West Beach is the strip between Table View and Bloubergstrand, built on dune land right behind the beach. Wind, sand and salt rule here, and most of the pest issues we see are shaped by being a stone's throw from the sea.
West Beach: what drives crawling insects here
Black ants nest in the sand under paving and along walls, and fishmoths thrive in the damp sea air. Spiders and crickets come in from the dunes.
Homes are mostly modern freestanding houses and townhouses, many with flat roofs, big windows and paved courtyards. There are also apartment complexes and a few holiday homes that stand empty for parts of the year. Courtyards and enclosed patios trap blown sand and leaf litter, giving ants and other crawlers a place to settle.
A note from the field
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.
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 gives them away
- 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.
- Yellowish stains or tiny pepper-like droppings are left on paper and shelves.
- 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.
- Irregular grazed patches or small holes appear on book covers, wallpaper or photographs.
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.
- Confirm and identify
We confirm it is fishmoths and not booklice or another small insect, which need different handling.
- Find where they live
The technician checks the roof space, cupboards, bookshelves, bathrooms and stored boxes for the main population.
- Check for damp
We look for leaks, poor ventilation and damp walls, because fishmoths follow moisture.
- Treat voids and cracks
Dust goes into the roof space and voids, and residual products into cracks, skirtings and cupboard corners.
- Report and remedial advice
You get a post-treatment report covering what we treated and what to change in storage and ventilation.
Keeping them out afterwards
- 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.
- 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.
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 West Beach
Do you come out to West Beach for fishmoth control?
Yes. West Beach is part of our regular Blaauwberg & West Coast route, along with Table View, Bloubergstrand, Parklands. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
Can you stop gulls landing on my West Beach roof?
Yes. Bird wire, spikes and solar panel guards make the roof much less comfortable for gulls and pigeons.
Why are ants so bad in West Beach homes?
The suburb sits on dune sand, which makes perfect nesting ground right under paving and along walls. Baiting the colony at the source gives better results than spraying the trails.
How long does a fishmoth treatment last?
Our treatments carry a minimum 3-month guarantee. Fixing damp and changing storage habits makes the result last much longer.
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.
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.
