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.
The local picture in Mowbray
Old pine floorboards, skirtings and roof timbers in the Victorian cottages are prime territory for common furniture beetle. A beetle certificate inspection before buying here is well worth it.
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.
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.
From the technician
Borer damage in thatch is often blamed on the reed, but the reed is rarely the problem. It is the poles and laths holding it up that the beetles are after.
What gives them away
- Fine powder dropping from the poles or laths onto floors and furniture below.
- Birds pulling reed out of the roof or nesting under the eaves.
- Insects such as cockroaches or spiders falling from the ceiling.
- Tunnels or loose patches in the thatch where rodents have been moving.
- Rustling or scratching in the roof at night.
Borer in the poles and laths weakens the timbers that carry the weight of the thatch, which is heavy, and serious damage can mean replacing structural members. Rodents nesting in thatch chew electrical cables, and in a thatch roof that is a fire risk to take seriously. Insects dropping from an open thatch ceiling are a nuisance in homes and a real problem in guest lodges and restaurants. Bird nests in thatch can bring mites into bedrooms below.
How the treatment works
We start by inspecting the underside of the roof, the poles, the laths and the eaves, looking for borer exit holes, frass and rodent or bird activity. Affected poles and laths are treated with a borer spray or injection designed for timber, applied to the wood rather than soaked through the thatch. For insects living in the thatch, we use a targeted residual treatment on the underside, keeping it as light as will do the job. Rodents are handled with traps and tamper-resistant bait stations placed at wall plates and entry points, and we advise on bird netting or proofing at the eaves. Fire safety of the thatch itself, such as retardant treatment, is a separate specialist job and we will tell you if it looks overdue.

Stopping a repeat visit
- Fit bird netting or wire at the eaves if birds keep pulling reed or nesting there.
- Ask your thatcher to check the poles and laths for borer whenever the roof is being repaired or re-combed.
- Do not store firewood or boxes against the walls under the thatch, as they give insects and rodents cover.
- Keep trees and creepers trimmed back from the thatch so rodents cannot step straight onto the roof.
- Have open thatch ceilings in lapas and lodges checked once a year, since problems are easy to see early.
How much will it cost?
The price depends on the size of the roof, how much of the structure is exposed and how many poles and laths show borer activity. A small lapa with an open underside is a very different job from a double-storey home with a closed ceiling. Rodent and bird work is added where needed, and timber that is too damaged to treat has to be replaced by a builder or thatcher.
Spraying the underside of your own thatch with a garden insecticide does very little for borer, which lives inside the poles, and soaking thatch in products not meant for it can do more harm than good. We would leave borer and rodent work in thatch to someone who does it regularly. Keeping the roof clear of overhanging trees is the one thing every owner can do themselves.
Questions we get asked in Mowbray
Do you come out to Mowbray for thatch treatment?
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 I need to move out?
Usually not. We will tell you which rooms to keep clear during treatment and for how long.
Can you treat a lapa or braai area?
Yes, lapas are often the easiest to treat because the whole structure is open underneath.
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.
Is there a guarantee?
Our treatments carry a minimum 3-month guarantee, and the report records exactly what was treated.
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.
