Chinches. ¿¡En serio!?

Bed bugs are small parasites that feed on human blood, causing discomfort and itching. They have spread globally, infesting homes, hotels, and public spaces. Historically, bed bugs have been a problem since the Stone Age, worsening with urbanization and central heating. Although synthetic insecticides once controlled them, many are now banned, and bed bugs have developed resistance. Increased global travel has facilitated their spread, making them a persistent modern issue.
