Hout Bay is a valley town with a working harbour at one end and horse paddocks and leafy plots further up. Fishing boats, stables, a river and mountain on three sides make for a wider mix of pests than most Atlantic Seaboard suburbs.
Hout Bay: what drives flying insects here
Stable flies and house flies build up around horse paddocks and manure heaps in summer.
The valley is ringed by the Karbonkelberg, the Sentinel, Chapman's Peak and the back of Table Mountain, with the Disa River running down to the beach. Winter rain is heavy and the valley floor stays damp. The harbour, the river mouth and the paddocks all feed flies, gulls and rodents.
Housing ranges from big family homes on large plots in the upper valley, to townhouse complexes, holiday homes near the beach and older cottages closer to the harbour. Many homes have thatched lapas, timber decks and outbuildings.
Rats around the harbour and along the river, flies near stables, and mosquitoes near the river and wetland areas are typical.

Something most people miss
In food businesses, light traps are as much about information as killing flies. A quick look at the glue board tells us whether numbers are rising and what kind of fly is getting in.
House flies prefer to rest on edges and corners, like window frames and the edge of a ceiling board. That is exactly where a residual treatment does its best work.
How the treatment works
Fly control works from the ground up, so we start with sanitation: bins, compost, drains, grease traps, animal waste and anything else they can breed in. Drains and grease traps are scrubbed and treated with a bio-enzyme or larvicide that breaks down the breeding film, and we treat larvae where they are found. For adult flies we use bait stations or bait paint away from food areas and a residual spray on the surfaces where flies rest, such as window frames, walls near bins and outside walls by doors. Commercial kitchens and food plants get insect light traps with glue boards, placed where they catch flies without drawing them towards open food. ULV fogging is kept for large spaces that need a fast knockdown, never as the only treatment.

Stopping a repeat visit
- Double-bag meat scraps and bones and put them out on collection day rather than leaving them in the bin all week.
- Pick up dog mess daily, because it is one of the most common fly breeding sites in Cape Town gardens.
- Keep ripe fruit in the fridge in hot weather and wipe up spilt wine, beer and cooldrink straight away.
- Rinse and disinfect wheelie bins regularly in summer and keep the lids shut, since a closed bin breeds far fewer flies.
- Clean floor drains and grease traps on a schedule, not only when they smell.
Pricing, honestly
The cost of fly control depends mainly on how many breeding sites there are and how much work it takes to reach them. A home with a drain fly problem is a short job, while a food factory, abattoir or busy restaurant usually needs light traps, drain treatments and regular visits. Contracts work out better value for businesses that need ongoing monitoring, and we quote for free after a look at the site.
Fly numbers climb from late spring and peak in the hot months between December and March, when a house fly can complete its life cycle in about a week. Windless days after a south-easter has died down tend to bring them indoors in numbers. Drain flies and fruit flies are less seasonal and can be a problem all year in warm kitchens and bars.
Frequently asked questions
Are fly baits safe around pets?
We place baits in stations or on surfaces pets cannot reach, and keep them well away from food areas. Tell us about your pets and we will plan around them.
Do you help restaurants with health inspections?
Yes. We set up light traps, carry out scheduled treatments and give you a post-treatment report for every visit, which is what inspectors want to see.
Where are all these flies coming from?
Usually from something close by: a bin, compost heap, pet waste, a drain or a dead animal in the roof. Flies rarely travel far when they have somewhere good to breed.
Why are there so many flies in Hout Bay in summer?
The stables, paddocks and harbour all give flies breeding material, and warm summer weather speeds that up. Removing manure and fish waste quickly, plus fly control around the stables, makes a big difference.
Do you come out to Hout Bay for fly control?
Yes. Hout Bay is part of our regular City Bowl & Atlantic Seaboard route, along with Imizamo Yethu, Llandudno, Constantia, Camps Bay. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
How do I get rid of fruit flies?
Remove the ripe fruit, clean up spills and check under the fridge and in the recycling. A simple vinegar trap catches the stragglers, and if they persist, a drain is usually involved.
