Sugar is the most powerful lure for a roach. They will gladly make themselves at home in bag of sugar or enjoy the drops of coke that remain in a soda can on the counter overnight. They can smell dried sugary drinks on the floor, and a sweet apple core in the kitchen garbage is delightful.
The idea that roaches only infest filthy homes is a myth. While poor sanitation can contribute to infestations, even spotless homes can attract cockroaches under the right conditions.
