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 in Marina da Gama: what we see
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.
Worth knowing
The European house borer is notifiable in the Western Cape. If we find it, it gets reported and treated properly, which is better for you in the long run.
Borer treatments are applied in the roof or to furniture, not in living areas, so children and pets just need to stay clear while we work and while it dries.
Tell-tale signs
- Fine powder, called frass, building up under wooden items or on the floor below roof timbers.
- Small round or oval exit holes in timber, furniture or floorboards.
- Floorboards that feel soft or crumble at the edges when you press on them.
- Faint scratching or ticking sounds from roof timbers on quiet nights.
- Adult beetles found on windowsills or near lights in late spring and summer.
Most borer damage is slow, but it is cumulative, and a roof truss weakened by years of tunnelling can fail under load. The European house borer is the serious one, because it goes for structural timber and is a notifiable pest. Furniture and antiques lose value quickly once borer has hollowed them out. When you sell a property in the Western Cape, an active infestation can hold up the transfer until it is treated and certified.
Our process, step by step
We start with an inspection to confirm the beetle species and whether the holes are active or old, because old damage does not need treating. Exposed timber such as roof trusses, beams and floor joists is treated with a residual borer spray that penetrates the surface and kills emerging beetles and young larvae. Where the wood is thick or the infestation is deep, we inject product directly into the flight holes and drilled galleries. Badly weakened timber should be replaced by a builder, and we tell you which pieces are past saving. Valuable furniture can be sealed and fumigated instead.

Keeping them out afterwards
- Keep the roof space ventilated and fix leaks quickly, since damp timber attracts borer.
- Use treated timber for any roofing, decking or building work, and check the treatment marks on it.
- If you are buying or selling, book the beetle inspection early so it does not delay the transfer.
- Check second-hand furniture for holes and fresh powder before you bring it home.
- Seal or varnish bare wood surfaces, because beetles prefer to lay eggs in rough, untreated grain.
Pricing, honestly
The price depends on how much timber needs treating, how easy the roof space is to get into and which beetle we are dealing with. A single piece of furniture is a very different job to a full roof of trusses. Injection work, replacement advice and certificates for transfers are all included in a free quote once we have seen the property.
Adult beetles emerge mainly from late spring through summer, roughly October to February in Cape Town, which is when fresh holes and powder show up. That is the best time to spot an active problem, but treatment can be done all year round.
Frequently asked questions
Do you come out to Marina da Gama for wood borer 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.
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.
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.
How long does the treatment last?
Residual borer treatments protect the timber for a long time. Our treatments carry a minimum 3-month guarantee, and we can re-inspect later.
Is the European house borer really that serious?
Yes. It attacks structural softwood and is a notifiable pest in the Western Cape, so suspected cases have to be reported and treated.
Do I need a beetle certificate to sell my house?
Most property transfers in the Western Cape require a beetle inspection and a Certificate of Compliance. We do the inspection and issue the certificate where the property qualifies.
