Electric City is a tight grid of family homes on the Blue Downs side of the Cape Flats, where most yards hold a main house, a backyard room and a washing line within a few metres of the boundary wall. A rat problem here is rarely one household's problem, so we usually end up talking to the neighbours as well.
Crawling insects around Electric City
German roaches hide behind fridges and in the warm motor housings of appliances, and they travel between attached units through gaps around pipes. Black ants and Argentine ants nest in the loose sand and come indoors after sweet things in summer.
The original houses are small brick units, and over the years most have grown sideways and backwards with extra rooms, carports and wendy houses. Every add-on leaves a join between old and new roof sheeting, and those joins are where roof rats and pigeons find their way in. Wendy houses sitting straight on sand give rats a dry floor to tunnel beneath. With walls almost touching, a cockroach colony in one kitchen does not take long to reach the next.
Norway rats burrowing under outbuildings are the call we take most, with mice a close second once it gets cold. Kitchens in older units often carry German cockroaches that have been there through several tenants. In summer it turns to fleas, house flies at the bins and ants marching across the stoep.
What gives them away
- Yellowish stains or tiny pepper-like droppings are left on paper and shelves.
- Wallpaper is lifting or damaged along the edges where the glue has been eaten.
- 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.
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.
From the technician
Landlords with older rental properties often get fishmoth complaints from tenants. A roof void treatment and better ventilation in the bathroom usually solves it for the long term.
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.
- 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.
- Fix leaks under basins, around geysers and in the roof, since fishmoths need moisture.
- 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.
Fishmoth Control questions from Electric City
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 Electric City for fishmoth control?
Yes. Electric City is part of our regular Cape Flats route, along with Kuils River, Delft, Belhar. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
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 rats keep coming back to my Electric City yard after I bait?
Usually because the neighbouring yards are untreated, so new rats move into the space yours left. Treating a few adjoining homes at once breaks that cycle.
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.
Is it rats or mice in my ceiling in Electric City?
Rat droppings are about the size of a raisin and mouse droppings look like grains of rice. WhatsApp us a photo and we will tell you which you are dealing with.
