Muizenberg is surf, sand, old seaside buildings and Zandvlei all squeezed between the mountain and False Bay. Damp, salty air and the vlei shape most of the pest calls we get here.
The local picture in Muizenberg
Fishmoths and silverfish are very common in the damp sea air, and American cockroaches come up through old drains. Ants trail indoors when the South-Easter dries the garden out.
Along the beachfront and Main Road there are Edwardian and art deco buildings, old holiday villas and blocks of flats, many with timber floors and sash windows. Up the slope toward the mountain the houses get bigger and older, some with wooden roof structures that have seen a century of sea air. Guest houses and backpackers add constant turnover. Older buildings with cracked plaster and gaps under doors let in sand, damp and insects.
Zandvlei estuary sits on the eastern edge, the Muizenberg mountain and Silvermine slopes rise behind the village, and the long False Bay beach runs east toward Strandfontein. The South-Easter blows hard in summer, piling sand against walls and drying everything out. Winter brings rain and damp, which suits fishmoths and wood borer in old timber.
Mosquitoes from Zandvlei in late summer, fishmoths in damp homes and rodents around the Main Road shops are the regular issues. Bed bugs and fleas come up in guest houses and rentals. Wood borer is a real concern in the older buildings.
How to tell you have a problem
- Shed scales and skins collect in drawers, cupboards and bathroom corners.
- Wallpaper is lifting or damaged along the edges where the glue has been eaten.
- Irregular grazed patches or small holes appear on book covers, wallpaper or photographs.
- 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.
- Clothing, curtains or linen made from cotton, linen or silk have small holes or thinned patches.
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
Fishmoths can live for several years and can survive months without food. That is why a single wipe-down does not work and why treatments that keep working in cracks are so useful.
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.

Keeping them out afterwards
- Avoid stacking old newspapers, magazines and cardboard boxes in cupboards for long periods.
- Store books, documents and photographs in sealed plastic boxes, not cardboard, especially in garages and storerooms.
- Seal cracks around skirting boards, cornices and built-in cupboards where they hide and lay eggs.
- Vacuum regularly inside cupboards, along skirting boards and behind furniture to remove eggs and food sources.
- Fix leaks under basins, around geysers and in the roof, since fishmoths need moisture.
Pricing, honestly
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 Muizenberg
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.
Do old Muizenberg houses need a beetle certificate before sale?
Most buyers and banks in the Western Cape ask for one, and older homes with original timbers here often show borer activity. We inspect the roof timbers and floors and report what we find.
Why are there so many mosquitoes in Muizenberg near Zandvlei?
The reed beds and still water around Zandvlei are ideal breeding sites, and they peak on warm, windless evenings in late summer. Removing standing water in your own garden and screening bedroom windows helps a lot.
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 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.
Do you come out to Muizenberg for fishmoth control?
Yes. Muizenberg is part of our regular South Peninsula route, along with St James, Lakeside, Marina da Gama, Kalk Bay. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
