Strand is a beach town first, so a lot of our work follows the holiday calendar. Flats on Beach Road sit empty for months, then fill up over December, and pests that moved in quietly during the off-season suddenly become everyone's problem.
Timber pests around Strand
Older inland homes with timber roof trusses can carry wood borer, and the beetle certificate needed on a property sale is often when it gets found. Coastal flats rarely have a timber problem beyond the odd built-in cupboard.
Along the beachfront you get blocks of holiday and retirement flats, many with shared refuse rooms and long service ducts that let cockroaches travel between units. Further back from the sea the streets are older freestanding homes and townhouse complexes, plus a busy commercial strip with takeaways and small supermarkets. Lock-up-and-go flats are the tricky ones, because nobody notices droppings or a fishmoth problem until the owner arrives for the season.
A note from the field
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.
If you have a pool or pond next to a lapa, mention it. We plan treatments under thatch so nothing drifts into the water.
Signs to look for
- Insects such as cockroaches or spiders falling from the ceiling.
- Birds pulling reed out of the roof or nesting under the eaves.
- Small round exit holes in the poles, especially in the paler sapwood.
- Rustling or scratching in the roof at night.
- 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.
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.

Keeping them out afterwards
- 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.
- 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.
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.
Can you stop gulls from nesting on our block's roof near the beach?
Yes. Bird netting, spikes and wire systems on the roof edges and plant areas make the building far less attractive, and it is best installed before the nesting season starts.
Do you come out to Strand for thatch treatment?
Yes. Strand is part of our regular Helderberg route, along with Somerset West, Gordon's Bay, Macassar, Helderberg. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
Can you treat a lapa or braai area?
Yes, lapas are often the easiest to treat because the whole structure is open underneath.
Why do I find cockroaches in my Strand holiday flat every time I come back?
Usually they are coming from neighbouring units or the shared refuse room, not starting in your flat. Treating your unit helps, but the best results come when the body corporate treats the ducts and bin areas at the same time.
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.
