when I lived in my auto, there are roaches and when I cooked some eggs these roaches came to see what was for breakfast. Here in Finland we have no roaches, too cool for them. Actually it was quite ■■■■ living in my automobile over two years with all insects.
I would run across a room just to flatten one of those bugs under my shoe. Fortunately, they are only out in the garage.
If you got something for them to eat, they will show up.
Saddest thing I ever saw was a baby cockroach dead in the bottom of a tub of sealed candy bags-he starved to death!
