In central Port Elizabeth, the key thing to understand about insects is that buildings are shared. Restaurants sit below flats, offices share ducts with shops, and old plumbing and service shafts connect the lot. Cockroaches, bed bugs and flies move through those connections, so treating one unit on its own often fails. The most effective approach is to look at the whole building, or at least the units around the problem, and treat them together.
The old city centre
Central is the historic heart of the city, with older buildings that house offices, flats, shops and restaurants, often all in the same block. Many of these buildings have been altered and re-plumbed several times over the decades. That leaves gaps behind panels, unused pipe runs, voids above ceilings and old service ducts: perfect highways and hiding places for insects.
The Bay's mild climate and the warmth that older buildings hold mean indoor insects here stay active throughout the year.
The four insects that dominate
German cockroaches in kitchens and ducts
This is the most common insect problem in the centre by a long way. German cockroaches breed fast in restaurant and takeaway kitchens, then spread through service ducts and plumbing into neighbouring flats and offices. Small, light brown and quick, they hide in the warmest, tightest gaps: behind fryers, inside equipment housings and under sinks. Gel baits in cracks and crevices, with an odourless residual treatment where needed and a follow-up visit for newly hatched nymphs, is what works. See cockroach control in Mill Park and the central suburbs.
Bed bugs in flats
Bed bugs arrive in luggage, second-hand furniture and bags, and in a building with a lot of tenant turnover they can spread from flat to flat along wall cavities and pipe runs. Signs are bites in lines overnight, small rust-coloured spots on sheets and mattress seams, and a faint musty smell in bad cases. Early treatment of the affected flat and checks on the units on either side is the way to stop it spreading. More on bed bug treatment near the city centre.
Flies in food businesses
House flies gather around bin areas behind shops and restaurants, and small drain flies breed in the slime inside floor drains and grease traps. Drain flies in particular confuse people, because spraying the adults does nothing while the drain keeps producing more. Cleaning the drains properly and treating the breeding site sorts them out. Our page on flying insect control in Mill Park covers both.
Fishmoths in offices and storerooms
Files, archive boxes, old stationery and storerooms full of cardboard are fishmoth heaven, especially in rooms that are rarely opened. They graze on paper and glue, damaging documents and book bindings. A crack-and-crevice treatment of shelving and storerooms, and moving files into plastic crates, keeps them down.
For landlords, body corporates and managing agents
If you look after a building in the centre, an insect complaint from one tenant is usually a sign of a wider problem. Treating unit by unit, as complaints come in, is slow and expensive and lets the insects move around ahead of you. A building-wide treatment, including common areas, refuse rooms and service ducts, followed by regular monitoring, is far more effective. We can plan visits around tenants and trading hours.
For restaurants and food businesses
Kitchens in the centre need scheduled insect control, not a once-off spray when things get bad. We set up visits that fit around your trading hours and keep a record of each one.
The most common mistake
Using an aerosol or a bug bomb in a single flat or kitchen. Instead of killing the colony, it often pushes cockroaches and bed bugs into the walls and the units next door, where they settle and come back later. Baits and targeted treatments, coordinated across units, work far better.
A tip for city-centre buildings
Seal the gaps where pipes and cables pass through walls and floors, especially in kitchens, bathrooms and refuse rooms. A tube of sealant around pipe penetrations closes the routes insects use to move between units, and it makes every treatment last longer.
What does it cost?
It depends on the type and size of the building, how many units are affected, which insects are involved and whether you want a once-off treatment or ongoing monitoring. A single flat with a small cockroach problem is a quick job. A whole building, or a busy restaurant kitchen, takes more planning and usually works best on a schedule. We'll quote once we've seen it.

Questions we get asked
Who is responsible for insects in a block of flats?
It depends on your lease and the building's rules, but because insects move between units, landlords and body corporates usually get the best results by arranging building-wide treatment.
Can you treat a restaurant without closing it?
Usually, yes. We schedule treatments around trading hours, and gel baits are placed in cracks away from food preparation surfaces.
Why do I have tiny flies around the drains?
They're likely drain flies breeding in the slime inside the drain. Cleaning the drain thoroughly removes their breeding site, which is what stops them.
Will bed bugs spread to the neighbouring flat?
They can, through wall cavities and pipe runs. That's why we recommend checking the units next to an affected flat.
Do I need to move out of my flat for treatment?
No. Keep people and pets off treated surfaces until they're dry, usually a couple of hours.
