Simon's Town is a historic naval town on False Bay, with steep streets climbing the mountain behind St George's Street. Old buildings, the sea air and the mountain on the doorstep make for a very particular set of pest problems.
Biting insects in Simon's Town: what we see
Bed bugs travel in with guests at B&Bs and guesthouses, and fleas show up where pets live. Quick action between bookings keeps rooms open.
The town sits between False Bay and the mountains of Table Mountain National Park, with Boulders and its penguin colony on the southern side. Winters are wet and windy, and the South-Easter blows hard in summer. The mountain edge brings rodents, baboons and insects, and the sea air keeps buildings damp.
There are old stone and brick buildings from the naval history, Victorian cottages, guesthouses along the main road and newer homes on the slopes above. Many buildings have timber floors, roofs and joinery that have weathered for a long time. Guesthouses and restaurants serve a steady stream of visitors. Steep sites mean retaining walls and rockeries, which give rodents and spiders plenty of places to hide.
Rats and mice from the mountain edge and harbour are the main issue. Fishmoths and wood borer show up in old, damp buildings. Bed bugs are a risk in guesthouses, and gulls and pigeons are constant along the waterfront.
Tell-tale signs
- 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.
- 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.
- Wriggling larvae, sometimes called wigglers, in pond edges, buckets, bird baths or pool 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.
A note from the field
Restaurants and guest houses with outdoor areas lose evening trade when mosquitoes get bad. Treating resting areas and keeping water features maintained should be part of the summer routine.
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.
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
- Stock ornamental ponds with small fish that eat larvae, and keep water features running.
- 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.
- Clean gutters after winter so they do not hold water through summer.
What affects the price
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.
Frequently asked questions
Do you come out to Simon's Town for mosquito control?
Yes. Simon's Town is part of our regular South Peninsula route, along with Glencairn, Fish Hoek, Scarborough. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
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 rats in Simon's Town come from the harbour or the mountain?
Both. Homes near the waterfront tend to get rats from the harbour, while houses higher up get them from the mountain slopes.
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.
Can you treat old heritage buildings in Simon's Town without damaging them?
Yes, we choose methods that don't harm old timber, plaster or stonework, and we focus on proofing gaps carefully. We'll talk you through the plan before starting.
