Fish Hoek is a beach town with a strong community, plenty of retirees and a flat valley that cuts right across the peninsula toward Noordhoek. A lot of our work here is helping people in older homes keep mice, fishmoths and ants under control without any fuss.
The local picture in Fish Hoek
Argentine ants are almost guaranteed in summer, and fishmoths love older cupboards and stored books. Houses near the slopes see scorpions and rain spiders now and then.
Most homes are freestanding mid-century houses with tiled roofs and established gardens, alongside retirement complexes, flats near the beach and the shops on Main Road. Decades of wind loosen roof tiles and leave gaps under the eaves that mice and rats find. Retirement villages with shared dining rooms and kitchens need regular cockroach checks. Many households have lived in the same place for a long time, so garages and storerooms tend to be full, which rodents appreciate.
The town sits on sandy ground on the valley floor that links False Bay to Noordhoek, with mountains on both sides. Winter brings rain and cold north-westers, while summer belongs to the South-Easter. The slopes and the Silvermine side give scorpions, spiders and rodents plenty of natural habitat right next to the houses.
How to tell you have a problem
- Fishmoths drop from the ceiling or come out of light fittings and cornices, a sign they are living in the roof space.
- Shed scales and skins collect in drawers, cupboards and bathroom corners.
- Irregular grazed patches or small holes appear on book covers, wallpaper or photographs.
- 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.
- 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.
Worth knowing
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.
Our process, step by step
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.
- Fix leaks under basins, around geysers and in the roof, since fishmoths need moisture.
- Store books, documents and photographs in sealed plastic boxes, not cardboard, especially in garages and storerooms.
- Avoid stacking old newspapers, magazines and cardboard boxes in cupboards for long periods.
- 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.
Moving books into sealed boxes and running a dehumidifier will help more than any spray from the shop. DIY sprays rarely reach the roof space or wall voids where the main population lives. If you are seeing them in several rooms or dropping from the ceiling, get the roof space treated professionally.
Fishmoth Control questions from Fish Hoek
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 treat retirement complexes in Fish Hoek?
Yes. We work with complexes on cockroach, rodent and ant control and can do disinfection of shared areas, choosing the least-toxic effective option first.
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 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.
Why do I find scorpions in my Fish Hoek garden?
Homes close to the mountain slopes are right on the edge of their natural habitat. Clearing rock piles and debris near the house and keeping doors sealed at the bottom helps a lot.
Do you come out to Fish Hoek for fishmoth control?
Yes. Fish Hoek is part of our regular South Peninsula route, along with Clovelly, Sun Valley, Noordhoek, Kalk Bay. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
