Firgrove is a small, quiet spot on the Somerset West side of the Helderberg, with a country feel and a lot of open land around it. People here mostly call us about mice from the fields, flies around animals and wasps in the sheds.
The local picture in Firgrove
Argentine ants, rain spiders and scorpions are common in homes close to open land, and fishmoths like the older houses.
You get a mix of older village houses, smallholdings with sheds and stables, and some newer homes on larger plots. Smallholdings often keep animal feed, poultry and compost, which is a standing invitation to rodents. Older homes and outbuildings with exposed timber are worth checking for borer. Sheds full of stored equipment make perfect quiet nesting spots.
Field mice and rats looking for shelter are the main call, especially after harvest and in winter. Flies around livestock and paper wasps in sheds follow in summer, and homes on the edge of open land see more spiders and the odd scorpion.
A note from the field
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.
Signs to look for
- Shed scales and skins collect in drawers, cupboards and bathroom corners.
- Fishmoths drop from the ceiling or come out of light fittings and cornices, a sign they are living in the roof space.
- 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.
- Clothing, curtains or linen made from cotton, linen or silk have small holes or thinned patches.
What happens when we come out
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.
Stopping a repeat visit
- 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.
- Improve ventilation in bathrooms and laundries with an extractor fan or by keeping a window open after showers.
- Avoid stacking old newspapers, magazines and cardboard boxes in cupboards for long periods.
- Vacuum regularly inside cupboards, along skirting boards and behind furniture to remove eggs and food sources.
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 Firgrove
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 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.
Do you come out to Firgrove for fishmoth control?
Yes. Firgrove is part of our regular Helderberg route, along with Somerset West, Macassar, Strand, Helderberg. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
Why are there suddenly mice in my Firgrove house in autumn?
Cooler weather and work on the surrounding fields push mice toward warm, sheltered buildings. Sealing gaps under doors and around pipes early in autumn keeps most of them out.
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 you service smallholdings and outbuildings in Firgrove?
Yes. We cover the house, sheds, stables and feed stores, and we plan bait placement so it stays out of reach of pets and livestock.
