Newlands sits on the wet side of Table Mountain under big oaks and pines, and that moisture drives a lot of what we see here. Squirrels in roofs, fishmoths in cupboards and borer in old timber are bread and butter for us in this suburb.
Crawling insects in Newlands: what we see
Fishmoths, silverfish and woodlice thrive in shaded, damp houses. Ants trail inside after rain, and rain spiders wander in during summer.
There is a real mix: large older homes on generous plots, Newlands Village cottages, newer cluster homes and apartment blocks closer to Main Road and the sports grounds. Many of the older houses have timber floors, wooden ceilings and roof spaces that stay cool and damp. Leafy gardens and big trees overhang roofs, giving squirrels and rats a direct route in. Some homes have thatch outbuildings or pergolas.
Newlands is one of the wettest suburbs in Cape Town, with Newlands Forest and the Table Mountain National Park slopes right above it and the Liesbeek running through. Winter rain is heavy and long, and many properties stay shaded and damp for months. Mountain streams and forest edges bring wildlife close to gardens.
Grey squirrels and rats in roofs are the top complaint, especially in autumn and winter. Fishmoths, booklice and clothes moths love the damp. Wood borer in old timbers and wasps in summer complete the picture.
Something most people miss
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.
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.
Signs to look for
- Wallpaper is lifting or damaged along the edges where the glue has been eaten.
- 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.
- Irregular grazed patches or small holes appear on book covers, wallpaper or photographs.
- Fishmoths drop from the ceiling or come out of light fittings and cornices, a sign they are living in the roof space.
- Silvery, fast-moving insects are seen when you lift boxes, books or linen.
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.
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.

Stopping a repeat visit
- Seal cracks around skirting boards, cornices and built-in cupboards where they hide and lay eggs.
- 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.
- 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.
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 Newlands
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.
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.
How do I get squirrels out of my Newlands roof?
We find the entry points, make sure the squirrels are out, and then seal the gaps with mesh so they cannot return. Trimming nearby branches is part of keeping them out.
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.
Do you come out to Newlands for fishmoth control?
Yes. Newlands is part of our regular Southern Suburbs route, along with Claremont, Rondebosch, Bishopscourt, Harfield Village. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
Why are fishmoths so bad in Newlands houses?
Newlands is one of Cape Town's wettest suburbs, and fishmoths feed on starch and thrive in damp, shaded rooms. Reducing humidity and treating cupboards and skirtings brings them under control.
