Those populations have no beneficial role near homes or food businesses and should be controlled with proofing and targeted baiting.
Agile climbing rat often found in roofs, warehouses, and older buildings across South Africa.
Environmental significance In natural veld they can play a role in seed dispersal and as prey for raptors. Indoors and in food premises they have no beneficial role and require proofing and control.
Grassland rodent that can move into gardens, outbuildings, and suburban fringe properties in Gauteng and beyond.
Environmental significance Important native grazer in grassland ecosystems and a food source for owls and snakes. Control should focus on exclusion and habitat management rather than broad outdoor poisoning near veld.
Common South African grassland mouse that occasionally enters homes, lapa areas, and storerooms.
Environmental significance A native species that supports predators such as owls, snakes, and small carnivores. Indoors it should be excluded; outdoor populations are normal in natural grassland.
Major pest of South African food businesses and waste areas.
Environmental significance Outdoors, fly larvae help break down organic waste and recycle nutrients. Indoors and around kitchens they contaminate food and must be excluded with sanitation, screens, and targeted treatment.
Biting fly linked to discomfort and mosquito-borne disease risk across South African summers.
Environmental significance Aquatic larvae feed fish, dragonfly nymphs, and other predators. Adults pollinate some plants. Near occupied buildings, breeding sites should be removed and personal protection used during peak activity.
Large metallic fly attracted to meat, carcasses, and waste — common around bin stores and abattoirs.
Environmental significance Important decomposers in natural ecosystems. Indoors and in food premises they must be excluded with screens, waste discipline, and targeted treatment.
Small fly breeding in fermenting fruit, drains, and bar areas — a common kitchen and hospitality pest.
Environmental significance Outdoors they help break down rotting fruit. Indoors control focuses on removing breeding sites rather than sprays alone.
Blood-feeding fly that bites people and livestock, common near manure, compost, and kraals.
Environmental significance Part of decomposition cycles in agricultural settings. Breeding material should be managed and protected areas treated where flies persist.
Social wasp that nests in eaves, lofts, and gardens — peak activity in late summer across Gauteng.
Environmental significance Wasps hunt caterpillars and other insects, providing natural pest control in gardens. Nests on occupied buildings usually require professional treatment.
Fast-breeding cockroach — the main pest species in SA kitchens.
Environmental significance Outdoor cockroaches can help break down decaying plant and animal matter. German cockroaches in buildings are entirely dependent on human food and harbourage, with no positive ecological role indoors.
Common ant species trailing into kitchens and patios across SA suburbs.
Environmental significance Garden ants aerate soil, disperse seeds, and prey on other insects outdoors. Trails into kitchens should be controlled at the nest and entry points without unnecessary outdoor spraying of natural foraging areas.
Large, slow-moving cockroach found in drains, basements, and cool damp areas of South African buildings.
Environmental significance Outdoors it helps break down decaying organic matter. Indoors it has no beneficial role and should be controlled alongside proofing and moisture management.
Tiny tropical ant that nests indoors in hospitals, hotels, and multi-unit buildings across South Africa.
Environmental significance A commensal species with no positive role indoors. Outdoor populations are uncommon compared with garden ants.
Blood-feeding parasite spreading through hotels, guest houses, and residential moves in South African cities.
Environmental significance No beneficial role in human dwellings. Control requires inspection, laundry protocols, and targeted treatment of harbourage.
Common pet flea that bites people and persists in carpets, pet bedding, and garden sand across SA suburbs.
Environmental significance Natural parasite of mammals outdoors. Indoors and on pets they require integrated pet treatment and premises spraying or vacuuming.
Fabric pest whose larvae damage wool carpets, upholstery, and stored textiles in South African homes.
Environmental significance Outdoors larvae help break down dead insects and animal material. Indoors they damage valuables and require cleaning, proofing, and targeted treatment.
Silvery scavenger insect found in bathrooms, roof spaces, and stored paperwork across humid SA regions.
Environmental significance Decomposes cellulose and mould in natural settings. Indoors they are a nuisance pest controlled by drying, decluttering, and residual treatment.
