The Cape Flats is the wide, flat sandy plain that stretches from the mountain towards False Bay, home to a huge share of Cape Town's people. Pest problems differ from suburb to suburb, but the common thread is sandy ground, a high water table in winter and a lot of homes built close together.

Cape Flats: what drives stored product pests here
Families who buy maize meal, samp and rice in big bags often find weevils by the bottom of the bag. Spaza shops and small bakeries benefit from routine checks on flour and grain stock.
Housing ranges from older council semis and flat blocks to RDP homes, backyard rooms and informal structures. Waste collection and stormwater that cannot cope after heavy rain make the job harder, which is why community-wide approaches work best.
The Flats were once dunes and wetlands, and in winter the water table rises, flooding yards and low streets. In summer the South-Easter blows sand and litter across the open land.
How to tell you have a problem
Tick every sign you have noticed. It takes ten seconds.
Why it matters: Weevils are not known to bite or carry disease, but they ruin food, and the larvae inside the grain mean you cannot simply sieve them out. Infested stock has to be thrown away, which is a real cost for bakeries, restaurants, food distributors and farms with stored maize. In bulk storage, weevil activity creates heat and moisture pockets that encourage mould and further spoilage. For food businesses, weevils found by a customer or an auditor can damage trust very quickly.
A note from the field
Freezing is a simple trick that most people do not know. A few days in the freezer kills weevil eggs and larvae hiding inside the grains.
Sealed containers protect your other food from weevils, but they also contain an infestation if you buy a bad bag, so you only lose that one container.
How we handle weevil control in Cape Flats
Weevils develop inside the grain, so no surface spray can reach them while they are still in the kernel; removing infested food is the main treatment. We inspect every grain, pulse and cereal product, separate what is infested, and bag it for disposal. Shelves, cupboards and the gaps around them are vacuumed and cleaned, and we apply a targeted crack and crevice treatment where weevils are sheltering, keeping it well away from open food. For commercial stores and farm silos with heavy infestations of bulk grain, fumigation may be the only practical option, and we plan that as a separate job. Pheromone or food-baited traps are then used to check that numbers have dropped.

Keeping them out afterwards
- On farms and smallholdings, clean out silos and bins completely before refilling with new harvest.
- Use older stock first and avoid topping up a container with new grain on top of old.
- Check dried beans and lentils for small round holes before putting them in the cupboard.
- Keep grain away from the warmest spots in the kitchen, like the cupboard above the oven or next to the geyser.
- Freeze new bags of rice or flour for three or four days before you store them if weevils have been a problem before.
Pricing, honestly
For a home, the price mostly depends on how many cupboards are involved and whether the weevils have spread into other rooms. For businesses and farms, the volume of stored grain, how it is stored and whether fumigation is needed are the big factors. We quote for free, and food businesses with ongoing risk often prefer a contract with regular monitoring.
For a weevil problem in a home kitchen, a ruthless clean-out and sealed containers solve it most of the time, and you probably do not need us. Where it gets harder is when you keep finding weevils weeks later, which usually means one forgotten source, or when there is a lot of stored grain at stake. Do not bother with insecticide sprays in the pantry; they do nothing to the larvae inside the grain.
Frequently asked questions
Do bay leaves keep weevils away?
There is little evidence they work. Airtight containers and freezing new stock are far more reliable.
How did weevils get into my sealed bag of rice?
The eggs were most likely already inside the grains when you bought it. Female weevils lay eggs inside individual kernels, so the bag can look perfect from the outside.
Can you treat weevils in a silo or warehouse?
Yes. Larger stores may need fumigation or regular monitoring, and we will inspect and quote for the right approach.
Do you come out to Cape Flats for weevil control?
Yes. Cape Flats is part of our regular Cape Flats route, along with Mitchells Plain, Khayelitsha, Gugulethu, Athlone. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
Are the weevils in my beans the same as in my rice?
No. Bean weevils are seed beetles that only attack pulses, while rice and maize weevils attack grain, but the clean-out and storage advice is much the same.
Will weevils spread to the rest of the house?
Adults wander, so you may see them on walls and counters, but they only breed where there is grain or seed. Clearing the food source stops them.
