Rondebosch East Thatch Treatment

Rondebosch East is a quiet residential suburb of family homes, tidy gardens and long-established households. Most of the work we do here is keeping well-kept houses free of the pests that drift in from the busier roads and open land around it.

The local picture in Rondebosch East

Roof timbers on older homes can carry wood borer, and inspections are often requested when houses are sold or extended.

Homes are mostly single-storey brick houses on decent-sized plots, many extended with second storeys, granny flats or garages over the years. Tiled roofs with timber trusses are the norm. Extensions often leave small gaps where new roof meets old, and that's where rats and mynas get in. Several mosques, schools and small businesses along the main roads have their own pest needs.

The suburb sits on flat ground on the western edge of the Cape Flats, with sandy soil and open spaces such as school fields nearby. The Black River corridor and the M5 run to the west. Winters bring heavy rain and some stormwater ponding, while summers are hot and windy.

Rats and mice are the most common calls, with ants and cockroaches close behind. Fleas, wasps and pigeons round out the list in summer.

A note from the field

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.

A technician looking at a thatch roof checks the wall plates first. That is where rodents get in and where they nest, warm and dry, against the top of the wall.

How to tell you have a problem

1. Droppings on beams or along the top of walls under the thatch.
2. Rustling or scratching in the roof at night.
3. Birds pulling reed out of the roof or nesting under the eaves.
4. Tunnels or loose patches in the thatch where rodents have been moving.
5. Insects such as cockroaches or spiders falling from the ceiling.

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.

1. Roof inspection

   We look at the underside of the thatch, every accessible pole and lath, and the eaves and ridge.

2. Identify the problem

   We separate active borer from old damage and confirm which insects, rodents or birds are involved.

3. Timber treatment

   Affected poles and laths are treated with borer spray or injection.

4. Thatch and pest treatment

   Insects in the thatch are treated from below and rodent stations or traps are placed.

5. Report and recommendations

   You get a report noting what was treated and any timber that a thatcher or builder should replace.

Stopping a repeat visit

• 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.
• Have open thatch ceilings in lapas and lodges checked once a year, since problems are easy to see early.

Pricing, honestly

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.
