Harfield Village is a pocket of narrow streets and old cottages squeezed between Claremont and Kenilworth, with plenty of cafes and restaurants on the main drag. Old buildings, lots of trees and food businesses close together mean rodents and cockroaches are always in the picture.
The local picture in Harfield Village
Old pine floors, skirting and roof timbers are prime territory for common furniture beetle. If you are selling, a beetle certificate inspection is routine and we can check the roof void and underfloor for you.
Most homes are semi-detached Victorian and Edwardian cottages with timber floors, suspended underfloor voids and pitched roofs. Many have been renovated, but the old air bricks, gaps around pipes and loose roof sheeting are still there. Those voids are perfect runways for rats and mice, and old timber floors and roof beams can carry wood borer.
The village lies on the flat between the railway line and the Southern Suburbs' leafy belt, with Table Mountain's eastern slopes not far off. Big oaks and plane trees drop leaves into gutters, and winter rain here is heavier than on the Cape Flats. Damp underfloor areas in winter attract fishmoths and give rodents a dry place to nest above the wet.
Roof rats and mice in ceilings and underfloor voids are the most common call. Cockroaches spread from restaurants and takeaway kitchens, and fishmoths like the old cupboards and bookshelves. Grey squirrels are a regular nuisance in the trees and roofs.
How to tell you have a problem
- Insects such as cockroaches or spiders falling from the ceiling.
- Rustling or scratching in the roof at night.
- Small round exit holes in the poles, especially in the paler sapwood.
- Droppings on beams or along the top of walls under the thatch.
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.
Cables running through thatch should be in conduit. Rodent damage to a bare cable in a thatch roof is a fire risk that is easy to prevent.
How the treatment works
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 electrical wiring in the roof inspected regularly, especially if you have had rodents.
- Have open thatch ceilings in lapas and lodges checked once a year, since problems are easy to see early.
- Keep trees and creepers trimmed back from the thatch so rodents cannot step straight onto the roof.
- 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.
How much will it cost?
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.
Frequently asked questions
Do you come out to Harfield Village for thatch treatment?
Yes. Harfield Village is part of our regular Southern Suburbs route, along with Claremont, Kenilworth, Newlands, Rondebosch. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
Do Harfield's old cottages need a beetle certificate when they are sold?
Usually yes, the buyer's bank or the sale agreement will ask for one. We inspect the accessible roof timbers and underfloor areas and report on any active infestation.
Do I need to move out?
Usually not. We will tell you which rooms to keep clear during treatment and for how long.
How do I know if the borer is still active?
Fresh, pale powder below the poles and clean-edged holes point to active borer. We can tell you on inspection, or send us a photo on WhatsApp first.
Why do I hear scratching under my floorboards at night?
In Harfield's raised-floor cottages it is almost always mice or rats nesting in the underfloor void. We find where they are getting in through air bricks or pipe gaps, bait, and seal up the entry points.
Will the treatment damage my thatch?
No. We treat the timbers directly and keep any treatment of the thatch itself light and targeted.
