Bishopscourt is a very green suburb of large homes, ambassadors' residences and old trees right beside Kirstenbosch. Pest work here is often about big properties with outbuildings, staff quarters, pools and heavy garden growth, rather than anything to do with density.
The local picture in Bishopscourt
Argentine ants come in from big gardens, and rain spiders and baboon spiders turn up near the mountain. Fishmoths enjoy libraries and older cupboards.
Homes are large, many on double plots, with thatched lapas, timber decks, wine cellars and staff cottages. All that space means plenty of ceilings, outbuildings and garages for rodents to hide in. Thatch and exposed timber also bring timber pest concerns.
Bishopscourt sits on the slopes below Table Mountain, with Kirstenbosch and the national park right next door. The Liesbeek River starts nearby, and winter rain keeps everything wet and lush. Big oaks, pines and fruit trees feed rodents and squirrels.
Roof rats and grey squirrels in ceilings are common, and mole rats tunnel through lawns. Wasps nest in eaves and hedges, and ants trail in from the gardens. Timber borer and thatch pests are a real consideration on these properties.
Tell-tale signs
- Clothing, curtains or linen made from cotton, linen or silk have small holes or thinned patches.
- Irregular grazed patches or small holes appear on book covers, wallpaper or photographs.
- Silvery, fast-moving insects are seen when you lift boxes, books or linen.
- Wallpaper is lifting or damaged along the edges where the glue has been eaten.
- Yellowish stains or tiny pepper-like droppings are left on paper and shelves.
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 we handle fishmoth control in Bishopscourt
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.
- 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.
- 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.
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.
Fishmoth Control questions from Bishopscourt
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 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.
Should I worry about borer in my Bishopscourt thatch lapa?
It is worth checking, because thatch and timber in shady, damp spots can attract wood-boring beetles. A yearly inspection catches problems early and keeps the structure sound.
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 the trees near Kirstenbosch bring squirrels into Bishopscourt roofs?
Yes, grey squirrels and roof rats use the tall trees as highways onto roofs. We trim access routes, seal gaps and treat roofs where needed.
Do you come out to Bishopscourt for fishmoth control?
Yes. Bishopscourt is part of our regular Southern Suburbs route, along with Newlands, Claremont, Constantia, Kenilworth. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
