Kalksteenfontein is small enough that most people know their neighbours, and that helps, because rats here are a shared problem rather than a private one. Give us a block of five or six houses that agree to treat together and we can make a real dent.
Kalksteenfontein: what drives crawling insects here
German cockroaches hide behind stoves and fridge motors, then spread along shared walls. Black ants nest in sandy yards and come inside in the heat.
It is mostly compact council-built homes in rows and pairs, with wendy houses and brick rooms added in the backyards over the years. Roof lines often run unbroken across several homes, which gives mice a private corridor above the ceilings. The backyard rooms, with their timber floors sitting on sand, are where we find rat burrows most often.
Expect rats first, then German cockroaches in kitchens. Summer brings flies and fleas, and bed bugs come up where furniture changes hands.
Tell-tale signs
- Wallpaper is lifting or damaged along the edges where the glue has been eaten.
- 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.
- Irregular grazed patches or small holes appear on book covers, wallpaper or photographs.
- Silvery, fast-moving insects are seen when you lift boxes, books or linen.
- 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
When a technician deals with fishmoths, the first place they look is up. The roof space is often where the main population lives, out of sight, especially with the grey silverfish common in Cape Town.
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.
How we handle fishmoth control in Kalksteenfontein
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
- Store books, documents and photographs in sealed plastic boxes, not cardboard, especially in garages and storerooms.
- 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.
- Avoid stacking old newspapers, magazines and cardboard boxes in cupboards for long periods.
- Seal cracks around skirting boards, cornices and built-in cupboards where they hide and lay eggs.
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.
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.
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.
Why do rats keep coming back in Kalksteenfontein after treatment?
Rats move between homes and open ground, so if only one yard is treated, new rats move in. Treating several homes together and removing food sources gives better long-term results.
Can you treat a backyard wendy house for cockroaches?
Yes. We use gel baits and targeted treatments that work well in small spaces, and we tell you when it is safe to use the room again.
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 come out to Kalksteenfontein for fishmoth control?
Yes. Kalksteenfontein is part of our regular Cape Flats route, along with Bishop Lavis, Elsies River, Bonteheuwel, Valhalla Park. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
