Nyanga is one of Cape Town's oldest townships and a major transport hub, with the busy junction and taxi ranks along Klipfontein Road. High density, busy trading areas and stormwater issues all affect pest pressure here.
Crawling insects in Nyanga: what we see
German cockroaches spread through shared walls and kitchens. Ants and crickets are common in sandy ground.
Homes range from older formal brick houses to backyard structures, hostels and informal dwellings built close together. Shared walls and tightly packed structures let rodents and cockroaches move easily between homes. Spaza shops, street traders and small food businesses operate from homes and containers. Gaps in walls and roofs, and floors at ground level, give pests easy access.
Nyanga sits on the flat, sandy Cape Flats, where winter rain can pool and flood low spots because the water table is high. The South-Easter blows sand and litter around in summer. Stormwater channels and open land nearby provide cover for rodents.
Signs to look for
- 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.
- 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.
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.
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.
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
- Store books, documents and photographs in sealed plastic boxes, not cardboard, especially in garages and storerooms.
- 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.
- Avoid stacking old newspapers, magazines and cardboard boxes in cupboards for long periods.
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.
Frequently asked questions
Can you treat a spaza shop in Nyanga for rats?
Yes. We set up bait stations and traps safely around stock and advise on sealing gaps, using the least-toxic effective method.
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.
Why are there more mosquitoes in Nyanga after winter rain?
Rain pools on the flat, sandy ground and in blocked drains, giving mosquitoes a place to breed. Clearing standing water near homes cuts their numbers.
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 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 you come out to Nyanga for fishmoth control?
Yes. Nyanga is part of our regular Cape Flats route, along with Gugulethu, Philippi, Manenberg, Hanover Park. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
