Clovelly is a small pocket squeezed between the mountain and the railway line on the way into Fish Hoek. Most calls here come from homes that back onto fynbos or the golf course, so a good share of what turns up indoors has walked in from the veld.
Clovelly: what drives crawling insects here
Argentine ants are the main nuisance, with fishmoths in older built-in cupboards. Homes backing onto fynbos sometimes find a scorpion or a rain spider in the garage or in a shoe left outside.
Housing is mostly freestanding family homes, many stepped into the slope with retaining walls, split levels and sub-floor voids underneath. Older houses often still have timber floors and wooden window frames that have taken decades of salty air. Those voids under suspended floors and the gaps around old garage doors are exactly where mice settle in for winter. A few flats and townhouses closer to Main Road add the usual shared-bin and shared-roof issues.
Rodents moving down off the mountain edge in the cooler months are the classic Clovelly call. Argentine ants come a close second, especially in January and February when they trail along skirtings to the kitchen sink. Homes near the river mouth get more mosquitoes than you'd expect, and paper wasps like the sunny eaves on the upper slope.
From the technician
A frequent mistake is spraying the cupboard and leaving everything else as it was. If the cardboard boxes and damp corners stay, the fishmoths will be back within a few months.
Fishmoths are harmless to children and pets, which means you can take your time and choose a gentle, targeted treatment rather than anything heavy-handed.
Tell-tale signs
- Wallpaper is lifting or damaged along the edges where the glue has been eaten.
- 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 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.
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.
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.

Prevention that actually works
- 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.
- 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.
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.
Fishmoth Control questions from Clovelly
Why does my Clovelly house get more mosquitoes than friends in Fish Hoek?
Homes near the low ground where the Silvermine River meets the sea are close to standing water after rain. Clearing gutters and pot saucers helps, and we can treat resting spots in the garden if it is bad.
Do rats in Clovelly really come down from the mountain?
Some do, especially in winter when the veld is cold and wet. Many are already living in compost heaps and under decks nearby, so we check the garden as well as the ceiling and deal with both.
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 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 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 you come out to Clovelly for fishmoth control?
Yes. Clovelly is part of our regular South Peninsula route, along with Fish Hoek, Kalk Bay, St James, Sun Valley. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
