The common bug, Cimex lectularius, is found in temperate climates in the United States .
Widespread use of insecticides such as DDT often sovles the problem .
They invade high-end clothing stores like the lingerie outlet Victoria’s Secret .
Human scent can be a favourite .
They hide in linen by day and come out at night to bite people, often while they are sleeping, leaving red, itchy welts .
There can be no hiding place - exterminate .
