How does cockroach killer gel works?

It’s a "tasty trap." Roaches eat the bait, head back to their secret hideouts, and eliminate the rest of the colony from within.

Is cockroach killer gel better than sprays?

Yes. Sprays only hit what’s in front of you; gel reaches the source of the infestation.

One application stays effective for several weeks as long as it remains clean and dry.

No. Our professional-grade gels are odorless and won't leave messy stains on your surfaces.

You can use cockroach baits and traps available in stores. For a serious problem, it's best to call for professional help.

Cockroach killer gel is highly effective because it uses the natural, social, and cannibalistic habits of cockroaches against the entire colony.

Edible Formula: The gel is a highly attractive bait, typically combining an insecticide (the poison) with palatable ingredients like sugar, proteins, and fats.
The Hook: Roaches are strongly drawn to the gel, viewing it as a reliable food source, so they readily consume it.

Active Ingredient: The poison (like Fipronil or Imidacloprid) is slow-acting. It doesn't kill the cockroach immediately.
The Crucial Delay: This delay is key. The infected roach has enough time to eat the bait and return to its harborage (the nest) before dying.

Once the infected cockroach is back in the nest, the poison spreads to the rest of the colony through several mechanisms:

Fecal Transfer: The infected cockroach excretes waste, which contains traces of the poison. Other cockroaches (especially nymphs) often eat this contaminated waste.
Cannibalism: Cockroaches eat dead or dying members of their colony. When they consume an infected cockroach carcass, they also ingest a lethal dose of the poison.
Oral Transfer: Roaches often share food and touch each other, transferring traces of the poison through contact and grooming.
