Delft is one of Cape Town's more densely built areas, with families living close together and many extra rooms built onto the back of houses. Most calls here are about rats, cockroaches and fleas, and the best results come from treating a few neighbouring homes together.
The local picture in Delft
Borer is seldom a problem in the brick houses, but the timber frames of wendy houses and backyard rooms can be attacked. A beetle certificate may be needed if a house is sold.
Housing is mostly government-built family homes on small plots, many extended with backyard rooms, wendy houses and informal structures. Homes stand close together, and extensions built with corrugated sheeting often leave gaps at the roofline. More people and more food in a small space gives pests plenty to work with. Spaza shops run from homes add stock rooms to the picture.
Delft lies on flat, sandy ground near Cape Town International Airport and the N2. The South-Easter blows sand and litter across open ground all summer, and in winter some streets become waterlogged when stormwater drains block. Vacant land around the edges gives rodents cover.
What gives them away
- Faint scratching or ticking sounds from roof timbers on quiet nights.
- 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.
- Small round or oval exit holes in timber, furniture or floorboards.
- Timber that breaks easily and shows a network of tunnels inside.
Something most people miss
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.
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.
How we handle wood borer treatment in Delft
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.
Prevention that actually works
- 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.
- Use treated timber for any roofing, decking or building work, and check the treatment marks on it.
- If you are buying or selling, book the beetle inspection early so it does not delay the transfer.
- Seal or varnish bare wood surfaces, because beetles prefer to lay eggs in rough, untreated grain.
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.
Wood Borer Treatment questions from Delft
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.
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.
My children are getting bites at night in Delft. Is it fleas or bed bugs?
Bites around the ankles usually point to fleas, while rows of bites on arms, neck or back point to bed bugs. WhatsApp us a photo of any insect you find and we will help identify it.
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.
Can you treat my whole row of houses in Delft for rats at once?
Yes, and it works better that way. Send us the addresses and we will give a free quote for treating the properties together.
Do you come out to Delft for wood borer treatment?
Yes. Delft is part of our regular Cape Flats route, along with Belhar, Bishop Lavis, Kuils River, Nyanga. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
