Mowbray is busy and mixed: old cottages, student digs, a station and taxi rank, small shops and the Liesbeek running along one side. That combination keeps us busy with rats, cockroaches and, more than most suburbs, bed bugs.
Mowbray: what drives flying insects here
Mosquitoes breed in slow pools along the river in late summer. Flies cluster around the takeaway bins near the station.
The Liesbeek River runs along the eastern side, joining the Black River near the Observatory boundary, and its banks are a natural highway for rats. Table Mountain's Devil's Peak side rises behind Groote Schuur, bringing heavy winter rainfall and damp walls. Old stormwater drains under the streets connect the river to the houses.
A lot of the housing is Victorian and Edwardian semi-detached cottages and terraces, many converted into student lets or split into rooms. Shared walls, old suspended timber floors and crumbling air bricks give rodents and cockroaches easy movement between homes. Blocks of flats near Main Road add shared ducts and bin rooms. The commercial strip around the station has takeaways and small grocers with busy back yards.
Rats are the top call, especially in houses near the river and the Main Road shops. German cockroaches are rife in shared kitchens of student houses. Bed bugs and fleas move with tenants and their furniture, and fishmoths like the damp older homes.
A note from the field
If a cloud of big shiny flies suddenly appears in one room, check the ceiling. A rat or bird that died in the roof is the usual cause, and the flies stop once the carcass is removed.
Signs to look for
- You hear whining at night and wake up with fresh bites on exposed arms and ankles.
- Small flies hover over the fruit bowl, the recycling bin or the drip tray under a bar tap.
- Small moths flutter out of the pantry or out of a cupboard full of woollens.
- Flies keep gathering around the same window, light or rubbish area even after you have cleaned and sprayed.
Our process, step by step
We start by identifying the insect properly, because a drain fly needs a completely different fix from a house fly or a mosquito. Breeding sites come first: drains are cleaned out and treated with a larvicide or bio-enzyme product, standing water is tipped or treated, and waste areas are sorted out. Only then do we use residual sprays on resting surfaces such as window frames and wall tops, fly bait stations away from food, and ULV fogging where a large space needs a quick knockdown. In commercial kitchens and food stores we install insect light traps with glue boards so there is constant monitoring between visits. Wasp nests are treated with a dust or spray directly into the nest and removed once the colony is dead.

Prevention that actually works
- Fit fly screens on kitchen windows and keep a self-closing door or strip curtain on back doors that open onto bins.
- Check eaves, carports and garden furniture in early spring for small paper wasp nests while they are still easy to deal with.
- Tip out pot plant saucers, birdbaths and anything else that holds water for more than a few days.
- Store flour, cereal and pet food in sealed containers so pantry moths have nothing to breed in.
- Keep wheelie bins closed, rinse them out in summer, and park them away from the kitchen door.
How much will it cost?
The price depends on which insect we are treating, because a single wasp nest is a very different job from a fly problem in a large food factory. The size of the property, how many breeding sites there are and how hard they are to get at, such as roof voids or sealed drains, all affect the time on site. Commercial sites with light traps and scheduled visits are usually best quoted as a contract, and we give free quotes once we know what is flying.
Flying insects peak from about October to March, when hot weather speeds up breeding and a fly can go from egg to adult in around a week. The south-easter keeps numbers down on the exposed side of the city but pushes flies indoors in sheltered suburbs, and mosquitoes often surge after the last winter rains leave water lying around. Wasps build their nests in spring and are at their most defensive in late summer when colonies are biggest.
Flying Insect Control questions from Mowbray
What are the tiny flies around my bathroom drain?
They are almost always drain flies, also called moth flies. They breed in the gel-like film inside drains, so cleaning the pipe properly works far better than spraying the walls.
Do the rats in Mowbray come from the Liesbeek River?
Many of them do. The river banks and connected stormwater drains give them shelter, so houses on the river side need sealed air bricks and well-closed bins.
Do you come out to Mowbray for flying insect control?
Yes. Mowbray is part of our regular Southern Suburbs route, along with Observatory, Rosebank, Rondebosch, Pinelands. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
Do insect light traps actually work?
Yes, in the right place. They catch flies that get past your doors and screens and, just as usefully, the glue boards show us what is getting in and how many, which is why food businesses rely on them.
How quickly can you treat a student house in Mowbray for bed bugs?
Our average turnaround is about 48 hours, depending on the season. Send us a photo on WhatsApp first so we can confirm it is bed bugs and tell you how to prepare the rooms.
How quickly can you come out?
We aim for around 48 hours, though it varies with the season, and we can do after-hours or weekend visits on request.
