Zonnebloem covers much of what was District Six, between the city centre and Woodstock, with the CPUT campus at its centre. Today it is a mix of campus buildings, newer housing and open land, and that combination gives pests plenty of room.
Biting insects in Zonnebloem: what we see
Bed bugs are a real risk in student residences with frequent turnover. Fleas come with pets and rodents.
The area sits on the slope below Devil's Peak, with De Waal Drive and the Eastern Boulevard nearby. Open land attracts rodents and dumping, and winter rains turn some patches muddy. The South-Easter blows litter across the open spaces in summer.
The CPUT campus, student residences, schools, churches and mosques sit alongside newer housing developments and older homes. Open land left after the forced removals still surrounds parts of the area. Student residences and shared housing see a quick turnover of occupants, which can bring in bed bugs and cockroaches.
Rats from the open land and old drains are the main concern. German cockroaches and bed bugs show up in residences and shared housing. Pigeons roost on campus and institutional buildings.
Worth knowing
The south-easter is not all bad news. Mosquitoes struggle to fly in strong wind, so windy Cape Town days are often bite-free, and the worst nights come when the wind drops.
Signs to look for
- Day-time bites on the ankles while sitting in the garden, which points to Aedes breeding nearby.
- Wriggling larvae, sometimes called wigglers, in pond edges, buckets, bird baths or pool covers.
- Swarms in the evening near a water feature, drain or neglected pool.
- Small dark mosquitoes resting on shaded walls, under the eaves or behind curtains during the day.
- Itchy, raised bites on arms, face and feet that were left outside the covers.
- A high-pitched whine near your ear just as you fall asleep.
How the treatment works
Source reduction always comes first: we walk the property and find every place water collects, from gutters and drains to ponds, water features, plant saucers and covered pools, and tell you which ones to empty, fix or cover. Water that cannot be removed, such as ponds and drains, can be treated with a larvicide or insect growth regulator that stops larvae becoming adults. Adult mosquitoes rest in cool, shaded places during the day, so we apply a residual spray to the undersides of shrubs, hedges, eaves, patio ceilings and other resting areas. For events or heavy problems, ULV fogging can knock down adult numbers quickly, but it only works properly when combined with dealing with the breeding sites.
- Property walk
We check gutters, drains, ponds, pools, water features and containers for larvae.
- Remove or fix breeding sites
We show you what to empty, cover or repair, and clear what we can on the day.
- Treat remaining water
Ponds, drains and sumps that cannot be emptied are treated with a larvicide or growth regulator.
- Treat resting areas
A residual spray goes onto shaded foliage, eaves and patio areas where adults rest.
- Fogging if needed
ULV fogging is used for events or severe cases to reduce adult numbers quickly.
- Follow-up plan
We leave a report and agree whether follow-up visits through summer make sense.
Keeping them out afterwards
- Keep pool water circulating and treated, and drain the water that collects on top of pool covers.
- Fit mosquito screens to bedroom windows and use a net over cots in summer.
- Clean gutters after winter so they do not hold water through summer.
- Empty pot-plant saucers, buckets, bird baths and pet water bowls at least once a week, because larvae develop into adults in about a week in hot weather.
- Store old tyres, tins and containers under cover or throw them away.
How much will it cost?
Cost depends on the size of the property, how many breeding sites there are and whether larger water bodies such as ponds or drains need treating. A once-off treatment is priced differently from a programme of visits through the summer season. Fogging for an event is quoted on the size of the area, and the quote itself is free.
Most mosquito problems on a normal suburban property can be cut dramatically by the owner just by emptying standing water every week. Plug-in repellents and sprays help you sleep, but they do nothing about where the mosquitoes come from. Call a professional when the breeding site is something you cannot fix yourself, like a large pond, a blocked drain or a neighbouring property, or when you need numbers down for an event.
Questions we get asked in Zonnebloem
Can you treat a whole student residence in Zonnebloem for bed bugs?
Yes. We inspect, treat affected rooms and neighbouring ones, and give a post-treatment report, which helps residence managers keep track.
Why are there so many rats around the open land in Zonnebloem?
Open land with long grass, dumped waste and old drains gives rats food and shelter. Buildings nearby need sealed entry points and perimeter bait stations to keep them out.
How far do mosquitoes fly?
Most household mosquitoes do not fly far from where they bred, so the source is usually on your property or a neighbour's.
Do you come out to Zonnebloem for mosquito control?
Yes. Zonnebloem is part of our regular City Bowl & Atlantic Seaboard route, along with Walmer Estate, University Estate, Woodstock, Vredehoek. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
Can you treat before a wedding or function?
Yes. We usually inspect beforehand, deal with breeding sites and then fog or spray resting areas shortly before the event.
Is there a malaria risk in Cape Town?
No, the Western Cape is not a malaria area. Mosquitoes here are a nuisance and cause itchy bites, but the main concern is comfort and sleep.
