Tamboerskloof climbs steeply up the slopes of Lion's Head and Signal Hill above Kloof Street. Old houses, tight streets and the mountain right behind them make it a suburb where rodents and timber pests are a fact of life.
Crawling insects around Tamboerskloof
American cockroaches come up through old drainage, and German roaches are a restaurant kitchen problem. Fishmoths thrive in damp bookshelves and built-in cupboards.
Victorian and Edwardian homes with wooden floors, sash windows and pressed-ceiling interiors sit beside newer apartment blocks and converted guest houses. Many older houses have suspended timber floors with a crawl space underneath, which rats and mice use as a highway. Kloof Street's restaurants and shops add a busy commercial layer at the bottom of the suburb.
Signal Hill and Lion's Head are part of the Table Mountain National Park, and the greenbelt reaches right to the top streets. Winter rain runs down the slope and keeps old basements and retaining walls damp. The suburb is sheltered from some wind, which lets flies and mosquitoes linger on warm evenings.
Tell-tale signs
- Clothing, curtains or linen made from cotton, linen or silk have small holes or thinned patches.
- 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.
Worth knowing
Many people think fishmoths only eat paper. They also go after the glue in wallpaper and book bindings, starch in fabrics, and even dried food crumbs and dead insects in cupboards.
Landlords with older rental properties often get fishmoth complaints from tenants. A roof void treatment and better ventilation in the bathroom usually solves it for the long term.
What happens when we come out
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.

Prevention that actually works
- Seal cracks around skirting boards, cornices and built-in cupboards where they hide and lay eggs.
- Avoid stacking old newspapers, magazines and cardboard boxes in cupboards for long periods.
- Vacuum regularly inside cupboards, along skirting boards and behind furniture to remove eggs and food sources.
- Store books, documents and photographs in sealed plastic boxes, not cardboard, especially in garages and storerooms.
- Improve ventilation in bathrooms and laundries with an extractor fan or by keeping a window open after showers.
How much will it cost?
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.
Fishmoth Control questions from Tamboerskloof
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.
My Tamboerskloof Victorian has small holes in the floorboards. Is it wood borer?
Small round exit holes with fine powder underneath are a classic sign of borer. We can inspect, confirm whether it is active and treat it, which also helps when you need a beetle certificate for a sale.
Do the rats in Tamboerskloof come from Lion's Head?
Some do, especially in the top streets near the greenbelt, but plenty also move between restaurants, bins and old homes lower down. Sealing roof and floor gaps on your house is the key step either way.
Are fishmoths and silverfish the same thing?
Yes. Fishmoth is the common South African name for silverfish, and it covers a few related species, including the grey silverfish common in Cape Town.
Do you come out to Tamboerskloof for fishmoth control?
Yes. Tamboerskloof is part of our regular City Bowl & Atlantic Seaboard route, along with Gardens, Higgovale, Bo-Kaap, Schotsche Kloof. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
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.
