Bonteheuwel is a close-knit, densely built suburb boxed in by the railway line, the Epping industrial area and busy roads. Pest problems here mostly come down to shared walls, backyard rooms and drains that struggle in winter.
The local picture in Bonteheuwel
German cockroaches are everywhere in the flat blocks, travelling along pipes from one kitchen to the next. American cockroaches come up through drains when the system backs up after rain.
Rows of semi-detached council houses and three-storey flat blocks make up most of Bonteheuwel, and many families have added Wendy houses or brick rooms at the back. Every shared wall and joined roof is a route for mice and German cockroaches, so one neighbour's problem soon becomes the next one's. The flats have communal stairwells and refuse points where rats feed at night.
It is flat, sandy Cape Flats ground, so winter downpours sit in yards and back up drains for days. The Epping industrial area next door has warehouses and food plants, and rats move freely between the two. Summer brings the South-Easter, which blows litter against walls and into corners.
Rats and German cockroaches are what people ask us about most. Fleas and bed bugs follow, because houses are full and pets live close to people. Flies around refuse points and mosquitoes after the winter floods are seasonal.
Tell-tale signs
- Yellowish stains or tiny pepper-like droppings are left on paper and shelves.
- Silvery, fast-moving insects are seen when you lift boxes, books or linen.
- Shed scales and skins collect in drawers, cupboards and bathroom corners.
- Fishmoths drop from the ceiling or come out of light fittings and cornices, a sign they are living in the roof space.
Something most people miss
When a technician deals with fishmoths, the first place they look is up. The roof space is often where the main population lives, out of sight, especially with the grey silverfish common in Cape Town.
How the treatment works
Fishmoths often live in roof spaces, wall voids and behind cornices, so a fine insecticidal dust blown into the ceiling void is one of our most effective tools. Inside, we apply a targeted residual treatment into cracks, cupboard corners, skirting gaps and behind bookshelves rather than spraying open surfaces. Fishmoths are long-lived and lay eggs in hidden cracks, so treatments that keep working for a while are more useful than a quick knockdown. We pair the treatment with advice on damp, ventilation and storage, because changing the conditions is what stops them coming back.

Keeping them out afterwards
- Avoid stacking old newspapers, magazines and cardboard boxes in cupboards for long periods.
- Seal cracks around skirting boards, cornices and built-in cupboards where they hide and lay eggs.
- Improve ventilation in bathrooms and laundries with an extractor fan or by keeping a window open after showers.
- Fix leaks under basins, around geysers and in the roof, since fishmoths need moisture.
- Vacuum regularly inside cupboards, along skirting boards and behind furniture to remove eggs and food sources.
What affects the price
The price depends on the size of the property, how many rooms and cupboards are affected, and whether the roof space needs to be treated. Easy access to the ceiling void keeps the job simpler, while a home with lots of built-in cupboards and shelves takes more time. Offices, archives and storerooms with large amounts of paper are quoted separately, and every quote is free.
Fishmoths are active all year because they live indoors, but Cape Town's damp winters make them more noticeable as moisture rises in roofs, walls and cupboards. Grey silverfish in the roof space may become more visible in summer when the ceiling heats up and pushes them down into the rooms below.
Questions we get asked in Bonteheuwel
Do fishmoths bite?
No, they do not bite people or pets and do not carry disease. The problem is the damage they do to paper, books, photographs and fabrics.
Can you treat a whole block of flats in Bonteheuwel for cockroaches?
Yes, and that is the best approach, because cockroaches move along shared pipes and walls. Treating every unit at once gives a much longer-lasting result.
Do rats in Bonteheuwel come from the Epping industrial area?
Some do, since warehouses and food plants nearby give them food and shelter. Most, though, live along the railway line and around refuse points, so treating close to home matters most.
Do fishmoths mean I have damp?
Often, yes. Common silverfish in particular need high humidity, so seeing them regularly in one room is a good reason to check for leaks or poor ventilation.
Can fishmoths damage clothes?
They can graze cotton, linen, silk and starched fabrics, particularly items stored for long periods in damp cupboards. They are less of a problem on synthetics.
Do you come out to Bonteheuwel for fishmoth control?
Yes. Bonteheuwel is part of our regular Cape Flats route, along with Langa, Bishop Lavis, Epping, Elsies River. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
