answer:I have also never, to my knowledge seen a cockroach in a dwelling before. A lot of people who don’t have enough money end up in places that are not kept up as well, or in places that are older. These places often have lots of cracks and holes which are perfect for rodents and insects. The house I rent was built during the civil war. We have some problems with mice and insects. More so than any other home I have had. And we DO live here becuz it’s a place we can afford. We live below the poverty level in the USA. But I am in the midwest, which surely makes a difference in what types of invaders are around.
