Lansdowne is a busy, settled suburb where Lansdowne Road and Jan Smuts Drive bring a steady stream of traffic and trade. Shops, mosques, schools and family homes all sit close together, so pest pressure is a mix of household and commercial.
Timber pests around Lansdowne
Older roofs with pine trusses and wooden floors can harbour wood borer. Beetle inspections are available when you're buying or selling.
The housing is mostly single-storey brick homes and semi-detached houses on modest stands, many extended over the years with extra rooms at the back. Every add-on creates new joins in the roof and walls, and those gaps are where mice and cockroaches get in. Along the main roads, shops with flats above share walls and ceilings, which lets rodents travel between them.
It's flat Cape Flats country with sandy soil that drains fast in summer and stays soggy in a wet winter. Stormwater canals run through the wider area and carry water most of the rainy season. Strong South-Easter winds in summer blow litter into corners and against fences, giving rodents cover.
House mice and rats are the most common call, followed by German cockroaches in kitchens and shops. Ants march in every summer. Flies are a nuisance near takeaways and around bins.
How to tell you have a problem
- Tunnels or loose patches in the thatch where rodents have been moving.
- Small round exit holes in the poles, especially in the paler sapwood.
- Birds pulling reed out of the roof or nesting under the eaves.
- Fine powder dropping from the poles or laths onto floors and furniture below.
- Droppings on beams or along the top of walls under the thatch.
Borer in the poles and laths weakens the timbers that carry the weight of the thatch, which is heavy, and serious damage can mean replacing structural members. Rodents nesting in thatch chew electrical cables, and in a thatch roof that is a fire risk to take seriously. Insects dropping from an open thatch ceiling are a nuisance in homes and a real problem in guest lodges and restaurants. Bird nests in thatch can bring mites into bedrooms below.
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.
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.
- Do not store firewood or boxes against the walls under the thatch, as they give insects and rodents cover.
- Fit bird netting or wire at the eaves if birds keep pulling reed or nesting there.
- Keep trees and creepers trimmed back from the thatch so rodents cannot step straight onto the roof.
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.
Thatch Treatment questions from Lansdowne
Do you treat the thatch for fire?
No, fire retardant treatment is a specialist job for thatching contractors. We treat the pests in the roof and will point out if the thatch looks like it needs attention.
Do I need to move out?
Usually not. We will tell you which rooms to keep clear during treatment and for how long.
Do you treat shops and restaurants on Lansdowne Road?
Yes. We do cockroach, rodent and fly control for food businesses and provide a post-treatment report you can keep on file.
Do you come out to Lansdowne for thatch treatment?
Yes. Lansdowne is part of our regular Southern Suburbs route, along with Crawford, Kenwyn, Rondebosch East, Athlone. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
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 mice in my ceiling but never see them in the house?
They are probably nesting in the roof space and feeding outside or in the kitchen at night. In Lansdowne this often happens where an extension joins the original roof, so we start our inspection there.
