Elsies River is old, busy and tightly built, with Halt Road's shops, the railway line and the Epping industrial edge all within walking distance of people's front doors. When we come out here it is usually for rats or cockroaches, and the job tends to involve the whole block rather than one unit.
Elsies River: what drives biting insects here
Fleas from dogs and cats are the most common biting complaint. Bed bugs move with furniture and mattresses, and in flats they can walk between units along skirting boards and pipes.
The Elsieskraal River, which gave the area its name, runs in a concrete channel nearby, and like most canalised urban rivers it carries rubbish and rats. The railway reserve is another long, sheltered corridor for rodents. On the flat ground here, winter rain can sit in yards and blocked stormwater drains for days.
Rats come first, especially near the river channel, the railway and anywhere waste piles up. German cockroaches in flats and takeaway kitchens are the next biggest job. Fleas, flies and bed bugs make up most of the rest.
How to tell you have a problem
- A high-pitched whine near your ear just as you fall asleep.
- 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.
- Itchy, raised bites on arms, face and feet that were left outside the covers.
Something most people miss
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.
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.
Our process, step by step
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.

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.
- 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 Elsies River
Do you come out to Elsies River for mosquito control?
Yes. Elsies River is part of our regular Cape Flats route, along with Goodwood, Parow, Bishop Lavis, Epping. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
Do the rats in Elsies River come from the river canal?
Many do. The Elsieskraal channel and the railway reserve both give rats shelter and a route into nearby yards, so homes close to them see more activity.
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.
Can you treat a whole block of flats in Elsies River for cockroaches?
Yes, and it is the approach that works best, because roaches travel through shared pipes and ducts. We can schedule the units together and leave a post-treatment report.
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.
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.
