Lavender Hill is a close-knit area of council flats and family homes between Retreat, Steenberg and Grassy Park. Many people live in a small space here, so we focus on treatments that are safe around children and that a whole block can do together.
Lavender Hill: what drives crawling insects here
German cockroaches move through the shared ducts and walls between flats, so one unit's infestation spreads quickly. Ants are a summer pest in kitchens.
Most homes are in three-storey council flats and maisonettes, with free-standing houses and backyard structures in between. Flats share stairwells, roof spaces and service ducts, so cockroaches and rodents travel between units easily. Ground-floor flats near bin areas tend to take the brunt of rat activity.
The area sits on low-lying Cape Flats sand not far from Zeekoevlei and the vleis around Vrygrond. In winter, rain can pool on open fields and in poorly drained courtyards for days. The summer South-Easter blows sand and litter across open ground, building up piles where rodents hide.
Tell-tale signs
- 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.
- 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.
Worth knowing
Many people think fishmoths only eat paper. They also go after the glue in wallpaper and book bindings, starch in fabrics, and even dried food crumbs and dead insects in cupboards.
What happens when we come out
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.

Keeping them out afterwards
- Improve ventilation in bathrooms and laundries with an extractor fan or by keeping a window open after showers.
- 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.
- 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.
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 Lavender Hill
Do you come out to Lavender Hill for fishmoth control?
Yes. Lavender Hill is part of our regular Cape Flats route, along with Retreat, Steenberg, Grassy Park, Lotus River. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
Are your treatments safe in a small flat with children?
We use the least-toxic effective option first and tell you exactly how long to keep children and pets out of treated areas. Most treatments are odourless and you can go back in the same day.
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.
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.
Can you treat just my flat if the neighbours have cockroaches too?
We can, and it will help, but cockroaches will come back through the shared walls and ducts. Treating the neighbouring flats at the same time gives much longer-lasting results.
