The Bo-Kaap climbs up the slopes of Signal Hill above the city centre, with brightly painted houses, cobbled streets and the oldest mosque in South Africa on Dorp Street. Homes here are packed close together and often very old, so pests like rats, cockroaches and pigeons move easily from one roof to the next.
The local picture in Bo-Kaap
Pigeons roost on the parapets and in gaps under the flat roofs, and their droppings block roof drains. Spikes and netting work best when neighbours do their roofs together, otherwise the birds just move next door.
Most homes are flat-roofed terraced houses from the 18th and 19th centuries, many with thick walls, old timber beams and small backyards. Flat roofs and parapet walls give pigeons places to roost and nest. Shared walls and old drainage pipes let cockroaches and rodents travel between neighbours.
The suburb sits on the lower slopes of Signal Hill, with steep streets that catch the full force of the South-Easter as it comes off Table Mountain. Winter rain runs down the hill and can soak old walls, encouraging fishmoths and damp-loving insects. The city centre below provides food and shelter for rodents.
Rats from the CBD and old drains are a major issue. German cockroaches are common in older kitchens and in the growing number of guest houses and cafés. Pigeons on flat roofs and fishmoths in damp walls are frequent complaints.
A note from the field
Fake owls and shiny CDs work for about a week. Pigeons are not stupid, and once they realise the owl never moves they sit right next to it.
Proofing over an active nest is a mistake. You either trap birds inside or they break through, so the clean-out always comes first.
Tell-tale signs
- Cooing, scratching or flapping in the roof space or behind the gutters early in the morning.
- Birds regularly perching in the same spots over doorways or walkways.
- Tiny mites crawling on walls or bedding near a nest site.
- Blocked gutters and downpipes full of nesting material.
- Droppings building up on ledges, walls, windowsills or under solar panels.
Pigeon droppings are acidic, mark paintwork and roofing, and become slippery underfoot on walkways. Accumulated droppings and old nests can carry fungi and bacteria, and cleaning them up dry raises dust you do not want to breathe. Nests block gutters and cause water damage when winter rains back up into the roof. When birds leave a nest, their bird mites often wander indoors looking for a new host, which leads to itchy bites.
How we handle bird proofing in Bo-Kaap
We start by watching where the birds actually land and nest, because proofing the wrong ledge is a waste of money. Ledges and beams get bird spikes or tensioned wire systems that stop birds settling. Larger open areas such as courtyards, loading bays and light wells get bird netting fixed to a frame so birds cannot get in at all. Gaps under solar panels and roof tiles are closed with mesh or panel skirting so pigeons cannot nest underneath. Old nests and droppings are removed first, and if bird mites are present we treat the area as well.

Prevention that actually works
- Clean gutters before winter, and check for nesting material at the same time.
- Close off broken air vents, missing tiles and open eaves as soon as you notice them.
- Fit mesh skirting around new solar panels at installation, before birds discover the gap.
- Deal with the first nest quickly. Pigeons that breed on a site get attached to it.
- Do not feed pigeons near your home or business. A reliable food source keeps them coming back.
What affects the price
The cost depends on how many areas need proofing, how high they are and how much access equipment is needed. Netting a large courtyard or a warehouse roof is a bigger job than spiking a few ledges. Clean-out of heavy droppings and any mite treatment are included in the free quote once we have done the site survey.
Pigeons breed throughout the year in Cape Town, so proofing is a year-round job. We see a rush in late winter and spring when birds start nesting heavily, and again before the winter rains when people find their gutters blocked.
Frequently asked questions
Can you do commercial buildings?
Yes, a lot of our bird proofing is shops, warehouses and blocks of flats where droppings affect staff and customers.
Are Bo-Kaap's old houses more prone to wood borer?
They can be, because many still have original timber beams and floors. A proper inspection will show whether the beetles are active and what treatment is safe for heritage timber.
Do you come out to Bo-Kaap for bird proofing?
Yes. Bo-Kaap is part of our regular City Bowl & Atlantic Seaboard route, along with Malay Quarter, Schotsche Kloof, De Waterkant, City Bowl. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
Do bird spikes hurt the birds?
No. The spikes are blunt and simply stop birds from landing comfortably. They move somewhere else.
Can you stop pigeons nesting under my solar panels?
Yes. We clean out the nests and fit mesh skirting around the panel edges so birds cannot get underneath.
Why do pigeons like Bo-Kaap flat roofs so much?
The parapet walls and flat roofs give them sheltered ledges to roost and nest. Netting or spikes on parapets, plus clearing nests, usually move them on.
