Find where cockroaches hide
Cockroaches hide in warm, humid, dark spots: behind the fridge, under sinks, in cabinet gaps, and in drains. Mapping the harbourage is key so treatment targets the population, not just the roaches you see.
Use gel baiting, not just sprays
Sprays only kill roaches they directly hit. Gel baiting is far more effective because roaches carry the bait back to the nest and infect the colony. Place gel at active points and avoid spraying nearby so they keep feeding on it.
Stay clean and reduce humidity
Clean up crumbs, dry sinks at night, cover drains, and store food tightly. Cockroaches need water and food; removing both makes it hard for the population to survive.
Frequently asked questions
Why are there more cockroaches after spraying?
Sprays scatter roaches from the nest without killing the colony. Gel baiting targets the whole population, so it is more thorough.
