Bishopscourt is a very green suburb of large homes, ambassadors' residences and old trees right beside Kirstenbosch. Pest work here is often about big properties with outbuildings, staff quarters, pools and heavy garden growth, rather than anything to do with density.
Biting insects in Bishopscourt: what we see
Bird mites are the surprise one here: when a nest in the eaves is abandoned, the mites wander into bedrooms looking for a meal. Fleas follow dogs that roam the big gardens.
Bishopscourt sits on the slopes below Table Mountain, with Kirstenbosch and the national park right next door. The Liesbeek River starts nearby, and winter rain keeps everything wet and lush. Big oaks, pines and fruit trees feed rodents and squirrels.
Roof rats and grey squirrels in ceilings are common, and mole rats tunnel through lawns. Wasps nest in eaves and hedges, and ants trail in from the gardens. Timber borer and thatch pests are a real consideration on these properties.
From the technician
When our technician arrives, the first thing they check is the gutters. Blocked gutters full of leaves hold water for weeks after rain and are one of the most overlooked breeding sites in Cape Town homes.
Children tend to react more strongly to mosquito bites, with bigger swelling and more scratching. A net over the cot and screens on the bedroom window are simple, effective protection.
What gives them away
- Itchy, raised bites on arms, face and feet that were left outside the covers.
- Wriggling larvae, sometimes called wigglers, in pond edges, buckets, bird baths or pool covers.
- Small dark mosquitoes resting on shaded walls, under the eaves or behind curtains during the day.
- Day-time bites on the ankles while sitting in the garden, which points to Aedes breeding nearby.
- Swarms in the evening near a water feature, drain or neglected pool.
How we handle mosquito control in Bishopscourt
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.
- 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.
- Stock ornamental ponds with small fish that eat larvae, and keep water features running.
- Clean gutters after winter so they do not hold water through summer.
Pricing, honestly
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.
Mosquitoes start building up once the weather warms in October and peak from December to March, especially after a wet winter has filled ponds, vleis and gutters. Calm, humid evenings are the worst, while the strong south-easter actually keeps them down on windy days. Numbers drop sharply when the cold, wet winter sets in from about May.
Frequently asked questions
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.
Should I worry about borer in my Bishopscourt thatch lapa?
It is worth checking, because thatch and timber in shady, damp spots can attract wood-boring beetles. A yearly inspection catches problems early and keeps the structure sound.
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.
Why are there so many mosquitoes this summer?
Usually because a wet winter left more standing water, or a breeding site has developed close by, such as a blocked gutter or an untreated pond.
Do you come out to Bishopscourt for mosquito control?
Yes. Bishopscourt is part of our regular Southern Suburbs route, along with Newlands, Claremont, Constantia, Kenilworth. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
Do the trees near Kirstenbosch bring squirrels into Bishopscourt roofs?
Yes, grey squirrels and roof rats use the tall trees as highways onto roofs. We trim access routes, seal gaps and treat roofs where needed.
