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.
Crawling insects around 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.
Farmland and vineyards surround the area, with the Helderberg and the Hottentots Holland mountains on the skyline. The South-Easter blows strongly through summer, and winters are wet and chilly. When fields are ploughed or harvested, the rodents living in them look for new homes.
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.
Something most people miss
Daddy longlegs are often said to be the most venomous spider in the world with fangs too weak to bite. It is a myth. They are harmless to people and actually prey on other spiders, so a few in the corners of the house are not worth losing sleep over.
Tell-tale signs
- Egg sacs, often round and papery or spiky in the case of the brown button spider, are stuck to brickwork or furniture.
- Untidy, tangled webs show up under outdoor chairs, in the meter box or around the pool pump.
- Outside lights draw a cloud of moths and midges each night with webs built right around them.
- Cast skins and dead insects collect along skirting boards and in the backs of cupboards.
How we handle spider control in Firgrove
We start by identifying the species, because a rain spider on the wall and a nest of button spiders by the jungle gym call for very different responses. Webs and egg sacs are removed by hand or vacuum first, which takes out a surprising amount of the next generation. We then apply a residual spray or a fine insecticide dust into the places spiders actually live: roof voids, behind fitted units, wall cavities, garages, eaves and window reveals, keeping it away from where children and pets play. Where insects are drawing the spiders in, we treat or advise on that food source too, because spiders follow their prey. Finally we point out gaps around doors, vents and pipes that need sealing.

Prevention that actually works
- Shake out shoes, gardening gloves and clothes that have been left on the floor or in the garage before you put them on.
- Keep stacked wood, bricks and old pots away from the house walls, because these are prime spots for button spiders.
- Brush down webs regularly and vacuum the corners and the backs of cupboards, which gets rid of egg sacs before they hatch.
- Fit fine mesh to vents and seal the gaps around pipes and under doors with sealant or brush strips.
- Swap white outdoor bulbs for warm yellow or LED ones so fewer insects gather, which means fewer spiders setting up around your doors.
How much will it cost?
The cost depends mainly on the size of the property and how many outbuildings, garages and roof spaces need treatment. A house with a heavy insect problem feeding the spiders takes more work than one with a few webs in the corners. We give a free quote after a quick look or a WhatsApp photo, and contract clients get spiders covered as part of their routine visits.
Spider activity climbs from late spring and peaks in the hot, dry months from January to March, which is exactly when rain spiders come indoors and people start to notice them. Button spiders are most visible in summer around gardens and pools. In the wet winter months many spiders retreat into roof spaces and garages, so a treatment then catches them where they shelter.
Spider Control questions from Firgrove
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.
Will the treatment harm my pets?
We treat cracks, voids and roof spaces rather than open floors, and we ask that pets are kept out until surfaces are dry. We will explain any specific precautions on the day.
Is the rain spider in my house dangerous?
Not really. Rain spiders are big and fast but rarely bite, and the bite is painful rather than dangerous; the kindest option is to catch it under a container and put it outside.
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.
How do I know if I have violin spiders?
They are light brown with long legs and a darker violin-shaped mark on the front of the body, and they hide in undisturbed storerooms, cupboards and garages. Send us a clear photo on WhatsApp and we will tell you what it is.
Do you come out to Firgrove for spider 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.
