Bonteheuwel is a close-knit, densely built suburb boxed in by the railway line, the Epping industrial area and busy roads. Pest problems here mostly come down to shared walls, backyard rooms and drains that struggle in winter.
Bonteheuwel: what drives timber pests here
Wood borer shows up in roof timbers and old built-in cupboards where roofs have leaked over the years. If you are selling or refinancing, the bank may ask for a beetle certificate.
Rows of semi-detached council houses and three-storey flat blocks make up most of Bonteheuwel, and many families have added Wendy houses or brick rooms at the back. Every shared wall and joined roof is a route for mice and German cockroaches, so one neighbour's problem soon becomes the next one's. The flats have communal stairwells and refuse points where rats feed at night.
It is flat, sandy Cape Flats ground, so winter downpours sit in yards and back up drains for days. The Epping industrial area next door has warehouses and food plants, and rats move freely between the two. Summer brings the South-Easter, which blows litter against walls and into corners.
Rats and German cockroaches are what people ask us about most. Fleas and bed bugs follow, because houses are full and pets live close to people. Flies around refuse points and mosquitoes after the winter floods are seasonal.
Signs to look for
- Tunnels or loose patches in the thatch where rodents have been moving.
- Small round exit holes in the poles, especially in the paler sapwood.
- Insects such as cockroaches or spiders falling from the ceiling.
- 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.
Something most people miss
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 electrical wiring in the roof inspected regularly, especially if you have had rodents.
- Do not store firewood or boxes against the walls under the thatch, as they give insects and rodents cover.
- Ask your thatcher to check the poles and laths for borer whenever the roof is being repaired or re-combed.
- Fit bird netting or wire at the eaves if birds keep pulling reed or nesting there.
- Have open thatch ceilings in lapas and lodges checked once a year, since problems are easy to see early.
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 Bonteheuwel
Do rats in Bonteheuwel come from the Epping industrial area?
Some do, since warehouses and food plants nearby give them food and shelter. Most, though, live along the railway line and around refuse points, so treating close to home matters most.
Can you treat a whole block of flats in Bonteheuwel for cockroaches?
Yes, and that is the best approach, because cockroaches move along shared pipes and walls. Treating every unit at once gives a much longer-lasting result.
Can you treat a lapa or braai area?
Yes, lapas are often the easiest to treat because the whole structure is open underneath.
Will the treatment damage my thatch?
No. We treat the timbers directly and keep any treatment of the thatch itself light and targeted.
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.
Do you come out to Bonteheuwel for thatch treatment?
Yes. Bonteheuwel is part of our regular Cape Flats route, along with Langa, Bishop Lavis, Epping, Elsies River. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
