Gardens takes its name from the Company's Garden, and the squirrels in there have been raising families in neighbouring roofs for generations. Add the restaurants on Kloof Street, old Victorian semis and a lot of flats, and you get a busy mix of pest work.
Timber pests around Gardens
Victorian and Edwardian homes often have original pine or Oregon floors and roof timbers, and beetle certificate inspections regularly find borer here.
Victorian and Edwardian semis with corrugated iron roofs, broekie lace stoeps and wooden floors sit alongside blocks of flats and modern apartments. Old houses have hollow walls and suspended floors, so mice and rats can move through without being seen. Restaurants, coffee shops and bars along Kloof Street sit below residential flats. Many homes are rentals with frequent turnover.
Squirrels and roof rats in ceilings are the classic call. German cockroaches in restaurant kitchens and the flats above them come next, followed by Argentine ants and fishmoths in the old houses.
What gives them away
- Tunnels or loose patches in the thatch where rodents have been moving.
- Droppings on beams or along the top of walls under the thatch.
- Insects such as cockroaches or spiders falling from the ceiling.
- Small round exit holes in the poles, especially in the paler sapwood.
A note from the field
Borer damage in thatch is often blamed on the reed, but the reed is rarely the problem. It is the poles and laths holding it up that the beetles are after.
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.

Stopping a repeat visit
- Ask your thatcher to check the poles and laths for borer whenever the roof is being repaired or re-combed.
- Have open thatch ceilings in lapas and lodges checked once a year, since problems are easy to see early.
- Fit bird netting or wire at the eaves if birds keep pulling reed or nesting there.
- Do not store firewood or boxes against the walls under the thatch, as they give insects and rodents cover.
- Have electrical wiring in the roof inspected regularly, especially if you have had rodents.
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.
Spraying the underside of your own thatch with a garden insecticide does very little for borer, which lives inside the poles, and soaking thatch in products not meant for it can do more harm than good. We would leave borer and rodent work in thatch to someone who does it regularly. Keeping the roof clear of overhanging trees is the one thing every owner can do themselves.
Thatch Treatment questions from Gardens
Is there a guarantee?
Our treatments carry a minimum 3-month guarantee, and the report records exactly what was treated.
Do old Victorian houses in Gardens have more borer?
They often do, because many still have original timber floors and roof structures. A beetle certificate inspection will show whether there is active infestation that needs treatment.
Are the squirrels in my Gardens roof from the Company's Garden?
Very likely. Grey squirrels travel from the garden and the trees along the streets into roofs, often through gaps at the fascia. Sealing those gaps once the roof is empty is the lasting fix.
Do you come out to Gardens for thatch treatment?
Yes. Gardens is part of our regular City Bowl & Atlantic Seaboard route, along with Tamboerskloof, Oranjezicht, Vredehoek, Higgovale. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
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.
