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 crawling insects here
German cockroaches settle in kitchens and move through shared walls, and ants are common in sandy yards. Fishmoths show up where clothes and boxes are stored.
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.
Tell-tale signs
- Fresh webs reappear in the same corners, window frames and eaves within days of being brushed down.
- Outside lights draw a cloud of moths and midges each night with webs built right around them.
- Untidy, tangled webs show up under outdoor chairs, in the meter box or around the pool pump.
- Egg sacs, often round and papery or spiky in the case of the brown button spider, are stuck to brickwork or furniture.
- Cast skins and dead insects collect along skirting boards and in the backs of cupboards.
- You keep finding small pale spiders in bedding, curtains or clothing that has been left folded.
A note from the field
The first thing a technician checks is not the spider but what it is eating. Bright security lights, damp areas with lots of small insects, or an ant trail along the wall will keep drawing spiders in no matter how often you spray.
How we handle spider control in Delft
We start by identifying the species, because a rain spider on the wall and a nest of button spiders by the jungle gym call for very different responses. Webs and egg sacs are removed by hand or vacuum first, which takes out a surprising amount of the next generation. We then apply a residual spray or a fine insecticide dust into the places spiders actually live: roof voids, behind fitted units, wall cavities, garages, eaves and window reveals, keeping it away from where children and pets play. Where insects are drawing the spiders in, we treat or advise on that food source too, because spiders follow their prey. Finally we point out gaps around doors, vents and pipes that need sealing.

Prevention that actually works
- Swap white outdoor bulbs for warm yellow or LED ones so fewer insects gather, which means fewer spiders setting up around your doors.
- Pull beds slightly away from the wall and keep bedding off the floor to reduce night-time bites from sac spiders.
- Brush down webs regularly and vacuum the corners and the backs of cupboards, which gets rid of egg sacs before they hatch.
- Shake out shoes, gardening gloves and clothes that have been left on the floor or in the garage before you put them on.
- Fit fine mesh to vents and seal the gaps around pipes and under doors with sealant or brush strips.
How much will it cost?
The cost depends mainly on the size of the property and how many outbuildings, garages and roof spaces need treatment. A house with a heavy insect problem feeding the spiders takes more work than one with a few webs in the corners. We give a free quote after a quick look or a WhatsApp photo, and contract clients get spiders covered as part of their routine visits.
Honestly, a broom, a vacuum and better outdoor lighting solve a lot of spider complaints without any chemical at all. Supermarket aerosols kill the spider you spray but do little for the ones in the roof void or wall cavity. If you suspect violin or button spiders, or you are seeing bites, get it looked at properly rather than guessing.
Questions we get asked in Delft
How long does a spider treatment last?
A residual treatment keeps working for a good while, and our treatments carry a minimum 3-month guarantee. New spiders can still wander in from the garden, which is why sealing gaps and fixing outdoor lighting matters.
Is the rain spider in my house dangerous?
Not really. Rain spiders are big and fast but rarely bite, and the bite is painful rather than dangerous; the kindest option is to catch it under a container and put it outside.
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.
What should I do if someone is bitten?
Clean the bite, keep the spider if you can safely do so for identification, and see a doctor, especially for a suspected button or violin spider bite. Do not rely on a pest controller for medical advice.
Do you come out to Delft for spider control?
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.
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.
