Tokai sits at the foot of the Constantiaberg, with Tokai Forest and the Table Mountain National Park right behind it. Large plots, big gardens and that green backdrop mean wildlife and pests come with the territory.
Biting insects in Tokai: what we see
Fleas come in with pets that roam big gardens. Mosquito bites in summer are more common near ponds and water features.
Tokai Forest and the mountain slopes bring cool, damp air and lots of leaf litter. Winter rainfall is high here compared to the Cape Flats, so damp-loving insects thrive. Streams run down from the mountain, and many gardens have water features or ponds.
Homes here are mostly spacious, freestanding houses on generous plots, with pools, outbuildings and established trees. Some older homes have thatched roofs or large timber features, and there are a number of security estates and townhouse complexes. Garden cottages and staff quarters add more spaces for pests to hide.
Rats and mice from the forest edge and big gardens are a common issue. Timber pests matter in thatched and older homes. Ants, spiders, fishmoths and the odd scorpion are frequent, and wasps nest in large gardens in summer.
From the technician
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.
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.
Tell-tale signs
- Small dark mosquitoes resting on shaded walls, under the eaves or behind curtains during the day.
- A high-pitched whine near your ear just as you fall asleep.
- 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.
- Itchy, raised bites on arms, face and feet that were left outside the covers.
In the Western Cape, mosquitoes are mainly a nuisance and are not a malaria risk, but the bites can cause swelling and itching that is worse in children and some adults. Scratched bites can become infected, and constant night-time biting leads to poor sleep for the whole household. For hospitality businesses, restaurants with outdoor seating and wedding venues, mosquitoes in the evening can directly affect guest comfort and reviews.
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.

Stopping a repeat visit
- Clean gutters after winter so they do not hold water through summer.
- Fit mosquito screens to bedroom windows and use a net over cots in summer.
- Stock ornamental ponds with small fish that eat larvae, and keep water features running.
- 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.
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 Tokai
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.
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.
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.
Do rats come into Tokai homes from the forest?
Yes, the forest edge and big gardens support rodents that move into homes when it gets cold and wet. Sealing roof gaps and removing outdoor food sources makes your home far less attractive.
Do you come out to Tokai for mosquito control?
Yes. Tokai is part of our regular Southern Suburbs route, along with Bergvliet, Kirstenhof, Constantia, Steenberg. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
How often should a thatched roof in Tokai be checked for beetles?
Once a year is a good habit, and definitely before you sell. Early treatment is much simpler than dealing with heavy damage later.
