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.
De Waterkant: what drives flying insects here
Fruit flies and drain flies are a restaurant headache around bars and floor drains. On hot, windless days, flies gather at the bin stores.
The suburb sits on the lower slope of Signal Hill, at the edge of the city centre and a short walk from the harbour. In summer the South-Easter funnels down the streets and packs litter into corners and gutters. Winter rain rushes down the slope into old stormwater lines, which is when rats move indoors.
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.
What gives them away
- You hear whining at night and wake up with fresh bites on exposed arms and ankles.
- Tiny moth-like flies sit on bathroom walls near the shower or basin drain.
- A sudden swarm of large blowflies appears indoors, which often points to something dead in the roof or wall.
- Flies keep gathering around the same window, light or rubbish area even after you have cleaned and sprayed.
- Small moths flutter out of the pantry or out of a cupboard full of woollens.
- Small flies hover over the fruit bowl, the recycling bin or the drip tray under a bar tap.
From the technician
For landlords, flying insect complaints often come down to maintenance: a cracked drain, a missing window screen or a bin area that floods. Fixing those is cheaper than repeat treatments.
How we handle flying insect control in De Waterkant
We start by identifying the insect properly, because a drain fly needs a completely different fix from a house fly or a mosquito. Breeding sites come first: drains are cleaned out and treated with a larvicide or bio-enzyme product, standing water is tipped or treated, and waste areas are sorted out. Only then do we use residual sprays on resting surfaces such as window frames and wall tops, fly bait stations away from food, and ULV fogging where a large space needs a quick knockdown. In commercial kitchens and food stores we install insect light traps with glue boards so there is constant monitoring between visits. Wasp nests are treated with a dust or spray directly into the nest and removed once the colony is dead.

Keeping them out afterwards
- Store flour, cereal and pet food in sealed containers so pantry moths have nothing to breed in.
- Fit fly screens on kitchen windows and keep a self-closing door or strip curtain on back doors that open onto bins.
- Keep wheelie bins closed, rinse them out in summer, and park them away from the kitchen door.
- Pour boiling water down slow drains weekly and scrub the inside of the drain pipe with a brush, since that slime is where drain flies breed.
- Tip out pot plant saucers, birdbaths and anything else that holds water for more than a few days.
How much will it cost?
The price depends on which insect we are treating, because a single wasp nest is a very different job from a fly problem in a large food factory. The size of the property, how many breeding sites there are and how hard they are to get at, such as roof voids or sealed drains, all affect the time on site. Commercial sites with light traps and scheduled visits are usually best quoted as a contract, and we give free quotes once we know what is flying.
Fly swatters, screens and a good bin routine handle a lot of household fly problems, and we would rather you did that than empty a can of spray into the kitchen. Where DIY falls down is when the source is hidden, like a dead rat in the ceiling, a broken drain under the floor or a wasp nest in a wall cavity. If you are still seeing the same insects two weeks after cleaning up, the breeding site is somewhere you have not found yet.
Frequently asked questions
Do you come out to De Waterkant for flying insect 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.
Can you treat a whole business, not just a house?
Yes. Restaurants, food factories, warehouses and offices usually go onto a contract with scheduled visits, monitoring and a report for each service.
Do insect light traps actually work?
Yes, in the right place. They catch flies that get past your doors and screens and, just as usefully, the glue boards show us what is getting in and how many, which is why food businesses rely on them.
What are the tiny flies around my bathroom drain?
They are almost always drain flies, also called moth flies. They breed in the gel-like film inside drains, so cleaning the pipe properly works far better than spraying the walls.
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.
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.
