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.
Cockroaches in Hout Bay
Cockroaches are more common in Hout Bay's harbour precinct than in the residential valley. American cockroaches come up through drains near the harbour, especially on warm nights, and German cockroaches live in restaurant and takeaway kitchens and spread into flats nearby.
We treat drains and floor traps for American cockroaches and use gel baits and dusts for German cockroaches. Restaurants and fish businesses can book regular visits with a written report each time.
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.
From the technician
Gel bait in small dots inside hinges and cracks is one of the safest ways to treat a home with children and pets. It stays where it is put and is not sprayed into the air.
In rented flats, cockroaches are often a building problem, not a tenant problem. Landlords and body corporates get far better results treating the whole building together.

How we handle cockroach control in Hout Bay
Gel bait is the backbone of most cockroach treatments. It is placed in tiny spots inside hinges, cracks and appliance housings where cockroaches feed, and because they feed on each other's droppings, the bait passes through the population. We add an insect growth regulator for German cockroaches so the young cannot mature and breed. For American cockroaches, we treat floor drains, manholes and entry points with a residual product, and use dusts in wall voids and ceiling spaces. We avoid broad spraying of open surfaces because it is less effective and adds unnecessary chemicals to your home.
- Identify the cockroach
German or American makes a big difference to where we treat. A WhatsApp photo is usually enough to tell.
- Inspect harbourage
We check hinges, behind and under appliances, motor compartments, drains, and electrical points with a torch.
- Map the infestation
We note which rooms or units are affected, and whether neighbouring flats or shared drains are involved.
- Bait and growth regulator
Gel bait goes into feeding spots, and a growth regulator breaks the breeding cycle.
- Drains and voids
Floor drains, manholes and wall voids are treated to stop American cockroaches getting in.
- Follow-up and report
German cockroach jobs usually need a follow-up visit to catch hatching nymphs, and you get a report with proofing advice.
Stopping a repeat visit
- Clean behind and under the stove and fridge every few months, since grease build-up there feeds a lot of cockroaches.
- Keep floor drains covered and run water down little-used drains weekly so the traps stay full.
- Seal gaps where pipes and cables pass through walls under sinks and behind appliances.
- Check cardboard boxes, second-hand appliances and furniture before bringing them indoors.
- Take rubbish out every evening and keep outside bins with tight lids away from doors.
How much will it cost?
Price depends largely on the species and how big the population is, with German cockroaches in a well-established kitchen taking more time and usually a follow-up visit. The size of the home or business, the number of units involved and the amount of equipment and cupboards to treat all affect the quote. Restaurants and food businesses often go onto a regular contract, which tends to work out better value than repeated once-off treatments, and the quote is free.
American cockroaches are most active in the hot summer months, when they come up from warm drains and sewers at night. German cockroaches breed all year round because they live indoors near stoves, fridges and geysers. Heavy winter rain can flood drains and push cockroaches into homes in large numbers.
Cockroach Control questions from Hout Bay
Why do I see big cockroaches near the Hout Bay harbour?
They're American cockroaches that live in the drains. Drain treatment and keeping floor traps full of water stop most of them.
Do cockroaches fly in Cape Town?
American cockroaches can fly or glide short distances, mostly on hot, humid nights. German cockroaches have wings but rarely fly.
How many treatments will I need?
American cockroaches often need just one. German cockroaches usually need a second visit a few weeks later to deal with nymphs hatching from protected egg cases.
Do I need to leave the house during treatment?
For gel bait treatments, no. If residual products are used in certain areas, we will tell you how long to keep children and pets away, usually just until it has dried.
Why am I seeing more cockroaches after the treatment?
For a few days, cockroaches affected by the bait often come out into the open before they die. This is normal, and numbers should drop clearly within one to two weeks.
How did I get German cockroaches in a clean house?
They usually hitch a ride in grocery boxes, appliances, furniture or bags, or move in from a neighbouring unit. Cleanliness helps control them, but it does not stop them from arriving.
