Tamboerskloof climbs steeply up the slopes of Lion's Head and Signal Hill above Kloof Street.
Tamboerskloof: what drives stored product pests here
Delis and restaurants on Kloof Street need regular checks for pantry moths and weevils. At home, flour and spices in old pantries are the usual culprits.
Victorian and Edwardian homes with wooden floors, sash windows and pressed-ceiling interiors sit beside newer apartment blocks and converted guest houses. Kloof Street's restaurants and shops add a busy commercial layer at the bottom of the suburb.
From the technician
Weevils develop inside the grain, which is why sprays do not work. The only real solution is to remove the infested food and protect the rest.
For landlords and tenants, weevils are almost always a food storage issue rather than a building issue, so they are usually the occupant's to deal with.
Tell-tale signs
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.
How we handle weevil control in Tamboerskloof
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.
- Confirm it is a weevil
A WhatsApp photo is often enough to tell a rice weevil from a flour beetle or a seed beetle, which affects where we look.
- Inspect all grain products
Rice, maize meal, samp, pasta, flour, beans, lentils and birdseed are opened and checked.
- Remove infested stock
Anything with live weevils, holes or dust is bagged and taken out of the kitchen or storeroom.
- Clean and treat
Shelving and cracks are vacuumed and given a targeted treatment where adult weevils hide.
- Monitor
Traps are placed to catch any survivors and to show whether the problem is resolved.
- Report and storage advice
You get a report and practical advice on sealed containers, freezing and stock rotation.
Keeping them out afterwards
- Keep grain away from the warmest spots in the kitchen, like the cupboard above the oven or next to the geyser.
- 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.
- Freeze new bags of rice or flour for three or four days before you store them if weevils have been a problem before.
- Store rice, maize meal and samp in airtight glass or thick plastic containers, because weevils chew through thin plastic bags and cardboard.
What affects the price
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.
Weevils breed much faster in warm conditions, so infestations that began unnoticed in winter usually show up between November and March. A rice weevil can go from egg to adult in about a month in summer heat, compared with several months in a cold Cape winter. Warm, humid pantries can keep them active all year.
Frequently asked questions
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.
Do bay leaves keep weevils away?
There is little evidence they work. Airtight containers and freezing new stock are far more reliable.
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.
Can I eat rice that had weevils in it?
It is not known to be harmful, but the grain is contaminated with insects and droppings, and we would throw it away.
Do you come out to Tamboerskloof for weevil control?
Yes. Tamboerskloof is part of our regular City Bowl & Atlantic Seaboard route, along with Gardens, Higgovale, Bo-Kaap, Schotsche Kloof. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
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.
