Heathfield is a quiet, family suburb sitting between Diep River and Retreat, with the railway on one side and Main Road businesses nearby. The calls here are pretty classic Southern Suburbs fare: rats in the roof, ants in the kitchen and a few fleas each summer.
Crawling insects in Heathfield: what we see
Argentine ants trail through the kitchen in summer, and American cockroaches come up from drains. Crickets and the occasional rain spider are common in garden homes.
The housing is mostly free-standing family homes and semi-detached houses from the mid-twentieth century, with tiled or corrugated roofs and modest gardens. There are also some townhouse complexes and a few blocks of flats. Older timber roof trusses can host borer, and the gaps where extensions join the original house are a favourite entry point for mice.
It lies on the flatter ground below the Constantiaberg and Tokai side, with the railway corridor running through. Winter brings proper rain and damp, and stormwater channels and the nearby vlei systems towards Zandvlei hold water. Gardens with lawns and compost heaps keep crickets and ants busy in summer.
Rats and mice, especially in winter when they come inside for warmth, are top of the list. Argentine ants in kitchens, fleas from pets and mosquitoes after rain round it out. Cockroaches are more of an issue near the Main Road shops and takeaways.
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.
What gives them away
- Shed scales and skins collect in drawers, cupboards and bathroom corners.
- Silvery, fast-moving insects are seen when you lift boxes, books or linen.
- 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.
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.

Prevention that actually works
- 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.
- 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.
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
How soon can you come out to Heathfield?
Our average turnaround is about 48 hours, although it varies with the season. If it is urgent, call our 24-hour emergency line for advice and to book.
Do rats in Heathfield come from the railway line?
Often, yes. The railway reserve gives rats cover and food, and homes backing onto it see more activity, so we focus bait stations along the boundary wall.
Do you come out to Heathfield for fishmoth control?
Yes. Heathfield is part of our regular Southern Suburbs route, along with Diep River, Retreat, Kirstenhof, Bergvliet. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
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.
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.
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.
