Las chinches de cama puede parecer un viejo problema pasado de moda, sin embargo ahora están de vuelta — y con venganza. Hace cincuenta años, estas plagas chupadoras de sangre estaban casi erradicadas en los Estados Unidos gracias, en parte, al uso de pesticidas como el DDT. Hoy, se arrastran entre las sabanas — y atormentan a los desgraciados soñadores — en todo el país...
