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.
Stored product pests in Delft: what we see
Weevils in maize meal and rice are common at home. Spaza shops should have stock rooms checked regularly for weevils, cockroaches and mice.
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.
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.
From the technician
Freezing is underrated. A few days in the freezer kills eggs and larvae in flour, rice and grains without affecting the food.
Throwing out the infested packet but leaving the shelves as they are is a common mistake. Eggs and larvae sit in the crumbs in corners and shelf joints, ready to start again.
Tell-tale signs
- Pheromone traps or glue boards in a warehouse catch more beetles or moths each week.
- Flour has a greyish tint, a musty smell or moves slightly when you look closely.
- Silky webbing clumps cereal, nuts or pet food together, sometimes with small caterpillars inside.
- Insects collect in the folds of packaging or along the seams of sealed boxes and bags.
- Grains of rice or maize have tiny round exit holes, or the bag has fine dust at the bottom.
- Small moths flutter out when you open a cupboard, and rest on the ceiling at night.
What happens when we come out
The first and most important step is finding and removing every infested product, because no treatment works while the insects still have food. Shelves, cracks and crevices, and the gaps behind and under cupboards and racking are vacuumed out to remove spilt product and eggs. We then apply a targeted residual treatment into cracks and crevices, and an insect growth regulator where the pest is a moth or beetle that keeps cycling through. Pheromone traps for moths and beetles go in to monitor for survivors and new arrivals. In warehouses, mills and food factories, larger infestations of bulk commodities may need fumigation, which we plan and carry out separately under the right controls.

Keeping them out afterwards
- Buy dry goods in amounts you will use within a month or two, rather than letting big bags sit at the back of the cupboard.
- Move flour, rice, cereal, pasta and pet food into sealed glass or hard plastic containers as soon as you get them home.
- Put new bags of flour or grain in the freezer for a few days if you have had weevils before, which kills eggs inside.
- Store birdseed and pet food away from the kitchen, as these are common sources of pantry moths.
- In commercial stores, rotate stock on a first-in, first-out basis and keep pallets off walls so you can inspect behind them.
Pricing, honestly
For homes, the cost depends mostly on how big the pantry is and how far the insects have spread into other cupboards. For commercial sites, the size of the storage area, the type of commodity, the level of infestation and whether fumigation is needed all affect the price. Food businesses that need regular monitoring and audit paperwork are usually best on a service contract, and we quote free after an inspection.
In a home pantry, throwing out infested food, a thorough clean and sealed containers fixes most problems, and we will happily talk you through that over the phone. Spraying insecticide in a cupboard full of food is a bad idea, so please do not. Where you need a professional is when the insects keep returning after a clean-out, or when you have a commercial store, bakery or factory where losses and audits are at stake.
Stored Product Pest Control questions from Delft
What are pheromone traps?
Small sticky traps baited with a scent that attracts a specific moth or beetle. They show whether the insects are still around and help us measure how well the treatment worked.
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.
Do I have to throw everything away?
Throw away anything infested and anything open that is close to it. Unopened tins and sealed jars are generally fine once wiped down.
Do you come out to Delft for stored product pest 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.
Do you work in warehouses and food factories?
Yes. We do inspections, crack and crevice treatment, pheromone monitoring and scheduled visits, with reports you can use for food safety audits.
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.
