The Malay Quarter is the oldest part of the Bo-Kaap, with cobbled lanes, painted houses and mosques climbing the lower slopes of Signal Hill above the city. Homes here are old, close together and full of history, which means pest control has to be careful as well as thorough.
Timber pests around Malay Quarter
Old timber beams, floors and window frames are at high risk of wood borer. We do beetle inspections and treatments that respect the heritage character of the buildings.
Many of the houses date back to the 1700s and 1800s, built as flat-roofed, terraced homes with thick walls and timber floors. Neighbours share walls and parapets, so rodents and cockroaches can move along a row. Older timber windows, doors and roof beams make wood borer a real concern.
Rats and mice are common in the older terraces and in the lanes. Cockroaches and fishmoths like the damp walls and old cupboards. Pigeons are a constant on the rooftops and ledges.
Tell-tale signs
- Droppings on beams or along the top of walls under the thatch.
- Small round exit holes in the poles, especially in the paler sapwood.
- Rustling or scratching in the roof at night.
- Fine powder dropping from the poles or laths onto floors and furniture below.
- Birds pulling reed out of the roof or nesting under the eaves.
Borer in the poles and laths weakens the timbers that carry the weight of the thatch, which is heavy, and serious damage can mean replacing structural members. Rodents nesting in thatch chew electrical cables, and in a thatch roof that is a fire risk to take seriously. Insects dropping from an open thatch ceiling are a nuisance in homes and a real problem in guest lodges and restaurants. Bird nests in thatch can bring mites into bedrooms below.
From the technician
Pale, fresh powder means activity; dark, compacted dust in old holes usually means the beetles left long ago. That distinction saves a lot of unnecessary treatment.
If you have a pool or pond next to a lapa, mention it. We plan treatments under thatch so nothing drifts into the water.
Our process, step by step
We start by inspecting the underside of the roof, the poles, the laths and the eaves, looking for borer exit holes, frass and rodent or bird activity. Affected poles and laths are treated with a borer spray or injection designed for timber, applied to the wood rather than soaked through the thatch. For insects living in the thatch, we use a targeted residual treatment on the underside, keeping it as light as will do the job. Rodents are handled with traps and tamper-resistant bait stations placed at wall plates and entry points, and we advise on bird netting or proofing at the eaves. Fire safety of the thatch itself, such as retardant treatment, is a separate specialist job and we will tell you if it looks overdue.
- Roof inspection
We look at the underside of the thatch, every accessible pole and lath, and the eaves and ridge.
- Identify the problem
We separate active borer from old damage and confirm which insects, rodents or birds are involved.
- Timber treatment
Affected poles and laths are treated with borer spray or injection.
- Thatch and pest treatment
Insects in the thatch are treated from below and rodent stations or traps are placed.
- Report and recommendations
You get a report noting what was treated and any timber that a thatcher or builder should replace.
Keeping them out afterwards
- Ask your thatcher to check the poles and laths for borer whenever the roof is being repaired or re-combed.
- Keep trees and creepers trimmed back from the thatch so rodents cannot step straight onto the roof.
- Have open thatch ceilings in lapas and lodges checked once a year, since problems are easy to see early.
- Have electrical wiring in the roof inspected regularly, especially if you have had rodents.
- Fit bird netting or wire at the eaves if birds keep pulling reed or nesting there.
Pricing, honestly
The price depends on the size of the roof, how much of the structure is exposed and how many poles and laths show borer activity. A small lapa with an open underside is a very different job from a double-storey home with a closed ceiling. Rodent and bird work is added where needed, and timber that is too damaged to treat has to be replaced by a builder or thatcher.
Adult borer beetles emerge mainly in the warmer months, so fresh powder and holes often appear from late spring into summer. Rodents move into thatch most during the wet Cape winters when it offers dry shelter. Treatment can be done at any time of year, though a dry day makes inspecting the roof easier.
Frequently asked questions
Do you treat the thatch for fire?
No, fire retardant treatment is a specialist job for thatching contractors. We treat the pests in the roof and will point out if the thatch looks like it needs attention.
Do I need to move out?
Usually not. We will tell you which rooms to keep clear during treatment and for how long.
Can you treat wood borer without damaging a heritage house in the Malay Quarter?
Yes. We use targeted treatments on the affected timber and avoid anything that would mark or damage original finishes, and we'll talk you through it before we start.
Is there a guarantee?
Our treatments carry a minimum 3-month guarantee, and the report records exactly what was treated.
Why do pigeons like the Malay Quarter rooftops so much?
Flat roofs and parapets give them safe places to land and nest, close to food in the city below. Spikes, wires or netting on favourite ledges usually move them on.
Do you come out to Malay Quarter for thatch treatment?
Yes. Malay Quarter is part of our regular City Bowl & Atlantic Seaboard route, along with Bo-Kaap, Schotsche Kloof, De Waterkant, City Bowl. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
