Use gel baits in cracks and crevices. One roach could lead others back to the bait and help expose the colony’s location.
Don’t wait. Treat as soon as you see one. If you do, you might stop a full infestation before it blooms.
Maintain excellent sanitation, no crumbs, no spills, no food residues. That reduces the food sources and makes the environment less hospitable even for hiding ones.”
Combine methods—trapping, baits, sealing. Relying on just one method often fails once more roaches emerge from hidden nests.
Lastly, monitor over weeks. If you don’t catch more within 10–14 days, maybe it was a wanderer. But if others appear, treat aggressively.
