If you’re in Durban and you’ve never had a cockroach problem, honestly, you’re lucky, and it probably won’t last. Our climate is basically perfect for them. Warm, humid, coastal: cockroaches thrive in exactly the conditions we live in every day. So if you’re dealing with them right now, you’re not doing anything wrong. It’s just Durban.
Let’s talk about what actually helps.
Where They Live (And Why They Chose Your Kitchen)
Cockroaches move in for three simple reasons, and if you understand these, you understand about 80% of the problem.
Moisture. This is the big one for us specifically, because of our humidity. Roaches need water more than they need food, so anywhere there’s a damp patch (under the sink, around a leaking pipe, near the shower drain, even just condensation build-up behind the fridge) is prime real estate for them.
Food. Obvious, but worth saying properly. It’s not just crumbs on the counter. It’s the grease film on your stove, the residue in an “empty” cereal box, pet food left out overnight, the bin that doesn’t get taken out often enough. Roaches don’t need much to survive.
Shelter. This is the one people forget. Roaches want dark, tight, undisturbed spaces: cracks in tiling, gaps behind skirting boards, the underside of appliances, cardboard boxes stacked in a garage or storeroom. Cardboard especially, they love it, they can live and breed inside it, so if you’re storing boxes long-term, that’s worth a second look.
Take away moisture, food, and shelter, and you’ve made your home a much harder place for them to survive. You won’t solve an existing infestation this way, but you’ll stop it from getting worse, and you’ll stop a new one from starting.
Home Remedies Worth Trying (Before You Call Anyone)
I’ll be straight with you, if it’s a handful of roaches and not a full infestation, there are things worth trying first.
- Deep clean the usual spots. Behind the fridge and stove, under the sink, inside cupboards. Get the grease and crumbs out properly, not just a wipe-down.
- Fix the leaks. Even a small drip under a sink is enough water source to keep a colony going. This is often the single biggest thing people miss.
- Seal the gaps. A tube of caulk around pipes, skirting boards, and any cracks in tiling goes a long way. By doing this you’re blocking their access to your walls and voids, which is where they actually nest.
- Boric acid and sugar bait. This is an old one, but it does work for smaller problems. Mix boric acid powder with a bit of sugar and place it in small dishes near where you’ve seen activity, not out in the open where kids or pets can reach it. The sugar draws them in, the boric acid does the rest. Just handle it carefully, it’s toxic if ingested, so keep it well away from children and animals, and replace it every couple of weeks.
- Store food properly. Airtight containers, not just a folded-over cereal bag. And don’t leave pet food bowls out overnight.
Do these consistently for a few weeks and you’ll knock back a small problem significantly. What these won’t do is fix an established infestation, and here’s why.
This isn’t only about hygiene, either. Cockroach allergy is a genuine health issue here in Durban specifically. According to South African allergy specialists, cockroach allergy is present in 80% of asthmatic children in the Durban area, and exposure is a recognised risk factor for asthma-related hospital admissions. That’s a strong reason to deal with an infestation properly rather than just knocking back what you can see.
Why a Real Infestation Needs More Than Doom
This is the part that catches people out. You spray what you can see, the roaches disappear for a few days, and then they’re back, sometimes worse than before. It’s not that the spray didn’t work. It’s that you only ever killed the roaches that were out in the open.
A female cockroach’s eggs are sitting in a case, tucked deep in a wall void or under a floor, completely untouched by anything you sprayed on the counter. Those eggs hatch, and the cycle just starts again. That’s the whole problem with DIY: it treats what you can see, not where the colony actually lives.
What we do differently:
- We don’t just spray visible areas, we treat the entry points, voids, and harbourage spots where the colony is actually breeding.
- We use products that interrupt the full lifecycle.
- Everything we use is odourless and chosen with your family and pets in mind.
- We get into the places a can of Doom can’t reach: wall cavities, deep cracks, the spots behind fixed appliances.
If you’ve sprayed, cleaned, sealed the gaps, and you’re still seeing roaches two or three weeks later, that’s usually your sign the nest itself hasn’t been dealt with, and it’s time to get a Durban pest control expert to come.
The Bottom Line
Durban’s climate means cockroaches are always going to be a fact of life here.
But there’s a real difference between managing a small, early problem yourself and trying to fight an established colony with what’s in your cleaning cupboard. Know which one you’re dealing with, and act accordingly.
If you’re not sure which camp you’re in, send us a photo or give us a call. We’d rather tell you it’s nothing than have you dealing with this for another two months.
Thank you, and God bless.

Frequently Asked Questions (FAQs)
Why do I have cockroaches even though my house is clean?
Cleanliness helps, but it’s not the whole story. Roaches mainly need moisture, and Durban’s humidity means even a small leak under a sink or condensation behind a fridge can be enough to sustain them, regardless of how tidy the rest of your home is.
Is it normal to have cockroaches in Durban?
Yes, it’s extremely common. Durban’s warm, humid, coastal climate is close to ideal for cockroaches, so seeing them from time to time doesn’t mean you’re doing anything wrong.
Will boric acid and sugar actually get rid of cockroaches?
It can help with a small, early problem. The sugar draws them in and the boric acid does the rest, but it only affects roaches that come into contact with it out in the open. It won’t reach an egg case tucked inside a wall void, which is why it’s not reliable for an established infestation.
Why do the roaches keep coming back after I spray them?
Store bought sprays kill what’s visible, but they don’t reach where the colony is actually breeding, usually deep in wall cavities, under floors, or behind fixed appliances. The eggs in those spots hatch regardless of what you sprayed on the counter, so the cycle continues.
How do I know if it’s a small problem or a full infestation?
If you’ve cleaned properly, fixed leaks, sealed gaps, and you’re still seeing roaches two or three weeks later, that’s usually a sign the nest itself hasn’t been dealt with and it’s time to bring someone in.
Are professional cockroach treatments safe for kids and pets?
A proper treatment should be. Products used by registered operators are chosen with families and pets in mind and are typically odourless, unlike leaving boric acid bait out where children or animals could access it.
How long does it take to get rid of a cockroach infestation?
It depends on how established the colony is, but because treatment needs to interrupt the full lifecycle, including eggs that haven’t hatched yet, it’s rarely a one visit fix. A proper assessment will give you a realistic timeline.
