Plumstead is a settled, leafy suburb with long-standing families, a lot of oak and jacaranda shade and older homes that have been added onto over the years. That patchwork of old and new building is what keeps us busy here.
Timber pests around Plumstead
Older suspended wooden floors and roof timbers here are prone to common furniture beetle. Plenty of Plumstead homes change hands, so beetle certificate inspections are a regular job.
You'll find solid brick semis, 1940s and 1950s bungalows with suspended wooden floors, and blocks of flats closer to Main Road. Many houses have extensions, outside rooms and converted garages, and the joins between old and new are classic entry points. Under-floor voids in the older homes hold damp, which suits cockroaches and fishmoths. Shops and takeaways along Main Road bring their own rodent and cockroach pressure.
Roof rats and squirrels in ceilings are the most common call, followed by German and American cockroaches in kitchens and drains. Fishmoths show up in older homes with damp under-floor spaces. Summer brings ants and wasps.
Signs to look for
- Tunnels or loose patches in the thatch where rodents have been moving.
- Droppings on beams or along the top of walls under the thatch.
- Small round exit holes in the poles, especially in the paler sapwood.
- Fine powder dropping from the poles or laths onto floors and furniture below.
- Birds pulling reed out of the roof or nesting under the eaves.
- Rustling or scratching in the roof at night.
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.
Worth knowing
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.
For holiday rentals and lodges, insects falling from an open thatch ceiling are the kind of thing guests photograph. An annual check before the busy season is cheap insurance.
How we handle thatch treatment in Plumstead
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.

Keeping them out afterwards
- Do not store firewood or boxes against the walls under the thatch, as they give insects and rodents cover.
- Keep trees and creepers trimmed back from the thatch so rodents cannot step straight onto the roof.
- Have open thatch ceilings in lapas and lodges checked once a year, since problems are easy to see early.
- Ask your thatcher to check the poles and laths for borer whenever the roof is being repaired or re-combed.
- Have electrical wiring in the roof inspected regularly, especially if you have had rodents.
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 Plumstead
Is there a guarantee?
Our treatments carry a minimum 3-month guarantee, and the report records exactly what was treated.
Can you treat a lapa or braai area?
Yes, lapas are often the easiest to treat because the whole structure is open underneath.
Do you come out to Plumstead for thatch treatment?
Yes. Plumstead is part of our regular Southern Suburbs route, along with Wynberg, Diep River, Southfield, Heathfield. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
I'm selling an older house in Plumstead. Do I need a beetle certificate?
Many sale agreements ask for one, so it's worth checking your offer to purchase. We can inspect the roof and floor timbers and give you a written report.
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.
Are the scratching noises in my Plumstead ceiling rats or squirrels?
If it's mostly during the day it's usually squirrels; at night it's more likely rats. Either way we inspect the eaves and roof line to find the entry point before treating.
