Kalk Bay is squeezed between the mountain and the sea, with a busy fishing harbour, Main Road restaurants and old cottages stacked up the slope. Fish, food and old buildings together mean rats, cockroaches and gulls are part of daily life.
Crawling insects around Kalk Bay
German cockroaches thrive in busy restaurant kitchens along Main Road, and American cockroaches use old drains. Fishmoths like the damp in older cottages.
Most homes are old fishermen's cottages and Victorian houses built close together on steep ground, many with timber floors and pitched roofs. Along Main Road there are shops, galleries and restaurants in older buildings. Old stonework, retaining walls and underfloor voids give rodents plenty of hiding places.
The mountain rises steeply behind the village, with Boyes Drive cutting across the slope, and the railway runs right along the sea. The harbour brings in fish and gulls daily. Salt spray and the South-Easter keep things damp in winter and windy in summer.
Rats around the harbour and restaurant bins top the list. German cockroaches are common in restaurant kitchens, and American cockroaches come up from old drains. Gulls and pigeons are a constant nuisance.
Tell-tale signs
- Cast skins and dead insects collect along skirting boards and in the backs of cupboards.
- Outside lights draw a cloud of moths and midges each night with webs built right around them.
- Untidy, tangled webs show up under outdoor chairs, in the meter box or around the pool pump.
- 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.
A note from the field
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 the treatment works
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
- Brush down webs regularly and vacuum the corners and the backs of cupboards, which gets rid of egg sacs before they hatch.
- Pull beds slightly away from the wall and keep bedding off the floor to reduce night-time bites from sac spiders.
- Fit fine mesh to vents and seal the gaps around pipes and under doors with sealant or brush strips.
- Keep stacked wood, bricks and old pots away from the house walls, because these are prime spots for button spiders.
- Shake out shoes, gardening gloves and clothes that have been left on the floor or in the garage before you put them on.
Pricing, honestly
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.
Questions we get asked in Kalk Bay
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 the rats in Kalk Bay come from the harbour?
Many do. The harbour and restaurant bins are a reliable food source, so rats move into nearby homes and shops, and we focus bait stations and proofing on those routes.
Do you come out to Kalk Bay for spider control?
Yes. Kalk Bay is part of our regular South Peninsula route, along with St James, Muizenberg, Fish Hoek, Clovelly. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
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.
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.
Why do gulls keep nesting on my roof in Kalk Bay?
Flat or low-pitched roofs near the harbour are ideal nesting spots, and there is plenty of food nearby. Bird proofing with spikes, wires or netting before the breeding season keeps them off.
