How to get rid of cockroaches fast: what works, what doesn't, and why the supermarket shelf won't save you.
You flick on the kitchen light at 2am. A dark shape scuttles across the floor. By the time your brain registers what you've seen, it's already gone.
If you've spotted one cockroach, you can be sure there are more hiding nearby. They're fast, resilient, and masters of staying out of sight. And the supermarket products promising a quick fix? They're often a waste of money.
For decades, the pest control industry has offered a predictable solution: show up, spray everywhere, leave, and hope it worked. Homeowners are left with a lingering chemical smell, vague assurances, and the creeping doubt that the problem might return.
We think there's a better way. One built on science, not guesswork. One where we find the problem first, then solve it.
Why DIY methods usually fail.
The problem with most off-the-shelf cockroach products is simple: they only kill the insects you see. This is a problem for three reasons.
1: cockroaches reproduce quickly. A single German cockroach female can produce up to 300 offspring in her lifetime. She doesn't need a partner to do it.
2: they hide. Cockroaches spend 75% of their time in cracks, crevices and wall voids. If you're only treating the surfaces you can see, you're missing most of the population.
3: sprays can make it worse. Repellent sprays can scatter cockroaches, pushing them deeper into your walls. You might think the problem is solved because you're not seeing them. In reality, they've just moved somewhere harder to reach.
What actually works (and what doesn't).
Method | Does it work? | Why |
|---|---|---|
Aerosol sprays | ❌ Temporary | Kills what you see, misses the nest. Often repellent, which can scatter the population. |
Bug bombs/foggers | ❌ No | Active ingredient doesn't penetrate cracks and crevices. Leaves residue on surfaces. |
Sticky traps | ✅ Monitoring only | Useful for identifying problem areas, but won't eliminate an infestation. |
Gel baits (professional-grade) | ✅ Yes | Cockroaches are attracted to the bait, feed and return to their hiding spot where they die. Other cockroaches then feed on the poisoned carcass, spreading the treatment through the colony. |
A Smarter approach: find the source, not just the scouts.
We don't spray and pray. We follow a methodical process that eliminates cockroaches at the source.
Step 1: Find the harbourage.
Cockroaches cluster in warm, dark, humid areas close to food and water. Common harbourages include:
- Behind refrigerators and dishwashers
- Under sinks and around pipes
- Inside cabinets and drawers
- In wall voids and electrical boxes.
Our techinicans use moisture meters and visual inspections to locate these hotspots.
Step 2: Apply targeted baits.
Instead of saturating your kitchen with chemicals, we apply professional-grade gel baits in the cracks and crevices where cockroaches hide. The bait is more attractive than any food in your home, they can't resist it.
The active ingredient is slow-acting. This allows cockroaches to return to their harbourage and die, where other cockroaches will feed on them and die in turn. It's not dramatic, but it's devastatingly effective.
Step 3: Prevent reinfestation
We'll identify what's attracting cockroaches to your home in the first place. Common attractants include food crumbs and spills, open rubbish bins, leaky pipes and taps, and cluttered storage areas. A few simple changes can make your home far less inviting.
What you can do right now.
If you're dealing with a cockroach problem, here are steps you can take immediately:
1. Remove food sources.
- Store all food in sealed containers
- Wipe down benches and sweep floors nightly
- Empty rubbish bins regularly
- Don't leave pet food out overnight.
2. Remove water sources.
- Fix leaking taps and pipes
- Wipe up standing water
- Ensure bathroom and kitchen are well-ventilated.
3. Declutter.
Cockroaches love cardboard boxes, stacked papers, and cluttered storage areas. Reduce hiding spots where possible.
4. Call a professional.
If you've done all of the above and still see cockroaches, you have a hidden infestation that requires professional treatment.
Safety without compromise.
Many cockroach treatments use chemicals that can be harmful to children and pets. Our targeted approach means baits are placed in inaccessible areas (cracks, crevices, behind appliances), minimal product is used (only where it's needed), and we never spray where your family spends time.
We don't spray where they play. It's not just a tagline. It's how we operate.
A problem that won’t solve itself.
Cockroaches are resilient, but they're not invincible. The key is targeting the colony, not just the scouts. Supermarket sprays might give you temporary relief, but they won't solve the underlying problem.
The industry may not have evolved for decades. But it has now.
