Nyanga is one of Cape Town's oldest townships and a major transport hub, with the busy junction and taxi ranks along Klipfontein Road. High density, busy trading areas and stormwater issues all affect pest pressure here.
Timber pests in Nyanga: what we see
Borer is not a big issue in Nyanga, since most homes are brick, block or sheet metal. Where it does appear it is in damp wooden roof purlins and old door frames.
Homes range from older formal brick houses to backyard structures, hostels and informal dwellings built close together. Shared walls and tightly packed structures let rodents and cockroaches move easily between homes. Spaza shops, street traders and small food businesses operate from homes and containers. Gaps in walls and roofs, and floors at ground level, give pests easy access.
Nyanga sits on the flat, sandy Cape Flats, where winter rain can pool and flood low spots because the water table is high. The South-Easter blows sand and litter around in summer. Stormwater channels and open land nearby provide cover for rodents.
Rats are the biggest concern, followed by cockroaches and flies. Fleas and bed bugs are common in crowded living spaces. Mosquitoes breed in standing water after winter rains.
From the technician
If you have a pool or pond next to a lapa, mention it. We plan treatments under thatch so nothing drifts into the water.
Borer damage in thatch is often blamed on the reed, but the reed is rarely the problem. It is the poles and laths holding it up that the beetles are after.
How to tell you have a problem
- Droppings on beams or along the top of walls under the thatch.
- Tunnels or loose patches in the thatch where rodents have been moving.
- Rustling or scratching in the roof at night.
- Fine powder dropping from the poles or laths onto floors and furniture below.
- Small round exit holes in the poles, especially in the paler sapwood.
What happens when we come out
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.

Stopping a repeat visit
- Fit bird netting or wire at the eaves if birds keep pulling reed or nesting there.
- Have electrical wiring in the roof inspected regularly, especially if you have had rodents.
- 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.
How much will it cost?
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.
Spraying the underside of your own thatch with a garden insecticide does very little for borer, which lives inside the poles, and soaking thatch in products not meant for it can do more harm than good. We would leave borer and rodent work in thatch to someone who does it regularly. Keeping the roof clear of overhanging trees is the one thing every owner can do themselves.
Thatch Treatment questions from Nyanga
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.
Do you come out to Nyanga for thatch treatment?
Yes. Nyanga is part of our regular Cape Flats route, along with Gugulethu, Philippi, Manenberg, Hanover Park. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
Is there a guarantee?
Our treatments carry a minimum 3-month guarantee, and the report records exactly what was treated.
Why are there more mosquitoes in Nyanga after winter rain?
Rain pools on the flat, sandy ground and in blocked drains, giving mosquitoes a place to breed. Clearing standing water near homes cuts their numbers.
Can you treat a spaza shop in Nyanga for rats?
Yes. We set up bait stations and traps safely around stock and advise on sealing gaps, using the least-toxic effective method.
