Grassy Park is wedged between Zeekoevlei and Rondevlei, with the Lotus River canal cutting through nearby, so standing water shapes life here more than in most Cape Flats suburbs. Summer evenings mean mosquitoes, and the canal banks mean rats, and between those two we stay busy.
Grassy Park: what drives crawling insects here
German roaches turn up in kitchens and in the shops along the main roads. Ants nest in the sandy soil, and crickets and fishmoths like damp outbuildings.
Most homes are freestanding brick houses on decent-sized plots, many with garages turned into rooms, carports and backyard flats. Prince George Drive and Victoria Road carry a long line of shops, takeaways and small businesses with storerooms behind them. Older homes have wooden floors in places and roof spaces that rats can reach from overhanging trees. Where plots back onto vlei edges or open land, rodents and insects arrive from the garden side rather than the street.
Zeekoevlei is one of the largest freshwater lakes on the Cape Flats, and Rondevlei next door is a nature reserve with reedbeds and, famously, hippos. The water table sits high in this sandy ground, so winter rain lingers in low yards and stormwater drains. Reeds and still water along both vleis and the canal are prime mosquito habitat once it warms up.
Signs to look for
- Clothing, curtains or linen made from cotton, linen or silk have small holes or thinned patches.
- Yellowish stains or tiny pepper-like droppings are left on paper and shelves.
- 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.
- Irregular grazed patches or small holes appear on book covers, wallpaper or photographs.
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.
Worth knowing
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.
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.
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.

Prevention that actually works
- 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.
- Fix leaks under basins, around geysers and in the roof, since fishmoths need moisture.
- Seal cracks around skirting boards, cornices and built-in cupboards where they hide and lay eggs.
- 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.
Moving books into sealed boxes and running a dehumidifier will help more than any spray from the shop. DIY sprays rarely reach the roof space or wall voids where the main population lives. If you are seeing them in several rooms or dropping from the ceiling, get the roof space treated professionally.
Fishmoth Control questions from Grassy Park
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.
Do you come out to Grassy Park for fishmoth control?
Yes. Grassy Park is part of our regular Cape Flats route, along with Lotus River, Pelican Park, Lavender Hill, Retreat. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
Why are the mosquitoes so bad in Grassy Park?
Zeekoevlei, Rondevlei and the Lotus River canal give them a huge amount of breeding water close to homes. Removing standing water at home and treating resting areas around the house makes a noticeable difference.
Do rats come from the canal into Grassy Park homes?
Yes, the canal and vlei edges are major rat habitat, and they move into gardens along walls and fences. Bait stations along your boundary help keep them out.
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 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.
