Rondebosch is old Cape Town: oak trees, Victorian houses, big schools and the UCT campus spilling down the slope toward Main Road. Between the students, the historic buildings and the squirrels, there's rarely a quiet week for pest work here.
The local picture in Rondebosch
German cockroaches spread quickly in student houses with shared kitchens. Fishmoths like the old built-in cupboards, and Argentine ants trail in during dry spells.
There's a real mix. Victorian and Edwardian homes with timber floors and pressed-ceiling roofs sit next to student digs, blocks of flats and large school and university buildings. Old houses split into rental rooms mean lots of people sharing kitchens, which is where cockroaches thrive. High ceilings and wide roof voids give squirrels and rats plenty of room.
The Liesbeek River runs through Rondebosch and Rondebosch Common is a large open space in the middle of the suburb. Table Mountain's eastern slopes and the forests above Newlands bring heavy winter rain and a lot of tree cover. Damp, shady gardens and river banks are good rat and mosquito habitat.
Squirrels and roof rats are the headline problem, followed by German cockroaches in shared student kitchens. Bed bugs are a known risk where tenants change every year. Wood borer in old timber comes up often when houses are sold.
What gives them away
- Egg sacs, often round and papery or spiky in the case of the brown button spider, are stuck to brickwork or furniture.
- 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.
- Untidy, tangled webs show up under outdoor chairs, in the meter box or around the pool pump.
- Someone in the house wakes with a small, red, sometimes blistered bite that was not there the night before.
A note from the field
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.
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.
- 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.
- 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.
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.
Spider Control questions from Rondebosch
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 Rondebosch for spider control?
Yes. Rondebosch is part of our regular Southern Suburbs route, along with Newlands, Rosebank, Claremont, Rondebosch East. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
Why are there so many squirrels in Rondebosch ceilings?
The suburb's old oaks are a huge food source, and old roofs have gaps under the eaves that squirrels chew wider. Once they're out, the gaps need to be closed or new ones move in.
Can you treat a student house in Rondebosch during the holidays?
Yes, holidays are the best time because rooms are empty and can be treated properly. Weekend and after-hours visits can also be arranged on request.
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.
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.
