Kensington has the feel of an old railway suburb, with modest homes on small plots, corner shops and warehouses never far away. Our work here is mostly rats, cockroaches and pigeons, and how bad each one gets depends a lot on how close you are to the industrial side.
Kensington: what drives crawling insects here
German cockroaches breed in kitchens and corner shops and move through shared walls. American cockroaches come up through old drains on hot nights.
Rows of older semi-detached and free-standing houses make up most of the suburb, many with pitched corrugated roofs and backyard rooms built over time. Some are a hundred years old in parts, with timber floors over shallow voids. Factories, workshops and storage units nearby add bigger buildings with loading bays, where rats are never short of a meal.
Norway rats along the railway and industrial edges are the main concern. German cockroaches follow in kitchens and corner shops, with pigeons on roofs and fleas in summer.
What gives them away
- Wallpaper is lifting or damaged along the edges where the glue has been eaten.
- Silvery, fast-moving insects are seen when you lift boxes, books or linen.
- Shed scales and skins collect in drawers, cupboards and bathroom corners.
- Clothing, curtains or linen made from cotton, linen or silk have small holes or thinned patches.
- Fishmoths drop from the ceiling or come out of light fittings and cornices, a sign they are living in the roof space.
- Yellowish stains or tiny pepper-like droppings are left on paper and shelves.
Fishmoths do not bite or spread disease, but they cause slow, steady damage. They eat the glue in book bindings and wallpaper, the starch in fabrics and paper, and the surface of photographs and documents. For offices, schools, libraries and archives, they can damage records that cannot be replaced. Their presence is also a strong clue to damp or poor ventilation that may be causing other problems in the building.
Something most people miss
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.

Keeping them out afterwards
- 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.
- Fix leaks under basins, around geysers and in the roof, since fishmoths need moisture.
- 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.
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.
Frequently asked questions
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.
Do rats in Kensington come from the Ndabeni and Epping industrial areas?
Some do. Warehouses and railway land give rats food and shelter, and they move into homes nearby, so we bait along the boundaries and seal entry points.
Why are fishmoths falling from my ceiling?
That usually means there is a population in the roof space. Treating the ceiling void with a dust is the most effective way to deal with it.
How do I stop pigeons nesting under my solar panels?
Mesh around the edge of the panels stops pigeons getting underneath without damaging the system. We can fit it and clear out existing nests.
Do you come out to Kensington for fishmoth control?
Yes. Kensington is part of our regular Northern Suburbs route, along with Maitland, Ndabeni, Pinelands, Epping. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
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.
