Sun Valley is a family suburb tucked in the valley between Fish Hoek and Noordhoek, with mountains close on both sides. Homes back onto fynbos, green belts and wetland, so a lot of the pests we see here walk in from the bush rather than from neighbours.
Timber pests in Sun Valley: what we see
Wooden decks, pergolas and timber ceilings are worth checking for wood borer every few years. A beetle certificate is usually needed when selling, and it is cheaper to find problems early.
The area is mostly freestanding homes from the eighties and nineties, plus newer townhouse complexes and a few security estates. Plenty of houses have big gardens, pool pumps, wooden decks and garden sheds, all of which give rodents and spiders somewhere to hide. Some homes have timber ceilings and exposed beams that need watching for borer.
The Silvermine side of the Table Mountain National Park is right above the suburb, and the low ground towards Noordhoek and the Fish Hoek valley holds water in winter. That mix of mountain fynbos and wet valley floor brings rodents and plenty of crawling insects right to the back fence. The valley also gets cooler, damp nights that suit fishmoths and mould.
Rats and field mice moving in from the green belts are a steady issue, especially once the winter rains start. Ants, crickets, spiders and the odd scorpion are common in garden-heavy properties. Mosquitoes are worse near the wetland edge, and timber pests matter in homes with wooden decks and ceilings.
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.
What gives them away
- Timber that breaks easily and shows a network of tunnels inside.
- Adult beetles found on windowsills or near lights in late spring and summer.
- Fine powder, called frass, building up under wooden items or on the floor below roof timbers.
- Floorboards that feel soft or crumble at the edges when you press on them.
- A beetle inspection for a property transfer has flagged activity.
- Small round or oval exit holes in timber, furniture or floorboards.
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
- Seal or varnish bare wood surfaces, because beetles prefer to lay eggs in rough, untreated grain.
- 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.
- Have the roof timbers looked at every few years in an older house.
- 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.
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 Sun Valley
Do you come out to Sun Valley for wood borer treatment?
Yes. Sun Valley is part of our regular South Peninsula route, along with Sunnydale, Fish Hoek, Noordhoek, Masiphumelele. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
Do the rats in Sun Valley come from the mountain or from neighbours?
Mostly from the green belts and wetland edges, especially after the first winter rains. Sealing roof and garage gaps on the bush-facing side of your home makes the biggest difference.
Are scorpions in Sun Valley dangerous?
Most scorpions found here are mild, but some thick-tailed species can give a painful sting, so treat any sting with caution and get medical advice if symptoms are severe. We can reduce numbers around your home by clearing harbourage and treating hiding spots.
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.
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 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.
