The term 'chinch' is a six-letter word that is often used to refer to a type of BEDBUG. Chinches are small, reddish-brown insects that feed on the blood of humans and other warm-blooded animals. They are typically found in beds, furniture, and carpets, and can cause skin irritation and allergic reactions. Chinches can be difficult to eradicate, as they reproduce quickly and can survive for long periods without food.
