Steenberg covers two quite different places: the busy residential area near Retreat and Lavender Hill, and the wine estate and golf course on the mountain side. We work across both, and the pest problems differ a lot between them.
Timber pests around Steenberg
Estate homes with timber decks and roofs can carry wood borer, and beetle certificates are requested on sales.
Near the railway and Steenberg station, homes are mainly older council houses, semis and flats, often with backyard rooms. Closer to the mountain, the estate side has newer, larger homes in security developments. Dense housing makes it easy for rodents and cockroaches to spread, while large estate homes deal more with mountain-edge pests. Shops and taxi ranks along the main roads add food sources.
The Steenberg mountain rises behind the area as part of Table Mountain National Park, with vineyards on its lower slopes. Lower down, the sandy Cape Flats ground and wetlands toward Zeekoevlei and Princess Vlei bring a high water table. Winters are wet, summers hot and windy.
Tell-tale signs
- Droppings on beams or along the top of walls under the thatch.
- Insects such as cockroaches or spiders falling from the ceiling.
- Tunnels or loose patches in the thatch where rodents have been moving.
- Fine powder dropping from the poles or laths onto floors and furniture below.
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.
From the technician
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.
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.

Keeping them out afterwards
- Have open thatch ceilings in lapas and lodges checked once a year, since problems are easy to see early.
- 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.
- 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.
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.
Questions we get asked in Steenberg
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.
Is there a guarantee?
Our treatments carry a minimum 3-month guarantee, and the report records exactly what was treated.
Do you come out to Steenberg for thatch treatment?
Yes. Steenberg is part of our regular Southern Suburbs route, along with Retreat, Lavender Hill, Tokai, Kirstenhof. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
Do you service both sides of Steenberg?
Yes, we cover the residential area near Retreat and the estates on the mountain side. Treatments are tailored to each type of home.
Do I need to move out?
Usually not. We will tell you which rooms to keep clear during treatment and for how long.
Why do I find scorpions in my Steenberg estate home?
Homes near the mountain border fynbos and rocky ground where scorpions live. Sealing gaps under doors and clearing rock piles near the house helps.
