Simon's Town is a historic naval town on False Bay, with steep streets climbing the mountain behind St George's Street. Old buildings, the sea air and the mountain on the doorstep make for a very particular set of pest problems.
Simon's Town: what drives crawling insects here
Fishmoths thrive in damp old cupboards and stored books, and spiders shelter in rockeries and retaining walls. Ants come in during dry spells.
There are old stone and brick buildings from the naval history, Victorian cottages, guesthouses along the main road and newer homes on the slopes above. Many buildings have timber floors, roofs and joinery that have weathered for a long time. Guesthouses and restaurants serve a steady stream of visitors. Steep sites mean retaining walls and rockeries, which give rodents and spiders plenty of places to hide.
The town sits between False Bay and the mountains of Table Mountain National Park, with Boulders and its penguin colony on the southern side. Winters are wet and windy, and the South-Easter blows hard in summer. The mountain edge brings rodents, baboons and insects, and the sea air keeps buildings damp.
Rats and mice from the mountain edge and harbour are the main issue. Fishmoths and wood borer show up in old, damp buildings. Bed bugs are a risk in guesthouses, and gulls and pigeons are constant along the waterfront.
Tell-tale signs
- Outside lights draw a cloud of moths and midges each night with webs built right around them.
- Fresh webs reappear in the same corners, window frames and eaves within days of being brushed down.
- You keep finding small pale spiders in bedding, curtains or clothing that has been left folded.
- Egg sacs, often round and papery or spiky in the case of the brown button spider, are stuck to brickwork or furniture.
From the technician
People often kill rain spiders on sight, but they rarely bite and they eat cockroaches. If one wanders in, a container and a piece of cardboard will get it outside without any fuss.
What happens when we come out
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.

Stopping a repeat visit
- Fit fine mesh to vents and seal the gaps around pipes and under doors with sealant or brush strips.
- Brush down webs regularly and vacuum the corners and the backs of cupboards, which gets rid of egg sacs before they hatch.
- Shake out shoes, gardening gloves and clothes that have been left on the floor or in the garage before you put them on.
- 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.
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 Simon's Town
What should I do if someone is bitten?
Clean the bite, keep the spider if you can safely do so for identification, and see a doctor, especially for a suspected button or violin spider bite. Do not rely on a pest controller for medical advice.
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.
Do you come out to Simon's Town for spider control?
Yes. Simon's Town is part of our regular South Peninsula route, along with Glencairn, Fish Hoek, Scarborough. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
Can you treat old heritage buildings in Simon's Town without damaging them?
Yes, we choose methods that don't harm old timber, plaster or stonework, and we focus on proofing gaps carefully. We'll talk you through the plan before starting.
Do rats in Simon's Town come from the harbour or the mountain?
Both. Homes near the waterfront tend to get rats from the harbour, while houses higher up get them from the mountain slopes.
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.
