Cockroach Control in South African Homes

Cockroach Control in South African Homes: ULTRAKILL vs Gel Bait – Which Works Best?

Cockroaches are one of South Africa’s most stubborn and unhygienic household pests. From kitchen cabinets in Johannesburg flats to storerooms in Nelspruit, these nocturnal invaders can carry bacteria, contaminate food, and trigger allergies.

The good news? With the right products and a smart approach, you can get rid of them for good.

In this post, we compare two of the most effective roach control options: ULTRAKILL Insecticide Spray and Gel Bait – so you can decide what works best for your home.

🪳 Why Are Cockroaches So Hard to Kill?

Cockroaches hide in cracks, drains, warm appliances, and behind walls. They breed quickly and only come out at night, making infestations hard to detect until they’re serious.

You may notice:

  • Black droppings like pepper grains

  • A musty, oily smell

  • Egg casings (ootheca) behind fridges or cupboards

  • Fast scuttling insects when you switch on the light

⚔️ The Showdown: ULTRAKILL vs Gel Bait

Let’s break down how each method works and when to use it.

🧴 Option 1: ULTRAKILL Insecticide Spray

How it works:
ULTRAKILL’s contact spray is designed to instantly kill roaches on sight and leave a residual film that kills any that walk over it.

Best for:

  • Immediate relief from visible cockroaches

  • Surface treatment around bins, cracks, behind stoves

Pros:

  • Kills on contact

  • Leaves a long-lasting residue (up to 4 weeks)

  • Also works on ants, fleas, and silverfish

Cons:

  • Doesn’t reach eggs or hidden nests

  • Can be repellent, driving cockroaches deeper into walls if overused

💧 Option 2: Cockroach Gel Bait

How it works:
Gel bait is applied in small dots in crevices where cockroaches hide. The bait attracts them, and once consumed, the poison spreads to others in the nest via droppings and cannibalism.

Best for:

  • Targeting hidden colonies

  • Long-term elimination of the infestation at its source

Pros:

  • Silent, invisible, and odorless

  • Targets the entire colony, not just visible roaches

  • One application can last weeks

Cons:

  • Slower results (1–3 days)

  • Needs correct placement and patience
