Know what you are dealing with
The European paper wasp, Polistes dominula, is the main problem species in Cape Town and the Boland, an invasive wasp that has spread fast through suburbs and farms in the Western Cape. It builds open, grey, comb-like nests under eaves, in window frames, inside gate posts, in letterboxes and under garden furniture, often in large numbers on a single property. South Africa also has native paper wasps such as Belonogaster species, whose nests look similar but tend to be smaller and less aggressive, and solitary mud dauber wasps that build mud cells and very rarely sting. The invasive Polistes competes with native insects and feeds on caterpillars and other invertebrates, and it also takes fruit in orchards and vineyards. Identification matters, because a single mud dauber does not need the same response as a street full of Polistes nests.
Myths, mistakes and lesser-known facts
If you have children or a dog that spends the day in the garden, check the jungle gym, the dog kennel and the underside of outdoor tables. Those are common hidden nest sites.
For body corporates and estate managers, one property owner removing nests while the neighbours do nothing just means wasps move next door. A coordinated plan works far better.
Wasps are attracted to water as much as food. A dripping tap or a pool edge can keep them coming back to a garden all summer.
Warning signs
Tick every sign you have noticed. It takes ten seconds.
Why it matters: Paper wasps sting when their nest is disturbed, and they can sting more than once, which is a real danger for anyone with a sting allergy and a misery for children playing outside. Nests in letterboxes, gate motors and garden furniture lead to stings because people touch them without seeing the nest. On farms and in the Winelands, Polistes damages soft fruit and grapes and gets in the way of harvest work. Because the species is invasive, every nest left alone produces new queens that start more nests nearby the following spring.
Can you do it yourself?
Knocking down a tiny new nest in spring is a reasonable DIY job if you are not allergic and you do it at dusk. Once a nest is bigger than your palm, or it is high up, inside a wall or near where children play, we would rather you left it to us, because most of the stings we hear about come from people tackling a big nest with a can of spray in daylight. And if wasps keep coming back every year, the problem is the property and the neighbourhood, not one nest.
Seasonal pattern
Queens come out of hiding as the weather warms in late August and September and start small nests on their own, which is the cheapest and safest time to deal with them. Colonies grow quickly through the hot, dry summer and reach their biggest and most defensive in February and March. With the first winter rains and cold fronts the colonies die off, and only the new queens survive to start again next spring.
Prevention checklist
- Walk around the house once a week from September and knock down any nest smaller than a coin with a long pole, at dusk, wearing long sleeves.
- Pick up fallen fruit and grapes promptly, because ripe fruit draws foraging wasps in late summer.
- Fix dripping taps and irrigation leaks, since wasps need a steady water source to build nests.
- Seal holes in hollow gate posts, steel poles and roller door channels with a cap or sealant.
- Keep outdoor bins closed and clean up after a braai, as wasps scavenge meat and sweet drinks.
- Check garden furniture, umbrellas and the inside of letterboxes before using them in summer.
What affects the price
Wasp control is priced on how many nests there are, how high and hard to reach they are, and whether you want a once-off treatment or ongoing visits through the season. A house with one or two nests at ladder height is a straightforward job, while farms, estates and complexes with nests spread over many buildings take longer. For properties that get wasps every year, a seasonal plan usually saves money compared to repeated call-outs, and the quote is free.
Frequently asked questions
Which areas do you cover for wasp control?
All of Cape Town and the Boland: 133 suburbs from Atlantis and Melkbosstrand to Simon's Town, Khayelitsha and Gordon's Bay. We are based in Brackenfell.
Can I deal with wasps myself?
Knocking down a tiny new nest in spring is a reasonable DIY job if you are not allergic and you do it at dusk. Once a nest is bigger than your palm, or it is high up, inside a wall or near where children play, we would rather you left it to us, because most of the stings we hear about come from people tackling a big nest with a can of spray in daylight.

How do I get a quote?
Call 021 012 5825 or send us a photo on WhatsApp. Quotes are free and we will tell you what you are dealing with.
When is the best time to treat wasps?
Early spring, when nests are small and only the queen is there. Later in summer the same nest can hold dozens of wasps and is far more likely to cause stings.
Do wasp traps work?
They catch some foraging wasps, but they rarely reduce the number of nests and can attract more wasps to your garden. Finding and treating the nests works much better.
Can you look after a whole estate or farm?
Yes. We do scheduled wasp checks for estates, complexes and farms through the season, with a report after each visit.
How quickly can you remove a wasp nest?
Our average turnaround is around 48 hours, depending on the season. If a nest is right by a door or someone is allergic, tell us, and we can arrange an after-hours or weekend visit on request.
Is it safe to spray a nest myself?
It is risky with a large nest, because a can of spray rarely kills the whole colony and the survivors get very defensive. Small nests at dusk are another story.
What if the nest is inside a wall?
We treat it through the entrance hole with a dust, wait for activity to stop and only then seal the hole, so the wasps are not forced inside the house.
