Glencairn is a quiet strip of False Bay coast where the Simon's Town train runs right past the beach and the houses step up the slopes toward the mountain. Behind the sand sits a reedy wetland, and that one feature explains a good share of the calls we get from here.
Crawling insects in Glencairn: what we see
Scorpions and rain spiders turn up near rockeries and retaining walls on the slopes. Fishmoths thrive in damp, closed-up holiday homes, and ants trail in from sandy gardens in summer.
Homes on the heights are mostly freestanding family houses with big windows and decks, some built into the slope with retaining walls and dark storerooms underneath. Down near the water there are older holiday cottages, some with timber floors and roofs that take a beating from salt air. Holiday lets stand empty for weeks and then fill up, which gives rodents time to settle in unnoticed.
The Glencairn wetland catches water coming off the mountain before it reaches the sea, and in warm weather its still margins breed mosquitoes. Fynbos slopes and Table Mountain National Park land rise behind the village, bringing scorpions, rain spiders and the odd snake into gardens. Chacma baboons also pass through on the higher streets, so bins left out attract more than flies. Sea mist and winter rain keep timber and storerooms damp.
How to tell you have a problem
- You keep finding small pale spiders in bedding, curtains or clothing that has been left folded.
- Fresh webs reappear in the same corners, window frames and eaves within days of being brushed down.
- 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.
Worth knowing
Spraying the skirting boards in every room is usually a waste. Spiders spend the day in voids, roof spaces and behind fitted units, so that is where the treatment needs to go.
How we handle spider control in Glencairn
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
- Fit fine mesh to vents and seal the gaps around pipes and under doors with sealant or brush strips.
- Shake out shoes, gardening gloves and clothes that have been left on the floor or in the garage before you put them on.
- Pull beds slightly away from the wall and keep bedding off the floor to reduce night-time bites from sac spiders.
- Swap white outdoor bulbs for warm yellow or LED ones so fewer insects gather, which means fewer spiders setting up around your doors.
- Keep stacked wood, bricks and old pots away from the house walls, because these are prime spots for button spiders.
What affects the price
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.
Honestly, a broom, a vacuum and better outdoor lighting solve a lot of spider complaints without any chemical at all. Supermarket aerosols kill the spider you spray but do little for the ones in the roof void or wall cavity. If you suspect violin or button spiders, or you are seeing bites, get it looked at properly rather than guessing.
Questions we get asked in Glencairn
Why do I have so many spiders this year?
Usually because there is more for them to eat. A warm spell, a lot of outdoor lighting or an underlying insect problem will bring spiders in behind it.
Can you treat a Glencairn holiday home while I'm away?
Yes, we can arrange access with a neighbour or agent and send you a post-treatment report afterwards. Photo identification via WhatsApp also helps you check what was found.
Does the Glencairn wetland cause the mosquitoes in my house?
It is a big source, especially in warm, still weather. Screening windows, emptying standing water in the garden and a targeted treatment around the house cut the numbers down.
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 come out to Glencairn for spider control?
Yes. Glencairn is part of our regular South Peninsula route, along with Simon's Town, Fish Hoek, Sun Valley, Clovelly. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
How long does a spider treatment last?
A residual treatment keeps working for a good while, and our treatments carry a minimum 3-month guarantee. New spiders can still wander in from the garden, which is why sealing gaps and fixing outdoor lighting matters.
