Delft is one of Cape Town's more densely built areas, with families living close together and many extra rooms built onto the back of houses. Most calls here are about rats, cockroaches and fleas, and the best results come from treating a few neighbouring homes together.
Delft: what drives timber pests here
Borer is seldom a problem in the brick houses, but the timber frames of wendy houses and backyard rooms can be attacked. A beetle certificate may be needed if a house is sold.
Housing is mostly government-built family homes on small plots, many extended with backyard rooms, wendy houses and informal structures. Homes stand close together, and extensions built with corrugated sheeting often leave gaps at the roofline. More people and more food in a small space gives pests plenty to work with. Spaza shops run from homes add stock rooms to the picture.
Delft lies on flat, sandy ground near Cape Town International Airport and the N2. The South-Easter blows sand and litter across open ground all summer, and in winter some streets become waterlogged when stormwater drains block. Vacant land around the edges gives rodents cover.
Rats are the main concern, feeding on waste and burrowing under structures in the soft sand. Cockroaches spread easily through shared walls and kitchens. Fleas with dogs and cats are a regular problem, and flies peak around bins and dumping spots in summer.
Tell-tale signs
- Insects such as cockroaches or spiders falling from the ceiling.
- Tunnels or loose patches in the thatch where rodents have been moving.
- Droppings on beams or along the top of walls under the thatch.
- 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.
Worth knowing
If you have a pool or pond next to a lapa, mention it. We plan treatments under thatch so nothing drifts into the water.
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 Delft
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.

Prevention that actually works
- 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.
- 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.
- Keep trees and creepers trimmed back from the thatch so rodents cannot step straight onto the roof.
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.
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.
Questions we get asked in Delft
Is there a guarantee?
Our treatments carry a minimum 3-month guarantee, and the report records exactly what was treated.
My children are getting bites at night in Delft. Is it fleas or bed bugs?
Bites around the ankles usually point to fleas, while rows of bites on arms, neck or back point to bed bugs. WhatsApp us a photo of any insect you find and we will help identify it.
Do you come out to Delft for thatch treatment?
Yes. Delft is part of our regular Cape Flats route, along with Belhar, Bishop Lavis, Kuils River, Nyanga. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
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.
Can you treat a lapa or braai area?
Yes, lapas are often the easiest to treat because the whole structure is open underneath.
Can you treat my whole row of houses in Delft for rats at once?
Yes, and it works better that way. Send us the addresses and we will give a free quote for treating the properties together.
