There are different types of cockroaches, and each feeds on something different. Perhaps this is why you've spotted them at different places of your home!
On the left is the American cockroach; it is shiny red or chocolate brown and eats anything that is organic matter (but also sweets, bread, and fruit). Next to it is a common cockroach, which is dark brown with light lateral edges. It eats starchy food as well as things like glue on books and wallpaper. On the right is the German cockroach; it is brownish yellow with two parallel black bands running down its back, and eats starchy food.

- there is a distinct, unpleasant smell where the cockroaches have come into contact with
