Constantia means big plots, old oaks, vineyards and horses, so pest control here is often as much about the garden and outbuildings as the house itself. Squirrels in the roof, rats around the stables and wasps in the hedges are everyday conversations in the valley.
Stored product pests around Constantia
Horse feed, chicken feed and bulk dog food attract weevils, grain moths and mice. Restaurants and tasting rooms in the valley also need their dry stores checked regularly.
Many homes are large, older properties on generous stands, some Cape Dutch in style with thatched roofs, others modern with big glass walls and pool decks. Staff cottages, garages, stables and pool houses all add extra buildings that need checking. Thatch and exposed beams give rodents and borer beetles places that are hard to reach once they're established. The newer security estates have neater gardens but still back straight onto greenbelts.
The valley climbs up to the Constantiaberg and the edge of Table Mountain National Park, with wine farms such as Groot Constantia and Klein Constantia on the slopes. It gets noticeably more winter rain than most of the city, so gardens stay lush and soil stays damp well into spring. Greenbelts and small streams thread through the suburb, and the oaks drop enough acorns to feed a healthy squirrel population. Summer afternoons in the vineyards turn warm and still, which wasps love.
What gives them away
- Silky webbing clumps cereal, nuts or pet food together, sometimes with small caterpillars inside.
- 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.
- Insects collect in the folds of packaging or along the seams of sealed boxes and bags.
- Flour has a greyish tint, a musty smell or moves slightly when you look closely.
Something most people miss
Freezing is underrated. A few days in the freezer kills eggs and larvae in flour, rice and grains without affecting the food.
How we handle stored product pest control in Constantia
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.

Stopping a repeat visit
- 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.
- 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.
- Put new bags of flour or grain in the freezer for a few days if you have had weevils before, which kills eggs inside.
- Move flour, rice, cereal, pasta and pet food into sealed glass or hard plastic containers as soon as you get them home.
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.
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.
Frequently asked questions
Can you stop squirrels getting into my roof in Constantia?
Yes, but the lasting fix is physical. We find where they are getting in, usually a fascia gap or loose ridge tile next to an oak branch, and advise on sealing it once the roof is empty; cutting branches back from the roof helps a lot.
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.
Do you come out to Constantia for stored product pest control?
Yes. Constantia is part of our regular Southern Suburbs route, along with Bergvliet, Tokai, Plumstead, Diep River. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
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.
Does a thatched roof in Constantia need special treatment for borer?
The grass itself is not what borers are after, but the poles and battens holding it up can be. We inspect the visible timber for fresh holes and dust and treat only if there is active infestation.
Are these insects harmful if I eat them by accident?
They are not known to be dangerous in small amounts, but infested food is contaminated and should not be eaten or sold.
