Kenwyn is a small, settled suburb tucked in east of Kenilworth, the kind of place where people have lived in the same house for decades. That is good news for spotting problems early, and a lot of what we see here is slow-building stuff: mice in a garage that nobody uses, borer in an old cupboard, ants that come back every December.
Crawling insects in Kenwyn: what we see
Argentine ants make long trails into kitchens in hot weather, and fishmoths chew through paper and old photos stored in cupboards. Crickets get noisy in the garden in late summer.
Homes are mostly solid mid-century bungalows and semi-detached houses with tiled roofs, garages and decent-sized gardens, plus a handful of townhouse complexes. Plenty have flat-roofed extensions added later, and the join between old and new roof is where water and mice both tend to get in. Garages and outside rooms full of stored boxes are a common nesting spot.
Mice in garages and ceilings, Argentine ants and fishmoths are the steady regulars. Roof rats visit when fruit trees are heavy, and fleas follow pets in summer. Cockroaches are less of an issue than in denser areas, but American cockroaches do come up through older drains.
Tell-tale signs
- Clothing, curtains or linen made from cotton, linen or silk have small holes or thinned patches.
- 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.
- 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.
- Yellowish stains or tiny pepper-like droppings are left on paper and shelves.
A note from the field
Fishmoths are harmless to children and pets, which means you can take your time and choose a gentle, targeted treatment rather than anything heavy-handed.
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 the treatment works
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
- 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.
- Vacuum regularly inside cupboards, along skirting boards and behind furniture to remove eggs and food sources.
- 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.
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.
Frequently asked questions
We are selling our Kenwyn house. Do we need a beetle certificate?
Most sale agreements and banks in the Western Cape require one. We can inspect the roof and accessible timber and provide the report you need.
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 the ants come back to my Kenwyn kitchen every summer?
Argentine ant colonies live in the garden and send foragers inside when it gets hot and dry. Baiting the trails outside, rather than spraying the ones you see, knocks the whole colony back.
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 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 Kenwyn for fishmoth control?
Yes. Kenwyn is part of our regular Southern Suburbs route, along with Kenilworth, Harfield Village, Lansdowne, Claremont. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
