Steenberg covers two quite different places: the busy residential area near Retreat and Lavender Hill, and the wine estate and golf course on the mountain side. We work across both, and the pest problems differ a lot between them.
The local picture in Steenberg
German cockroaches spread between closely built homes, while scorpions and rain spiders appear on the mountain side. Ants are everywhere in summer.
Near the railway and Steenberg station, homes are mainly older council houses, semis and flats, often with backyard rooms. Closer to the mountain, the estate side has newer, larger homes in security developments. Dense housing makes it easy for rodents and cockroaches to spread, while large estate homes deal more with mountain-edge pests. Shops and taxi ranks along the main roads add food sources.
Rats and German cockroaches dominate in the denser areas, while mice, ants and scorpions are more typical on the estate side. Mosquitoes and fleas are common in summer.
Worth knowing
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.
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.
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.
- Yellowish stains or tiny pepper-like droppings are left on paper and shelves.
- Shed scales and skins collect in drawers, cupboards and bathroom corners.
- 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.
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.
- 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
- Store books, documents and photographs in sealed plastic boxes, not cardboard, especially in garages and storerooms.
- 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.
- Fix leaks under basins, around geysers and in the roof, since fishmoths need moisture.
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.
Questions we get asked in Steenberg
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 Steenberg for fishmoth control?
Yes. Steenberg is part of our regular Southern Suburbs route, along with Retreat, Lavender Hill, Tokai, Kirstenhof. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
Do you service both sides of Steenberg?
Yes, we cover the residential area near Retreat and the estates on the mountain side. Treatments are tailored to each type of home.
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.
Why do I find scorpions in my Steenberg estate home?
Homes near the mountain border fynbos and rocky ground where scorpions live. Sealing gaps under doors and clearing rock piles near the house helps.
