Kenilworth is built around the racecourse, with grand old homes on plane-tree avenues on one side and blocks of flats crowding toward Main Road and the railway on the other. That mix of old timber, big trees and dense flats keeps us busy with squirrels, rats and roaches in roughly equal measure.
Kenilworth: what drives crawling insects here
German cockroaches travel between flats through shared plumbing and refuse chutes, so whole-block treatment works best. Argentine ants trail in from garden beds in summer, and fishmoths like old built-in cupboards.
Victorian and Edwardian houses with high ceilings, suspended timber floors and deep roof voids sit alongside 1960s and 70s blocks of flats, townhouse complexes and retirement villages. The old houses give rodents space under floors and in roofs, while the flats share plumbing stacks and refuse rooms that let German cockroaches move from unit to unit. Student and rental flats near the railway turn over regularly, which can introduce bed bugs.
The Kenilworth Racecourse Conservation Area protects one of the last patches of Cape Flats sand fynbos, home to small mammals, frogs and a wetland that fills in winter. Avenues of plane trees and oaks shade many streets, and the Southern line railway runs along the western edge past Kenilworth station. Winter brings heavy rain off the mountain, damp underfloor spaces and rodents moving indoors.
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.
- Clothing, curtains or linen made from cotton, linen or silk have small holes or thinned patches.
- 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 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.
A note from the field
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.
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.

Keeping them out afterwards
- 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.
- Fix leaks under basins, around geysers and in the roof, since fishmoths need moisture.
- Avoid stacking old newspapers, magazines and cardboard boxes in cupboards for long periods.
- Store books, documents and photographs in sealed plastic boxes, not cardboard, especially in garages and storerooms.
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 Kenilworth
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.
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.
Does living next to the Kenilworth racecourse mean more mice?
Often, yes, especially once it turns cold and wet. Homes on the boundary do well with sealed door sweeps and a few bait stations along the fence line.
Are the squirrels in my Kenilworth ceiling coming from the street trees?
Almost certainly. The plane trees and oaks give grey squirrels a direct route onto roofs, so cutting back overhanging branches and sealing chewed fascias is the first step.
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.
Do you come out to Kenilworth for fishmoth control?
Yes. Kenilworth is part of our regular Southern Suburbs route, along with Claremont, Harfield Village, Wynberg, Kenwyn. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
