Pinelands was laid out as South Africa's first garden city, and its tall trees, wide verges and old thatched cottages still define it. Those same trees and roofs bring squirrels, rats and thatch beetles to our list here.
Pinelands: what drives timber pests here
Thatched roofs and old timber floors are prone to borer and thatch beetles. Beetle certificates are especially important here when homes sell.
Many homes are original cottages from the 1920s and 1930s, some still with thatched roofs, along with later brick houses and townhouse complexes. Big gardens and overhanging trees give rodents and squirrels easy access to roofs. Older timber floors and roof structures are prone to borer. Outbuildings, garages and garden sheds are common hiding places.
Pinelands is full of mature pines, oaks and green belts, with the Black River and Raapenberg bird sanctuary on its western edge. Winter rain keeps gardens damp, and summers are warm with the South-Easter. Green spaces and water attract birds and insects.
Squirrels and rats in roofs are the most common calls, along with thatch and wood borer problems. Mosquitoes near the river and Egyptian geese in parks are regular issues. Fishmoths and ants appear in older homes.
Something most people miss
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.
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.
Signs to look for
- Insects such as cockroaches or spiders falling from the ceiling.
- Droppings on beams or along the top of walls under the thatch.
- Fine powder dropping from the poles or laths onto floors and furniture below.
- Rustling or scratching in the roof at night.
- Birds pulling reed out of the roof or nesting under the eaves.
- Tunnels or loose patches in the thatch where rodents have been moving.
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.
What happens when we come out
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
- Do not store firewood or boxes against the walls under the thatch, as they give insects and rodents cover.
- 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.
- Have electrical wiring in the roof inspected regularly, especially if you have had rodents.
- 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.
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.
Frequently asked questions
Will the treatment damage my thatch?
No. We treat the timbers directly and keep any treatment of the thatch itself light and targeted.
Is there a guarantee?
Our treatments carry a minimum 3-month guarantee, and the report records exactly what was treated.
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 you come out to Pinelands for thatch treatment?
Yes. Pinelands is part of our regular Southern Suburbs route, along with Thornton, Ndabeni, Langa, Mowbray. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
Why are there squirrels in my Pinelands roof?
The tall trees give them easy access to roofs, and they nest in warm, dry spaces. We remove them and seal entry points.
Do Pinelands thatched cottages get borer?
Yes, older thatch and timber often show borer activity. We inspect the thatch and roof timbers and advise on treatment.
