Constantia means big plots, old oaks, vineyards and horses, so pest control here is often as much about the garden and outbuildings as the house itself. Squirrels in the roof, rats around the stables and wasps in the hedges are everyday conversations in the valley.
Timber pests in Constantia: what we see
Thatch sits on timber poles and battens, and older Cape Dutch homes have heavy beams that deserve a proper look for borer. Beetle certificates are commonly required on Western Cape sales, and big, older houses are where infestations most often turn up.
Many homes are large, older properties on generous stands, some Cape Dutch in style with thatched roofs, others modern with big glass walls and pool decks. Staff cottages, garages, stables and pool houses all add extra buildings that need checking. Thatch and exposed beams give rodents and borer beetles places that are hard to reach once they're established. The newer security estates have neater gardens but still back straight onto greenbelts.
Rodents lead the list, helped by horse feed, chicken coops, compost and all those outbuildings. Grey squirrels getting into roof spaces is a very Constantia problem. Paper wasps under eaves and in clipped hedges are a summer staple, and older thatch and timber bring borer questions whenever a house changes hands.
Signs to look for
- Small round or oval exit holes in timber, furniture or floorboards.
- Fine powder, called frass, building up under wooden items or on the floor below roof timbers.
- A beetle inspection for a property transfer has flagged activity.
- 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.
Worth knowing
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.
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.

Prevention that actually works
- If you are buying or selling, book the beetle inspection early so it does not delay the transfer.
- 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.
- 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.
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.
Questions we get asked in Constantia
Can you stop squirrels getting into my roof in Constantia?
Yes, but the lasting fix is physical. We find where they are getting in, usually a fascia gap or loose ridge tile next to an oak branch, and advise on sealing it once the roof is empty; cutting branches back from the roof helps a lot.
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.
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.
Does a thatched roof in Constantia need special treatment for borer?
The grass itself is not what borers are after, but the poles and battens holding it up can be. We inspect the visible timber for fresh holes and dust and treat only if there is active infestation.
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 you come out to Constantia for wood borer treatment?
Yes. Constantia is part of our regular Southern Suburbs route, along with Bergvliet, Tokai, Plumstead, Diep River. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
