De Waterkant is tiny, steep and packed: painted cottages, cobbled lanes, restaurants and a lot of short-term rentals. Pest work here revolves around kitchens, guest turnover and the old drains under the streets.
Timber pests in De Waterkant: what we see
Old cottages may still have original timber floors and ceilings, and some show borer when they come up for sale and need a beetle certificate. Exposed beams in renovated homes are worth inspecting before you buy.
The core is a cluster of restored old cottages and terraced houses, many now guesthouses or holiday flats, alongside newer apartment blocks and the Cape Quarter shops. Shared walls and linked roof spaces let rodents and cockroaches travel from unit to unit without ever going outside. Conversions often leave hidden voids behind kitchen fittings. Restaurants on the ground floor with flats above are a common setup.
German cockroaches in restaurant kitchens, rats in drains and ceilings and bed bugs in busy rentals are the big ones. Pigeons and gulls on rooftops and terraces round it out.
Worth knowing
Old exit holes do not mean you have a problem today. We see plenty of furniture with holes from decades ago and no live beetles at all.
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
- Timber that breaks easily and shows a network of tunnels inside.
- Small round or oval exit holes in timber, furniture or floorboards.
- A beetle inspection for a property transfer has flagged activity.
- Floorboards that feel soft or crumble at the edges when you press on them.
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.
How the treatment works
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.
- Seal or varnish bare wood surfaces, because beetles prefer to lay eggs in rough, untreated grain.
- Use treated timber for any roofing, decking or building work, and check the treatment marks on it.
- Have the roof timbers looked at every few years in an older house.
- If you are buying or selling, book the beetle inspection early so it does not delay the transfer.
What affects the price
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.
You can brush a borer product onto a small piece of furniture yourself and it may do the job. Roof timbers are a different story: getting the product into every face of every truss in a hot, cramped roof is hard work, and missing the European house borer is a real problem. I would always get the roof looked at professionally.
Wood Borer Treatment questions from De Waterkant
Do bed bugs spread between units in De Waterkant's terraced houses?
They can, through shared walls, plug points and gaps around pipes. If one unit has them, we recommend inspecting the rooms on either side as well.
How do I know if the borer holes are still active?
Look for fresh, pale powder below the holes and clean, sharp edges on the holes themselves. Old holes are usually darker and dusty with no new frass.
Do you come out to De Waterkant for wood borer treatment?
Yes. De Waterkant is part of our regular City Bowl & Atlantic Seaboard route, along with Green Point, Bo-Kaap, Foreshore, Malay Quarter. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
Can borer spread from furniture to my roof?
It can, which is why infested furniture should be treated or kept away from untreated timber.
Why do cockroaches keep appearing in my flat above a restaurant?
German cockroaches move up service ducts and pipe gaps from busy kitchens. Treating your flat helps, but it works best when the restaurant below is treated at the same time.
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.
