Salt River is old industrial Cape Town: terraced cottages, converted factories, the rail yards and Voortrekker Road traffic. It's a working neighbourhood with lots of food businesses, and that combination means rodents and cockroaches are always on the agenda.
Salt River: what drives timber pests here
Old pine floors and roof timbers in the Victorian terraces are prone to wood borer, and sales often call for a beetle certificate.
Rows of narrow Victorian terraced houses share walls and roofs, so a rat or cockroach problem in one house quickly reaches the next. Old factories and warehouses have been turned into studios, offices and flats, and many still have old drains and gaps around pipes. Shops, bakeries and takeaways on Voortrekker and Victoria roads need ongoing commercial control.
Rats are the biggest pressure, followed closely by German cockroaches in kitchens and food businesses. Flies and pigeons are steady problems around commercial buildings. Bed bugs turn up in rented rooms and backpacker accommodation.
How to tell you have a problem
- Droppings on beams or along the top of walls under the thatch.
- Birds pulling reed out of the roof or nesting under the eaves.
- Insects such as cockroaches or spiders falling from the ceiling.
- Tunnels or loose patches in the thatch where rodents have been moving.
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.
How the treatment works
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
- Do not store firewood or boxes against the walls under the thatch, as they give insects and rodents cover.
- 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.
- Have open thatch ceilings in lapas and lodges checked once a year, since problems are easy to see early.
- Keep trees and creepers trimmed back from the thatch so rodents cannot step straight onto the roof.
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.
Frequently asked questions
Can you treat a lapa or braai area?
Yes, lapas are often the easiest to treat because the whole structure is open underneath.
Is there a guarantee?
Our treatments carry a minimum 3-month guarantee, and the report records exactly what was treated.
Will the treatment damage my thatch?
No. We treat the timbers directly and keep any treatment of the thatch itself light and targeted.
Do you come out to Salt River for thatch treatment?
Yes. Salt River is part of our regular Southern Suburbs route, along with Woodstock, Observatory, Maitland, Upper Woodstock. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
Do the rats in Salt River come from the canal?
Many do. The Salt River canal and the rail reserve give rats water and cover, and they move into homes and shops through drains and gaps around pipes.
Can you service my Salt River restaurant without closing during trading hours?
Yes, we can come after hours or on weekends on request so trading isn't interrupted. We'll also leave a written report for your records.
