Ask a Capetonian about the Southern Suburbs and they will picture oak-lined avenues, the mountain looming over Newlands and the rain that rolls in off it in winter. Those same oaks, gardens and wet months are why squirrels, rats, ants and wood borer make up so much of our work between Rondebosch and Constantia.

Crawling insects in Southern Suburbs: what we see
Argentine ants run long trails into kitchens and bathrooms in summer, often from the garden beds along the house. Fishmoths thrive in damp built-in cupboards and bookshelves, and rain spiders wander in from the garden.
The housing spans Victorian semis in Rondebosch and Claremont, big Edwardian and mid-century family homes in Newlands and Bishopscourt, student digs near UCT, blocks of flats around Wynberg and Claremont, and old farm-style homesteads and estates in Constantia. Many older homes have suspended timber floors, deep roof voids and outbuildings that rodents and squirrels quickly claim. Thatched roofs and gabled homesteads in Constantia bring their own timber and rodent issues.
This side of Table Mountain catches far more rain than the rest of the city, and Newlands is among the wettest suburbs in Cape Town. Kirstenbosch, Newlands Forest and the mountain slopes border the upper edge, while the Liesbeek River winds through Newlands and Rondebosch toward the Black River. Winter damp encourages fishmoths and borer, and the canopy of oaks and pines keeps grey squirrels well supplied.
From the technician
Fishmoths are often a sign of damp more than dirt. If you keep finding them in the same bathroom or cupboard, it is worth checking for a slow leak or poor ventilation.
How to tell you have a problem
- Crickets chirp loudly from inside the house at night but go quiet when you get close.
- There is a faint musty, oily smell in a cupboard that has not been opened for a while.
- Dead insects collect on window sills, in light fittings or along the bottom of the garage door.
- Ant trails run from a crack in the floor or wall to the dog bowl, sugar bowl or dishwasher.
- Brown oval egg cases are tucked into hinges, under drawers or behind the stove.
How we handle crawling insect control in Southern Suburbs
Crawling insects walk through treated areas and carry baits back to their nests, which is exactly why baits and dusts work so well on them. We use gel baits in cracks and hinges for cockroaches and slow-acting ant baits that the workers take home to the queen. Insect growth regulators stop young cockroaches from maturing and breeding, which matters for German cockroaches that multiply fast. Residual sprays are applied as a barrier along entry points, door thresholds and drain areas rather than across open floors. Dusts go into wall voids, ceiling spaces and plug points where liquids should not be used.

Stopping a repeat visit
- Do not leave dishes in the sink overnight, since a wet sink is a feeding station for cockroaches.
- Move firewood, compost and piles of bricks away from the house walls.
- Put drain covers or mesh over floor drains and keep the water traps full, especially in guest bathrooms that are seldom used.
- Store books and documents in sealed plastic boxes in dry rooms rather than in damp garages.
- Check second-hand furniture, appliances and cardboard boxes before bringing them inside, as German cockroaches often move house this way.
What affects the price
Cost is driven by the species and how established the infestation is, with German cockroaches in a busy kitchen usually needing more work than a one-off ant trail. The size of the property, the number of units or rooms affected, and access to roof spaces and drains also matter. Where a follow-up treatment is needed to catch hatching insects, or where a business wants a regular service contract, we build that into a free quote upfront.
Shop-bought ant baits can handle a small, new trail and are worth a try. For cockroaches, especially German cockroaches, DIY sprays usually make things worse by scattering them and killing only the adults while the egg cases hatch. In flats and food businesses, I would not bother with DIY at all.
Questions we get asked in Southern Suburbs
What counts as a crawling insect?
Anything that mainly walks rather than flies: cockroaches, ants, fishmoths, crickets, earwigs, millipedes and scorpions. They hide in cracks and voids, which is why they are treated with baits, dusts and barriers.
Do I need a beetle certificate to sell an old house in the Southern Suburbs?
In most sales, yes, it is a condition of the deed of sale. Older homes with timber floors and roof beams are inspected closely, so it is worth checking before you list.
How do I get grey squirrels out of my roof in the Southern Suburbs?
The first step is finding and sealing every entry point once the squirrels are out, usually along fascias near trees. We can inspect your roof and advise on proofing and safe removal.
Can crawling insects come from my neighbour?
Yes, particularly in flats, townhouses and semi-detached homes that share walls, drains and roof spaces. Treating several units together gives much better results.
Why do ants keep coming back after I spray them?
Spraying kills the foragers but leaves the queen and the nest untouched. Baits work better because the workers carry the product back and share it with the colony.
Do you come out to Southern Suburbs for crawling insect control?
Yes. Southern Suburbs is part of our regular Southern Suburbs route, along with Rondebosch, Claremont, Newlands, Wynberg. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
