I admit I have a bit of an embarrassing problem - the cockroach in the kitchen. We kept the kitchen clean, no food particles left after eating, and the floors thoroughly wiped. But on occasions, one or two cockroach would be proudly standing nearby the sink and I have to shoo it by the bug-spray or the newspaper roll. There's nothing to feast on the sink since it's empty and clean, but they made their way on it. Before I start to call the pest control - anything that to discourage the cockroaches more? Turning on the kitchen lights did the small trick, but it isn't a permenant solution.
