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.
Crawling insects in Mowbray: what we see
German cockroaches spread fast in shared kitchens and through the walls of semis. Fishmoths, ants and garden spiders are steady background visitors.
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.
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 note from the field
People are often surprised that the cleanest kitchens can have German cockroaches. They usually arrive in cardboard boxes, second-hand appliances or grocery deliveries, and a warm motor compartment behind a fridge is all they need.
One of the most common mistakes is spraying insecticide over ant bait. It contaminates the bait and the ants stop feeding on it, so the colony survives.
Signs to look for
- Crickets chirp loudly from inside the house at night but go quiet when you get close.
- Fishmoths drop out of books, boxes or linen cupboards when you move them.
- Ant trails run from a crack in the floor or wall to the dog bowl, sugar bowl or dishwasher.
- Cockroaches dart away when you switch on the kitchen or bathroom light at night.
Cockroaches move between drains, bins and food surfaces and can spread bacteria that cause stomach upsets. Their droppings and shed skins are a recognised trigger for allergies and asthma. Fishmoths damage paper, documents, photographs and starched fabrics, which matters a lot in offices, schools and archives. In food premises, a crawling insect sighting by a customer or an inspector can do lasting damage to a business's reputation.
Our process, step by step
Crawling insects walk through treated areas and carry baits back to their nests, which is exactly why baits and dusts work so well on them. We use gel baits in cracks and hinges for cockroaches and slow-acting ant baits that the workers take home to the queen. Insect growth regulators stop young cockroaches from maturing and breeding, which matters for German cockroaches that multiply fast. Residual sprays are applied as a barrier along entry points, door thresholds and drain areas rather than across open floors. Dusts go into wall voids, ceiling spaces and plug points where liquids should not be used.

Stopping a repeat visit
- Put drain covers or mesh over floor drains and keep the water traps full, especially in guest bathrooms that are seldom used.
- Store books and documents in sealed plastic boxes in dry rooms rather than in damp garages.
- Seal gaps under exterior doors with a brush strip, because most crawling insects simply walk in.
- Do not leave dishes in the sink overnight, since a wet sink is a feeding station for cockroaches.
- Move firewood, compost and piles of bricks away from the house walls.
Pricing, honestly
Cost is driven by the species and how established the infestation is, with German cockroaches in a busy kitchen usually needing more work than a one-off ant trail. The size of the property, the number of units or rooms affected, and access to roof spaces and drains also matter. Where a follow-up treatment is needed to catch hatching insects, or where a business wants a regular service contract, we build that into a free quote upfront.
Shop-bought ant baits can handle a small, new trail and are worth a try. For cockroaches, especially German cockroaches, DIY sprays usually make things worse by scattering them and killing only the adults while the egg cases hatch. In flats and food businesses, I would not bother with DIY at all.
Frequently asked questions
Do you come out to Mowbray for crawling 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.
Why do ants keep coming back after I spray them?
Spraying kills the foragers but leaves the queen and the nest untouched. Baits work better because the workers carry the product back and share it with the colony.
What counts as a crawling insect?
Anything that mainly walks rather than flies: cockroaches, ants, fishmoths, crickets, earwigs, millipedes and scorpions. They hide in cracks and voids, which is why they are treated with baits, dusts and barriers.
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.
Will one treatment get rid of cockroaches?
For American cockroaches it often will. German cockroaches usually need a follow-up because their egg cases are protected and hatch after the first treatment.
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.
