Firgrove is a small, quiet spot on the Somerset West side of the Helderberg, with a country feel and a lot of open land around it. People here mostly call us about mice from the fields, flies around animals and wasps in the sheds.
The local picture in Firgrove
Fleas come in with dogs and cats, and bird mites can appear when doves or pigeons have nested in a roof.
Farmland and vineyards surround the area, with the Helderberg and the Hottentots Holland mountains on the skyline. The South-Easter blows strongly through summer, and winters are wet and chilly. When fields are ploughed or harvested, the rodents living in them look for new homes.
You get a mix of older village houses, smallholdings with sheds and stables, and some newer homes on larger plots. Smallholdings often keep animal feed, poultry and compost, which is a standing invitation to rodents. Older homes and outbuildings with exposed timber are worth checking for borer. Sheds full of stored equipment make perfect quiet nesting spots.
Field mice and rats looking for shelter are the main call, especially after harvest and in winter. Flies around livestock and paper wasps in sheds follow in summer, and homes on the edge of open land see more spiders and the odd scorpion.
Tell-tale signs
- Small dark mosquitoes resting on shaded walls, under the eaves or behind curtains during the day.
- 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.
- A high-pitched whine near your ear just as you fall asleep.
- Swarms in the evening near a water feature, drain or neglected pool.
- Day-time bites on the ankles while sitting in the garden, which points to Aedes breeding nearby.
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.
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.
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.
- 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.
Prevention that actually works
- 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.
- Keep pool water circulating and treated, and drain the water that collects on top of pool covers.
- 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.
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.
Mosquito Control questions from Firgrove
Do you service smallholdings and outbuildings in Firgrove?
Yes. We cover the house, sheds, stables and feed stores, and we plan bait placement so it stays out of reach of pets and livestock.
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.
Do you come out to Firgrove for mosquito control?
Yes. Firgrove is part of our regular Helderberg route, along with Somerset West, Macassar, Strand, Helderberg. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
Why are there suddenly mice in my Firgrove house in autumn?
Cooler weather and work on the surrounding fields push mice toward warm, sheltered buildings. Sealing gaps under doors and around pipes early in autumn keeps most of them out.
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.
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.
