Strandfontein sits right on the False Bay shoreline at the southern edge of the Cape Flats, with sand dunes on one side and Mitchells Plain on the other. It is a quieter, more settled suburb than many people assume, and the pest picture is shaped heavily by sand, wind and the wetlands next door.
Strandfontein: what drives timber pests here
Brick homes with tiled roofs mean wood borer is not common, but timber in roof trusses and older built-in cupboards is worth checking before a sale needs a beetle certificate.
Most homes are freestanding brick houses on modest plots, many extended over the years with back rooms, garages and enclosed stoeps. Those add-ons often leave small gaps where new walls meet old ones, which mice and cockroaches use. There are also shops and community facilities near the main roads and the pavilion area.
The Strandfontein wastewater works and the birding area beside it hold large open ponds, so mosquitoes and midges are part of life here, especially on still evenings. Loose Cape Flats sand blows in on the South-Easter and drifts against walls and under doors. Winter rain can leave low spots waterlogged for weeks.
Mosquitoes are the complaint we hear most in the warmer months, followed by ants that nest easily in the sandy soil. Rats and mice are common where there is open land and dumping nearby. Fleas, flies and German cockroaches round out the regular calls.
From the technician
A technician looking at a thatch roof checks the wall plates first. That is where rodents get in and where they nest, warm and dry, against the top of the wall.
Tell-tale signs
- Fine powder dropping from the poles or laths onto floors and furniture below.
- Rustling or scratching in the roof at night.
- Birds pulling reed out of the roof or nesting under the eaves.
- Tunnels or loose patches in the thatch where rodents have been moving.
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.
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.

Stopping a repeat visit
- Do not store firewood or boxes against the walls under the thatch, as they give insects and rodents cover.
- Ask your thatcher to check the poles and laths for borer whenever the roof is being repaired or re-combed.
- 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.
- Fit bird netting or wire at the eaves if birds keep pulling reed or nesting there.
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
Do you come out to Strandfontein for thatch treatment?
Yes. Strandfontein is part of our regular Cape Flats route, along with Mitchells Plain, Pelican Park, Lotus River, Grassy 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.
How do I know if the borer is still active?
Fresh, pale powder below the poles and clean-edged holes point to active borer. We can tell you on inspection, or send us a photo on WhatsApp first.
Can you treat a lapa or braai area?
Yes, lapas are often the easiest to treat because the whole structure is open underneath.
Are the mosquitoes in Strandfontein coming from the sewage works ponds?
Partly. The ponds and the wetland around them are a big breeding source, but water in gutters, pot plants and blocked drains at your own home adds to it, and that part we can help you control.
Why do ants keep coming back even after I spray in Strandfontein?
Surface spray kills the workers you can see, but the nest sits in the sand under or beside your foundations. Baiting and treating the nest area works far better than repeat spraying.
