Athlone is busy, built-up and full of small businesses, so a lot of our work here is about stopping pests moving between homes, shops and takeaways that share the same blocks.
Athlone: what drives stored product pests here
The many spaza shops, bakeries and halaal takeaways mean stored product pests like flour beetles and pantry moths are a real issue in bulk stock. At home, maize meal and rice bought in large bags are where weevils usually show up.
Most homes are older semi-detached and freestanding brick houses, plus council flats in places like Kewtown and Bridgetown.
Worth knowing
A technician's first check is the backs of cupboards and the containers people forget, like a jar of popcorn kernels or a bag of birdseed in the garage.
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.
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.
Our process, step by step
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.

Stopping a repeat visit
- Use older stock first and avoid topping up a container with new grain on top of old.
- On farms and smallholdings, clean out silos and bins completely before refilling with new harvest.
- Keep grain away from the warmest spots in the kitchen, like the cupboard above the oven or next to the geyser.
- Store rice, maize meal and samp in airtight glass or thick plastic containers, because weevils chew through thin plastic bags and cardboard.
- 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
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.
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.
Do you come out to Athlone for weevil control?
Yes. Athlone is part of our regular Cape Flats route, along with Crawford, Rondebosch East, Lansdowne, Langa. 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.
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.
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.
