De Waterkant is tiny, steep and packed: painted cottages, cobbled lanes, restaurants and a lot of short-term rentals. Pest work here revolves around kitchens, guest turnover and the old drains under the streets.
Crawling insects in De Waterkant: what we see
German cockroaches are the headline problem in restaurants and the flats above them. Ants and fishmoths turn up in older cottages with thick plastered walls.
The core is a cluster of restored old cottages and terraced houses, many now guesthouses or holiday flats, alongside newer apartment blocks and the Cape Quarter shops. Shared walls and linked roof spaces let rodents and cockroaches travel from unit to unit without ever going outside. Conversions often leave hidden voids behind kitchen fittings. Restaurants on the ground floor with flats above are a common setup.
German cockroaches in restaurant kitchens, rats in drains and ceilings and bed bugs in busy rentals are the big ones. Pigeons and gulls on rooftops and terraces round it out.
How to tell you have a problem
- Someone in the house wakes with a small, red, sometimes blistered bite that was not there the night before.
- 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.
- Fresh webs reappear in the same corners, window frames and eaves within days of being brushed down.
The vast majority of local spiders pose no real threat to people, and they do a decent job of keeping insect numbers down. Violin and sac spider bites can cause tissue damage that needs medical attention, and button spider venom is neurotoxic, so a bite from one should always be seen by a doctor. In businesses such as guest houses, clinics and food premises, visible webs and spiders lead to complaints and can count against you on a hygiene inspection.
Worth knowing
The first thing a technician checks is not the spider but what it is eating. Bright security lights, damp areas with lots of small insects, or an ant trail along the wall will keep drawing spiders in no matter how often you spray.
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
- Swap white outdoor bulbs for warm yellow or LED ones so fewer insects gather, which means fewer spiders setting up around your doors.
- Pull beds slightly away from the wall and keep bedding off the floor to reduce night-time bites from sac spiders.
- Shake out shoes, gardening gloves and clothes that have been left on the floor or in the garage before you put them on.
- Brush down webs regularly and vacuum the corners and the backs of cupboards, which gets rid of egg sacs before they hatch.
- Keep stacked wood, bricks and old pots away from the house walls, because these are prime spots for button spiders.
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.
Spider Control questions from De Waterkant
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.
Why do cockroaches keep appearing in my flat above a restaurant?
German cockroaches move up service ducts and pipe gaps from busy kitchens. Treating your flat helps, but it works best when the restaurant below is treated at the same time.
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.
Do you come out to De Waterkant for spider control?
Yes. De Waterkant is part of our regular City Bowl & Atlantic Seaboard route, along with Green Point, Bo-Kaap, Foreshore, Malay Quarter. 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.
Do bed bugs spread between units in De Waterkant's terraced houses?
They can, through shared walls, plug points and gaps around pipes. If one unit has them, we recommend inspecting the rooms on either side as well.
