Plattekloof sits high on the Tygerberg Hills above the N1, so most of our calls here are about pests coming in from the hillside rather than from neighbours. Big gardens, open veld on the ridge and a busy office node lower down give it a mix of household and commercial work.
Crawling insects in Plattekloof: what we see
Brown house ants and black garden ants are steady in summer, and the rocky gardens give scorpions and rain spiders places to hide. Large kitchens and pantries can carry German cockroaches if they get in with deliveries.
Most homes are large, freestanding family houses from the 1970s onwards, with tiled roofs, double garages and a fair number of pools. There are also townhouse complexes and the office parks off Plattekloof Road. The bigger houses have plenty of roof void and garage storage, which is where rodents and cockroaches settle in unnoticed. Office blocks and their kitchens need regular scheduled checks rather than once-off sprays.
The suburb runs up the slopes of the Tygerberg Hills, with Tygerberg Nature Reserve and undeveloped veld not far off. Winters are wet and windy, summers hot and dry, and the ridge catches the full force of the South-Easter. That mix pushes insects and rodents indoors when the first cold fronts arrive.
Mice and roof rats moving in from the veld edge each autumn are the main complaint. In summer it shifts to ants, wasps around the eaves and the odd scorpion in garden walls. Office kitchens and canteens in the business parks mostly need German cockroach control.
Tell-tale signs
- 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.
- 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.
- 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.
A note from the field
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 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.
How we handle fishmoth control in Plattekloof
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
- 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.
- Store books, documents and photographs in sealed plastic boxes, not cardboard, especially in garages and storerooms.
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.
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.
Frequently asked questions
Do you come out to Plattekloof for fishmoth control?
Yes. Plattekloof is part of our regular Northern Suburbs route, along with Panorama, Parow, Monte Vista, Goodwood. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
Can you service the office parks in Plattekloof after hours?
Yes, after-hours and weekend visits can be arranged on request so staff are not disturbed. We leave a post-treatment report so building managers have a record.
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.
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 do I get more mice in Plattekloof when it starts raining?
The first cold fronts flush mice out of the veld on the hill and they head for warm roofs and garages. Proofing entry points in April and May usually stops the seasonal wave.
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.
