Langa Wood Borer Treatment

Langa is the oldest township in Cape Town and one of the most densely lived-in, bordered by the N2, Vanguard Drive and the railway. When homes, hostels and informal structures sit close together, a pest problem rarely stays in one house, so we look at the whole block rather than a single room.

Timber pests around Langa

Wood borer is less of an issue in the newer brick homes, but older hostel buildings with timber roofs can carry it. Timber in informal structures is also worth checking when damage appears.

You'll find old hostel blocks, council flats and family homes alongside newer formal housing and informal structures. Shared walls and roofs mean rats, cockroaches and bed bugs move easily from one unit to the next. Backyard rooms are common, and many households store food and goods in them, which draws rodents.

Langa sits on flat Cape Flats sand with stormwater channels and the Epping industrial area close by. Winter rain can pool on open ground and in low streets, and the drainage lines along the edges hold water long enough for mosquitoes to breed. The South-Easter carries litter and dust across open plots in summer.

A note from the field

For sellers, borer is often discovered at the worst moment, a week before transfer. Booking the inspection as soon as the house goes on the market takes the pressure off.

When we go into a roof, the first thing we look at is the condition of the wall plates and the bottom of the trusses, because damp spots there attract borer.

What gives them away

1. Faint scratching or ticking sounds from roof timbers on quiet nights.
2. Adult beetles found on windowsills or near lights in late spring and summer.
3. Floorboards that feel soft or crumble at the edges when you press on them.
4. Timber that breaks easily and shows a network of tunnels inside.
5. A beetle inspection for a property transfer has flagged activity.
6. Small round or oval exit holes in timber, furniture or floorboards.

What happens when we come out

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.

Stopping a repeat visit

• 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.
• Have the roof timbers looked at every few years in an older house.
• 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.

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.
