Wasp nests in Tamboerskloof
Tamboerskloof's steep streets shelter many gardens from the worst of the South-Easter, which suits paper wasps. They build under the eaves and on the stoep ceilings of the old houses, in pergolas and creepers, and in the corners of small courtyards. Because so many homes open straight onto narrow pavements, a nest by a front door can sting people walking past, and guest house entrances need extra care.
We treat the nest, remove it once it's safe and check the neighbouring eaves and pergolas. Early spring is the easiest time, while nests are small, and we can come before guests are up.
What gives them away
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.
Worth knowing
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.
How the treatment works
For ongoing wasp control we combine nest treatment with prevention rather than coming out once a year to remove whatever has grown. Active nests are treated with an insecticidal dust or spray applied directly into the comb, usually early in the morning or late in the day when the wasps are on the nest, and the comb is taken down once the colony is dead. On properties with repeat problems we do a sweep in early spring to find and remove young founding nests while they are small, and we can apply a residual treatment to favourite nesting spots such as eaves and pergolas. We also look at what is drawing wasps in, like water points, fallen fruit and open bins, and give practical advice on fixing it. For farms, estates and complexes, scheduled visits through the wasp season keep numbers under control instead of letting them build up.

Prevention that actually works
- Keep outdoor bins closed and clean up after a braai, as wasps scavenge meat and sweet drinks.
- Seal holes in hollow gate posts, steel poles and roller door channels with a cap or sealant.
- Fix dripping taps and irrigation leaks, since wasps need a steady water source to build nests.
- Check garden furniture, umbrellas and the inside of letterboxes before using them in summer.
- Pick up fallen fruit and grapes promptly, because ripe fruit draws foraging wasps in late summer.
Pricing, honestly
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.
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.
Frequently asked questions
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.
When are wasps most active in Tamboerskloof?
From late spring to late summer, when nests are growing.
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.
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.
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.
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.
