Pinelands was laid out as South Africa's first garden city, and its tall trees, wide verges and old thatched cottages still define it. Those same trees and roofs bring squirrels, rats and thatch beetles to our list here.
Thatch beetles and borer in Pinelands cottages
Thatched roofs and old timber floors in Pinelands' original cottages are prone to borer and thatch beetles. Beetle certificates are especially important here when homes sell.
We inspect thatch poles, floors and roof timber, treat active borer and issue the certificate. Signs are small round holes in thatch poles, beams or floorboards, and fine powder falling onto floors and furniture. Old cottages that have been extended often have original timber hidden behind newer finishes, so we check the roof space carefully.
Winter rain keeps gardens damp, and summers are warm with the South-Easter.
Squirrels and rats in roofs are the most common calls, along with thatch and wood borer problems.
A note from the field
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.
How to tell you have a problem
Tick every sign you have noticed. It takes ten seconds.
Why it matters: 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.
- 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.
- If you are buying or selling, book the beetle inspection early so it does not delay the transfer.
- Have the roof timbers looked at every few years in an older house.
- 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.
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.
Wood Borer Treatment questions from Pinelands
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.
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 Pinelands cottages often need borer treatment?
Older thatch and timber often do. An inspection shows what's needed.
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 borer spread from furniture to my roof?
It can, which is why infested furniture should be treated or kept away from untreated timber.
Do Pinelands thatched cottages get borer?
Yes, older thatch and timber often show borer activity. We inspect the thatch and roof timbers and advise on treatment.
