Electric City is a tight grid of family homes on the Blue Downs side of the Cape Flats, where most yards hold a main house, a backyard room and a washing line within a few metres of the boundary wall. A rat problem here is rarely one household's problem, so we usually end up talking to the neighbours as well.
Stored product pests in Electric City: what we see
Bulk bags of maize meal, rice and flour bought at month-end are where weevils turn up, often weeks later. Spaza shops with stock stored in back rooms benefit from regular checks for both weevils and mice.
The original houses are small brick units, and over the years most have grown sideways and backwards with extra rooms, carports and wendy houses. Every add-on leaves a join between old and new roof sheeting, and those joins are where roof rats and pigeons find their way in. Wendy houses sitting straight on sand give rats a dry floor to tunnel beneath. With walls almost touching, a cockroach colony in one kitchen does not take long to reach the next.
This is flat, deep Cape Flats sand, the kind that drains fast in summer and then turns soggy in low spots once the winter fronts arrive. Summer wind lifts litter and sand into corners against walls, which is exactly where rats like to dig. Open veld strips and stormwater ponds on the edges of the Blue Downs area give rodents somewhere to live between raids on the houses.
What gives them away
- Flour has a greyish tint, a musty smell or moves slightly when you look closely.
- Small moths flutter out when you open a cupboard, and rest on the ceiling at night.
- Small brown or reddish beetles walk along pantry shelves or across the kitchen counter.
- Pheromone traps or glue boards in a warehouse catch more beetles or moths each week.
- Insects collect in the folds of packaging or along the seams of sealed boxes and bags.
- Silky webbing clumps cereal, nuts or pet food together, sometimes with small caterpillars inside.
Worth knowing
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.
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
- Move flour, rice, cereal, pasta and pet food into sealed glass or hard plastic containers as soon as you get them home.
- Wipe and vacuum pantry shelves when you restock, paying attention to corners and the gaps behind shelf supports.
- In commercial stores, rotate stock on a first-in, first-out basis and keep pallets off walls so you can inspect behind them.
- Store birdseed and pet food away from the kitchen, as these are common sources of pantry moths.
- 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.
How much will it cost?
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.
Stored product insects breed faster in warm weather, so infestations that started quietly in winter often become obvious from November through to March. In Cape Town's dry summers, warm pantries next to ovens and geysers are particular hot spots. In heated warehouses and bakeries the problem can carry on all year.
Questions we get asked in Electric City
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.
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 I spray inside the pantry?
We would not recommend it. A thorough clean-out and sealed storage do more, and any residual treatment should be targeted into cracks, not sprayed over shelves that hold food.
Why do the rats keep coming back to my Electric City yard after I bait?
Usually because the neighbouring yards are untreated, so new rats move into the space yours left. Treating a few adjoining homes at once breaks that cycle.
Do you come out to Electric City for stored product pest control?
Yes. Electric City is part of our regular Cape Flats route, along with Kuils River, Delft, Belhar. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
Is it rats or mice in my ceiling in Electric City?
Rat droppings are about the size of a raisin and mouse droppings look like grains of rice. WhatsApp us a photo and we will tell you which you are dealing with.
