Simon's Town is a historic naval town on False Bay, with steep streets climbing the mountain behind St George's Street. Old buildings, the sea air and the mountain on the doorstep make for a very particular set of pest problems.
Timber pests around Simon's Town
Historic timber floors, roof beams and window frames are prone to wood borer, and old buildings here often need beetle certificates when sold.
There are old stone and brick buildings from the naval history, Victorian cottages, guesthouses along the main road and newer homes on the slopes above. Many buildings have timber floors, roofs and joinery that have weathered for a long time. Guesthouses and restaurants serve a steady stream of visitors. Steep sites mean retaining walls and rockeries, which give rodents and spiders plenty of places to hide.
The town sits between False Bay and the mountains of Table Mountain National Park, with Boulders and its penguin colony on the southern side. Winters are wet and windy, and the South-Easter blows hard in summer. The mountain edge brings rodents, baboons and insects, and the sea air keeps buildings damp.
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.
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.
Signs to look for
- Floorboards that feel soft or crumble at the edges when you press on them.
- 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.
- Faint scratching or ticking sounds from roof timbers on quiet nights.
- A beetle inspection for a property transfer has flagged activity.
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 we handle wood borer treatment in Simon's Town
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.
- Inspection
We check the roof space, floors and timber features with good lighting and probe suspect wood.
- Identify the beetle
We confirm the species from the holes, frass and any beetles found, and report European house borer where required.
- Mark the damage
Active areas are mapped, and any structurally weak timber is noted for replacement.
- Spray and inject
Exposed timber is sprayed and heavily infested pieces are injected through the exit holes.
- Report and certificate
You get a written report, and where needed a Certificate of Compliance for the property transfer.
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.
- Check second-hand furniture for holes and fresh powder before you bring it home.
- 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.
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 rats in Simon's Town come from the harbour or the mountain?
Both. Homes near the waterfront tend to get rats from the harbour, while houses higher up get them from the mountain slopes.
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.
Can you treat old heritage buildings in Simon's Town without damaging them?
Yes, we choose methods that don't harm old timber, plaster or stonework, and we focus on proofing gaps carefully. We'll talk you through the plan before starting.
Will treatment smell or stain the wood?
Most borer treatments dry with little smell and do not stain bare timber. Polished furniture is treated more carefully.
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.
Do you come out to Simon's Town for wood borer treatment?
Yes. Simon's Town is part of our regular South Peninsula route, along with Glencairn, Fish Hoek, Scarborough. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
