Marina da Gama is built around a network of canals off Zandvlei, with houses that back right onto the water and little jetties at the end of the garden. Living on the water is lovely, but it also means midges, mosquitoes and rats are part of the conversation.
Timber pests around Marina da Gama
Wooden decks, jetties and boathouses take a beating from moisture and are at risk from wood borer. Regular checks and treatments help protect them.
Most homes are free-standing houses and townhouses from the 1970s onwards, many with timber decks, boathouses and jetties on the canals. The decks and boathouses give rats and spiders plenty of hiding spots. Tightly spaced houses mean a rodent problem next door can quickly become yours.
The canals connect to Zandvlei, a large estuary with reed beds and wetlands that open to False Bay. Warm, still water in summer is perfect for midges and mosquitoes. The South-Easter blows hard across the vlei, and winter storms can push the water level up.
Midges and mosquitoes are the main seasonal pests. Rats live along the canals and under decks. Spiders, fishmoths and ants are common inside homes near the water.
A note from the field
Cables running through thatch should be in conduit. Rodent damage to a bare cable in a thatch roof is a fire risk that is easy to prevent.
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.
Signs to look for
- Small round exit holes in the poles, especially in the paler sapwood.
- Birds pulling reed out of the roof or nesting under the eaves.
- Tunnels or loose patches in the thatch where rodents have been moving.
- Insects such as cockroaches or spiders falling from the ceiling.
- Fine powder dropping from the poles or laths onto floors and furniture below.
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.
Prevention that actually works
- 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.
- 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.
- Do not store firewood or boxes against the walls under the thatch, as they give insects and rodents cover.
What affects the price
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.
Thatch Treatment questions from Marina da Gama
Do you come out to Marina da Gama for thatch treatment?
Yes. Marina da Gama is part of our regular South Peninsula route, along with Muizenberg, Lakeside, Lavender Hill, Steenberg. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
Are there rats under my deck by the canal?
Quite possibly. The space under decks and jetties is dark and sheltered, close to water, so rats like it. We can inspect, bait safely and seal off access.
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.
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.
Can you get rid of the midges in Marina da Gama?
Not completely, because they breed in Zandvlei itself, which we can't treat. We can reduce resting midges around your home and advise on lighting and screens to keep them out.
