Fresnaye climbs the slopes above Sea Point toward Lion's Head, all steep streets, big houses and apartment blocks with sea views. Most calls here are about rats in roofs, ants in kitchens and pigeons on balconies.
Biting insects around Fresnaye
Fleas come with pets, and bird mites appear when pigeons nest on balconies or under roofs.
Fresnaye runs up the lower slopes of Lion's Head and Signal Hill, with fynbos and greenbelt directly above many homes. The South-Easter can be fierce, and winter storms hit straight off the Atlantic. Water runs down the slopes in winter, and rodents move down with the weather.
Homes range from large modern houses with flat roofs, pools and glass to older double-storey homes and blocks of flats. Many are built into the slope with retaining walls, basements and garden terraces, which create plenty of hidden voids. Flat roofs and roof gardens attract pigeons and gulls. Staff quarters, garages and pool rooms add more places to check.
Roof rats coming down from the mountain slopes are the main issue. Argentine ants, fishmoths and paper wasps are common, and pigeons and gulls cause trouble on balconies and flat roofs.
A note from the field
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.
Electric bug zappers attract plenty of insects, but studies have shown that very few of them are mosquitoes. Screens and source reduction do far more.
Signs to look for
- 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.
- Swarms in the evening near a water feature, drain or neglected pool.
- A high-pitched whine near your ear just as you fall asleep.
- Day-time bites on the ankles while sitting in the garden, which points to Aedes breeding nearby.
How we handle mosquito control in Fresnaye
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.
Stopping a repeat visit
- Fit mosquito screens to bedroom windows and use a net over cots in summer.
- Keep pool water circulating and treated, and drain the water that collects on top of pool covers.
- Store old tyres, tins and containers under cover or throw them away.
- 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.
- Stock ornamental ponds with small fish that eat larvae, and keep water features running.
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.
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.
Questions we get asked in Fresnaye
Do you come out to Fresnaye for mosquito control?
Yes. Fresnaye is part of our regular City Bowl & Atlantic Seaboard route, along with Sea Point, Bantry Bay, Clifton, Three Anchor Bay. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
Does fogging get rid of mosquitoes?
Fogging kills adults that are flying at the time, but new ones will hatch from any untreated water. It works best as part of a plan that deals with breeding sites.
Do the rats in Fresnaye come down from Lion's Head?
Many do, especially in winter. Homes on the upper streets see the most activity, and cutting back creepers and sealing roof gaps makes a big difference.
How do I stop pigeons nesting on my Fresnaye balcony?
Netting the balcony or fitting spikes on ledges stops them landing. Clearing any old nests first is important to get rid of bird mites.
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.
Are the treatments safe for fish in my pond?
We choose larvicides suitable for the situation and will tell you if a product is not appropriate for a fish pond. In many cases, fish themselves are the best control.
