Thornton is a small, leafy suburb squeezed between Pinelands, Epping Industria and Goodwood. Being right next to an industrial area means rodents are never far away, even on the quietest residential streets.
Crawling insects in Thornton: what we see
American cockroaches come from drains and the industrial side, while Argentine ants trail across gardens and into kitchens. Fishmoths are common in older built-in cupboards.
The homes are mainly freestanding houses from the mid-twentieth century, many with established gardens, mature trees and outbuildings. Some have older timber roof structures and wooden floors. On the edges, warehouses and factories in Epping and Ndabeni bring a constant source of pests that spill over into residential gardens.
The suburb is fairly flat, with Cape Flats sand underfoot and big trees that shade gardens and roofs. Winter rain soaks the ground and pushes rodents and ants indoors. The railway lines and open strips along them act as green corridors for rats.
Tell-tale signs
- Yellowish stains or tiny pepper-like droppings are left on paper and shelves.
- Silvery, fast-moving insects are seen when you lift boxes, books or linen.
- Clothing, curtains or linen made from cotton, linen or silk have small holes or thinned patches.
- Shed scales and skins collect in drawers, cupboards and bathroom corners.
Something most people miss
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.
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.
- Confirm and identify
We confirm it is fishmoths and not booklice or another small insect, which need different handling.
- Find where they live
The technician checks the roof space, cupboards, bookshelves, bathrooms and stored boxes for the main population.
- Check for damp
We look for leaks, poor ventilation and damp walls, because fishmoths follow moisture.
- Treat voids and cracks
Dust goes into the roof space and voids, and residual products into cracks, skirtings and cupboard corners.
- Report and remedial advice
You get a post-treatment report covering what we treated and what to change in storage and ventilation.
Keeping them out afterwards
- 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.
- Avoid stacking old newspapers, magazines and cardboard boxes in cupboards for long periods.
- 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.
Pricing, honestly
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.
Questions we get asked in Thornton
Do the rats in Thornton come from Epping Industria?
Often, yes. The warehouses and the railway reserve support large rat populations, and they move into gardens in winter, so blocking roof and drain access on your home is important.
Do you come out to Thornton for fishmoth control?
Yes. Thornton is part of our regular Northern Suburbs route, along with Pinelands, Epping, Goodwood, Ndabeni. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
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.
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.
Can you remove a squirrel nesting in my Thornton ceiling?
Yes. We find the entry point, deal with the squirrel and then seal the gap so it cannot come back.
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.
