Thatch Treatment in Masiphumelele

Masiphumelele, or Masi as most people call it, sits on Kommetjie Road beside the Noordhoek wetlands. It's a dense community where formal houses, backyard rooms and informal structures stand close together, so pests spread quickly from one home to the next.

Timber pests in Masiphumelele: what we see

Wooden informal structures can pick up wood borer, particularly second-hand planks and poles. The brick homes in the formal section seldom have trouble.

There are brick houses and flats in the formal part, surrounded by informal homes built from timber and corrugated iron. Shared walls, narrow lanes and limited storage space make it hard to keep food sealed, which draws rodents and cockroaches. Informal structures on low ground can be flooded in winter, pushing rats into drier homes.

Masi sits on low-lying land next to the wetland that runs towards Lake Michelle and Noordhoek. The water table is high, and winter rain often floods parts of the settlement. In summer, warm still water in the wetland breeds mosquitoes.

Something most people miss

Pale, fresh powder means activity; dark, compacted dust in old holes usually means the beetles left long ago. That distinction saves a lot of unnecessary treatment.

How to tell you have a problem

1. Insects such as cockroaches or spiders falling from the ceiling.
2. Birds pulling reed out of the roof or nesting under the eaves.
3. Rustling or scratching in the roof at night.
4. Tunnels or loose patches in the thatch where rodents have been moving.
5. Fine powder dropping from the poles or laths onto floors and furniture below.
6. Small round exit holes in the poles, especially in the paler sapwood.

Our process, step by step

We start by inspecting the underside of the roof, the poles, the laths and the eaves, looking for borer exit holes, frass and rodent or bird activity. Affected poles and laths are treated with a borer spray or injection designed for timber, applied to the wood rather than soaked through the thatch. For insects living in the thatch, we use a targeted residual treatment on the underside, keeping it as light as will do the job. Rodents are handled with traps and tamper-resistant bait stations placed at wall plates and entry points, and we advise on bird netting or proofing at the eaves. Fire safety of the thatch itself, such as retardant treatment, is a separate specialist job and we will tell you if it looks overdue.

Prevention that actually works

• Have open thatch ceilings in lapas and lodges checked once a year, since problems are easy to see early.
• Have electrical wiring in the roof inspected regularly, especially if you have had rodents.
• Do not store firewood or boxes against the walls under the thatch, as they give insects and rodents cover.
• Ask your thatcher to check the poles and laths for borer whenever the roof is being repaired or re-combed.
• Fit bird netting or wire at the eaves if birds keep pulling reed or nesting there.

What affects the price

The price depends on the size of the roof, how much of the structure is exposed and how many poles and laths show borer activity. A small lapa with an open underside is a very different job from a double-storey home with a closed ceiling. Rodent and bird work is added where needed, and timber that is too damaged to treat has to be replaced by a builder or thatcher.

Adult borer beetles emerge mainly in the warmer months, so fresh powder and holes often appear from late spring into summer. Rodents move into thatch most during the wet Cape winters when it offers dry shelter. Treatment can be done at any time of year, though a dry day makes inspecting the roof easier.
