Higgovale sits high on the slopes below Table Mountain and Lion's Head, with Kloof Nek just above. The houses are big and often right up against the mountain, so we deal with as many visitors from the slopes as we do from the street.
Crawling insects around Higgovale
Scorpions and rain spiders turn up in lower-level rooms and garages near the slope. Argentine ants trail inside in summer, and fishmoths like the damp lower floors.
Homes here are mostly large, architect-designed houses on steep plots with retaining walls, pools and multiple levels. There are some older homes with timber roofs and floors, and many newer ones with flat concrete roofs and glass. Split levels, garages dug into the slope and gaps around wooden decks give rodents plenty of hidden spaces to nest.
Higgovale backs onto Table Mountain National Park, with fynbos, pine and gum trees above and the Kloof Nek area close by. Winter rain runs down the slopes, and the mountain stays damp and cool for longer than the City Bowl below. The mountain edge brings scorpions, spiders, field mice and the occasional dassie or snake into gardens.
What gives them away
- Irregular grazed patches or small holes appear on book covers, wallpaper or photographs.
- Shed scales and skins collect in drawers, cupboards and bathroom corners.
- 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.
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
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.
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.
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
- 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.
- 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.
- 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.
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.
Frequently asked questions
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.
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 Higgovale for fishmoth control?
Yes. Higgovale is part of our regular City Bowl & Atlantic Seaboard route, along with Tamboerskloof, Oranjezicht, Gardens, Camps Bay. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
Do mice come down from Table Mountain into Higgovale homes?
Yes, especially in the cold, wet months. We look for entry points along the slope side of the house, garage doors and roof edges, then set up bait and seal the gaps.
Are the scorpions in Higgovale dangerous?
Most of the ones found in mountain-side gardens have big pincers and thin tails, and their sting is painful rather than dangerous, but anyone stung should still get medical advice. We can treat the perimeter and lower rooms to reduce how many come inside.
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.
